Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	NO TE 1. BASIS OF PRESENTATION General PotlatchDeltic Corporation and its subsidiaries (collectively referred to in this report as the company, us, we or our) is a leading timberland Real Estate Investment Trust (REIT) with operations in nine states. We are engaged in activities associated with timberland management, including the sale of timber, the management of nearly 2.2 million acres of timberlands and the purchase and sale of timberlands. We are also engaged in the manufacturing and sale of wood products and the development of real estate. Our timberlands, real estate development projects and all of our wood products facilities are located within the continental United States. The primary market for our products is the United States. We converted to a REIT effective January 1, 2006. Condensed Consolidated Financial Statements The accompanying unaudited Condensed Consolidated Financial Statements provide an overall view of our results and financial condition and reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods presented. Except as otherwise disclosed in these Notes to Condensed Consolidated Financial Statements , such adjustments are of a normal, recurring nature. Intercompany transactions and accounts have been eliminated in consolidation. The 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 accounting principles generally accepted in the United States (GAAP) 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, 2022, as filed with the Securities and Exchange Commission on February 16, 2023. Results of operations for interim periods should not be regarded as necessarily indicative of the results that may be expected for the full year. Increased Authorized Shares of Common Stock On May 1, 2023, the stockholders of the company approved an amendment (the “Amendment”) to the Company’s Third Restated Certificate of Incorporation (the “Charter”) to increase the number of authorized shares of the company’s common stock from 100 million to 200 million. The Amendment became effective upon the filing of the Certificate of Amendment to the Charter with the Secretary of State of the State of Delaware on May 1, 2023. Use of Estimates The preparation of our Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and requires judgments affecting the amounts reported in the financial statements and the accompanying notes. Actual results may differ materially from our estimates. Recent Accounting Standards From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board or other standard setting bodies and are adopted by the company as of the specified effective date. For the nine months ended September 30, 2023, there were no new accounting pronouncements that management believes materially affect the company’s present or future results of operations, overall financial condition, liquidity or disclosures.

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 and carbon sequestration. The Wood Products segment manufactures and sells lumber and plywood. The Real Estate segment includes the sale of land holdings deemed non-strategic or identified as having higher and better use alternatives, a master planned community development and a country club. Our Timberlands segment supplies our Wood Products segment with a portion of its wood fiber needs. These intersegment revenues are based on prevailing market prices and typically represent a sizable portion of the Timberlands segment’s total revenues. Our other segments generally do not generate intersegment revenues. These intercompany transactions are eliminated in consolidation. The reportable segments follow the same accounting policies used for our Condensed Consolidated Financial Statements , with the exception of the valuation of inventories, which are reported using the average cost method for purposes of reporting segment results. The following table presents our revenues by major product: Three Months Ended September 30, Nine Months Ended September 30, (in thousands) 2023 2022 2023 2022 Timberlands Northern region Sawlogs $ 48,538 $ 78,668 $ 138,685 $ 223,102 Pulpwood 330 582 1,102 1,561 Other 362 281 995 797 Total Northern revenues 49,230 79,531 140,782 225,460 Southern region Sawlogs 31,863 29,618 91,419 77,364 Pulpwood 17,503 17,694 48,641 41,542 Stumpage 7,057 4,028 20,438 9,494 Other 4,155 3,705 12,383 9,859 Total Southern revenues 60,578 55,045 172,881 138,259 Total Timberlands revenues 109,808 134,576 313,663 363,719 Wood Products Lumber 132,852 151,540 379,939 622,228 Residuals and Panels 32,256 41,891 105,633 133,578 Total Wood Products revenues 165,108 193,431 485,572 755,806 Real Estate Rural real estate 11,616 6,182 34,005 44,268 Development real estate 4,289 10,205 16,498 28,429 Other 3,247 2,621 9,576 7,112 Total Real Estate revenues 19,152 19,008 60,079 79,809 Total segment revenues 294,068 347,015 859,314 1,199,334 Intersegment Timberlands revenues 1 ( 28,559 ) ( 40,322 ) ( 89,736 ) ( 121,694 ) Other intersegment revenues — — ( 6 ) — Total consolidated revenues $ 265,509 $ 306,693 $ 769,572 $ 1,077,640 1 Intersegment revenues represent logs sold by our Timberlands segment to our Wood Products segment. Management uses Adjusted EBITDDA to evaluate the operating performance and effectiveness of operating strategies of our segments and allocation of resources to them. EBITDDA is calculated as net income 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 for each of the company’s reportable segments and includes a reconciliation of Total Adjusted EBITDDA to income before income taxes.

