reintroduction

Peter Lesica's work to reintroduce an endangered prairie plant may or may not prove successful, but he’s attempting to reverse the decline of an inconspicuous Palouse Prairie flower – Spalding’s catchfly (Silene spaldingii). Five years of preparation led up to the planting.

Scientists argue that the small, isolated herds of Bison bison now dotting the west could be reintroduced to vast swaths of their former range, including sites in Montana, Wyoming, Colorado and New Mexico.

They could come from Yellowstone.
