New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Recent Accounting Pronouncements	NOTE 2. RECENT ACCOUNTING PRONOUNCEMENTS New Accounting Standards Recently Adopted In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-02, Leases (Topic 842) We adopted ASU 2016-02, along with subsequent amendments, on January 1, 2019 and used the effective date as our date of initial application. Consequently, financial information will not be updated, and the disclosures required under the new standard will not be provided, for dates and periods before January 1, 2019. The new standard provides several optional practical expedients in transition and for an entity’s ongoing accounting. We elected the following practical expedients as part of our adoption of the standard: • to not reassess whether any expired or existing contracts are or contain leases; • to not reassess the lease classification for any expired or existing leases; • to not reassess initial direct costs for any existing leases; • to apply the short-term lease recognition exemption for all leases that qualify; • to not separate non-lease components from lease components; and • to apply the land easement practical expedient for transition of all existing land easements.

Deltic owned approximately 530,000 acres of timberland, operated two sawmills, a medium density fiberboard facility (MDF) and was engaged in real estate development primarily in Arkansas. The acquisition of total assets of $1.4 billion was a noncash investing and financing activity comprised of $1.1 billion in equity consideration transferred to Deltic shareholders and $0.3 billion of liabilities assumed. We expensed $1.0 million and $20.3 million of merger-related costs during the three and six months ended June 30, 2018, respectively. Total merger-related costs consisted of: • $10.6 million of merger-related costs for professional fees such as investment banker fees, legal, accounting and appraisal services; and • $9.7 million of restructuring costs primarily for termination benefits, which included accelerated share-based payment costs, for qualifying terminations. These costs are included in Deltic merger-related costs in our Condensed Consolidated Statements of Income .

Discontinued Operations And Disposal Groups [Abstract]
Sale of Deltic MDF Facility	NOTE 4. SALE OF DELTIC MDF FACILITY On December 20, 2018, we entered into an Asset Purchase and Sale Agreement (the Agreement) with Roseburg Forest Products Co. to sell the Deltic MDF facility for $92.0 million, consisting of $63.0 million in cash and assumption of $29.0 million of revenue bonds. The purchase price was subject to post-closing adjustments for certain changes in working capital as defined in the Agreement. The transaction closed on February 12, 2019 resulting in a $9.2 million pre-tax gain on sale. Cash proceeds received after working capital adjustments, closing costs and other expenses were approximately $58.8 million. A portion of the purchase price is escrowed pending satisfaction of certain covenants as outlined in the Agreement. In addition, we had a carryover tax basis in the facility from the Deltic merger, and as a result, we recorded a reduction to deferred tax liabilities and increase to income taxes payable of $15.8 million at the date of sale. At December 31, 2018, the assets and liabilities to be disposed met the criteria to be classified as held for sale and were reflected as such at their carrying value.

These contract liabilities are recognized over the term of the contracts, which is typically twelve months or less, except membership initiation fees at the Chenal Country Club which typically are recognized up to 10 years. Other contract asset and liability balances, such as prepayments, are immaterial. For real estate sales, we typically receive the entire consideration in cash at closing. The following table represents our revenues by major product.

Segment Reporting [Abstract]
Segment Information	NOTE 6. SEGMENT INFORMATION During the second quarter of 2019, we changed the name of our Resource segment to Timberlands. There were no changes in the segment’s business activities, components or information provided to our chief operating decision makers as a result of the change. Our businesses are organized into three reportable operating segments: Timberlands, Wood Products and Real Estate. Management activities in the Timberlands segment include planting and harvesting trees and building and maintaining roads. The Timberlands segment also generates revenues from non-timber resources such as hunting leases, recreation permits and leases, mineral rights contracts, oil and gas royalties, biomass production and carbon sequestration. The Wood Products segment manufactures and markets lumber and plywood. The business of our Real Estate segment includes the sale of land holdings deemed non-strategic or identified as having higher and better use alternatives. The Real Estate segment also engages in master planned communities, development activities and includes the Chenal Country Club. The reportable segments follow the same accounting policies used for our Condensed Consolidated Financial Statements nventories not valued under LIFO are recorded at the lower of average cost or net realizable value. Management primarily evaluates the performance of its segments and allocates resources to them based upon Adjusted EBITDDA. EBITDDA is calculated as net income (loss) before interest expense, income taxes, basis of real estate sold, depreciation, depletion and amortization. Adjusted EBITDDA further excludes certain specific items that are considered to hinder comparison of the performance of our businesses either year-on-year or with other businesses. Our calculation of Adjusted EBITDDA may not be comparable to that reported by other companies. The following table summarizes information on revenues, intersegment eliminations, Adjusted EBITDDA, depreciation, depletion and amortization, basis of real estate sold and total assets for each of the company’s reportable segments and includes a reconciliation of Total Adjusted EBITDDA to income before income taxes. Corporate information is included to reconcile segment data to the Condensed Consolidated Financial Statements .

