Foothill Associates develops biological and wetland resource information for projects ranging in size from small individual sites to regional, large-scale multi-jurisdictional planning areas. The baseline information our biologists gather includes identification and mapping of wetlands, vegetation, and wildlife habitats — including those with the potential to support rare, threatened, or endangered species.
We conduct rare plant surveys and floristic inventories, wetland delineations, and certified arborist surveys — including oak tree inventories and riparian woodland surveys.
