FY2015The Northwestern Great Basin ecoregion is one of the most intact ecosystems in the west. It is also a biological hotspot for migratory birds, greater sage-grouse and a stronghold for pronghorn antelope. However, altered fire regimes, invasive species, water scarcity, development, and climate change threaten the integrity of this landscape. Several efforts are ongoing for individual species, specific threats or sub-geographies, and over 60 existing plans and assessments have been identified for the region. This project will pull the pieces together to create a holistic view of shared priorities on the landscape.

Land facets were created by combining 3 rasters: elevation (seven 600-m bands), soil orders (11 classes) and slope (3 breaks) to produce a 270-m resolution grid. 162 land facets were created, ranging in size from over 9 million hectares in the plateaus of the Columbia Plateau to less than 1,000 hectares in steep, high elevation habitats. These 162 facets were stratified by ecoregions to produce 794 ecofacets which underlie the spatial distribution of biodiversity and the region’s biological richness. Soil Order: Soil orders reflect both geology and time and are based largely on soil forming processes, including exposure to climatic factors and biological processes, as indicated by the presence or absence of major...

This map depicts the density of "More Resilient" cells (defined as the top two quintiles from the stratified resilience dataset) within a 3-km radius of every cell. This provides important additional context when making land protection or restoration decisions. Cells with higher density values are embedded in a larger resilient landscape. These areas are more likely to support biodiversity and ecological function over time in a changing climate. To quantify resilience at the landscape scale, we used a density function, where all cells classified in the final top two resilience quintiles were included in the density calculations, regardless of their underlying Ecofacet, and all other cells were ignored. Looking...

This map is being used as part of the Conserving Nature’s Stage Land Protection Grant process in Idaho, Oregon and Washington. Please see instructions on how to contribute information on potential projects and help The Nature Conservancy and the Land Protection Committee identify land protection priorities for the 2016-2017 grant program by going to http://nature.org/resilienceNW_LandGrants. The dataset consists of the upper two quintiles of unconverted resilient lands with the exclusion of clusters of 10 or fewer contiguous resilient pixels (180 or fewer acres) in areas scoring below 40% for resilience density. The resilience and resilience density layers this dataset is based on are viewable on other maps...

Permeability refers to the degree to which a landscape sustains ecological processes and supports movement of many species by virtue of the structural connectedness of its natural systems (Meiklejohn et al 2010). We used resistant kernel analysis (Compton et al. 2007) to map permeability as a focal statistic based on the resistance data from the terrestrial condition dataset. The analysis evaluates the capacity for ecological flow outward from each focal cell into its local neighborhood up to a maximum of 3-km, then combines the results into a final, study-wide surface. Perm_Score: Our permeability analysis evaluates the connectivity of a focal cell to its ecological neighborhood when the cell is viewed as a source;...
