               Potlatch Reports Second Quarter Results

    SPOKANE, Wash.--(BUSINESS WIRE)--July 26, 2007--Potlatch
Corporation (NYSE:PCH) today reported financial results for the second
quarter ended June 30, 2007.

    Financial Highlights

        --  Second quarter earnings from continuing operations were
            $35.4 million, or $0.90 per diluted common share

        --  Earnings from continuing operations for the first half of
            2007 were $40.8 million, or $1.04 per diluted common share

        --  Cash provided by operating activities from continuing
            operations was $73.1 million for the six months ended June
            30, 2007

    "Log pricing during the second quarter remained strong despite a
persistent weakness in lumber pricing caused by the continued slump in
U.S. housing starts," said Michael J. Covey, chairman, president and
chief executive officer.

    "During the second quarter, Potlatch made significant progress
toward achieving its 2007 goal of selling 15,000-20,000 acres of
non-strategic land. The company sold nearly 7,500 acres of non-core
lands with revenue of $8.6 million. Although timing of real estate
closings is difficult to forecast, the market for rural recreation
property remains strong.

    "In addition, second quarter results were augmented by exceptional
results in the Pulp and Paperboard division, where we had record
production and strong pricing. Market prices for pulp are as strong as
they have been in the past 12 years.

    "Finally, sales for all of Potlatch's Forest Stewardship Council
(FSC) certified solid wood and paperboard products showed continued
growth during the quarter."

    Q2 2007 Financial Summary

        --  Earnings from continuing operations were $35.4 million, or
            $0.90 per diluted common share, compared to $8.2 million
            or $0.21 per diluted common share for the second quarter
            2006. Second quarter 2007 results included a one-time
            payment of $1.4 million for retroactive pay associated
            with the settlement of the union contracts for the
            company's pulp and paperboard and consumer products
            operations in Lewiston.

        --  Net earnings for the second quarter 2007 were $34.0
            million, or $0.87 per diluted common share, compared to
            $2.4 million, or $0.06 per diluted common share, for the
            second quarter 2006. During the second quarter 2007, the
            company completed the sale of its hybrid poplar tree farm
            in Boardman, Oregon, to a private-equity tree farm
            investment fund for approximately $65 million in cash.
            Results for the hybrid poplar tree farm, which are
            included in net earnings and are classified as
            discontinued operations in the Statements of Operations
            and Comprehensive Income, were a net loss of $1.4 million
            for the second quarter 2007, compared to a net loss of
            $5.8 million in the second quarter 2006.

    First Half 2007 Financial Summary

        --  Earnings from continuing operations were $40.8 million, or
            $1.04 per diluted common share, compared to $77.6 million
            or $2.26 per diluted common share for the first half of
            last year. Results from continuing operations for the
            first half of 2006 included a net tax benefit of $51.2
            million related to the company's conversion to a real
            estate investment trust.

        --  Cash provided by operating activities from continuing
            operations for the first half of 2007 was $73.1 million,
            compared to $108.6 million for the same period in 2006.

        --  Net earnings were $4.2 million, or $0.11 per diluted
            common share, compared to net earnings of $68.1 million,
            or $1.98 per diluted common share, for the first half of
            2006. First half results included an after-tax loss on
            disposal of $33.0 million for the sale of the company's
            hybrid poplar tree farm in 2007 and after-tax operating
            losses for the tree farm of $3.7 million and $9.4 million
            for 2007 and 2006, respectively.

    Second Quarter 2007 Business Performance

    Resource

        --  Operating income for the segment was $19.9 million,
            compared to $16.1 million earned in the second quarter
            2006.

        --  Potlatch capitalized on improving markets in the southern
            region and sold more volume compared to 2006, when harvest
            levels were partially curtailed due to poor market
            conditions.

        - Fee harvest increased 116 percent in the quarter compared to
        the second quarter 2006.

        - Prices rose 2.5 percent in the southern region compared to
        first quarter 2007 and 7.7 percent compared to the second
        quarter 2006.

        --  Harvest levels in the northern region were up overall
            compared to the same period last year. Increased harvest
            levels in Idaho were the primary contributor.

        - Fee harvest declined 9.2 percent from the first quarter
        2007, primarily due to seasonal logging curtailments; however,
        harvest levels were up 9.9 percent compared to the second
        quarter 2006.

        - Prices rose 13 percent in the northern region compared to
        the first quarter 2007 but were down 10 percent compared to
        the second quarter 2006. Species variability and general price
        erosion in Minnesota contributed to the year-over-year
        unfavorable variance.

