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.

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.

All BRC projects are designed to advance local knowledge of biological resources and enable citizens, planners, and regulatory officials to stem the rapid loss of native biodiversity in the region.
