Wild Collection and Propagation of Rare and Endangered Plants
In Massachusetts alone, plants make up more than half of the total native species that are officially considered Endangered, Threatened, and Rare. In this talk, we will focus on how ex-situ plant conservation, coordinated plant collection efforts, and plant propagation play vital roles in preserving biodiversity and slowing the deleterious effects of climate change. We will discuss how collection trips are planned—and how citizen science now plays a role in these efforts—while providing a behind-the-scenes look at the planning process. A large focus will be plant propagation techniques such as seeds, cuttings, and grafting, and how these fit into various strategies for plant conservation.
