Justin Davilla, M.S.
Senior Ecologist/GIS Manager
Mr. Davilla has worked as a biological consultant since his graduation from California Polytechnic State University, San Luis Obispo, cum laude, in 2001. He also received a Masters degree from U.C. Berkeley in Range Ecology and Management in 2007.
As a botanist with EcoSystems West, Mr. Davilla has performed numerous biotic assessments, rare plant surveys, habitat characterizations, and invasive weed survey and eradication efforts. He has monitored development contractors for compliance with local, state and federal regulations and completed jurisdictional determinations of wetlands and waters of the U.S. using Army Corps of Engineers and California Coastal Commission guidelines. Mr. Davilla is also responsible for managing GIS databases and spatial information using ArcGIS software. He has developed detailed maps of biological resources and is proficient with GIS analysis tools including the manipulation of aerial imagery and data in both raster and vector formats.
Mr. Davilla has monitored wetland/riparian mitigation measures in preserves and habitat conservation areas, and conducted monitoring and surveys for special-status wildlife species. He has prepared applications for Clean Water Act Section 401 and 404 permits, CDFG 1600 series Streambed Alteration Agreements, and composed mitigation and monitoring plans required by these permits. Other relevant projects include a study conducted in 2005 on the affects of a roadside fire in Napa County on native vernal pools species including federally endangered Contra Costa goldfields, and monitoring federally threatened Bay checkerspot butterfly populations in South Bay serpentine grasslands.
As a graduate student researcher in the UC Berkeley Rangeland Ecology Laboratory, Mr. Davilla investigated the relationship between biotic and abiotic factors affecting the distribution and abundance of Italian thistle in blue oak hardwood rangelands. He was also responsible for managing a long term Net Primary Productivity (NPP) study at the UC Sierra Research and Extension Center and assisted with a long term vegetation monitoring project within several parks managed by the East Bay Regional Park District. Mr. Davilla provided support with data analysis using various statistical programs and created maps and predictive models using ArcGIS software.
Mr. Davilla also worked as a biological technician for the U.S. Forest Service in the Plumas National Forest. In this capacity, he conducted extensive botanical surveys, mapped target species populations and habitats using resource grade GPS, and composed survey reports for use in preparing Biological Evaluations, Environmental Assessments, and Environmental Impact Statements.