Earnings Per Share [Abstract]
Earnings per Share	NO TE 3. EARNINGS PER SHARE The following table reconciles the number of shares used in calculating basic and diluted earnings per share: Three Months Ended September 30, Nine Months Ended September 30, (in thousands) 2023 2022 2023 2022 Basic weighted-average shares outstanding 80,132 71,486 80,102 70,171 Incremental shares due to: Performance shares 182 111 137 104 Restricted stock units 65 35 40 33 Diluted weighted-average shares outstanding 80,379 71,632 80,279 70,308 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 nine months ended September 30, 2023, there were approximately 2,000 and 28,000 stock-based awards, respectively, that were excluded from the calculation of diluted earnings per share as they were anti-dilutive. For the three and nine months ended September 30, 2022, there were approximately 117,000 and 136,000 stock-based award shares, respectively, that were excluded from the calculation of diluted earnings per share as they were anti-dilutive. 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). During the three and nine months ended September 30, 2022, we repurchased 8,444 and 103,010 shares of our common stock (for total consideration of $ 0.4 million and $ 4.5 million), respectively, in open-market transactions under the 2018 Repurchase Program. On August 31, 2022, our board of directors authorized management to repurchase up to $ 200.0 million of our common stock with no set time limit for the repurchase (the 2022 Repurchase Program). Concurrently, the board of directors terminated the remaining repurchase authorization under the 2018 Repurchase Program. Shares under the 2022 Repurchase Program may be repurchased in open market transactions, including pursuant to a trading plan adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934 (the Trading Plan), or through privately negotiated transactions. The timing, manner, price and amount of repurchases will be determined according to, and subject to, the terms of the Trading Plan, and, subject to the terms of the Trading Plan, the 2022 Repurchase Program may be suspended, terminated or modified at any time for any reason. During the three and nine months ended September 30, 2023, we repurchased 282,988 and 291,749 shares of our common stock (for total consideration of $ 12.7 million and $ 13.1 million) respectively, in open-market transactions under the 2022 Repurchase Program. No shares were repurchased under the 2022 Repurchase Program during the nine months ended September 30, 2022. At September 30, 2023, we had remaining authorization of $ 136.9 million for future stock repurchases under the 2022 Repurchase Program. Transaction costs are not counted against authorized funds. 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. We retire shares upon repurchase. Any excess repurchase price over par is recorded in accumulated deficit.

There were no injuries or environmental issues from the fire. The damage was principally limited to the large log primary breakdown area of the mill. The new equipment has been installed and the large log line restarted in September 2022. We have adequate property damage and business interruption insurance, subject to a $ 2.0 million deductible. Insurance recoveries are recorded when deemed probable and reasonably estimable. In September 2023, we finalized our claim with the insurance carriers resulting in $ 89.4 million of total insurance recoveries, net of a $ 2.0 million deductible, for both the property damage and business interruption claims. During the three and nine months ended September 30, 2023, we recorded insurance recoveries of $ 16.3 million and $ 39.4 million, respectively, from the Ola sawmill claim, all of which was recognized as a gain on fire damage in the Condensed Consolidated Statements of Operations . During the three and nine months ended September 30, 2022, we recorded $ 24.9 million and $ 34.1 million, respectively, as gain on fire damage.

Debt Disclosure [Abstract]
Debt	NO TE 5. DEBT TERM LOANS At September 30, 2023, our total outstanding principal on our long-term debt of $ 1.0 billion included $ 971.0 million of term loans under our Second Amended and Restated Term Loan Agreement (Amended Term Loan Agreement) with our primary lender, which includes a $ 40 million term loan that we expect to refinance upon its maturity in December 2023 . Certain borrowings under the Amended Term Loan Agreement are at the one-month Secured Overnight Financing Rate ("SOFR")-indexed variable rates, plus a spread between 1.66 % and 2.30 %. We have entered into SOFR-indexed interest rate swaps to fix the interest rate on these variable rate term loans. See Note: 6 Derivative Instruments for additional information. CREDIT AGREEMENT On May 18, 2023, we entered into a First Amendment to the Third Amended and Restated Credit Agreement (Amended Credit Agreement). The Amended Credit Agreement provides for loans based on SOFR instead of the London Inter-Bank Offered Rate (“LIBOR”), provides us the option to borrow based on a daily SOFR or term SOFR basis, and provides mechanics relating to the transition from the use of SOFR to a replacement benchmark rate upon the occurrence of certain transition events. The Amended Credit Agreement provides for a $ 300.0 million revolving line of credit that matures February 14, 2027 . As provided in the Amended Credit Agreement, borrowing capacity may be increased by up to an additional $ 500.0 million. The r evolving line of credit also includes a sublimit of $ 75.0 million for the issuance of standby letters of credit and a sublimit of $ 25.0 million for swing line loans. Usage under either or both sub facilities reduces availability under the revolving line of credit. We may utilize borrowings under the Amended Credit Agreement to, among other things, refinance existing indebtedness and provide funding for working capital requirements, capital projects, acquisitions and other general corporate expenditures. At September 30, 2023, there were no borrowings under the revolving line of credit and approximately $ 0.7 million of our revolving line of credit was utilized for outstanding letters of credit. We were in compliance with all debt and credit agreement covenants at September 30, 2023.

