WILTON, N.Y. — Officials say they plan to expand an upstate New York habitat for the federally endangered Karner blue butterfly by 68 acres.
Nature Conservancy officials announced they purchased property within the Wilton Wildlife Preserve and Park in Wilton, N.Y. for the butterflies. The property will extend 125 acres of habitat serving as an incubator for the Karner blues, which were classified by writer Vladimir Nabokov in 1941.
The Nature Conservancy announced the $265,000 purchase last week.
More than 20,000 of the butterflies live in the Wilton area, making it the largest population on the East Coast.
The species has disappeared from many of its native homes. New Hampshire and Michigan have undertaken efforts to protect and restore them.
The butterfly was placed on the federal endangered species list in 1992.
