Discover how new technologies are revolutionizing large landscape conservation in the first installment of Mt.

Recognizing this urgent need, conservationists have built partnerships that leverage technology, funding, and land conservation to save rare plants on a landscape scale. Using case studies, Joel Dunn, President and CEO of Chesapeake Conservancy, will discuss “internet age” technology and partnerships that have revolutionized the conservation movement.