Derivative Instruments

Derivative Instrument Detail [Abstract]
Derivative Instruments	NO TE 6. 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 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. All 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 hedges. At September 30, 2023, we have interest rate swaps associated with $ 721.0 million of SOFR-indexed term loan debt. These cash flow hedges convert variable rates ranging from one-month SOFR plus 1.66 % to 2.30 %, to fixed rates ranging from 2.19 % to 4.79 % before patronage credits from lenders. At September 30, 2023, we also have $ 250.0 million of forward-starting interest rate swaps designated as cash flow hedges for expected future debt refinances that require settlement on the stated maturity date. The gross fair values of derivative instruments at September 30, 2023 and December 31, 2022, were $ 166.3 million and $ 144.6 million, respectively, all of which were classified in Other assets, non-current on our Condensed Consolidated Balance Sheets . Derivative instruments that mature within one year, as a whole, are classified as current. The following table details the effect of derivatives on the Condensed Consolidated Statements of Operations and the Condensed Consolidated Statements of Comprehensive Income : Three Months Ended September 30, Nine Months Ended September 30, (in thousands) Location 2023 2022 2023 2022 Derivatives designated in cash flow hedging relationships: Interest rate contracts Income recognized in other comprehensive income (loss), net of tax $ 33,607 $ 32,900 $ 42,353 $ 115,408 Amounts reclassified from accumulated other comprehensive income (loss), net of tax 1 Interest expense, net $ 5,143 $ 175 $ 13,505 $ ( 3,122 ) Interest expense, net $ 7,971 $ 8,280 $ 15,783 $ 18,593 1 Realized gains and losses on interest rate contracts consist of realized net cash received or paid and interest accruals on the interest rate swaps during the periods in addition to amortization of amounts out of other comprehensive (loss) income related to certain terminated hedges and adjustments to interest expense resulting from amortization of inception value of certain off-market designated hedges. Net cash received or paid is included within Interest expense, net in the Condensed Consolidated Statements of Operations . At September 30, 2023, the amount of net gains expected to be reclassified into earnings in the next 12 months is approximately $ 20.9 million. However, this expected amount to be reclassified into earnings is subject to volatility as the ultimate amount recognized in earnings is based on the SOFR rates at the time of net swap cash payments.

Fair Value Measurements	NO TE 7. FAIR VALUE MEASUREMENTS The following table presents the estimated fair values of our financial instruments: September 30, 2023 December 31, 2022 (in thousands) Carrying Fair Carrying Fair Derivative assets related to interest rate swaps (Level 2) $ 166,256 $ 166,256 $ 144,583 $ 144,583 Long-term debt, including current portion (Level 2): Term loans $ ( 969,757 ) $ ( 962,843 ) $ ( 969,269 ) $ ( 961,632 ) Revenue bonds ( 65,735 ) ( 64,549 ) ( 65,735 ) ( 64,602 ) Total long-term debt 1 $ ( 1,035,492 ) $ ( 1,027,392 ) $ ( 1,035,004 ) $ ( 1,026,234 ) Company owned life insurance asset (COLI) (Level 3) $ 4,923 $ 4,923 $ 4,311 $ 4,311 1 The carrying amount of long-term debt includes principal and unamortized discounts. The fair value of interest rate swaps is determined using a discounted cash flow analysis, based on third-party sources, 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, restricted cash, 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.

