President's Letter

Dear Shareowner,

Stock and bond markets around the globe this year have experienced one of their
most tumultuous periods in history. Investors have witnessed volatility of a
magnitude that many have never before seen. Distance often provides the best
vantage point for perspective. Still, we believe that the benefits of basic
investment principles that have stood the test of time -- even in the midst of
market turmoil -- cannot be underestimated.

First, invest for the long term. The founder of Pioneer Investments, Philip L.
Carret, began his investment career during the 1920s. One lesson he learned is
that while great prosperity affords an advantageous time for selling stocks,
extreme economic slumps can create opportunities for purchase. Indeed, many of
our portfolio managers, who follow the value-conscious investing approach of
our founder, are looking at recent market conditions as an opportunity to buy
companies whose shares we believe have been unjustifiably beaten down by
indiscriminate selling, but that we have identified as having strong prospects
over time. While investors may be facing a sustained market downturn, we
continue to believe that patience, along with staying invested in the market,
are important considerations for long-term investors.

A second principle is to stay diversified across different types of
investments. The global scope of the current market weakness poses challenges
for this basic investment axiom. But the turbulence makes now a good time to
reassess your portfolio and make sure that your investments continue to meet
your needs. We believe you should work closely with your financial advisor to
find the mix of stocks, bonds and money market assets that is best aligned to
your particular risk tolerance and investment objective.

As the investment markets sort through the continuing crisis in the financial
industry, we are staying focused on the fundamentals and risk management. With
more than 80 years of experience behind us, we have learned how to navigate
turbulent markets. At Pioneer Investments, risk management has always been a
critical part of our culture -- not just during periods of extraordinary
volatility. Our investment process is based on fundamental research,
quantitative analysis and active portfolio management. This three-pillared
process, which we apply to each of our portfolios, is supported by an
integrated team approach and is designed to carefully balance risk and reward.
While we


2    Pioneer Real Estate Shares | Annual Report | 12/31/08


see potential chances for making money in many corners of the market, it takes
research and experience to separate solid investment opportunities from
speculation.

We invite you to learn more about Pioneer and our time-tested approach to
investing by consulting with your financial advisor or visiting us online at
www.pioneerinvestments.com. Thank you for investing with Pioneer.

Respectfully,

/s/ Daniel K. Kingsbury

Portfolio Management Discussion | 12/31/08

The U.S. real estate market posted its worst year of performance in 2008, which
coincided with the most disappointing year for the broader stock market since
the Great Depression. With many long-standing pillars of the financial
community collapsing, the credit markets sharply contracting, and the economy
tipping into recession, real estate investment trust (REIT) prices came under
significant pressure, as Matthew Troxell of AEW Capital Management, L.P., the
Fund's subadvisor, explains in the following interview.

Q  How did the Fund perform amidst the extreme volatility and challenging market
   conditions?

A  For the 12 months ended December 31, 2008, Class A shares posted a return of
   -38.31% at net asset value, but held up better than the -39.93% average
   return for the 232 funds in Lipper's Real Estate Funds category over the
   same period. The Fund modestly underperformed its benchmark, the Morgan
   Stanley Capital International (MSCI) U.S. REIT Index, which returned
   -37.97% over the same 12-month period. The underperformance was largely
   attributable to the Fund's underweighting to the outperforming health care
   sector and overweighting to the underperforming regional mall sector.
   Negative sector allocation was partially offset by solid stock selection
   results, particularly in the industrial, regional mall and health care
   sectors.

Q  How did the problems in the credit markets directly impact the REIT sector?

A  There was a dramatic decrease in the amount of third-party commercial
   mortgage capital available for property investment. Consequently, the cost
   of available debt increased considerably. That resulted in a sharp decline
   in commercial real estate transactions, which, in turn, put downward
   pressure on stock price valuations. The market also punished companies with
   excessive debt on their balance sheets and/or those with significant
   development exposure.

Q  Which holdings helped the Fund's performance over the year ended December 31,
   2008?

