The responses of forest trees to chronic (NH4)2SO4 additions were examined at the Bear Brook Watershed in Maine, a paired watershed study designed to assess responses to chronic additions of acidifying substances. Responses evaluated included (1) foliar chemistry of hardwoods and re spruce; (2) nutrient resorption dynamics of hardwoods; (3) wood production and relative density in red spruce; and (4) the development of frost hardiness in red spruce.
