HELIX Environmental Planning (HELIX) conducted studies to assess effects of the Witch Fire on the 21,000-acre Rancho Guejito property located in San Diego County. The ranch includes thousands of acres of native habitats, including some of the largest intact Englemann oak groves in San Diego County. HELIX conducted botanical field surveys, assessed fire-induced changes to the habitat, and provided cost estimates for tree replacement and restoration. HELIX provided as-needed support for fire related litigation, including expert witness testimony, GIS maps and analysis, and biological studies