Equity-Based Compensation	NO TE 8. EQUITY-BASED COMPENSATION We issue new shares of common stock to settle performance stock awards (PSAs), restricted stock units (RSUs) and deferred compensation stock equivalent units. At September 30, 2023, approximately 1.8 million shares were available for future use under our long-term incentive plans. Share-based compensation activity during the nine months ended September 30, 2023, included the following: Granted Vested Forfeited Performance Share Awards (PSAs) 106,342 — 28,177 Restricted Stock Units (RSUs) 127,079 17,225 12,727 Approximately 0.2 million shares of common stock were issued to employees during the nine months ended September 30, 2023 as a result of PSA and RSU vesting during 2022 and 2023. The following table details compensation expense and the related income tax benefit for company specific equity-based awards: Three Months Ended September 30, Nine Months Ended September 30, (in thousands) 2023 2022 2023 2022 Equity-based compensation expense: Performance share awards $ 1,483 $ 1,535 $ 3,623 $ 4,351 Restricted stock units 1,084 825 2,702 2,335 Deferred compensation stock equivalent units expense 49 49 147 147 Total equity-based compensation expense $ 2,616 $ 2,409 $ 6,472 $ 6,833 Total tax benefit recognized for equity-based expense $ 135 $ 119 $ 394 $ 338 Additionally, during the three months ended September 30, 2022, we recognized a $ 9.3 million expense for the accelerated vesting of CatchMark equity awards related to the CatchMark merger which is included in CatchMark merger-related expenses on the Condensed Consolidated Statements of Operations . See Note 13: CatchMark Merger for additional information. Performance Share Awards The weighted average grant date fair value of PSAs granted in 2023 was $ 61.21 per share. 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 number of shares actually issued, as a percentage of the amount subject to the PSA, could range from 0 % to 200 %. PSAs granted under the 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 performance measurement period, the recipients will receive dividend equivalents in the form of additional shares of common stock at the date of settlement equal to the dividends that would have been paid on the shares earned had the recipients owned the shares during the three-year period. The share awards are not considered participating securities. The following table presents the key inputs used in the Monte Carlo simulation to calculate the fair value of the performance share awards granted in 2023: Stock price as of valuation date $ 47.55 Risk-free rate 4.14 % Expected volatility 36.24 % Expected dividend yield 1 — Expected term (years) 3.00 1 Full dividend reinvestment assumed. Restricted Stock Units The weighted average fair value of all RSUs granted during the nine months ended September 30, 2023, was $ 47.01 per share. The fair value of RSUs granted equaled our common share price on the date of grant factoring in any required post-vesting holding periods. The RSU awards granted accrue dividend equivalents based on dividends paid during the RSU vesting period. Recipients will receive dividend equivalents in the form of additional shares of common stock at the date the vested RSUs are settled. Any forfeited RSUs will not receive dividends. The share awards are not considered participating securities.

Income Tax Disclosure [Abstract]
Income Taxes	NO TE 9. INCOME TAXES As a REIT, we generally are not subject to federal and state corporate income taxes on income from investments in real estate, including our timberlands, that we distribute to our stockholders. We conduct certain activities through our PotlatchDeltic taxable REIT subsidiaries (TRS) which are subject to corporate level federal and state income taxes. These 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 pre-tax book income or loss of the TRS, as well as permanent book versus tax differences and discrete items. During the second quarter of 2023, we reduced our federal-effected deferred blended state tax rate as a result of changes in tax rates and tax laws enacted during the quarter in certain states in which our TRS subsidiaries operate. The effect of the change resulted in a $ 1.0 million reduction to our net deferred tax liability and an offsetting reduction to tax expense, all of which was recorded as a discrete item in the second quarter of 2023.

Pension Annuitization In March 2022, we transferred $ 75.6 million of our qualified pension plan (the Plan) assets to an insurance company for the purchase of a group annuity contract. As a result of the transaction, the insurance company assumed responsibility for annuity administration and benefit payments to select retirees and terminated vested participants, with no change to participants' pension benefits. We recorded a non-cash pretax settlement charge of $ 14.2 million in non-operating expense, net, as a result of accelerating the recognition of actuarial losses included in Accumulated Other Comprehensive Income that would have been recognized in future periods. The settlement triggered a remeasurement of plan assets and liabilities.

