Natural Landscape Blocks - dissected by major and secondary roads - in California, USA

Resource Abstract:
The California Department of Transportation (Caltrans) and California Department of Fish and Game (CDFG) commissioned the
California Essential Habitat Connectivity Project because a functional network of connected wildlands is essential to the
continued support of California's diverse natural communities in the face of human development and climate change. The Essential
Connectivity Map depicts large, relatively natural habitat blocks that support native biodiversity (Natural Landscape Blocks)
and areas essential for ecological connectivity between them (Essential Connectivity Areas). This coarse-scale map was based
primarily on the concept of ecological integrity, rather than the needs of particular species. Essential Connectivity Areas
are placeholder polygons that can inform land-planning efforts, but that should eventually be replaced by more detailed Linkage
Designs, developed at finer resolution based on the needs of particular species and ecological processes. It is important
to recognize that even areas outside of Natural Landscape Blocks and Essential Connectivity Areas support important ecological
values that should not be "written off" as lacking conservation value. Furthermore, because the Essential Habitat
Connectivity Map was created at the statewide scale, based on available statewide data layers, and ignored Natural Landscape
Blocks smaller than 2,000 acres squared, it has errors of omission that should be addressed at regional and local scales.