A  Top performers for the Fund included Public Storage, which owns self-
   storage facilities throughout the country and benefited from solid earnings
   results, minimal debt and significant cash flow; Omega Healthcare, whose
   positive performance reflected the defensive characteristics of the
   company's solid balance sheet and stable income stream; and the industrial
   REIT Liberty Property Trust, which, although down for the fiscal year
   overall, was


4    Pioneer Real Estate Shares | Annual Report | 12/31/08


   one of the top performers in the battered industrial sector, relatively
   speaking, after a dismal year in 2007.

Q  Which Fund holdings proved most disappointing over the year ended
   December 31, 2008?

A  The biggest disappointments for the Fund during the period were Developers
   Diversified Realty, Starwood Hotels & Resorts Worldwide, and Brookfield
   Office Properties. Developers Diversified, a shopping center REIT, suffered
   in large part due to concerns over the company's near-term debt maturities
   and the weakening retail environment. Starwood's decline was reflective of
   problems in the hotel sector in general, which suffered as a result of the
   slowing economy and the impact of rising fuel costs on travel. Brookfield
   lost ground due to the company's significant exposure to New York City
   office space in its portfolio. Concerns that job losses will increase
   vacancy levels in the city also weighed on the company's stock price. We
   continue to believe the companies represent solid values relative to their
   peers, and maintain the Fund's overweight positions in all three stocks.

Q  How are the property sectors holding up given the recession?

A  In our view, the underlying property market fundamentals have deteriorated
   due to the ongoing economic slowdown, particularly in those markets most
   affected by the housing market downturn. In the retail sector, property
   vacancies have increased quickly for several consecutive quarters, as
   American consumers have become increasingly reluctant to spend, and
   retailers have curtailed expansion plans and, in some cases, closed stores.
   Continued sluggishness is expected into 2009 as a weak housing sector and
   very depressed consumer sentiment may put restraints on spending. We do
   believe, however, that the sector should be fairly well positioned when
   demand recovers, since supply growth has been moderate.

   Conditions in the apartment sector have been impacted, both negatively and
   positively, by troubles in the single-family housing sector. Rising
   foreclosures and stricter loan underwriting standards are forcing some home
   buyers and would-be buyers to become renters, while rentals of investor-owned
   homes and condominiums are providing housing alternatives to
   would-be-renters. We feel the conditions are likely to persist until a
   clear bottom is reached in single-family fundamentals.

   Office property vacancies have begun to climb in central business district
   locations, especially those closely tied to the fortunes of financial
   employers and, to an even greater degree, those in suburban locations. With
   unemployment rising, demand remains the primary concern, as supply has
   remained in check and may even further weaken in the wake of the credit
   crunch. Within the industrial sector, fundamentals have been deteriorating
   for much of the past year and space availability has been climbing.


                      Pioneer Real Estate Shares | Annual Report | 12/31/08    5


   In the hotel sector, occupancy figures were approximately 8% lower than a
   year ago, and room rates have been weakening after holding up for much of
   2008. Consequently, revenues per available room have been declining. We
   expect hotel occupancies to remain under pressure as both leisure and
   business travelers become more cautious in a slowing economy.

Q  What is your outlook?

A  We believe that the market environment in 2009 will be challenging --
   particularly for real estate owners -- given our belief that debt capital
   will be scarcer and higher-priced than it has been in the past. However, we
   think the likely effect of this challenging environment has been, to a
   degree, already priced into real estate securities. In this market, we will
   remain focused on companies that have high-quality assets, solid management
   teams and stable balance sheets. We will continue to make incremental
   changes to the Fund as values and catalysts continue to change.

Please refer to the Schedule of Investments on pages 15-19 for a full listing
of Fund securities.

The Fund invests in REIT securities, the value of which can fall for a variety
of reasons, such as declines in rental income, fluctuating interest rates, poor
property management, environmental liabilities, uninsured damage, increased
competition, or changes in real estate tax laws. At times, the Fund's
investments may represent industries or industry sectors that are interrelated
or have common risks, making it more susceptible to any economic, political, or
regulatory developments or other risks affecting those industries or sectors.

Past performance is no guarantee of future results, and there is no guarantee
that market forecasts discussed will be realized.

Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers
may not be in effect for all funds. Certain fee waivers are contractual through
a specified period. Otherwise, fee waivers can be rescinded at any time. See
the prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

The MSCI U.S. REIT Index is a widely used index comprising a broad
representation of the most actively traded real estate trusts, and is designed
to be a measure of real estate equity performance. Index returns assume
reinvestment of dividends and, unlike Fund returns, do not reflect any fees,
expenses or sales charges. You cannot invest directly in the Index. Note to
Shareowners: Effective April 1, 2008, the Fund's benchmark changed to the MSCI
REIT Index. The securities represented in the new index better reflect the
types of securities in which the Fund is likely to invest. Previously, the
benchmark was the Dow Jones Wilshire Real Estate Securities Index (RESI), which
changed investment models in mid-2007, thus rendering it less appropriate as a
benchmark for the Portfolio. Returns for the Dow Jones Wilshire RESI were no
longer available for Pioneer's shareowner reporting purposes after June 30,
2008.

The performance data quoted represents past performance, which is no guarantee

"If Held" results represent the percent change in net asset value per share.
Returns would have been lower had sales charges been reflected. "If redeemed"
returns reflect the deduction of applicable contingent deferred sales charge
(CDSC). Effective December 1, 2004, the period during which a CDSC is applied
to withdrawals was shortened to 5 years. The maximum CDSC for Class B shares
continues to be 4%. For more complete information, please see the prospectus
for details. Note: Shares purchased prior to December 1, 2004 remain subject to
the CDSC in effect at the time you purchased those shares. For performance
information for shares purchased prior to December 1, 2004, please visit

12    Pioneer Real Estate Shares | Annual Report | 12/31/08


Comparing Ongoing Fund Expenses

As a shareowner in the Fund, you incur two types of costs:

(1) ongoing costs, including management fees, distribution and/or service
    (12b-1) fees, and other Fund expenses; and

(2) transaction costs, including sales charges (loads) on purchase payments.

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 at the beginning of the Fund's latest six-month period and held
throughout the six months.

Using the Tables
- --------------------------------------------------------------------------------
Actual Expenses

The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

(1) Divide your account value by $1,000
    Example: an $8,600 account value [divided by] $1,000 = 8.6

(2) Multiply the result in (1) above by the corresponding share class's number
    in the third row under the heading entitled "Expenses Paid During Period"
    to estimate the expenses you paid on your account during this period.

* Expenses are equal to the Fund's annualized expense ratio of 1.63%, 2.71%,
  2.49% and 1.02% for Class A, Class B, Class C and Class Y shares,
  respectively, multiplied by the average account value over the period,
  multiplied by 184/366 (to reflect the one-half year period).

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.

You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
funds.

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) that are charged at the time of the transaction. Therefore, the
table below is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

Notes to Financial Statements | 12/31/08

1. Organization and Significant Accounting Policies

Pioneer Real Estate Shares (the Fund) is a Delaware statutory trust registered
under the Investment Company Act of 1940 as a diversified, open-end management
investment company. The investment objective of the Fund is to seek long-term
growth of capital. Current income is a secondary objective.

The Fund offers four classes of shares -- Class A, Class B, Class C, and Class Y
shares. Each class of shares represents an interest in the same portfolio of
investments of the Fund and has identical rights (based on relative net asset
values) to assets and liquidation proceeds. Share classes can bear different
class-specific fees and expenses such as transfer agent and distribution fees.
Differences in class-specific fees and expenses will result in differences in
net investment income and, therefore, the payment of different dividends by each
class. The Amended and Restated Declaration of Trust of the Fund gives the Board
the flexibility to specify either per share voting or dollar-weighted voting
when submitting matters for shareholder approval. Under per share voting, each
share of a class of the Fund is entitled to one vote. Under dollar-weighted
voting, a shareholder's voting power is determined not by the number of shares
owned, but by the dollar value of the shares on the record date. Share classes
have exclusive voting rights with respect to matters affecting only that class,
including with respect to the distribution plan for that class. There is no
distribution plan for Class Y shares. Class B shares convert to Class A shares
approximately eight years after the date of purchase

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the
Fund to, among other things, make estimates and assumptions that affect the
reported amounts of assets and liabilities, the disclosure of contingent assets
and liabilities at the date of the financial statements, and the reported
amounts of income, expenses and gains and losses on investments during the
reporting year. Actual results could differ from those estimates.

