Merger	Mar. 31, 2020
Business Combinations [Abstract]
Merger	On January 14, 2020, Pope Resources entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Rayonier, Inc., (“Rayonier”) and certain of its subsidiaries, and the Merger Agreement and merger were approved by Pope Resources unitholders on May 5, 2020. Upon consummation of the transaction, holders of limited partner units of the Partnership (including the depositary receipts therefor, the “Partnership Units”), will be entitled to receive, for each Partnership Unit, merger consideration consisting of (i) 3.929 common shares of Rayonier, (ii) 3.929 units of Rayonier Operating Partnership LP, or (iii) $125 in cash. Elections will be subject to proration to ensure that the aggregate amount of cash, on the one hand, and Rayonier common stock and Rayonier operating partnership units, on the other hand, that are issued in the merger would be equal to the amounts issued as if every Partnership Unit received $37.50 in cash and 2.751 Rayonier common shares or Rayonier operating partnership units. If elections for the Rayonier common shares and Rayonier operating partnership units are oversubscribed, then to reduce the effect of such proration Rayonier can, in its discretion, add additional equity (and decrease the amount of cash) payable to the Partnership unitholders making such election. The merger is expected to be completed on May 8, 2020, and is subject to the satisfaction (or waiver, if permissible under applicable law) of customary closing conditions, including the approval of the holders of a majority of the Partnership Units.

Revenue from Contract with Customer

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer

Revenue is measured based on the consideration specified in a contract with a customer. The Partnership recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. Included in “Accounts receivable, net” are $4.1 million and $2.2 million of receivables from contracts with customers as of March 31, 2020, and December 31, 2019, respectively.

Significant changes in the contract asset balance during the period were as follows, and there were no contract liabilities as of March 31, 2020, and December 31, 2019 (in thousands):



Contract assets, December 31, 2019	$	2,765
Revenue recognized from changes in estimates of variable consideration	4
Transferred to receivables from contract assets	(408		)
Contract assets, March 31, 2020	$	2,361

The contract assets in the table above represent rights to consideration for timber deeds transferred to the customer and are related primarily to the Funds Timber segment. These contracts provide the customer the legal right to harvest timber on a designated portion of the Funds’ or Partnership’s property. The value of a timber deed contract is determined based on the estimated timber volume by tree species multiplied by the contracted price. The contract consideration is considered variable because the timber volume by species is an estimate until the harvest is completed. The contract assets are transferred to receivables when the rights to consideration become due under the contract. Customers may harvest the timber at their discretion, within a time period and operational parameters stated in the contract.

The following is a description of principal activities, separated by reportable segments, from which the Partnership generates its revenue.

Partnership Timber and Funds Timber

Log sale revenue in these two segments is recognized when control is transferred, and title and risk of loss passes to the customer, which typically occurs when logs are delivered to the customer. Revenue in these two segments is earned primarily from the harvest and sale of logs from the Partnership’s and Funds’ timberland. Other revenue in these segments is generated from the sale of rights to harvest timber (timber deed sales), commercial thinning, ground leases for cellular communication towers, royalties from gravel mines and quarries, and land use permits. Timber deed sales are generally structured so that the customer pays a contracted price per volume, measured in thousands of board feet (MBF), and revenue is recognized when control is transferred to the customer, which generally occurs on the effective date of the contract. Commercial thinning consists of the selective cutting of timber stands that have not yet reached optimal harvest age. However, this timber does have some commercial value and revenue is based on the volume harvested. Royalty revenue from gravel mines and quarries is recognized monthly based on the quantity of material extracted.

The following table presents log sale and other revenue for the Partnership Timber and Funds Timber segments:



(in thousands)	Quarter ended March 31,
	2020		2019
Partnership Timber
Log sale revenue	$	9,861	$	14,722

Log sale revenue	$	11,999	$	8,860
Timber deed sale revenue	4		—
Other revenue	47		580
Total revenue	$	12,050	$	9,440

Timberland Investment Management (TIM)

Fee revenue generated by the TIM segment for managing the Funds includes fixed components related to invested capital and acres under management, and a variable component related to harvest volume from the Funds’ tree farms. These fees, which represent an expense in the Funds Timber segment, are eliminated in consolidation. The TIM segment occasionally earns revenue from providing timberland management-related consulting services to third-parties and recognizes such revenue as the related services are provided.

Real Estate

The Real Estate segment’s activities consist of investing in and later selling improved properties, holding properties for later development and sale, and managing commercial properties. Revenue is generated primarily from sales of land, sales of development rights, known as conservation easements (CE’s), sales of unimproved land from the Partnership’s timberland portfolio, and residential and commercial rents. Revenue on real estate sales is recorded on the date the sale closes. When a real estate transaction is closed with obligations to complete infrastructure or other construction, the portion of the total contract allocated to the post-closing obligations may be recognized over time as that work is performed, provided the customer either simultaneously receives and consumes the benefits as we perform under the contract, our performance creates or enhances the asset controlled by the customer, or we do not create an asset with an alternative use to the customer and we have an enforceable right to payment for the performance completed. Progress towards the satisfaction of our performance obligations is generally measured based on costs incurred relative to the total cost expected to be incurred for the performance obligations.

