Abstract

Aspen stands sprayed with herbicides had higher numbers of aspen suckers than adjacent unsprayed stands. Understory production was higher due to more grass production in the sprayed stands. While the composition of forb species was lower, the number of grass species was higher on sprayed stands than on unsprayed stands. Vegetative cover was greater on the sprayed plots, but organic matter was deeper on the unsprayed plots. These results agree with expectations of broadleaf herbicide treatments.