Because the Fund may invest a substantial portion of its assets in Real Estate
Investment Trusts (REITs), the Fund may be subject to certain risks associated
with direct investments in REITs. REITs may be affected by changes in the value
of their underlying properties and by defaults of their borrowers or tenants.
REITs depend generally on their ability to generate cash flow to make
distributions to shareowners, and certain REITs have self-liquidation
provisions by which mortgages held may be paid in full and distributions of
capital returns may be made at any time. In addition, the performance of a REIT
may be affected by its failure to qualify for tax-free pass-through of income
under


28    Pioneer Real Estate Shares | Annual Report | 12/31/08


the Internal Revenue Code or its failure to maintain exemption from
registration under the Investment Company Act of 1940. The Fund's prospectuses
(unaudited) contain information regarding the Fund's principal risks. Please
refer to those documents when considering the Fund's risks.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements, which are consistent with
those policies generally accepted in the investment company industry.

A. Security Valuation

  Security transactions are recorded on trade date. The net asset value of the
  Fund is computed once daily, on each day the New York Stock Exchange (NYSE)
  is open, as of the close of regular trading on the NYSE. In computing the
  net asset value, securities are valued at the last sale price on the
  principal exchange where they are traded. Securities that have not traded on
  the date of valuation, or securities for which sale prices are not generally
  reported, are valued at the mean between the last bid and asked prices.
  Securities for which market prices and/or quotations are not readily
  available are valued using fair value methods pursuant to procedures adopted
  by the Board of Trustees. Trading in foreign securities is substantially
  completed each day at various times prior to the close of the NYSE. The
  values of such securities used in computing the net asset value of the
  Fund's shares are determined as of such times. The Fund may also use fair
  value methods to value a security, including a non-U.S. security, when the
  closing market price on the principal exchange where the security is traded
  no longer reflects the value of the security. At December 31, 2008, there
  were no securities that were valued using fair value methods. Temporary cash
  investments are valued at cost which approximates market value.

  Dividend income is recorded on the ex-dividend date, except that certain
  dividends from foreign securities where the ex-dividend date may have passed
  are recorded as soon as the Fund becomes aware of the ex-dividend data in
  the exercise of reasonable diligence. Interest income is recorded on the
  accrual basis.

  Gains and losses on sales of investments are calculated on the identified
  cost method for both financial reporting and federal income tax purposes.

B. Federal Income Taxes

  It is the Fund's policy to comply with the requirements of the Internal
  Revenue Code applicable to regulated investment companies and to distribute
  all of its taxable income and net realized capital gains, if any, to its
  shareowners. Therefore, no federal income tax provision is required. Tax
  years for the prior three fiscal years remain subject to examination by tax
  authorities.


                     Pioneer Real Estate Shares | Annual Report | 12/31/08    29


  The amounts and characterizations of distributions to shareowners for
  financial reporting purposes are determined in accordance with federal
  income tax rules. Therefore, the sources of the Fund's distributions may be
  shown in the accompanying financial statements as from or in excess of net
  investment income or net realized gain on investment transactions, or as
  from paid-in capital, depending on the type of book/tax differences that may
  exist. A portion of the dividend income recorded by the Fund is from
  distributions by publicly traded REITs, and such distributions for tax
  purposes may also consist of capital gains and return of capital. The actual
  return of capital and capital gains portions of such distributions will be
  determined by formal notifications from the REITs subsequent to the calendar
  year-end. Distributions received from the REITs that are determined to be a
  return of capital, are recorded by the Fund as a reduction of the cost basis
  of the securities held.

  At December 31, 2008, the Fund had a net capital loss carryforward of
  $7,060,199, which will expire in 2016 if not utilized.

