    Description: This study examined whether tree seedling establishment patterns could account for the abrupt boundary between northern hardwood and boreal forests that exists in the Lake Superior Provincial Park area of north central Ontario. The establishment patterns of the two dominant tree species in the northern hardwood forest: sugar maple and yellow birch, and of the two dominant tree species in the boreal forest: balsam fir and white spruce, were studied. It was hypothesized that hardwood seedlings regenerated best in the micro-environments of the northern hardwood forest type, and that coniferous seedlings regenerated best in the micro-environments of the boreal forest type, so that each community remained distinct from the other. The micro-environments were interconnected; decomposed litter depth increased with increasing hardwood leaf-litter mass, and both decreased with increasing moss cover mass and increasing light levels received. Sugar maple seedlings were found growing in the deepest...
