Thousand Islands level year-round, and support at least two living trees. The Thousand Islands archipelago is located at the outlet of Lake Ontario at the head of the Saint Lawrence River. The region is bisected by the Canada–United States border and covers portions of Jefferson and St. Lawrence counties in the U.S. state of New York, in addition to parts of the United Counties of Leeds and Grenville and Frontenac County in the Canadian province of Ontario. Geologically, most of the islands are located where a branch of the Canadian Shield runs south across the river to join with the Adirondacks. The
Thousand Islands (Cocoa Beach) 2006 with acquisition of the Reynolds tract, and were completed in 2007 with acquisition of the Crawford Homes tract by the Brevard County Environmentally Endangered Lands Program (EEL). Restoration efforts involve removal of Brazilian pepper and Australian pine. Despite the Category I status of Australian pine, removal of trees in ecological restoration can be controversial among the lay public. In the EEL-managed Thousand Islands Conservation Area, replanting has been used following removal of Australian pine, but the effects are modest, with native recruitment out-pacing planted species. The management plan for the north Thousand Islands is currently (April 2013) under revision.
