Abstract
  • At three sites in southwest Oregon, uniform stands of whiteleaf manzanita were created for future studies on the effects of manzanita competition on Douglas-fir and ponderosa pine plantations. The sites were marked according to grids and nearby 2-year-old seedlings were lifted and transplanted to fill in gaps in the natural stands. Some plots were treated with a mixture of simazine, glyphosate, and 2,4-D to control weeds, and some were left untreated. After one year, survival of natural seedlings that were not transplanted was 98.0 and 95.3 percent on treated and untreated plots. Survival of transplanted seedlings was 66 and 92 percent on treated and untreated plots. Residual herbicides in the soil may have decreased the survival of transplanted seedlings. A uniform stocking of manzanita can be achieved by transplanting natural seedlings and controlling weeds with a minimum amount of herbicides.
