    Description

    Nitrogen and phosphorus were applied to young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) trees to determine their effects on deer browsing and tree growth. Nitrogen (N) proauced measurable responses in browsing of terminal shoots and growth of trees the first year, but effects were mostly negligible 2 years after treatments. No responses to phosphorus (P) were detected. Nitrogen and N+P treatments increased the concentration of N in tree foliage the first year, but amount of moisture, ash, calcium, and P were not affected after 2 years.