  The tax character of distributions paid during the years ended December 31,
  2008 and 2007 was as follows:



                                        2008            2007
                                            
   Distributions paid from:
   Ordinary income                $3,426,917      $ 3,370,381
   Long-term capital gain                 --       30,157,255
   Return of capital               2,170,453               --
- -------------------------------------------------------------
      Total                       $5,597,370      $33,527,636
=============================================================


  The following shows the components of distributable earnings on a federal
  income tax basis at December 31, 2008:



                                                  2008
                                       
   Distributable earnings:
   Capital loss carryforward              $  (7,060,199)
   Unrealized depreciation                  (24,405,810)
- -------------------------------------------------------
      Total                               $ (31,466,009)
=======================================================


  The difference between book basis and tax-basis unrealized depreciation is
  attributable to the tax deferral of losses on wash sales.

C. Fund Shares

  The Fund records sales and repurchases of its shares on trade date. Pioneer
  Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a
  wholly owned indirect subsidiary of UniCredit S.p.A., (UniCredit). PFD
  earned $20,363 in underwriting commissions on the sale of Class A shares
  during the year ended December 31, 2008.


30    Pioneer Real Estate Shares | Annual Report | 12/31/08


D. Class Allocations

  Income, common expenses and realized and unrealized gains and losses are
  calculated at the Fund level and allocated daily to all classes of shares
  based on their respective percentage of adjusted net assets at the beginning
  of the day. Distribution fees are calculated based on the average daily net
  asset value attributable to Class A, Class B and Class C shares of the Fund,
  respectively. Class Y shares are not subject to a distribution plan (see
  Note 4). Shareowners of each class participate in all expenses and fees paid
  to the transfer agent, Pioneer Investment Management Shareholder Services,
  Inc. (PIMSS), for its services, which are allocated based on the number of
  accounts in each class and the ratable allocation of related out-of-pocket
  expenses (see Note 3).

  Distributions to shareowners are recorded as of the ex-dividend date.
  Distributions paid by the Fund with respect to each class of shares are
  calculated in the same manner, at the same time, and in the same amount,
  except that Class A, Class B, Class C and Class Y can bear different
  transfer agent and distribution fees.

E. Securities Lending

  The Fund lends securities in its portfolio to certain broker-dealers or
  other institutional investors. When entering into a securities loan
  transaction, the Fund typically receives cash collateral from the borrower
  equal to at least the value of the securities loaned, which is invested in
  temporary cash investments. Credit Suisse, New York Branch, as the Fund's
  security lending agent, manages the Fund's securities lending collateral.
  The income earned on the investment of collateral is shared with the
  borrower and the lending agent in payment of any rebate due to the borrower
  with respect to the securities loan, and in compensation for the lending
  agent's services to the Fund. The Fund also continues to receive interest or
  payments in lieu of dividends on the securities loaned. Gain or loss on the
  value of the loaned securities that may occur during the term of the loan
  will be for the account of the Fund. The amount of the collateral is
  required to be adjusted daily to reflect any price fluctuation in the value
  of the loaned securities. The Fund has the right, under the lending
  agreement, to terminate the loan and recover the securities from the
  borrower with prior notice. The Fund will be required to return the cash
  collateral to the borrower and could suffer a loss if the value of the
  collateral, as invested, has declined.

F. Repurchase Agreements

  With respect to repurchase agreements entered into by the Fund, the value of
  the underlying securities (collateral), including accrued interest, is
  required to be at least equal to or in excess of the value of the repurchase
  agreement. The collateral for all repurchase agreements is held in
  safekeeping in the customer-only account of the Fund's custodian or
  subcustodians.


                     Pioneer Real Estate Shares | Annual Report | 12/31/08    31


  The Fund's investment adviser, Pioneer Investment Management, Inc. (PIM), is
  responsible for determining that the value of the collateral remains at
  least equal to the repurchase price.

2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's
portfolio. Management fees are calculated daily at the annual rate of 0.80% of
the Fund's average daily net assets. PIM pays a portion of the fee it receives
from the Fund to AEW Management and Advisors L.P. as compensation for
sub-advisory services to the Fund.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. Included in "Due to affiliates" reflected on
the statement of Assets and Liabilities is $2,105 in management fees,
administrative costs and certain other fees payable at December 31, 2008.

3. Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially
all transfer agent and shareowner services to the Fund at negotiated rates.

