Audubon California 20081201 vector digital data ftp://ftp.dfg.ca.gov/BDB/GIS/BIOS/Public_Datasets/400_499/ds485.zip http://bios.dfg.ca.gov The objective of this project was to digitally map the boundaries of Audubon California's Important Bird Areas (IBA). Existing Important Bird Areas identify critical terrestrial and inland water habitats for avifauna, in particular, habitat that supports rare, threatened or endangered birds and/or exceptionally large congregations of shorebirds and/or waterfowl. The digitization of Important Bird Areas represents an important first step in conservation planning of these critical habitats using GIS. As of October 2007, a draft layer of all 148 Important Bird Areas in California was completed. Currently, a review is in progress with Audubon Chapters and local experts, with a final version completed by Nov. 1, 2008. The final map and data will be released to the public in November, 2008.

IBA_Name_Subregion For Important Bird Areas with multiple polygons, this field names the subarea, such as a lake or mountain. Region Region of California, as defined in IBA book - 8 regions total Audubon_Conservation_Status Audubon California Important Bird Areas conservation status. High Priority Important Bird Areas are those sites considered highest priority for conservation actions based on analysis of biological value, threats, and conservation opportunities. Those labeled as "Slated for Conservation Action" will receive conservation work by Audubon California and/or Audubon chapters over next 5 years. IBA_Status Level of significance for an Important Bird Area. Global Continental State ShareTheShore Share our Shores program sites managed by Audubon California and Audubon chapters. CoastalRestoration Coastal restoration sites managed by Audubon California. P_Criteria Criteria for Important Bird Areas designation; P=>10% of CA/1% global population of one of more sensitive taxa. L_Criteria Criteria for Important Bird Areas designation; L=>9 sensitive species. S_Criteria Criteria for Important Bird Areas designation; S=>10,000 possible in 1-day count. W_Criteria Criteria for Important Bird Areas designation; W=>5,000 waterfowl in 1-day count. Accuracy_Map Scale of 1-3 based on confidence in accuracy of polygon boundaries. 1 Low accuracy, location found but text description inadequate - map needs refinement, better description of boundaries; usually site not well known, remote, or covering vast area. 2 Moderate accuracy, map boundaries moderately accurate based on description in book but may need additional local review for at least some of the boundary. 3 High accuracy, boundaries usually based on discrete areas such as NWR boundary, DOD property, well defined water body, islands, etc. or received considerable local expert review. Scale Map Scale. Generally urban areas were mapped at 1:10,000; most areas were mapped at 1:24,000. Some large areas mapped at 1:100,000. No areas were mapped at less than 1:6,000.