    Real Estate

    (formerly known as Land Sales and Development)

        --  Operating income for the segment was $7.4 million,
            compared with $1.5 million for the second quarter 2006.
            The improved results were attributable primarily to the
            sale of non-core lands. These non-strategic lands require
            less market preparation than our higher and better use
            (HBU) lands, and therefore are more readily available for
            sale, but also carry lower average retail values per acre
            than our expected HBU sales will bring.

        --  With establishment of the real estate infrastructure
            during the first quarter of 2007, Potlatch was able to
            successfully complete the sale of 7,472 acres of non-core
            land primarily in Minnesota and Idaho at an average price
            of $1,146 per acre.

        --  During the second quarter, Potlatch deferred approximately
            $20 million in built-in-gain taxes from REIT land sales by
            matching land sales with acquisitions such as our
            76,000-acre Wisconsin purchase.

    As noted, progress continues on Potlatch's intensive land value
stratification process, which was announced on December 11, 2006.
Through the stratification process, the company identified
250,000-300,000 acres that are non-strategic to its core forestland
operations that it expects to sell over the next 10 years.

    Wood Products

        --  Operating income for the segment was $6.4 million,
            compared to $3.6 million for the second quarter 2006.

    Lumber results continued to be buoyed by sales of inland red cedar
even though cedar logs comprised a smaller portion of lumber
production than in previous quarters, due primarily to seasonality.
Even in a difficult pricing environment, Potlatch continues to
generate positive cash flow in the Wood Products segment. The Potlatch
FSC lumber business is growing rapidly from year to year, as evidenced
by second quarter FSC sales and volume figures increasing three-fold
over last year's second quarter.

    Pulp and Paperboard

        --  Operating income for the segment was $17.0 million,
            compared to an operating loss of $5.4 million for the
            second quarter 2006.

        --  Shipments increased 5 percent compared to the second
            quarter 2006 as both mills ran very well.

        --  Pulp prices are as strong as they have been at any time in
            the last 12 years.

        --  Market prices for paperboard products were 7 percent
            higher in the quarter compared to the second quarter 2006.
            Furthermore, the results were augmented by the sale of
            increased volumes of higher quality products to an
            expanded customer mix.

    The division's success in commercial markets is enhanced by
Potlatch's ability to provide paperboard that is FSC certified.
Customers recognize that this certification means that the fiber being
used in producing Potlatch's products is sustainable in nature, the
methods used to harvest are sensitive to the environment, and that is
of value to them.

    Consumer Products (or "Tissue")

        --  Operating income for the segment was $4.1 million,
            compared to $7.0 million for the same period last year.

    Pulp prices increased by 23 percent with a $5.7 million negative
cost impact for the quarter compared to the same period last year, but
the segment has not seen a corresponding increase in retail pricing
for tissue. Thus, margins are being squeezed. Offsetting this are
efforts to reduce freight and increase converting capacity that has
allowed the segment to shift its sales mix away from un-converted,
bulk parent rolls to finished products.

    Other Items

    In the second quarter of 2007, the company recorded an income tax
provision of $6.3 million related to continuing operations. The income
tax provision was due to pre-tax income for the company's taxable REIT
subsidiary.

    Dividend Distribution

    During the second quarter, Potlatch paid a regular quarterly
distribution on the company's common stock of $0.49 per share.

    Outlook

    "Our performance in the first half of this year reinforces our
conviction that we have the right strategy for Potlatch," remarked Mr.
Covey. "Regardless of the business environment, we remain focused on
our long-term goals of concentrating on our timberlands business and
capitalizing on our real estate segment.

    "We expect log pricing to remain firm in all regions. Lumber
prices have increased by approximately 7 percent since the fourth
quarter of 2006. We anticipate additional downward pressure on framing
lumber in the third and fourth quarter, and anticipate cedar to remain
firm. In addition, we anticipate paperboard markets to remain strong
throughout the second half of the year, and we believe Potlatch is
well positioned to capitalize on this strength with a continuation of
exceptional production at both the Arkansas and Idaho paper mills. We
expect tissue margins to remain under pressure due to high pulp costs
anticipated for the balance of 2007."

    Mr. Covey concluded, "We believe Potlatch is on target to achieve
its 2007 goal of 15,000-20,000 acres in land sales by the end of this
year, as interest and demand for rural recreational land property
remains strong."
