Dave Hartesveldt, B.A.
Principal
Senior Botanist and Wetland Scientist

Mr. Hartesveldt oversees issues relating to the botanical and wetland resources for projects. He is an experienced botanist and wetlands ecologist who has been studying the flora of California for much of his life. Although his particular interest is the flora of California, he has studied regional floras in Oregon and Minnesota, states in which he worked as a seasonal ranger for the National Park Service. He has provided consulting services to a variety of clients including local agencies, planning firms, attorneys, and developers. Mr. Hartesveldt has completed specialized training in wetland delineation methodologies, and during the past 15 years, he has completed more than 300 wetland delineations. He has conducted studies in tidal marshes, diked salt marshes, freshwater marshes, ruderal seasonal wetlands, alkali wetlands, vernal pools, and montane meadows. Mr. Hartesveldt has conducted numerous surveys for threatened or endangered plants and animals, and/or their habitats, and assisted his clients with mitigation that reduced impacts to such species. Mr. Hartesveldt possesses extensive experience in establishing conservation easements throughout California, especially throughout San Joaquin Valley and Madera and Fresno Counties. He has also prepared portions of over 800 Environmental Impact Reports, initial studies, and NEPA documents requiring wetland delineations, special status species surveys, habitat mapping, etc. As a project manager for many of these projects, he has supervised interdisciplinary teams of biologists characterizing the biological setting of project sites and planning areas, determining project impacts, and developing conceptual mitigation plans consistent with the requirements of CEQA and NEPA.
