Alternate Types of Artificial Shade Increase Survival of Douglas-Fir (Pseudotsuga menziesii (Mirb.) Franco) Seedlings in Clearcuts

Survival of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings on two sites facing south was increased by three artificial shading devices: shadecards to the south of the seedlings, shadecards to the east of the seedlings, and Styrofoam cups inverted around seedling bases. Shadecards placed to the south of the seedlings increased survival the most, but the cups also increased survival and were cheaper. On one site, deer did not browse the seedlings; but on the other site, seedlings with shadecards were browsed less than either the controls or the seedlings with cups.
