This data set includes Biodiversity 3 PCAs, Level 2 and 3 buffer areas, and the study region. Buffer polygons are areas where multiple one-mile buffers for a given PCA overlap. Level 2 provides a buffer for two PCAs and Level 3 provides a buffer for three PCAs. Buffer poylgons are categorized based on the extent conservation easements fall within them. These buffers are important conservation areas because they create wildlife corridors between multiple PCA habitats. 

Potential Conservation Areas (PCAs) are “land areas that can provide the habitat and ecological processes upon which a particular element (i.e. rare plant and animal species and significant plant communities) occurrence, or suite of element occurrences, depends for its continued existence”. PCA boundaries are determined by county-wide biological assessments conducted by the Colorado Natural Heritage Program. PCAs are ranked according to their biodiversity significance, ranging from 1 (greatest) to 5 (least). This study only analyzed categories 1 to 3.

CEs from six land trusts in Boulder, Douglas, and Jefferson Counties were analyzed.  The buffer percentage for a Buffer is based on the following criteria: very high (>80%), high (60-80%), medium (40-60%), low (20-40%), and very low (<20%).