The following table breaks down revenue for the Real Estate segment:

Sale of unimproved land	$	—	$	22

Supplemental Balance Sheet Disclosures

ORM Timber Fund II, Inc. (Fund II), ORM Timber Fund III (REIT) Inc. (Fund III), and ORM Timber Fund IV LLC (Fund IV), collectively “the Funds”, were formed by Olympic Resource Management LLC (ORMLLC), a wholly owned subsidiary of the Partnership, for the purpose of raising capital to purchase timberlands. The objective of these Funds is to generate a return on investments through the acquisition, management, value enhancement, and sale of timberland properties. Each fund is organized to operate for a specific term from the end of its respective investment period; 10 years for each of Fund II and Fund III, and 15 years for Fund IV. Fund II, Fund III, and Fund IV are scheduled to terminate in March 2021, December 2025, and December 2034, respectively.

Pope Resources and ORMLLC together own equity interests totaling 20% of Fund II, 5% of Fund III, and 15% of Fund IV. The Funds are considered variable interest entities because their organizational and governance structures are the functional equivalent of a limited partnership. As the managing member of the Funds, the Partnership is the primary beneficiary of each of the Funds as it has the authority to direct the activities that most significantly impact their economic performance, as well as the right to receive benefits and the obligation to absorb losses that could potentially be significant to the Funds. Accordingly, the Funds are consolidated into the Partnership’s financial statements. The obligations of each of the Funds are non-recourse to the Partnership.

The assets and liabilities of the Funds as of March 31, 2020, and December 31, 2019, were as follows:

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies Disclosure

The Partnership had an accrual for estimated environmental remediation costs of $9.9 million and $10.0 million as of March 31, 2020 and December 31, 2019, respectively. The environmental remediation liability represents management’s estimate of payments to be made to remedy and monitor certain areas in and around Port Gamble Bay, Washington. The liability at March 31, 2020 is comprised of $993,000 that management expects to expend in the next 12 months and $8.9 million thereafter.

In December of 2013, a consent decree (CD) and a Clean-up Action Plan (CAP) related to Port Gamble Bay were finalized with the Washington State Department of Ecology (DOE) and filed with Kitsap County Superior Court. Construction activity commenced in late September 2015. The required in-water construction activity was completed in January 2017. By the end of the third quarter of 2017, the sediments dredged from the Bay were moved to their permanent storage location on property owned by the Partnership a short distance from the town of Port Gamble. This effectively concluded the component of the project related to the in-water cleanup of Port Gamble Bay. The two remaining components of the project consist of restoration projects to address Natural Resource Damages (NRD) and the cleanup of the millsite.

As disclosed previously, certain environmental laws allow state, federal, and tribal trustees (collectively, the Trustees) to bring suit against property owners to recover damages for injuries to natural resources. Like the liability that attaches to current property owners in the cleanup context, liability for natural resource damages (NRD) can attach to a property owner simply because an injury to natural resources resulted from releases of hazardous substances on that owner’s property, regardless of culpability for the release. In the case of Port Gamble, the Trustees are alleging that the Partnership has NRD liability because of releases that occurred on its property. The Partnership has been in discussions with the Trustees regarding their claims and the alleged conditions in Port Gamble Bay, and has also been discussing restoration alternatives that might address the damages the Trustees allege. These discussions have progressed to the point where a short list of restoration projects has been identified that would resolve the Trustees’ NRD claims, and management is hopeful that a settlement agreement will be reached by mid-year 2020.

With respect to the millsite, in early 2019, the Partnership submitted the final remedial investigation/feasibility study (RI/FS) and draft Cleanup Action Plan (CAP) to DOE for the millsite cleanup. The CAP and consent decree for the millsite are expected to be finalized during mid-year 2020, following a public review period.

For both the NRD restoration and millsite cleanup components of the liability, it is reasonably possible that cost estimates could change. We currently expect the NRD restoration projects and the millsite cleanup to occur over the next two to three years.

Finally, there will be a monitoring period of approximately 10 to 15 more years during which the Partnership will monitor conditions in the Bay, on the millsite, and at the storage location of the dredged and excavated sediments. During this monitoring phase, conditions may arise that require corrective action, and monitoring protocols may change over time. In addition, extreme weather events could cause damage to the sediment caps that would need to be repaired. These factors could result in additional costs.

Activity in the environmental liability is as follows:

Unusual or Infrequent Items, or Both, Disclosure	On March 11, 2020, the World Health Organization declared the novel strain of coronavirus (COVID-19) a global pandemic and recommended containment and mitigation measures worldwide. On March 13, 2020, the United States declared a national emergency concerning the outbreak, and all states and several municipalities have declared public health emergencies. The COVID-19 pandemic has introduced significant economic and business uncertainty, along with volatile financial market conditions. The states in which we operate have issued stay-at-home orders. However, our timberland-related businesses have been deemed essential businesses in those states. As such, we continue to operate these businesses at full capacity where market conditions allow, while maintaining the health and safety of our employees, contractors, suppliers and customers. Towards the end of the first quarter of 2020, business slowdowns resulting from COVID-19 began to have a negative impact on log prices. The ongoing impact on log prices, or our business more generally, is uncertain at this time.
