Members of The American Chestnut Foundation cover chestnut seeds planted Thursday, in a lot managed by the Small Woodlot Owners Association of Maine, on Case Road in Winthrop. The volunteers and staffers of the non-profit group planted 900 chestnut seeds as part of the group’s effort to plant a total of 3,600 in four different seed orchards managed by SWOAM in Winthrop, according to Maine chapter vice president Eric Evans. The American Chestnut Foundation was started in 1983 to reverse the decline of the hard wood tree species.