Earnings Per Share [Abstract]
Earnings per Share	NOTE 7. EARNINGS PER SHARE The following table reconciles the number of shares used in calculating basic and diluted earnings per share: Three Months Ended June 30, Six Months Ended June 30, (in thousands, except per share amounts) 2019 2018 2019 2018 Net income $ 17,137 $ 46,148 $ 23,697 $ 60,745 Basic weighted-average shares outstanding 67,664 62,980 67,774 56,739 Incremental shares due to: Performance shares 26 303 21 299 Restricted stock units 23 33 71 90 Diluted weighted-average shares outstanding 67,713 63,316 67,866 57,128 Basic net income per share $ 0.25 $ 0.73 $ 0.35 $ 1.07 Diluted net income per share $ 0.25 $ 0.73 $ 0.35 $ 1.06 For stock-based awards, the dilutive effect is calculated using the treasury stock method. Under this method, the dilutive effect is computed as if the awards were exercised at the beginning of the period (or at time of issuance, if later) and assumes the related proceeds were used to repurchase common stock at the average market price during the period. Related proceeds include future compensation cost associated with the stock award. For the three and six months ended June 30, 2019, there were approximately 95,000 and 71,000 stock-based awards that were excluded from the calculation of diluted earnings per share because they were anti-dilutive. For the three and six months ended June 30, 2018, there were approximately 70,000 and 52,000 stock-based awards that were excluded from the calculation of diluted earnings per share because they were anti-dilutive. Anti-dilutive stock-based awards could be dilutive in future periods. Share Issuances Related to the Deltic Merger In February 2018 we issued 22.0 million shares in connection with the Deltic merger. Further, on August 30, 2018, the board of directors approved a special distribution of $222.0 million, or approximately $3.54 per share. The special distribution amount equaled our determination of the accumulated earnings and profits of Deltic as of the merger date and was distributed in order to maintain the company’s qualification as a REIT for U.S. federal income tax purposes. The special distribution 4.8 million shares of our common stock and distribution of $44.4 million in cash. Note 3: Merger with Deltic Share Repurchase Program On August 30, 2018, our board of directors authorized management to repurchase up to $100.0 million of common stock with no time limit set for the repurchase (the 2018 Repurchase Program). We repurchased 0.4 million shares of common stock (at a total consideration of $15.0 million) and 0.7 million shares of common stock (at a total consideration of $25.2 million), respectively, during the three and six months ended June 30, 2019 under the 2018 Repurchase Program. All common stock purchases under the 2018 Repurchase Programs were made in open-market transactions. No shares were repurchased during the three and six months ended June 30, 2018. At June 3 0 , 2019 , we had remaining authorization of $ 74.8 million for future stock repurchases under the 2018 Repurchase Program. We record share repurchases upon trade date as opposed to the settlement date when cash is disbursed. We record a liability to account for repurchases that have not been cash settled. There were no unsettled repurchases as of June 30, 2019. We retire shares upon repurchase. Any excess repurchase price over par is recorded in accumulated deficit.

Debt Disclosure [Abstract]
Debt	NOTE 9. DEBT In January 2019, we refinanced $150.0 million of 7.50% senior notes (Senior Notes) due in 2019 with a $150.0 million term loan that will mature in 2029. The new term loan carries a variable interest rate of one-month LIBOR plus 1.85%. We paid $0.5 million of lender fees on the new term loan. Concurrent with the new term loan, we entered into a $150.0 million interest rate swap to fix the rate at 4.56%. Upon the refinancing, we redeemed and paid all outstanding Senior Notes, including a redemption premium of $4.9 million which is included in the loss on extinguishment of debt in our Condensed Consolidated Statements of Income As part of the Deltic merger, we assumed the obligations relating to the letter of credit supporting Deltic’s $29.0 million Union County, Arkansas Taxable Industrial Revenue Bonds 1998 Series due October 1, 2027 associated with the Deltic MDF facility. As of December 31, 2018, the bonds were classified as held for sale as part of the sale of the Deltic MDF facility and excluded from long-term debt. As part of the sale of the MDF facility, the bonds were assumed by the buyer and the letter of credit was terminated. See Note 4: Sale of Deltic MDF Facility . As of June 30, 2019, we were in compliance with all debt and credit agreement covenants and approximately $1.0 million of our $380.0 million credit facility was utilized by outstanding letters of credit.

