Summary

To analyze the impact of scale effects on conservation planning by analyzing conservation networks at local and regional scales.

Description

UC Davis ecologists compared conservation networks at regional and local scales from the same area within the central valley of California to analyze the impact of scale effects on conservation planning. This could help determine if an intersection of results from multiple scales can potentially be used to prioritize areas for conservation found to be important at several spatial scales. Using MARXAN and least corridor analysis technologies, potential regional amd intraregional conservation networks were compared. Large differences arose, specifically in the disparateness of the identified corridors that connect core reserves.

Lineage

Lineage statement
BDB employees combined the two shapefiles 'CV_cores_2000' and 'cv_all_coor' into one shapefile 'Cooridors_and_CoreReserves_Tbl_Modified'. BDB employees also added the field 'Type' in the attribute table in order to distinguish if the record is a cooridor or a core reserve.
