This image shows District Conservationist Cliff Marcus taking a core sample of a birch tree to determine the age of the trees growing in the area. The cross-section sample extracted from the tree with the coring tool exposes the annual growth rings which are counted to determine the age of the tree. The stand of trees in view appears to be a mixture of birch and spruce with most of the birch trees being younger than the one Cliff is aging.
