Exhibit 99.1

               Potlatch Reports Fourth Quarter Results

    SPOKANE, Wash.--(BUSINESS WIRE)--Feb. 5, 2007--Potlatch
Corporation (NYSE:PCH), a real estate investment trust (REIT), today
reported net earnings of $44.1 million, or $1.13 per diluted common
share, for the fourth quarter of 2006, compared to third quarter net
earnings of $24.2 million, or $.62 per diluted common share, and net
earnings of $9.9 million, or $.34 per diluted common share, for the
fourth quarter of 2005. Earnings for the fourth quarter of 2006
included $39.3 million, or $24.0 million net of tax ($.62 per diluted
common share), representing the company's total share of the
negotiated settlement of the softwood lumber trade dispute between the
U.S. and Canada. This was partially offset by an income tax adjustment
of $3.9 million, or $.10 per diluted common share, primarily related
to the transfer of assets from the REIT to the company's taxable REIT
subsidiary, which includes all of the manufacturing businesses. This
affected the company's deferred tax liability adjustment as a result
of the REIT conversion. Earnings for the third quarter of 2006
included a tax benefit of $9.2 million, or $.23 per diluted common
share, primarily related to an agreement reached with the Internal
Revenue Service regarding tax issues pertaining to open tax years,
which also affected the deferred tax liabilities adjusted as a result
of the REIT conversion.

    Excluding the $39.3 million (and related tax effect) from the
settlement of the softwood lumber trade dispute, the $3.9 million
income tax adjustment in the fourth quarter and the $9.2 million tax
benefit in the third quarter, earnings for the fourth quarter of 2006
were higher than the third quarter due primarily to better results for
the Land Sales and Development and Consumer Products segments. The
favorable comparison to the third quarter was partially offset by
lower earnings for the Pulp and Paperboard segment. Fourth quarter
2006 earnings were better than the fourth quarter of 2005 due
primarily to improved results for the Resource and Pulp and Paperboard
segments.

    Net revenues for the fourth quarter of 2006 were $390.0 million,
compared with $399.1 million for the third quarter of 2006 and $389.3
million for the fourth quarter of 2005, respectively.

    Net earnings for the year ended December 31, 2006, totaled $139.1
million, or $3.79 per diluted common share, compared to net earnings
of $33.0 million, or $1.13 per diluted common share, for the year
ended December 31, 2005. Earnings for 2006 included a net tax benefit
of $56.5 million, or $1.55 per diluted common share, related primarily
to the company's January 1, 2006, conversion to a REIT. Net revenues
for 2006 were $1.61 billion, compared with net revenues of $1.50
billion for 2005.

    Cash provided by operating activities for the year ended December
31, 2006, was $188.7 million, compared to $66.4 million for the same
period in 2005. During the fourth quarter of 2006, the company paid a
regular quarterly distribution of $19.0 million. The aggregate total
of Potlatch's regular quarterly distributions in 2006, its first year
as a REIT, was $76.1 million, compared to an aggregate total of $17.5
million for its regular quarterly dividends in 2005.

    Resource

    The Resource segment reported operating income of $19.6 million
for the fourth quarter of 2006, compared with $19.3 million in the
third quarter and $13.4 million earned in the fourth quarter of 2005.
Compared to the third quarter, segment income for the fourth quarter
of 2006 was slightly higher due primarily to higher Arkansas fee
harvest levels and a smaller loss for the company's Boardman, Oregon,
hybrid poplar operation in the fourth quarter. These improvements were
mostly offset by lower selling prices for logs in Idaho for the fourth
quarter of 2006 compared to the third quarter. The higher income for
the fourth quarter of 2006 compared to the same period in 2005 was due
primarily to a significantly higher harvest of fee timber in Idaho,
partially offset by decreased fee harvest levels and lower selling
prices for logs in Arkansas.

    Land Sales and Development

    The Land Sales and Development segment, which is a new segment
beginning in 2006, was created to provide more focus on maximizing the
value of Potlatch's land assets. The segment reported operating income
of $9.1 million for the fourth quarter of 2006, compared with
operating income of $0.8 million in the third quarter of 2006 and
$14.9 million for the fourth quarter of 2005. The higher income for
the fourth quarter of 2006 compared to the third quarter was due
largely to the sale of a conservation easement in Arkansas for $6.7
million during the fourth quarter. Income for the fourth quarter of
2006 was lower than the fourth quarter of 2005 because most of the
company's land sales activity was on hold in 2006 pending the initial
assessment of all its lands for alternative values, which was
completed in late 2006.

