This dataset represents current terrestrial intactness values (estimated at the 1km level) within the modeled distribution of the Arroyo toad (Anaxyrus (Bufo) californicus). Terrestrial intactness is high in areas where development is low, vegetation intactness is high, and fragmentation is low. Consequently, this dataset serves as a general* indication of habitat quality within the distribution of this conservation element.Estimates of current terrestrial intactness were generated by an EEMS fuzzy logic model that integrates multiple measures of landscape development and vegetation intactness, including agriculture development (from LANDFIRE EVT v1.1), urban development (from LANDFIRE EVT v1.1 and NLCD Impervious...
These data identify the areas (in general) of critical habitat designated for the arroyo toad. NOTE: THIS DATA SET INCLUDES APPROXIMATELY 900 ACRES OF LAND INADVERTENTLY OMMITTED FROM THE MAPS AND LEGAL DESCRIPTIONS FOR UNITS 8, 10, 11, AND 14 IN THE FINAL RULE PUBLISHED ON FEBRUARY 9, 2011 (76FR7246). UNTIL A CORRECTION OF THE FINAL RULE IS PUBLISHED THE BOUNDARIES OF UNITS 8, 10, 11 AND 14 SHOULD BE CONSIDERED PROVISIONAL. These data reflect revisions to the proposal published in the Federal Register on October 13, 2009 (74FR52614). Critical habitat for the species consists of approximately 98,000 acres among 22 units from San Diego County northward to Santa Barbara County, California. Descriptions of the units...
Expert model output identifying the species distribution of the arroyo toad (Anaxyrus (Bufo) californicus) in the DRECP region. Dudek's original proxy model, (areas within 1 km of the Mojave River upstream of Oro Grande), was updated by CBI to include all areas within 1 km of stream reaches with current extant toad observations, based on CNDDB and Dudek compiled datasets.
