Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS
	In January 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-01, Financial Instruments, which clarifies the scope of disclosures about offsetting assets and liabilities. This pronouncement limits the scope of instruments subject to ASU 2011-11's offsetting disclosures to derivatives, repurchase and reverse repurchase agreements, and securities borrowing and lending agreements subject to master netting arrangements or similar agreements. ASU No. 2013-01 was effective for fiscal years and interim periods beginning on or after January 1, 2013, and was adopted in the first quarter of 2013. The accounting guidance only impacts disclosure requirements and its adoption did not have a material impact on our consolidated financial statements. Refer to Note 9, Financial Instruments, for additional information.
	In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income, which expands disclosures for items reclassified out of accumulated other comprehensive income (AOCI). For items reclassified out of AOCI and into net income in their entirety, disclosure of the effect of the reclassification on each affected net income line item on the face of the statement of income or in the footnotes is required. For AOCI reclassification items that are not reclassified in their entirety into net income, a cross reference to other required U.S. GAAP disclosures is required. ASU No. 2013-02 was effective for reporting periods beginning after December 15, 2012, and was adopted in the first quarter of 2013. The accounting guidance only impacts disclosure requirements and its adoption did not have a material impact on our consolidated financial statements. Refer to Note 7, Pension Plans and Other Postretirement Employee Benefits, for the new disclosure.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES
	As a real estate investment trust (REIT), we generally are not subject to federal and state corporate income taxes on income of the REIT that we distribute to our shareholders. We are, however, subject to corporate taxes on built-in gains (the excess of fair market value over tax basis on January 1, 2006) on sales of real property held by the REIT during the first ten years following the REIT conversion. The sale of standing timber is not subject to built-in gains tax. The Small Business Jobs Act of 2010 modified the built-in gains provisions to exempt sales of real properties in 2011, if five years of the recognition period had elapsed before January 1, 2011. The American Taxpayer Relief Act of 2012 extended the reduced five-year holding period for sales occurring in 2012 and 2013. Accordingly, the built-in gains tax does not apply to sales of real property that occur in 2011, 2012 and 2013.
	We are required to pay federal and state corporate income taxes on earnings of our taxable REIT subsidiaries (TRS) operations, principally comprised of our wood products manufacturing operations and certain real estate investments held for development and resale.
	For the quarters ended September 30, 2013 and 2012, we recorded income tax provisions of $3.2 million and $3.9 million, respectively, primarily due to pre-tax income of the TRS. For the nine months ended September 30, 2013 and 2012, we recorded income tax provisions of $12.5 million and $10.6 million, respectively, primarily due to pre-tax income of the TRS.

	FAIR VALUE HEDGES OF INTEREST RATE RISK
	As of September 30, 2013, we had six separate interest rate swaps with notional amounts totaling $46.75 million. The swaps convert interest payments with fixed rates to variable rates of 3-month LIBOR plus a spread.
	NON-DESIGNATED LUMBER SWAPS
	We participated in one commodity swap contract that cash settled in the first quarter of 2012 and two that cash settled in the second quarter of 2012. Changes in the fair value of derivatives not designated in hedging relationships were recorded directly in net income. As of September 30, 2013 there were no outstanding lumber swap contracts.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES
	In January 2007, the Environmental Protection Agency (EPA) notified us that we are a potentially responsible party under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA) and the Clean Water Act for cleanup of a site known as Avery Landing in northern Idaho. We own a portion of the land at the Avery Landing site, which we acquired in 1980 from the Milwaukee Railroad. The land we own at the site and adjacent properties were contaminated with petroleum as a result of the Milwaukee Railroad's operations at the site prior to 1980. We entered into a consent order with the EPA in August 2008 to conduct an Engineering Evaluation/Cost Analysis (EE/CA) study to determine the best means of addressing the contamination at the site. In January 2010, we submitted our draft EE/CA report to the EPA outlining various alternatives for addressing the contamination at the entire site. Ultimately, the EPA published a draft EE/CA report on January 26, 2011 for public comment. The public comment period closed March 11, 2011, and on July 5, 2011, the EPA issued an Action Memorandum for the Avery Landing Site selecting contaminant extraction and off-site disposal as the remedial alternative. On May 23, 2012, we signed a consent order with the EPA pursuant to which we agreed to provide $1.75 million in funding for EPA cleanup on a portion of our property (including the adjacent riverbank owned by the Idaho Department of Lands). On April 4, 2013, the EPA issued a unilateral administrative order requiring us to remediate the portion of the Avery Landing site that we own. During the first quarter of 2013, we increased our accrual by $0.75 million. We began work on the site in May 2013 and discovered more contaminant on our property than had been expected based upon previous testing, and accordingly, during the second quarter of 2013 we increased our expense by an additional $1.75 million. During the third quarter of 2013, we increased our accrual by approximately $1.0 million to reflect the final work completed on the site in September 2013.
	The following table details our Avery Landing environmental remediation charge and reserve balance for the quarters and nine months ended September 30:
		Quarter Ended					Nine Months Ended
		September 30,					September 30,

	Ending reserve balance	$	729		$	4,250	$	729		$	4,250
	Negotiations with the EPA continue regarding a final settlement and release, and we cannot predict at this time what additional costs, if any, that we may incur on this matter. We have reserved all of our rights to seek reimbursement for the costs of remediation from all parties potentially responsible.
