The Bear Brook Watershed in Maine is paired watershed system; one watershed has been acidified bimonthly with granular ammonium sulfate since 1989. The adjacent watershed is used as a reference. The acid deposition treatment presents unique opportunities to look at the long-term affects of acidification on vegetation. This acid deposition treatment presents unique opportunities to look at the long tern affects of acidification on vegetation. In this text we review sugar maple ecology and their response to forest acidification, we investigate the response of sugar maple saplings to chronic N and S deposition, and we compare foliar nutrients of three size classes of sugar maple at BBWM.