In addition, the Fund reimbursed PIMSS for out-of-pocket expenses related to
shareholder communications activities such as proxy and statement mailings,
outgoing phone calls and omnibus relationship contracts. For the year ended
December 31, 2008, such out of pocket expenses by class of shares were as
follows:



 Shareholder Communications:
                                   
 Class A                              $ 85,453
 Class B                                25,318
 Class C                                11,973
 Class Y                                   131
- ----------------------------------------------
    Total                             $122,875
==============================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $44,332 in transfer agent fees and shareholder communications
expense payable to PIMSS at December 31, 2008.

4. Distribution Plan

The Fund adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment
Company Act of 1940 with respect to its Class A, Class B and Class C shares.
Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets
attributable to Class A shares as compensation for personal services and/or
account maintenance services or distribution services with regard to Class A
shares. Pursuant to the Plan, the Fund pays PFD 1.00% of the average daily net
assets attributable to Class B and Class C shares. The fee for Class B


32    Pioneer Real Estate Shares | Annual Report | 12/31/08


and Class C shares consists of a 0.25% service fee and a 0.75% distribution fee
paid as compensation for personal services and/or account maintenance services
or distribution services with regard to Class B and Class C shares. Prior to
February 1, 2008, PFD was reimbursed under the Distribution Plan for
distribution expenses in an amount up to 0.25% of the average daily net assets
attributable to Class A shares. Included in "Due to affiliates" reflected on
the Statement of Assets and Liabilities is $775 in distribution fees payable to
PFD at December 31, 2008.

In addition, redemptions of each class of shares (except Class Y shares) may be
subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be
imposed on redemptions of certain net asset value purchases of Class A shares
within 18 months of purchase. Class B shares that are redeemed within five
years of purchase are subject to a CDSC at declining rates beginning at 4.0%,
based on the lower of cost or market value of shares being redeemed.
Redemptions of Class C shares within one year of purchase are subject to a CDSC
of 1.00%, based on the lower of cost or market value of shares being redeemed.
Proceeds from the CDSC are paid to PFD. For the year ended December 31, 2008,
CDSCs in the amount of $41,952 were paid to PFD.

5. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS
resulting in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the year ended December 31, 2008, the Fund's expenses
were reduced by $8,700 under such arrangements.

6. Line of Credit Facility

The Fund along with certain other funds in the Pioneer Family of Funds (the
Funds) collectively participate in a $115 million committed, unsecured
revolving line of credit facility. Borrowings are used solely for temporary or
emergency purposes. The Fund may borrow up to the lesser of $115 million or the
limits set by its prospectus for borrowings. Interest on borrowings is payable
at the Federal Funds Rate plus 1/2% on an annualized basis. The Funds pay an
annual commitment fee for this facility. The commitment fee is allocated among
participating Funds based on their respective borrowing limits. For year ended
December 31, 2008, the Fund had no borrowings under this agreement.

7. New Pronouncement

In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures
about Derivative instruments and Hedging Activities (SFAS 161), was issued and
is effective for fiscal years beginning after November 15, 2008. SFAS 161
requires enhanced disclosures about an entity's derivative and hedging
activities. Management is currently evaluating the impact the adoption of
SFAS 161 will have on the Fund's financial statement disclosures.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareowners of
Pioneer Real Estate Shares:
- --------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities of Pioneer
Real Estate Shares (the "Fund"), including the schedule of investments, as of
December 31, 2008, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Fund's management. Our responsibility is to express
an opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. We were not engaged to perform an audit of the Fund's internal
control over financial reporting. Our audits included consideration of internal
control over financial reporting as a basis for designing audit procedures that
are appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating
the overall financial statement presentation. Our procedures included
confirmation of securities owned as of December 31, 2008, by correspondence
with the custodian and broker or by other appropriate auditing procedures where
replies from brokers were not received. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Real Estate Shares at December 31, 2008, the results of its operations
for the year then ended, the changes in its net assets for each of the two
years in the period then ended, and financial highlights for each of the five
years in the period then ended, in conformity with U.S. generally accepted
accounting principles.

