Ten-Year Response of Western Larch and Douglas-fir Seedlings to Mulch Mats, Sulfometuron, and Shade in Northeast Oregon

This trial investigated the effectiveness of small-scale vegetation management treatments on seedling survival and growth. Treatments included a black mulch mat, a spot application of sulfometuron, and control; in each of these treatments, half the seedlings were shaded. Costs of the treatments were...

Summary:This trial investigated the effectiveness of small-scale vegetation management treatments on seedling survival and growth. Treatments included a black mulch mat, a spot application of sulfometuron, and control; in each of these treatments, half the seedlings were shaded. Costs of the treatments were evaluated. Vegetation management and shade improved seedling survival after 4 and 10 yr. After 10 yr, individual seedling and per-area volume growth in the weed control treatments outperformed the control; in some cases, they were diverging. Lowest cost per established seedling was obtained by using sulfometuron without shade.
