Biodiversity Resources Center

Hudsonia’s Biodiversity Resources Center (BRC) is the umbrella for several major programs that promote the protection of species, habitats, and ecosystems by placing good biological information in the hands of agencies and individuals most involved with decisions pertaining to land development and conservation. BRC programs include the following:

Biodiversity Education Programs
The courses, workshops, and seminars of the Biodiversity Education Program instruct community leaders in science-based principles and techniques for biodiversity conservation. Through hands-on laboratory and field exercises, participants learn the value of biodiversity in their communities, how to recognize habitats of ecological significance, and how to protect important resources through sound planning and site design.

Habitat Mapping
The Biodiversity Resources Center’s Habitat Mapping Program carries out large (usually townwide) projects to identify and map habitats of special ecological importance. The purpose of these projects is to provide information to landowners, town agencies, and conservation NGOs about biological resources of conservation concern. Clinton_habitats_sm
Biodiversity Research
Hudsonia conducts biodiversity surveys and habitat assessments of sites throughout the Hudson Valley and neighboring regions at the request of public agencies, NGOs, and individuals. Depending on the need, these projects may entail general assessments of habitat presence and quality, or detailed surveys for particular species (or groups of species) of conservation concern. Otho_fieldwork
Our main specialties are vascular plants, butterflies and moths, reptiles, amphibians, fishes, and birds, but we bring in research associates with expertise in other groups of organisms when needed. In addition to original field research, we analyze new and existing data, and make recommendations for reducing the impacts of human activities on important species and habitats. IMG_2844
All BRC projects are designed to advance local knowledge of biological resources and enable planners, regulatory officials, landowners, and residents to recognize and protect important areas and stem the rapid loss of native biodiversity in the region.
