    Description

    Species composition and site index were determined on nine tree habitats in an area of schistose drift and compared with previous findings on habitats with granitic drift. Habitats on schistose drift supported more sugar maple and had somewhat higher site indexes. Compact tills in schistose drift supported northern hardwoods, and the site indexes for yellow birch were 66 to 71 feet. Compact tills in granitic drift supported softwood-hardwood mixtures and had a softwood climax; the site indexes for yellow birch were 56 to 57 feet. Species composition and site index for a given habitat may vary between glacial drifts with different mineralogies.
