Service Description:

The Nature Conservancy’s Resilient and Connected Network for the US

This map analysis identifies a network of resilient sites and connecting corridors that, if conserved, could sustain North America's natural diversity by allowing species to adapt to climate impacts and thrive. The network is a product of ten years of work by over 150 scientists. It is built from three independent data layers integrated into a network:

Representative Resilient Sites: Site Resilience is the ability of a site to sustain biodiversity and function even as the biota changes. It was measured as site with many topographically derived microclimates and the high local connectedness (microclimatic buffering). To ensure representation, site resilience was measured relative to other sites of the same geophysical setting (soil, geology, elevation) within ecoregions.
Climate Flow: Climate flow is the gradual movement of populations in response to climate change. It was measured using used a wall-to-wall flow analysis that simulated species moving along climatic gradients while avoiding anthropogenic barriers. From the analysis we identified key climate corridors and flow zones that will allow species to disperse, migrate and adapt to a changing climate.
Recognized Biodiversity Value: This map focused on a site’s current biodiversity value based on the presence of a rare species population, exemplary natural community or intact habitats. It was measured using The Nature Conservancy’s ecoregions portfolios, the State Wildlife Action Plan’s conservation opportunity areas, and Natural Heritage Program occurrences of biodiversity elements. \

The network covers 33% of the landscape, represents all geophysical environments, contains over 250,000 recognized biodiversity areas and is configured to maximize movement and flow. It is currently 44% secured against conversion to development. Alaska and Hawaii are underdevelopment as is a freshwater counterpart.

Legend Description:

Climate Corridor: a resilient area that is a narrow conduit in which movement of plants and animals becomes highly concentrated, often a riparian channel or linear ridgeline.
Climate Corridor with Recognized Biodiversity Value: a resilient climate corridor with rare species population, exemplary natural community or intact habitats.

Climate Flow Zone: a resilient area with high levels of plant and animal movement that is less concentrated than in a corridor, typically a large intact natural area. Flow refers to the movement of species populations over time in response to climate.
Climate Flow Zone with Recognized Biodiversity Value: a resilient area with high levels of plant and animal movement that is less concentrated than in a corridor with rare species population, exemplary natural community or intact habitats.
Climate Corridor with Coastal Migration Space: areas where marshes are likely to migrate with sea level rise that are resilient.

Resilient Secured: Land that is secured from conversion to development that is buffered from climate change because it contains many connected micro-climates.
Resilient Area with Recognized Biodiversity Value: A place buffered from climate change because it contains many connected micro-climates with rare species population, exemplary natural community or intact habitats.
