BASIS OF PRESENTATION For purposes of this report, any reference to “Potlatch,” “the company,” “we,” “us,” and “our” means Potlatch Corporation and all of its wholly-owned subsidiaries, except where the context indicates otherwise. The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission pertaining to interim financial statements; certain disclosures normally provided in accordance with generally accepted accounting principles in the United States have been omitted. This Quarterly Report on Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2016, as filed with the Securities and Exchange Commission on February 17, 2017. We believe that all adjustments necessary for a fair statement of the results of such interim periods have been included and all such adjustments are of a normal recurring nature. Certain 2016 amounts on the Condensed Consolidated Statements of Cash Flows within Cash Flows from Operating Activities have been reclassified to conform to the 2017 presentation.

The company purchased the property in 2007 and 2008 for the purpose of growing and harvesting timber and selling rural recreation parcels. The sale freed up capital without having to wait for the rural recreation real estate market in central Idaho to recover. We recorded a loss of $48.5 million before taxes in our Real Estate segment in the second quarter of 2016. Historical earnings generated by the property were positive, but not material.

Derivative Instrument Detail [Abstract]
Derivative Instruments	NOTE 5. DERIVATIVE INSTRUMENTS From time to time, we enter into derivative financial instruments to manage certain cash flow and fair value risks. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset or liability to a particular risk, such as interest rate risk, are considered fair value hedges. We have five fair value interest rate swaps to convert interest payments on fixed-rate debt to variable-rate 3-month LIBOR plus a spread. Derivatives designated and qualifying as a hedge of the exposure to variability in the cash flows of a specific asset or liability that is attributable to a particular risk, such as interest rate risk, are considered cash flow hedges. We have one interest rate swap to convert variable-rate debt, comprised of 3-month LIBOR plus a spread, to fixed-rate debt. Our cash flow hedge is expected to be highly effective in achieving offsetting cash flows attributable to the hedged interest rate risk through the term of the hedge. Therefore, changes in the fair value of the interest rate swap are recorded as a component of other comprehensive income and will be recognized in earnings when the hedged interest rate affects earnings. The amounts paid or received on this interest rate hedge will be recognized as adjustments to interest expense. As of June 30, 2017, the amount of net losses expected to be reclassified into earnings in the next 12 months is $0.1 million. Derivatives not designated as hedges are not speculative and are used to manage our exposure to interest rate movements, commodity price movements or other identified risks, but do not meet the strict hedge accounting requirements. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly into income. In April 2017, we entered into a lumber price swap to fix the price on a total of 36 million board feet (mmbf) of southern yellow pine with an effective date of July 1, 2017 and a termination date of December 31, 2017. Under the contract, cash settlement on 6 mmbf occurs monthly.

For cash and cash equivalents and revolving line of credit borrowings, the carrying amount approximates fair value due to the short-term nature of these financial instruments. The fair value of interest rate and lumber price swaps are determined using discounted cash flow analysis on the expected cash flows of each derivative. The analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate and commodity price forward curves. The fair value of our long-term debt is estimated based upon quoted market prices for similar debt issues or estimated based on average market prices for comparable debt when there is no quoted market price. The contract value of our COLI, the amount at which it could be redeemed, is used to estimate fair value because market prices are not readily available.

Equity-Based Compensation	NOTE 9. EQUITY-BASED COMPENSATION As of June 30, 2017, we had two stock incentive plans under which performance shares, restricted stock units (RSUs) and deferred compensation stock equivalent units were outstanding. These plans have received shareholder approval. We were originally authorized to issue up to 1.6 million shares and 1.0 million shares under our 2005 Stock Incentive Plan and 2014 Stock Incentive Plan, respectively. At June 30, 2017, approximately 1.0 million shares were authorized for future use. We issue new shares of common stock to settle performance shares, restricted stock units and deferred compensation stock equivalent units.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 10. 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 conduct certain activities through our taxable REIT subsidiaries (TRS), which are subject to corporate level federal and state income taxes. These taxable activities are principally comprised of our wood products manufacturing operations and certain real estate investments. Therefore, income tax expense or benefit is primarily due to income or loss of the TRS, as well as permanent book versus tax differences.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 11. 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. 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). The EPA cleanup was completed in October 2012. 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. Our remediation was completed in October 2013. In 2016, the EPA confirmed that Potlatch had completed the cleanup and subsequent monitoring required by the unilateral order. On September 25, 2015, the EPA sent us a letter asserting that the EPA and the Department of Transportation (the current owner of a portion of the adjacent property remediated by the EPA) (DOT) had incurred $9.8 million in unreimbursed response costs associated with the site and that we were liable for such costs. We executed a tolling agreement with the EPA and DOT suspending the statute of limitations on the claim until September 2016 in order to facilitate negotiations of a final settlement and release. In September, the parties agreed to extend the tolling agreement through October 6, 2016. The tolling agreement was further extended through February 22, 2017; in January 2017, Settlement negotiations continue. If settlement efforts prove to be unsuccessful, we believe we have meritorious defenses to this claim and we intend to defend ourselves vigorously. We accrued $0.2 million for this matter in the first quarter of 2016 and an additional $0.8 million for this matter in the second quarter of 2016. It is reasonably possible that our liability may exceed our accrual by up to approximately $2 million. We have reserved all of our rights to seek reimbursement for the costs of remediation from all parties potentially responsible.