                                                           /s/ Ernst & Young LLP

Approval of Sub-Advisory Agreement (unaudited)

Pioneer Investment Management, Inc. (PIM) serves as the Fund's investment
adviser pursuant to an investment advisory agreement between PIM and the Fund.
PIM has retained AEW Capital Management, L.P. to serve as the sub-adviser to
the Fund pursuant to a sub-advisory agreement between PIM and the sub-adviser.

At a meeting held on January 8, 2008, the Trustees of the Fund approved an
amended and restated investment advisory agreement between the Fund and PIM.
Shareholders of the Fund approved the amended and restated investment advisory
agreement on May 13, 2008. The material factors and conclusions with respect
thereto that formed the basis for the Trustees' approval of the amended and
restated investment advisory agreement are included in the Fund's semi-annual
report for the period ended June 30, 2008.

At a meeting held on November 11, 2008, based on their evaluation of the
information provided by PIM and the sub-adviser, the Trustees of the Fund,
including the independent Trustees voting separately, unanimously approved the
continuation of the sub-advisory agreement for the Fund for another year. In
considering the continuation of the sub-advisory agreement, the Trustees
considered various factors that they determined were relevant, including the
factors described below. The Trustees did not identify any single factor as the
controlling factor in determining to approve the continuation of the sub-
advisory agreement.

Nature, Extent and Quality of Services
The Trustees considered the nature, extent and quality of the services provided
to the Fund by the sub-adviser, taking into account the investment objective
and strategy of the Fund and the information related to the Fund provided to
the Trustees at each quarterly meeting. The Trustees reviewed the terms of the
sub-advisory agreement. The Trustees also reviewed the sub-adviser's investment
approach for the Fund and its research process. The Trustees considered the
resources of the sub-adviser and the personnel of the sub-adviser who provide
investment management services to the Fund.

Based on these considerations, the Trustees concluded that the nature, extent
and quality of services provided by the sub-adviser to the Fund were
satisfactory and consistent with the terms of the sub-advisory agreement.

Performance of the Fund
The Trustees considered the performance results of the Fund over various time
periods. They reviewed information comparing the Fund's performance with the
average performance of its peer group of funds as classified by


                     Pioneer Real Estate Shares | Annual Report | 12/31/08    35


Morningstar, Inc. (Morningstar), an independent provider of investment company
data, and with the performance of the Fund's benchmark index. The Trustees
considered that the Fund's annualized total return was in the third quintile of
its Morningstar category for the one and three year periods ended June 30,
2008. (In all quintile rankings referred to throughout this disclosure, first
quintile is most favorable to the Fund's shareowners. Thus, highest relative
performance would be first quintile and lowest relative expenses would also be
first quintile.) The Trustees concluded that the investment performance of the
Fund was satisfactory.

Sub-advisory Fee and Expenses
The Trustees considered the fees payable to the sub-adviser under the sub-
advisory agreement. They also considered that PIM, not the Fund, paid the
sub-adviser out of the management fees paid to PIM under the investment
advisory agreement. The Trustees considered information regarding the
management fees and expenses of the Fund in comparison to the management fees
of its peer group of funds as classified by Morningstar and the expense ratios
of a peer group of funds selected on the basis of criteria determined by the
independent Trustees for this purpose using data provided by Strategic Insight
Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent
third party.

The Trustees considered that the Fund's management fee for the twelve months
ended June 30, 2008 was in the second quintile relative to the management fees
paid by other funds in its peer group Morningstar category for the comparable
period. The Trustees also considered that the Fund's expense ratio for the
twelve months ended June 30, 2008 was in the first quintile relative to its
Strategic Insight peer group.

The Trustees also reviewed the advisory fees charged by the sub-adviser to its
separate account clients with investment strategies that were similar to the
Fund. The Trustees noted that the fee rates for those separate accounts
generally were in line with the sub-advisory fees paid to the sub-adviser with
respect to the Fund.

The Trustees concluded that the sub-advisory fee payable by PIM to the sub-
adviser of the Fund was reasonable in relation to the nature and quality of
services provided by the sub-adviser. The Trustees also concluded that the
Fund's expense ratio was reasonable.

