Paper Birch Regeneration on Scarified Logged Areas in Southcentral Alaska
Density and growth of naturally regenerated paper birch seedlings were examined in relation to substrate and vegetative competition on two scarified logged sites on the Matanuska Valley Moose Range in southcentral Alaska. Seedling density was inversely related to extent of thick O horizon, grass cover, herb cover, distance to the nearest seed tree, and the extent of B horizon substrate, and positively related to seedling density and the extent of A horizon and moss cover. Paper birch seedlings did not establish on organic layers more than 2 cm thick. Paper birch seedlings grew much more rapidly on the edges of scarified areas or on A horizon substrate than on B horizon substrate. The principal recommendation is that scarification should remove the organic layer and expose the A horizon, but should not be so deep as to expose the B horizon. North. J. Appl. For. 9(2):63-66.