    Wood Products

    Excluding the $39.3 million from the settlement of the softwood
lumber trade dispute, the Wood Products segment recorded an operating
loss of $5.4 million for the fourth quarter of 2006, compared with a
loss of $5.2 million in the third quarter and income of $0.4 million
in the fourth quarter of 2005. "Although markets for our lumber
products, especially for our southern lumber, remained depressed
throughout the fourth quarter of 2006, we did experience some
improvement in pricing near the end of the quarter," noted Michael J.
Covey, Potlatch chairman, president and chief executive officer. Due
to the poor lumber markets in the South, the company's Warren,
Arkansas, lumber mill took temporary downtime during the fourth
quarter of 2006. Income from the company's plywood operation was lower
in the fourth quarter of 2006 due primarily to decreases in average
selling prices compared to the third quarter of 2006 and the fourth
quarter of 2005.

    Pulp and Paperboard

    For the fourth quarter of 2006, the Pulp and Paperboard segment
reported operating income of $7.0 million, versus income of $14.3
million in the third quarter and a loss of $4.3 million for the fourth
quarter of 2005. "Markets for our pulp and paperboard products
remained strong throughout the fourth quarter, and both pricing and
shipments for our paperboard were higher compared to the third quarter
and 2005's fourth quarter," Covey noted. "Unfortunately, very high
wood fiber costs for our Lewiston, Idaho, pulp and paperboard
operation had a significant unfavorable effect on fourth quarter 2006
earnings compared to the two comparable periods," Covey added. The
high wood fiber costs were due largely to very high chip prices
resulting mainly from sawmill curtailments in the West.

    Consumer Products

    The Consumer Products segment reported operating income of $7.2
million for the fourth quarter of 2006, compared with operating income
of $6.2 million and $7.4 million reported for the third quarter of
2006 and the fourth quarter of 2005, respectively. Compared to the
third quarter, the higher income for the fourth quarter of 2006 was
primarily due to lower freight, energy and maintenance costs, which
were partially offset by decreased shipments and higher pulp costs.
The slightly lower income for the fourth quarter of 2006 compared to
the fourth quarter of 2005 was due largely to significantly higher
pulp costs, combined with higher freight and packaging costs. These
unfavorable comparisons were mostly offset by a 22% increase in
shipments.

    Other Items

    Excluding the income tax adjustment of $3.9 million primarily
related to the transfer of assets from the REIT to the company's
taxable REIT subsidiary in the fourth quarter of 2006, the company
recorded an income tax provision of $12.4 million for the fourth
quarter of 2006. The income tax provision was due primarily to pre-tax
income for the company's taxable REIT subsidiary.

    Outlook

    In the fourth quarter of 2006, Potlatch completed its initial
assessment of all of its land for alternative values. "As a result of
the initial assessment of our lands, we identified 250,000 to 300,000
acres, or 17% to 20% of our total land holdings, as having values that
are potentially greater than for timberland," Covey said. "Sales of
these lands are expected to occur within the next ten years, with the
goal of utilizing Internal Revenue code section 1031 like-kind
exchange transactions for tax efficiency, thus maximizing cash flows,"
he added. The company expects to sell 15,000 to 20,000 acres in 2007.

    In December 2006, the company announced an agreement to acquire
approximately 76,000 acres of high-value forestland in Wisconsin for
$64.5 million. The transaction was completed in January. The company
plans to match this purchase with sales of like-kind properties that
have recently closed and those that may occur in the first half of
2007 in our 1031 exchange program and thus not be subject to
built-in-gains taxes on those sales.

    "The company expects overall timber harvest levels and revenue to
increase in 2007 due to an increased harvest in Arkansas and the
acquisition of the Wisconsin timberland," Covey added. "Harvest levels
in Arkansas were deferred in 2006 due to unfavorable market
conditions. We also expect results for 2007 to be favorably affected
by mix improvements for our consumer tissue products. For our Idaho
pulp and paperboard operation, we have seen some moderation of the
acute wood chip and residual shortage that drove wood fiber prices
significantly higher in 2006's fourth quarter, and we are cautiously
optimistic that this situation will continue to improve as we move
into the Spring period. Markets for paperboard are expected to remain
strong throughout the first quarter of 2007, while wood products
markets are expected to remain weak early in 2007, as high inventories
of unsold new homes continue to impact the level of new home
construction."