Profitability
The Trustees considered information provided by PIM regarding the profitability
of PIM with respect to the advisory services provided by PIM to the Fund,
including the methodology used by PIM in allocating certain of its costs to the
management of the Fund. They also considered PIM's profit margin in connection
with the overall operation of the Fund. The Trustees further considered the
sub-advisory fees received by the sub-adviser with respect to the


36    Pioneer Real Estate Shares | Annual Report | 12/31/08


Fund and the percentage that such fees represented of the sub-adviser's overall
revenues (for the 12-month period ended December 31, 2007). They also reviewed
the financial results realized by PIM and its affiliates from non-fund
businesses. The Trustees considered the profit margins with respect to the Fund
in comparison to the limited industry data available and noted that the
profitability of any adviser was affected by numerous factors, including its
organizational structure and method for allocating expenses. The Trustees
recognized that each of PIM and the sub-adviser should be entitled to earn a
reasonable level of profit for the services provided to the Fund. The Trustees
concluded that the profit margins with respect to the management of the Fund
were not unreasonable.

Economies of Scale
The Trustees considered the economies of scale with respect to the management
of the Fund, whether the Fund had appropriately benefited from any economies of
scale, and whether there was potential for realization of any further economies
of scale. The Trustees considered that, although the Fund pays a management fee
at a fixed rate as a percentage of the Fund's net assets, without any
breakpoints, the management fee rate paid by the Fund for the twelve months
ended June 30, 2008 was in the second quintile relative to the management fees
paid by other funds in its peer group Morningstar category for the comparable
period and that, on a hypothetical basis, such fee would be in the second
quintile relative to the peer group at higher asset levels. The Trustees
concluded that, at current and reasonably foreseeable asset levels, breakpoints
in the management fee currently were not necessary.

Other Benefits
The Trustees considered that the sub-adviser reported that it does not receive
any other benefits from its relationship with the Fund.

Conclusion
After consideration of the factors described above as well as other factors,
the Trustees, including all of the independent Trustees, concluded that the
sub-advisory agreement for the Fund between PIM and the sub-adviser, including
the fees payable thereunder, was fair and reasonable and voted to approve the
continuation of the sub-advisory agreement for the Fund.

 PIONEER FUNDS
            APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES
                       PROVIDED BY THE INDEPENDENT AUDITOR

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

The Pioneer Funds recognize the importance of maintaining the independence of
their outside auditors. Maintaining independence is a shared responsibility
involving Pioneer Investment Management, Inc ("PIM"), the audit committee and
the independent auditors.

The Funds recognize that a Fund's independent auditors: 1) possess knowledge of
the Funds, 2) are able to incorporate certain services into the scope of the
audit, thereby avoiding redundant work, cost and disruption of Fund personnel
and processes, and 3) have expertise that has value to the Funds. As a result,
there are situations where it is desirable to use the Fund's independent
auditors for services in addition to the annual audit and where the potential
for conflicts of interests are minimal. Consequently, this policy, which is
intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and
procedures to be followed by the Funds when retaining the independent audit firm
to perform audit, audit-related tax and other services under those
circumstances, while also maintaining independence.

Approval of a service in accordance with this policy for a Fund shall also
constitute approval for any other Fund whose pre-approval is required pursuant
to Rule 210.2-01(c)(7)(ii).

In addition to the procedures set forth in this policy, any non-audit services
that may be provided consistently with Rule 210.2-01 may be approved by the
Audit Committee itself and any pre-approval that may be waived in accordance
with Rule 210.2-01(c)(7)(i)(C) is hereby waived.

Selection of a Fund's independent auditors and their compensation shall be
determined by the Audit Committee and shall not be subject to this policy.

                 firm, the scope of the Audit
                 Services would likely
                 increase.  The Services are

                 professional standards (AICPA,

  categories and the "Approval of Audit, Audit-Related, Tax and Other
  Services" Policy above will be applied. Any services outside the specific
  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

o At least quarterly, the Audit Committee shall review a report summarizing the
  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

were no services provided to an affiliate that required the
Fund's audit committee pre-approval.
