The objective of this project, covering the Puget Lowland and Willamette Valley ecoregions within Washington state, was to create a unified digital map of: (1) untilled grasslands now existing in landscapes that formerly supported native dry grasslands, and (2) oak dominated or co-dominated canopies. The map's scale and level of detail are designed to be appropriate for both regional-level conservation planning and county-level planning and development screening. Native grasslands and oak woodlands are some of the most imperiled ecosystems in western Washington (Dunn and Ewing 1997). For example, native grasslands in the south Puget Sound area have declined to less than 3% of their pre-settlement areal extent (Crawford...

The dataset consists of abundance information of butterfly species (61 species) collected at 25 sites in northwest Indiana in 1998 and 1999. Each site was surveyed 21 times. Auxiliary data on environmental conditions were collected to allow us to relate habitat differences among sites to differences in abundance and composition of the butterfly community.
Why Rangelands: The Central Valley of California, the surrounding foothills and the interior Coast Range include over 18 million acres of grassland. Most of this land is privately owned and managed for livestock production. Because grasslands are found in some of California’s fastest-growing counties, they are severely threatened by land conversion and development. In addition climate change stresses grasslands by potentially changing water availability and species distributions.Maintaining a ranching landscape can greatly support biodiversity conservation in the California Landscape Conservation Cooperative (LCC) region. In addition ranches generate multiple ecosystem services—defined as human benefits provided...
