Current Zonation Prioritization for California Land Birds

Zonation conservation rankings based on species distribution models for 198 land bird species under current (1971-2000) climate conditions. Zonation is a spatial conservation planning software tool that can take into account multiple species to create a hierarchical prioritization of the landscape. This is in contrast to other spatial conservation planning tools which may require predefined conservation targets or areas. Here, we used 199 California landbirds along with Zonation's "core-area" algorithm to prioritize the California landscape. Species were weighted according to the California Bird Species of Special Concern criteria and probability of occurrence was discounted by distribution model and climate model uncertainty surfaces. This layer shows priority areas for the current period.
