Description

This indicator measures the acres of farmland permanently protected from development through agricultural or conservation easements. Farmlands can provide wildlife habitat, reduce air pollution, and mitigate the spread of urban heat islands while providing quality, locally sourced foods. Protecting farmlands can help slow the conversion of farmlands to non-agricultural uses, though conservation easements do not increase the amount of farmland actively used nor ensure that the land produces crops in the future. This indicator can help us understand progress expanding the protection of farmland across the region.

Conversion of farmland poses a major challenge to the health of Puget Sound and its communities. The loss of these important lands can undermine local and regional food security, reduce resilience to climate change, and disrupt wildlife habitats. Conservation easements – agreements which restrict the allowed uses on land and support landowners financially – play a critical role in protecting land from conversion. Agricultural easements and other types of conservation easements offer environmental, ecological, or scenic protections, which can benefit farming, habitat biodiversity, and the long-term viability of agricultural lands.

Agriculture in Puget Sound contributes markedly to the local economy and to food supply around the nation. Whatcom County grows more than 65 percent of the nation’s frozen red raspberry supply, while Skagit County contributes roughly 90 percent of all red potatoes grown in Washington state[1]. Counties with smaller agriculture footprints still contribute valuable meats, fruits, and vegetables to local markets. While the Puget Sound region boasts a vibrant local food scene, farmers are facing challenges that impact the sustainability and viability of agriculture ventures.

The Farmland Protection Progress Indicator combines federal, state, and local data sources on protected lands to measure the amount and rate of farmland protection through conservation easements in the Puget Sound region. Conservation easements are considered the most permanent form of protection afforded to a parcel of land. The indicator does not capture other types of protection offered through mechanisms like zoning, agricultural buffers, right-to-farm ordinances, local or state farmland mitigation requirements, and cluster or conservation development regulations. These additional mechanisms offer some protection but are often inconsistently enforced and less protective than easements.

Conservation easements are not a silver bullet for protecting farmland. Farmland protection through conservation easements does not increase the land available for crop production, it maintains it. Once farmland is developed, it often cannot be regained, and farmland conversion is outpacing farmland protection. Easements also do not ensure that managing farmers will always have the interest and work force required to farm the land. Climate change, water availability, crop disease, and access to labor and food processing infrastructure are just a few factors that impact a farmer’s ability to maintain their land and business sustainably. While land may be protected with easements, additional strategies must be enacted across Puget Sound to support the viability of agriculture businesses.

Despite these caveats, this indicator offers one way that local jurisdictions and the Puget Sound recovery community can evaluate progress towards permanently protecting its critical agricultural land. This indicator can help illuminate drivers of and challenges to protecting farmland for our communities and future generations. Complementary economic and social analyses would offer additional insights into trends in farmland protection and conversion in Puget Sound.

Key Progress Indicator Results

A substantial acreage of farmland was permanently protected through easements prior to 2013. In 2022 and 2023, the region protected 811 fewer acres of farmland than during the previous reporting period (2020-2021). The region is thus not making progress increasing the rate of farmland protected and this indicator is “getting worse”. 

As of 2023, 55,364 total acres of farmland have been protected through easements across all years in Puget Sound. 

Total acres of farmland protected vary markedly by county and two-year reporting period between 2014 through 2023. The majority of protected farmland was enrolled in easements in 2013 and prior (40,902 acres). 

  • The highest number of acres enrolled in conservation easements occurred between 2014 and 2015 (3,996 acres protected), though the 2020-2021 period also saw substantial protection (3,173 acres protected).
  • King and Skagit counties had the highest totals of farmland protection between 2014-2023, with a total of 16,447 acres protected in King County and 16,182 acres protected in Skagit County. Mason and Kitsap counties saw the smallest totals of farmland protection over time (134 and 235 acres each, respectively).
  • 40,902 acres (74 percent of total protected acres) were enrolled in easements in 2013 or prior, or through undated agreements. 14,462 acres (26 percent of total protected acres) were enrolled in easements between 2014 and 2024. 
Methods
Monitoring Program
Data Source
  • Protected Agricultural Lands Database (PALD), Farmland Information Center, American Farmland Trust, accessed in Winter 2024-2025
  • Protected Areas Data of the US (PAD-US), U.S. Geological Survey, U.S. Department of the Interior, accessed in Winter 2024-2025
  • Compiled county and local land trust data, county programs, Puget Sound, accessed in Winter 2024-2025

The Farmland Protection Progress Indicator relies on the synthesis of three data sources to capture acres enrolled in conservation and agricultural easements across Puget Sound. The indicator team requested local sources of easement data from Puget Sound counties. These easement data were then paired with the national Protected Areas Data of the US (PAD-US) and Protected Agricultural Lands Database (PALD) datasets of established easements to create a comprehensive view of protected farmland acres.