CatchMark Merger

Business Combination and Asset Acquisition [Abstract]
CatchMark Merger	NOTE 13. CATCHMARK MERGER On September 14, 2022, CatchMark Timber Trust, Inc. (CatchMark) and CatchMark Timber Operating Partnership, L.P. (the Partnership) merged into a wholly owned subsidiary (Merger Sub) of PotlatchDeltic, pursuant to the terms of a merger agreement dated May 29, 2022, with the Merger Sub surviving the mergers. CatchMark owned approximately 348,000 acres of superior site index timberlands located in Alabama, Georgia and South Carolina. The CatchMark timber and timberlands assets and operations are included in our Timberlands segment within the Southern region. As a result of the merger, we issued approximately 11.5 million shares of PotlatchDeltic common stock, including: (i) 11.3 million shares in exchange for the outstanding shares of CatchMark common stock, which included unvested CatchMark share-based awards that fully vested upon closing of the merger; and (ii) 0.2 million shares in exchange for the Partnership OP Units. We capitalized transaction costs of $ 9.3 million for items such as investment banking fees, legal services, and other professional fees directly attributable to the merger. We accounted for the transaction as an asset acquisition as substantially all the value of the acquisition was concentrated in the acquired timber and timberlands. We allocated the cost of the acquisition to the net assets acquired based on their relative estimated fair value on the acquisition date. This resulted in an allocation of $ 782.3 million to timber and timberlands, $ 3.0 million to intangible assets, $ 32.0 million to other assets and $ 23.6 million for cash acquired in the merger. Additionally, we assumed $ 323.1 million of liabilities, including $ 300.0 million of outstanding long-term debt. Immediately following the merger, we refinanced $ 277.5 million of the long-term debt assumed in the merger and repaid the remaining $ 22.5 million with cash on hand. We also entered into $ 277.5 million of interest rate swaps to fix the interest rates on the refinanced long-term debt. During the three and nine months ended September 30, 2023, we incurred non-capitalizable merger costs in connection with the CatchMark merger of appro ximately $ 0 and $ 2.5 million, re spectively, primarily consisting of post-merger fees for professional services. During the three and nine months ended September 30, 2022, we incurred non-capitalizable merger costs of $ 26.0 million in connection with the CatchMark merger, primarily for severance benefits, tax gross-up payments to holders of Partnership OP Units and share-based compensation for the acceleration of CatchMark equity awards that fully vested upon closing of the merger and were allocated to the post-merger period. These non-capitalizable merger costs are included in CatchMark merger-related expenses in our Condensed Consolidated Statements of Operation .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 14. COMMITMENTS AND CONTINGENCIES At any given time, we are subject to claims and actions incidental to the operations of our business. Based on information currently available, we do not expect that any sums we may have to pay in connection with any legal proceeding would have a materially adverse effect on our consolidated financial position, operating results or net cash flow. ENVIRONMENTAL MATTER Pursuant to the 2002 Asset Purchase Agreement under which Sappi Cloquet LLC (Sappi) purchased our Cloquet, Minnesota pulp and paper mill (the Plant), we agreed to indemnify Sappi from certain environmental liabilities accruing from the pre-sale operations of the Plant. In February 2021, we were notified by Sappi that the Environmental Protection Agency (EPA) contacted Sappi about the opportunity to participate with the Minnesota Pollution Control Agency (MPCA) and the EPA in a voluntary federal sediment remediation program under the Great Lakes Legacy Act (GLLA) for a project in the St. Louis River Area of Concern, which runs from Cloquet, Minnesota to Lake Superior. The GLLA is a sediment remediation program administered by EPA that provides up to 65 % federal funding for the remediation of contaminated sediments in the Great Lakes region. The GLLA program requires at least 35 % cash or in-kind contributions from non-federal sponsors (NFS). The EPA’s invitation to Sappi made no demands on or claims against Sappi, nor have EPA or MPCA made any demands or claims against PotlatchDeltic. The identified sediment remediation project (the Project) at Thomson Reservoir is downstream from the Plant. The Plant was identified for potential partnership with EPA and MPCA on the Project based on the Plant’s historic direct discharges of wastewater and leachate from the Plant’s landfill into the St. Louis River prior to the re-routing of the discharges in 1979 to a public wastewater treatment facility. After multiple discussions with the MPCA and completion of our extensive due diligence on this matter, we informed the MPCA in January 2023 that we were interested in voluntarily participating in the Project, subject to an equitable division with the MPCA of the NFS share of the costs. We executed a Project agreement with the EPA and the MPCA in October 2023. Although no contracts for the remediation work itself have been executed to date, our share of the total Project costs is estimated between $ 5.6 million and $ 6.7 million. At September 30, 2023, we have accrued $ 5.6 million for our estimated contribution to the Project. While it is reasonably possible that costs may change as the Project develops and work contracts are executed, we are unable to estimate at this time the amount of change, if any, which may be required for our share of this matter in the future.
