A Pilot Planting Trial on a Southwestern Idaho Deer Winter Range

摘要

The planting compared: (1) two browse species--antelope bitterbrush Purshia tridentata and wedgeleaf ceanothus Ceanothus cuneatus; (2) two planting methods--direct seeding and transplanting; and (3) two bitterbrush seed sources--southwestern Idaho and northwestern Nevada. Overall, the seeding treatments had a sixth-year survival of 80 percent; transplanting treatments had a sixth-year survival of 62 percent. Bitterbrush from local seed sources, whether seeded or transplanted, outperformed other plants significantly in survival and nonsignificantly in height growth.
