Habitat Assessment Field Protocol: South County Grasslands Project

Type: protocol

Article abstract: Detailed habitat assessments were conducted by CBI, TNC, and SDSU within the four designated South County grassland management planning units: Sweetwater Reservoir, Proctor Valley, Rancho Jamul Ecological Reserve, and Sycamore Canyon (Figure 1). All four units were assessed in 2011; additional assessments were conducted in 2012 at Rancho Jamul Ecological Reserve and Sycamore Canyon. The purpose of these assessments was to document existing habitat conditions and determine habitat suitability for the three target species (burrowing owl, Otay tarplant, and Quino checkerspot butterfly), as well as threats, results of past management actions, and potential management and restoration actions. Data from the habitat assessments were used to identify and prioritize species-specific management actions within each of the four planning areas. In addition, these data were used to identify preliminary vegetation associations, as well as potential restoration sites for native grasslands and forblands. Prior to conducting fieldwork, CBI and TNC reviewed soil maps, aerial photographs, and results of previous vegetation mapping, and plant and wildlife surveys in the project areas and vicinity.
