The League of Women Voters of Lexington will host a forum Friday about the town’s large amount of conservation land and how it is cared for. Members of the Conservation Commission and town staff will discuss Lexington’s 1,400 acres of conservation land, representing 12 percent of its total area. The discussion will touch on the history of the conservation land, how it was acquired and cared for, and how it will be promoted and protected in the future. The discussion is the first in this season’s First Friday Forums series, hosted by the League of Women Voters to promote awareness and understanding of public policy. The free session will begin at 9:30 a.m.  in the community meeting room on the lower level of Cary Memorial Library.