Derivative Instrument Detail [Abstract]
Derivative Instruments	NOTE 10. 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. 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. As of June 30, 2019, we have five interest rate swaps associated with $357.5 million of term loan debt. The cash flow hedges convert variable rates ranging from three-month and one-month LIBOR plus 1.85% to 2.15%, to fixed rates ranging from 3.88% to 4.82%. Our cash flow hedges are expected to be highly effective in achieving offsetting cash flows attributable to the hedged interest rate risk through the term of the hedge. At June 30, 2019, the amount of net losses expected to be reclassified into earnings in the next 12 months is approximately $3.0 million. The following table presents the gross fair values of derivative instruments on our Condensed Consolidated Balance Sheets Asset Derivatives Liability Derivatives (in thousands) Location June 30, 2019 December 31, 2018 Location June 30, 2019 December 31, 2018 Derivatives designated in cash flow hedging relationships: Interest rate contracts Other assets, non-current $ 113 $ 1,510 Other long-term obligations $ 21,333 $ 2,888 The following table details the effect of derivatives on our Condensed Consolidated Statements of Income Three Months Ended June 30, Six Months Ended June 30, (in thousands) Location 2019 2018 2019 2018 Derivatives designated in fair value hedging relationships: Interest rate contracts Realized loss on interest rate contracts 1 Interest expense $ — $ (50 ) $ (18 ) $ (86 ) Loss on hedged debt basis adjustment included in debt extinguishment — — (165 ) — $ — $ (50 ) $ (183 ) $ (86 ) Derivatives designated in cash flow hedging relationships: Interest rate contracts (Loss) income recognized in other comprehensive income, net of tax $ (10,598 ) $ 1,056 $ (19,192 ) $ 64 Loss reclassified from accumulated other comprehensive income 1 Interest expense $ (181 ) $ (193 ) $ (262 ) $ (195 ) Interest expense, net $ 7,882 $ 9,356 $ 13,346 $ 15,016 1 Realized gain (loss) on hedging instruments consist of net cash settlements and interest accruals on interest rate swaps during the periods.

The fair value of interest rate swaps are determined using a 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 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 company owned life insurance is based on the amount at which it could be redeemed and, accordingly, approximates fair value. We believe that our other financial instruments, including cash and cash equivalents, receivables and payables have net carrying values that approximate their fair values with only insignificant differences. This is primarily due to the short-term nature of these instruments and the allowance for doubtful accounts.

