The High Branch mission is to optimize the value of open space by providing wildlife knowledge, conservation leadership, and strategic communication to organizations and individuals. We use a variety of scientific and collaborative approaches to achieve our clients’ objectives. In addition, we tell stories about people, nature, and place in order to strengthen support for conservation.

High Branch serves conservation organizations and natural resource agencies in the Northeast and adjacent regions. We also advise landowners, foresters, and farmers on wildlife-friendly management practices.
