Dynamic mapping for a resilient future

TerrAdapt:Cascadia provides land managers and decision-makers across Washington and southern British Columbia with an always up-to-date, regional-scale perspective on our changing landscape and climate to help them achieve their conservation mandates in our rapidly changing world.

Planning for a Resilient Future

Across it's expansive forests, high mountain peaks, and arid shrubsteppe, Cascadia is experiencing severe impacts from our expanding human footprint and rapidly changing climate. To keep iconic species such as salmon, grizzly bear, wolverine, lynx, and sage grouse in our landscape requires that we act together across boundaries, with strong situational awareness of where the threats and opportunities exist, and the ability to manage our lands and waters adaptively. We co-developed TerrAdapt:Cascadia with our partners - including state, provincial, and federal agencies, First Nations and Tribes, and NGOs - to improve the region's capacity to monitor the changing landscape at scale, project future impacts of climate change, and prioritize strategic places for protection and restoration actions that increase resiliency in our natural systems.

Enabling Adaptive Management

TerrAdapt's dynamic data products have applications throughout the adaptive management cycle. Our regional monitoring and assessment products can be used to form a landscape-scale conservation plan, and then monitor and assess it's effectiveness in conserving habitat and connectivity. Our map and dashboard portals help users evaluate progress towards goals, report status and trends and provide feedback that can be used to adapt the plan to changing conditions over time. Because all our data products update automatically each year, managers always have the latest data seamlessly across our entire region. This enables a more modern and nimble form of adaptive management that can keep up with the pace and scale of change. 

Monitoring our Forests

TerrAdapt's forest structure monitoring metrics  - including canopy cover (right), canopy height, and tree diameter - help our partners track changing forest conditions so they can manage their lands adaptively in ways that support our region's diversity of wildlife and native habitats. For example, the Washington Department of Natural Resources will use these metrics in their Forest Action Plan, which will guide actions to restore and conserve Washington's forests.

These forests are essential to protecting biodiversity, fighting climate change, and safeguarding our air and water

Projecting Future Conditions

Our rapidly changing climate is driving widespread impacts to regional species and ecosystems. For example, warming temperatures are leading to reduced snowpack, more wildfires, and other impacts that are driving losses in lynx habitat in Washington and southern British Columbia. TerrAdapt allows lynx managers to see how predicted climatic changes, including precipitation and temperature (left), could shift the range of this species in our region, helping managers make climate-smart investment in lynx conservation.

Prioritizing Action

TerrAdapt works with partners to co-develop regional spatial conservation designs that prioritize landscapes for conservation actions like protecting or restoring habitat and mitigating movement barriers. Mapping these priorities using TerrAdapt's dynamic data allows the priorities to be dynamic too. For example, the map at right shows dynamic spatial priorities TerrAdapt co-developed with the Washington Shrubsteppe Restoration and Resiliency Initiative.

Our Work in Cascadia

TerrAdapt is working with dozens of partners across Washington and southern British Columbia. Explore our recent projects to learn more about our work in Cascadia.

Modeling Species Habitat


In partnership with state, provincial and federal partners in Washington and British Columbia, we have built a fisher habitat model that can be used to support recovery and conservation efforts across the region.

Monitoring Habitat Change


The Dashboard allows managers to monitor and summarize changes in habitat suitability over time using the TerrAdapt habitat model.

Explore Fisher Habitat Change

Species Modeling Approach


To build species models, TerrAdapt convenes experts to produce temporal habitat suitability and connectivity models. The Pacific fisher model was developed using a collection of telemetry datasets and temporal spatial data products from TerrAdapt from across Cascadia and ranges back to 1984.

Coordinated Monitoring

Átl'ka7tsem / Howe Sound Initiative

TerrAdapt is working with the Squamish Environment Society and the Átl'ka7tsem / Howe Sound Biosphere Region Initiative to support regional and local land managers in safeguarding and restoring vulnerable terrestrial habitat and pathways of wildlife using TerrAdapt tools and models.

Adaptive Land Management

Átl'ka7tsem / Howe Sound Initiative

Partners are leveraging their knowledge and TerrAdapt's tools to promote a shared understanding of the causes of biodiversity loss, support dynamic land use planning, and develop regional conservation strategies that align with Canada's 2030 Biodiversity Conservation Strategy.

Explore Forest Connectivity Change

Creating Baselines

Átl'ka7tsem / Howe Sound Initiative

Visualizing and quantifying forty years of landscape change and future projections of warming climate and ecosystem response is critical information for local and regional partners to create a baseline assessment of the area.

Support Land Planning

Stein Nahatlatch Initiative

TerrAdapt is supporting First Nations in Canada to establish Indigenous Protected and Conserved Areas. Leaders of the Stein Nahatlatch Initiative will be able to tap into nearly 40 years of land use data to communicate the importance of their region and support land management.

Account for Changing Climate

Stein Nahatlatch Initiative

Changes in climate patterns are expected to impact forest recovery in the Stein. TerrAdapt's projected climate and precipitation layers, developed from ClimateNA, will help support decision making on post-fire restoration planning in the valley.

Respond to Disturbance

Stein Nahatlatch Initiative

Land use plans must be able to adapt to disturbances such as wildland fire. TerrAdapt's dynamic mapping function supports land planners to identify where annual changes are taking place and how they may affect targets. Fires and logging have had a large impact on the forests in the Stein Nahatlatch valley.

Prioritizing Actions


TerrAdapt has partnered with the Washington Shrubsteppe Restoration and Resiliency Initiative to support partners to prioritize the arid lands of Eastern Washington for conservation actions that increase resilience.

Track Ecosystem Change


Seeing where and when change occurred in the ecosystem is critical for priority setting and tracking progress. As part of this project, TerrAdapt co-developed models of the Shrubsteppe ecosystem to define habitat suitability, core habitat blocks, and connectivity within Cascadia.

Integrating Species


The Greater Sage Grouse is a key species within the Shrubsteppe ecosystem that must be accounted for in spatial priority setting. A model of Sage Grouse habitat suitability and connectivity spanning over 30 years was co-produced with WSRRI to inform the priority-setting exercise.

Protected Area Planning

Ashnola Indigenous Protected Area

TerrAdapt is working with the Lower Similkameen Indian Band to support land monitoring and planning in the Ashnola Indigenous Protected and Conserved Area.

Monitor Disturbance

Ashnola Indigenous Protected Area

Fires in British Columbia have become more common and intense over the last decade, making it difficult to adapt management plans as the landscape changes each year. Quantifying fire and logging disturbance within the Ashnola and broader landscape is critical for land planning.

TerrAdapt's tools can also be combined with local and regional-level spatial data sources for rapid decision-making in manager's GIS platform of choice. For example, live fire boundaries and road layers can be overlaid with landsat, forest structure, and species layers from TerrAdapt in ArcGIS Online.