Share Based Compensation [Abstract]
Equity-Based Compensation	NOTE 12. EQUITY-BASED COMPENSATION On May 6, 2019 (the Effective Date) the stockholders approved our 2019 Long-Term Incentive Plan (the 2019 Plan). The total amount of PotlatchDeltic common stock authorized for issuance under the 2019 Plan includes, in addition to 1.2 million new shares approved by our stockholders: (i) the total number of shares available for future awards under the Potlatch Corporation 2014 Long-Term Incentive Plan and its predecessor plans (the Prior Plans) as of the Effective Date and (ii) the number of undelivered shares subject to outstanding awards under the Prior Plans that will become available for future issuance as provided for under the 2019 Plan. At June 30, 2019, approximately 1.5 million shares are available for future use under our long-term incentive plans. Share-based compensation activity during the six months ended June 30, 2019 included the following: (Shares in thousands) Granted Vested Forfeited Performance Share Awards (PSAs) 142 — 5 Restricted Stock Units (RSUs) 74 17 2 A total of 0.3 million shares of common stock were issued during the six months ended June 30, 2019 as a result of RSU and PSA vesting during 2018 and 2019. The following table details equity-based compensation expense and the related income tax benefit. Three Months Ended June 30, Six Months Ended June 30, (in thousands) 2019 2018 2019 2018 Equity-based compensation expense: Performance share awards $ 1,187 $ 1,074 $ 2,231 $ 2,010 Restricted stock units 629 454 1,187 934 Deferred compensation stock equivalent units expense 15 53 31 181 Accelerated share-based termination benefits in connection with the merger — 86 — 1,764 Total equity-based compensation expense $ 1,831 $ 1,667 $ 3,449 $ 4,889 Total tax benefit recognized for equity-based expense $ 83 $ 73 $ 155 $ 184 Performance Share Awards PSAs granted under the stock incentive plans have a three-year performance period and shares are issued at the end of the period if the performance measures are met. The performance measures are based on the percentile ranking of our total shareholder return relative to the total shareholder return performance of both a selected peer group of companies and a larger group of indexed companies over the three-year performance period. The number of shares actually issued, as a percentage of the amount subject to the PSA, could range from 0% to 200%. PSAs granted under our stock incentive plans do not have voting rights unless and until shares are issued upon settlement. If shares are issued at the end of the three-year performance measurement period, the recipients will receive dividend equivalents in the form of additional shares at the time of payment equal to the dividends that would have been paid on the shares earned had the recipients owned the shares during the three-year period. Therefore, the shares are not considered participating securities. The fair value of performance shares granted in 2019 was $37.87 per share. The following table presents the key inputs used in the Monte Carlo simulation to calculate the fair value of the performance share awards in 2019: Stock price as of valuation date $ 35.01 Risk-free rate 2.47 % Expected volatility 25.15 % Expected dividend yield (assuming full reinvestment) — Expected term (years) 3.00 Restricted Stock Units RSU awards accrue dividend equivalents based on dividends paid during the RSU vesting period. The dividend equivalents will be converted into additional RSUs that will vest in the same manner as the underlying RSUs to which they relate. Therefore, the shares are not considered participating securities. The terms of the awards state that the RSUs will vest in a given time period of one to three years and the terms of certain awards follow a vesting schedule within the given time period. The fair value of RSUs granted equaled our common share price on the date of grant. The weighted average fair value of all RSUs granted during the six months ended June 30, 2019 was $36.15.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 13. 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. In addition, we had carryover tax basis in the MDF facility from the Deltic merger and as a result, during the six months ended June 30, 2019, we recorded a reduction to deferred tax liabilities and increase to income taxes payable of $15.8 million at the date of sale. See Note 4: Sale of Deltic MDF Facility

Leases [Abstract]
Leases	NOTE 14. LEASES We lease certain equipment, office space and land. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate, which is derived from information available at the lease commencement date, in determining the present value of lease payments. We consider our recent debt issuances as well as publicly available data for instruments with similar characteristics when calculating our incremental borrowing rates. Most leases include one or more options to renew, with renewal terms that can extend the lease term between one to five years. The exercise of lease renewal options is at our sole discretion. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. Finance leases at June 30, 2019 were insignificant. For certain equipment leases, we apply a portfolio approach to effectively account for the operating lease ROU assets and liabilities. For certain equipment leases, such as vehicles, we account for the lease and non-lease components as a single lease component. Certain leases also include options to purchase the leased equipment. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Certain of our lease agreements include rental payments adjusted periodically for inflation. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants and we do not have any significant sublease income.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Standards Recently Adopted In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-02, Leases (Topic 842) We adopted ASU 2016-02, along with subsequent amendments, on January 1, 2019 and used the effective date as our date of initial application. Consequently, financial information will not be updated, and the disclosures required under the new standard will not be provided, for dates and periods before January 1, 2019. The new standard provides several optional practical expedients in transition and for an entity’s ongoing accounting. We elected the following practical expedients as part of our adoption of the standard: • to not reassess whether any expired or existing contracts are or contain leases; • to not reassess the lease classification for any expired or existing leases; • to not reassess initial direct costs for any existing leases; • to apply the short-term lease recognition exemption for all leases that qualify; • to not separate non-lease components from lease components; and • to apply the land easement practical expedient for transition of all existing land easements. Condensed Consolidated Balance Sheet Condensed Consolidated Statement of Income and our Condensed Consolidated Statement of Cash Flows . See Note 1 4 : Leases for our expanded disclosures. New Accounting Standards Being Evaluated In August 2018, the FASB issued ASU No. 2018-15 Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract In August 2018, the FASB issued ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Topic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement
