California Landscape Metrics (CLM)
Consolidating Metrics from all four Regional Resource Kits (RRK)
Purpose:
Reducing the risk of large, high intensity fire (and other mega-disturbances) through forest treatments is a management imperative in California. A Strategy for Shared Stewardship (2018) and the USFS Wildfire Crisis Implementation Plan (2022) reinforce specific goals for pace and scale of strategic forest treatments over the next decade. Concurrently, the State of California has issued a new Wildfire and Forest Resilience Action Plan (2022) , designed to strategically accelerate efforts to restore the health and resilience of California landscapes through a joint federal and state framework.
High quality geospatial data are essential to drive analytic tools for planning and investments to restore and conserve California's landscapes. To support these initiatives, an interagency team of scientists from the USDA Forest Service Pacific Southwest Research Station (PSW), USDA Forest Service Region 5, CAL FIRE's Fire and Resource Assessment Program (FRAP), the Climate and Wildfire Institute (CWI), and researchers from the University of California Berkeley, University of California Irvine, and the USDA California Climate Hub collaborated to develop a comprehensive set of mapped data layers. These high quality data developed from ecological modeling techniques, informative analytical approaches and the resulting credible scientific outputs enable landscape level assessment to inform and support large landscape restoration planning and implementation.
The data layers included are meant to assist land managers in assessing their current landscape and plan for treatments to enhance resilience to human and natural disturbances. Thus, each layer represents what the interagency team believes are the most relevant and reliable geospatial data currently available. Each layer is supported by published data and/or was developed using credible scientific methods. The methods for developing each layer are documented in the metric dictionary; however, the accuracy of each layer has not been quantified. Data layers will be updated and refined as methods and source data evolve and improve.
Data Availability:
Data for the four regions were updated in April 2024 to bring in some corrections and updates to improve each kit.
The “California Landscape Metrics” (CLM) compilation was added in October 2024 and includes the data for all regions of California.
Many CLM metrics cover the entire state, others cover only a portion of the state. Users can access the data for the maximum geographic extent available for that particular dataset.
Future software modifications by the Task Force Data Hub will make it possible for a user to use any number of geographic “Areas of Interest”, regions, counties, watersheds, or even a shapefile that defines a project area that a user can submit, to define the area for which they want data. That will be available either later in the fall of 2024 or early 2025.
The CLM will make access to the metrics more effective overall, because:
- Maintenance will be much more efficient:
- Files are all stored in one directory
- Only one metric dictionary is needed
- Updates/changes are only needed once, not four times
- Users can see what is available in the entire CLM suite, they do not have to search four kits
- Users can access whatever area of interest in relevant to them, avoiding confusion for areas along the boundary of regions
- We are still able to retain the tiering of metrics; some do, in fact, cover the entire state (tier 1); others are inherently only relevant to and available for certain portions of the state (tier 2)
We have labeled the CLM as version 5, to enable a fresh start to the kit. We will retain the structure of housing the metrics within the Regional Resource Kits while people become familiar with these changes. Ultimately this will be the singular repository for metrics made available by the Task Force.
The original Regional Resource Kits, and now the California Landscape Metrics have adopted the "Framework for Resilience" to provide a structure for assessing landscape conditions, setting objectives, designing projects, and measuring progress towards social-ecological resilience. There are ten pillars that represent the desired outcomes of landscape resilience. Each of the pillars provides a series of metrics (the data layers) for assessing landscape conditions and verifying that actions meet resilience objectives.
Metrics describe the characteristics of elements in quantitative or qualitative terms. Users can use metrics to assess, plan for, measure, and monitor progress towards desired outcomes and greater resilience.
Data Access:
A total of 199 metrics has been developed statewide and are now available for download. Some cover the entire state, others are relevant and available for only a portion of the state. Users will see all data available for whatever area of interest they choose. Most data layers are available at 30 m resolution (i.e. pixels are 30 meters on a side), some are available at the resolution of the original data set (e.g. the climate refugia data are 270-meter pixel resolution).
Each data layer is available for viewing by downloading an image and the full data can also be downloaded as a zip file. In addition, the metadata are available for download. Links for all are located immediately adjacent to the listing of the data layer below under each of the ten pillars.
Use Constraints:
These data were collected from multiple sources, some which have specified use constraints. All data developed by the U.S. Government can be used without additional permissions or fees. Data developed by other sources may have other constraints. Please check each metric and their source to determine if any additional disclaimers exist. A full list of disclaimers by organization is available at the end of this webpage.
Intended use includes regional assessments of vegetation cover, land cover, or land use change trends, total extent of vegetation cover, land cover, or land use change, and aggregated summaries of vegetation cover, land cover, or land use change. Further use includes applying these data to assess management opportunities for treatments to restore landscape resilience using GIS software and specialized Decision Support Tools.
There are use disclaimers and restrictions for specific data layers. Please review the information below under "Data Credit and Disclaimers" at the bottom of this page and consult any specifics for each metric when downloading data.
Data Products:
The metrics are organized by the 10 pillars of resilience in the "Framework for Resilience". Each pillar represents a resource outcome associated with resilient forest landscapes. We have 47 metrics covering the entire state, spanning the 10 pillars. The Metrics describe the characteristics of the elements of each pillar in quantitative or, in a few cases, qualitative terms. Metrics are used to assess current conditions, plan treatments, and monitor progress toward desired outcomes and greater resilience. Metrics are selected to be informative, meaningful, and actionable to meet the needs of management.
The metrics are divided into three "tiers." Among all these metrics, some are created and relevant statewide and are included in the CLM data.
Tiers:
Tier 1 - metrics that are a single, consistent data layer, developed statewide. Example: Annual Burn Probability.
Tier 2 - metrics relevant to and available for a single Region or relevant to multiple Regions but data layers differ among Regions because of varied data availability (sources) across Regions. Example: California gnatcatcher habitat suitability.
Tier 3 - metrics are those that would be of interest to some land managers for specific applications but not included in the CLM. Example: Distribution of the Quino checkerspot butterfly.
Null values:
Some data layers contain null values. We point this out here so users of the data will be aware and take whatever measures appropriate as they use and analyze the data. For some raster datasets in the CLM, areas have been masked (blanked) out and have a cell value of NoData (also referred to as null, NaN or missing). We, as producers and users of the data, cannot ignore NoData or fill them with zeros, since zero is often a valid value for some datasets. Removing NoData cells is not an option, a raster is a continuous grid. For users of the data performing further analyses and combining or "stacking" rasters, these NoData cells will mask out all values in that location in the output. To avoid this issue, the user must create values for the cells before combining them (i.e. 999 or any numeric value that is not real and clearly out of the range of the other values). Reasons for masking (blanking) out cells in CLM data:
- Cells are located in water bodies (e.g., lakes, reservoirs, or large rivers)
- Cells are located in urban areas
- Cells are located in areas used for irrigated agriculture
- Cells contain no information relevant to the dataset (e.g. for a streams data layer, areas outside of streams have NoData)
- Area (cells) subject to fire or other disturbance but the post disturbance condition or value is unknown
File Naming Convention:
A standardized naming convention, as follows, has been developed to help organize files and describe what is contained:
{regional prefix if applicable, none if statewide}_{description}_{vintage of source data}_{latest publish date}_{tier #}_{CLM version #}.{file format}
Examples:
- PotentialTotalSmoke_202209_202312_T1_v5.tif
- NorCal_BiomassTrmntCostHigh_202309_202401_T2_v5.tif
- CumulTreeCoverLoss_19912020_202312_T1_v5.tif (vintage represents a range from 1991 - 2020)
Use of prefixes
- If a layer exists in every region, it is Tier 1 and does not get a regional prefix.
- If a layer does not exist in every region but it could if statewide coverage was available, it is Tier 2 and gets a regional prefix. For example, F3 layers (see Heavy Fuels) only exist for the Sierra Nevada, but we hope in the future datasets like this could be developed statewide.
- If a layer does not exist in every region and it never will, it is Tier 2 and gets no prefix.
The following are the definitions for the four regional prefixes used in file naming.
- SNV = Sierra Nevada
- SoCal = Southern California
- CenCal = Central California
- NorCal = Northern California
The metrics (by Pillar) included are listed below in brown. After each metric description the source of the data is displayed followed by a regional prefix if the data are only found in one or more regions. The addition of new metrics will be designated by noting as “new”. Similarly, there could be data layers that have been removed. Users should check the previous version and compare with this version to identify layers removed.
CLEAN AIR IS IMPORTANT to human health and wellness, clean water, biodiversity, and ecosystems. Catastrophic wildfires degrade air quality and cause respiratory illnesses that affect millions of people, especially children and people who work outdoors. Furthermore, people prefer to enjoy the outdoors when it is safe to breathe, and the skies are clear. Smoke from wildfires discourages recreation and disrupts businesses and local economies. Land managers seek to improve forest health and resilience by using prescribed fire to reduce the risk of uncharacteristic fire and smoke.
OUTCOME: Emissions from fires are limited to primarily low- and moderate-severity fires in wildland ecosystems. Forests improve air quality by capturing pollutants.
Particulate Matter
BIODIVERSITY PLAYS A MAJOR ROLE in our ecosystems and society. Native plants and animals help forests recover after a fire, control flooding and soil erosion, and cycle nutrients. Biodiversity also holds cultural value, including Native American uses, and provides recreational benefits like birdwatching. Greater species diversity promotes adaptability and helps ecosystems withstand and recover from disturbances, including those caused by a changing climate.
OUTCOME: The network of native species and ecological communities is sufficiently abundant and distributed across the landscape to support and sustain their full suite of ecological and cultural roles.
Species Diversity
Focal SpeciesPlants
CARBON SEQUESTRATION IS THE PROCESS by which carbon dioxide is taken up by trees, grasses, and other plants and stored as carbon in biomass and soils. Resilient forests and wetlands can be net sinks of carbon and can play an important role in reducing greenhouse gas emissions into the atmosphere, thereby mitigating climate change. Forest products also play a role in storing carbon for decades in building materials, thereby delaying emissions.
OUTCOME: Carbon sequestration is enhanced in a stable and sustainable manner that yields multiple ecological and social benefits.
StorageStability
ECONOMIC DIVERSITY INCREASES business opportunities that provide regional economic vitality and additional benefits to rural and vulnerable populations. Resilient forests provide ecosystem services and forest products that in turn provide a foundation for many local and regional economic activities and employment opportunities, including recreation, tourism, and natural resource management industries.
OUTCOME: Forest management and outdoor activities support a sustainable, natural-resource-based economy, particularly in rural communities.
Wood Product Industry
DUE TO CLIMATE CHANGE and other drivers, wildfires increasingly threaten homes and communities, especially in the wildland-urban interface. Fire adapted communities are knowledgeable and engaged. They accept fire as part of the surrounding landscape, take action to reduce their vulnerability to fire, and adapt to live safely with fire.
OUTCOME: Communities have adapted to live safely in forested landscapes and understand the significance of fire to maintaining healthy forests. They have sufficient capacity to manage desired fire and suppress unwanted fire.
Hazard
FIRE IS AN INTEGRAL PART of most California forest and shrubland ecosystems, which are evolutionarily adapted to fire. Ideally prescribed fires and managed wildfires would be allowed to burn across the landscape periodically. They would burn primarily at low to moderate severity in a mosaic pattern that covers large areas, which would provide substantial ecological benefits. Because climate change generally increases the severity of fire dynamics, managing such dynamics will continue to grow in importance.
OUTCOME: Fire burns in an ecologically beneficial and socially acceptable way that perpetuates landscape heterogeneity and rarely threatens human safety or infrastructure.
Functional Fire
Severity
RESILIENT FORESTS PROVIDE many ecosystem services, including wildlife habitat, clean water, stable soils, recreational opportunities, biodiversity, wood products, and carbon sequestration. They also play an important role in both mitigating and adapting to climate change. Across the landscape, management activities and natural disturbances should maintain desired forest conditions, including forest heterogeneity and wildlife habitat.
OUTCOME: Vegetation composition and structure align with topography, desired disturbance dynamics, and landscape conditions, and are adapted to climate change.
Structure
Composition
Disturbance
A GROWING BODY OF EVIDENCE indicates that greater exposure to nature is associated with better health and well-being. California forests and shrublands allow people to build and maintain active cultural and social connections to a place. Resilient landscapes offer opportunities for people to connect with the natural environment through recreation experiences, culturally valued resources, and engagement in natural resource management and conservation.
OUTCOME: The landscape provides a place for people to connect with nature, to recreate, to maintain and improve their overall health, and to contribute to environmental stewardship, and is a critical component of their identity.
Equitable Opportunity
Recreation Quality
RESILIENT FORESTED WATERSHEDS are key for regional and statewide water security. The economic value of California's water far exceeds that of any other forest product. Water flows from forests into rivers that provide critical aquatic and wetland habitat, and that supply agricultural and drinking water for tens of millions of people. Forests serve as natural water collection, storage, filtration, and delivery systems. These functions will become more important as climate change intensifies.
OUTCOME: Watersheds provide a reliable supply of clean water despite wide swings in annual precipitation, droughts, flooding, and wildfire.
Quantity
Quality
WETLANDS PROVIDE critical habitat, filter and retain nutrient pollution, store carbon, enhance water quality, control erosion, and provide spaces for recreation. They are local and regional centers of biodiversity, and support species found nowhere else across western landscapes. Functional wetland ecosystems will serve increasingly important roles in buffering impacts from extreme climate events, and upland disturbances such as flooding and erosion.
OUTCOME: Meadow and riparian ecosystems provide multiple ecosystem services and are key linkages between upland and aquatic systems in forested landscapes.

Metric Dictionary:
These data have been assembled in one place to provide comprehensive access for land managers. Accompanying all the data is a metric dictionary which provides details on the nature of each metric. Each metric has been defined to help end-users of the data (and for use with any decision support tools) to understand:
- What tier is the metric in (1, 2, or 3)?
- Data vintage
- The definition meant by a given metric
- The expected use(s) of the metric
- The resolution of the developed data
- The data sources used to derive the metric
- The method of metric derivation
- The root file names
References have been included to help the reader understand potential methods for deriving metrics. It is our hope this information will help people make better use of all the assembled information and how it can best be used with various decision support tools. This dictionary will be updated periodically, as necessary.