Once these data were compiled, the indicator team conducted a manual review to remove overlapping easements, prevent double-counting of easements, and ensure easements correctly pertain to land used for agriculture. Where there were inconsistent attributes related to easements across multiple data sources, the local data attributes were used. The indicator team researched any inconsistencies with parcel boundaries across datasets to determine accurate parcel locations. 

To ensure easements pertain to land used for agriculture, the indicator team used aerial imagery and looked for irrigated pastures with vibrant green, fine textured, or geometrically shaped fields with uniform color and defined boundaries. There are many farms that likely have other uses on their land (e.g., wedding venues, agrotourism, watershed restoration, etc.) in addition to farming activities. These lands are likely still important to the farm business overall and to the presence of agriculture across the Puget Sound region, so they are counted as part of the easement.

The indicator team then completed spatial overlays of additional data (listed below) with easement data to determine whether a given protected parcel was in an urban growth area (UGA) and what zoning category the protected parcel fell within.

 

Easements were sorted into two-year reporting periods between 2014 and 2024 based on enrollment date or characterized as enrolled “2013 or prior” or “year unknown” as appropriate. Results were calculated at the parcel scale and summarized at the county- and Puget Sound region-scale. Results relate to the total acreage of a parcel, though not all acres within a parcel may be actively farmed. This indicator does not describe the portion of protected acres that are actively farmed; instead, the indicator gives a signal of the magnitude of farmland protected by conservation easements.

We evaluate progress by comparing the region's performance in the current two-year reporting period to its performance during the prior two-year reporting period (reference period). We make this comparison as sustained (period-over-period) increases in farmland protection is consistent with Puget Sound recovery goals. 

Reference period: 2021 through 2021

Current reporting period: 2022 through 2023

Two-year reporting periods in our dataset begin in 2014 through 2015. This roughly aligns with county comprehensive planning cycles; comprehensive plans are updated every 10 years and articulate land use goals in counties and cities across Puget Sound.  

 

Limitations:

  • Confidentiality of some conservation easements. Some easement locations and details are confidential, which limits the associated data available for analysis. The indicator team worked to ensure all confidentiality needs were met while reporting accurate totals of acres enrolled in easements. Confidentiality also impacted access to the establishment dates of some easements, which limited our ability to analyze when some easements were put in place. Roughly 5 percent of total protected acres have an unknown establishment year.
  • Manual review may have missed agriculture located in undesignated conservation easement categories. While we are reasonably confident that easements included in this study pertain to farmland, there were some easements without associated purposes. This impacted our ability to understand how specific easement programs and types (e.g., wetland conservation, general conservation, agriculture conservation) contribute to agriculture protection. Future research could explore different types of easements and easement programs and their effectiveness at protecting farmland in Puget Sound. 

 

Future Areas of Work: 

Despite limitations, this indicator helps demonstrate progress enrolling farmlands into permanent protection programs. Such protections may afford more opportunities to keep land in agricultural production. The development of this indicator yielded several priorities for future work to more accurately convey the drivers of and barriers to farmland protection.

  • Plan for agriculture viability in Puget Sound, so that protected farmland still has necessary support to be profitable and productive.
  • Explore characteristics of landowners enrolled in conservation easements and easement programs (e.g., land trusts) to better understand reasons for protection.
  • Explore how habitat restoration efforts impact the land base of active farmland and identify examples of multi-benefit conservation solutions that improve farm and habitat health.
  • Explore how easement enrollment has changed given rising costs of land; explore the economic dimensions of farmland protection and conservation easements.
Critical Definitions

Conservation easement: a voluntary and legally binding agreement between a landowner and organization (land trusts, county governments, Tribal governments, Conservation Districts, and other entities) that limits or prohibits the type and amount of development that may occur on a property and protects certain property features. Easement duration is typically permanent and is recorded on a parcel or parcels. Conservation easements in this report refer to all types, including but not limited to agriculture, wetland, forestry, riparian, natural resource, and historic preservation easements.

Conversion: the transition of land formerly used for farmland into another non-agriculture land use, like residential housing or commercial warehouses. Conversion is typically permanent.

Protection: protection refers to measures meant to prevent conversion of a farmland parcel (or parcels) to other non-agriculture uses. Protection can include permanent measures such as conservation easements or less permanent methods such as zoning. In this report, protection is defined as land held in conservation easements.

Zoning: municipal or local land use regulations that establish how land can be used or developed over time.

Interpretation of Results

Between 2022-2023, 2,362 acres of farmland were protected. This is a decline from the previous period (2020-2021), in which 3,173 acres of farmland were protected. We conclude that performance in this indicator is "Getting Worse."

Between 2014 through 2023, farmland protection varies significantly by county (Figure 2). 

  • King and Skagit counties have the most farmland enrolled in conservation easements (2,691 acres protected in King and 5,226 acres protected in Skagit between 2014-2023). Across all years (2013 and prior, and 2014 through 2023), King and Skagit counties have the most farmland enrolled in conservation easements (Figure 3). 
  • Clallam and Kitsap counties have the fewest acres of farmland enrolled in conservation easements (273 acres protected in Clallam and 132 acres protected in Kitsap between 2014-2023). Mason County had zero confirmed acres protected between 2014-2023, though all of Mason County's 134 protected acres were missing dates of enrollment (i.e., they may have been established between 2014-2023). 
  • The amount of farmland a county protected does not necessarily relate to the total amount of farmland present. Per the USDA 2022 census[1], Whatcom County had the most acres of land in farming across Puget Sound counties[2] but has a relatively low number of acres enrolled in conservation easements (2,725 acres across all years). Meanwhile, King County has the highest acres of farmland enrolled in conservation easements (16,447 acres across all years) yet the amount of King County’s land in farming in 2022[3] was close to the median across Puget Sound counties. The different totals of protected farmlands are likely affected by differing capacities of county agricultural and land protection programs.

Most of the protected parcels were smaller than 10 acres. 

  • 188 parcels of farmland were enrolled in conservation easements between 2014-2023. Of these, 201 parcels (54 percent of all protected farmland) were smaller than 10 acres. 
  • While smaller parcels represent the most parcels enrolled, larger parcels contribute a significant amount of acreage to the total of protected farmland. Only 10 parcels were larger than 499 acres, yet these 10 parcels represent 6,985 acres of protected farmland, or 48 percent of all protected farmland.

Most acres of protected farmland were in active agricultural zones, though a substantial proportion of protected farmland were in residential or mixed-use zones.

  • Most protected farmland are in zones planned for farming uses. 11,317 acres of protected farmland are in active agricultural zones (representing 78 percent of all protected farmland). 613 acres of protected farmland are in open space or other natural resource production zones. 
  • A sizable proportion of protected farmland is in zones planned for non-farming uses (e.g., development, transportation). 2,434 acres (16 percent) of protected farmland are in residential or mixed-use zones where development is encouraged. 
  • These results are somewhat expected, as many easement programs focus on land in agricultural zones. 

Pie chart showing the proportion of acres protected in general zoning categories. From largest to smallest, the totals of farmland protected by zoning category are as follows: active agriculture (11,317 acres), residential/mixed use (2,434 acres), open space/other resource production (613 acres), transportation (83 acres), undesignated (10 acres), and commercial/industrial (5 acres).

Most protected acres were located outside of Urban Growth Areas (UGAs) across Puget Sound. 

  • 330 acres of protected farmland are within UGAs, while 14,130 protected acres lie outside of UGAs.
  • 323 of these acres within UGAs are located in Island County. The remaining protected acres in UGAs are located in Thurston County (5 acres), King County (1 acre), and Whatcom County (1 acre).

The vast majority of protected farmlands are outside of urban growth areas. Island County (32 percent, 323 acres), Thurston County (1.1 percent, 5 acres), King County (0.1 percent, 1 acre), and Whatcom County (0.1 percent, 1 acre) are the only counties in which farmlands are protected within urban growth areas.

To keep up with development pressures, it is essential to continue investments in land conservation programs and evaluate the successes and barriers impacting these programs. Strong and well-enforced land use plans can help protect farmland even without a conservation easement. Strong partnerships between local governments, land use planners, and farmers can help identify effective types of conservation easement agreements to improve the protection of farmland.

The following strategies can help bolster conservation easement programs and ensure conserved land remains in active agricultural use:

  • Increased funding, capacity, and outreach for land trust programs to increase enrollment of farmland in conservation easements.
  • Strategic enrollment of productive and viable farmland and farmland more vulnerable to conversion in conservation programs to ensure protections are offered to priority agriculture areas.
  • Support for increased financial gains from conservation easements for landowners to keep up with development pressure and the rising costs of land ownership.
  • Agricultural and food system infrastructure near farms to support the production of crops, processing of agricultural products, and distribution and sale of agricultural products.
