- Description:
- Four conifer species growing on three different duff depths on burned and unburned seedbeds were examined for germination, survival, and height and diameter growth after three years. Total above-ground biomass and number of trees also are reported. Douglas-fir (Psuedotsuga menziesii var glauca (Beissn.) Franco), ponderosa pine (Pinus ponderosa Dougl. ex Laws.), western larch (Larix occidentalis Nutt.), and western white pine (Pinus monticola Dougl.) were examined on a Thuja plicata/Clintonia uniflora-Clintonia uniflora habitat type (Cooper and others 1987) in Northern Idaho. Germination was greater on mineral soil seedbeds and the three burned seedbeds. Within the burned seedbeds, germination increased as duff decreased. The same trends were true for seedling establishment. Therefore, on burned and unburned seedbeds natural regeneration increased proportionally with decreasing duff thickness. At the end of the third growing season total height and basal diameter were recorded. Significant differences appeared between burned and unburned seedbeds, as well as differences between duff thicknesses for all species. Analysis of total above-ground coniferous biomass and number of trees showed significant differences between duff thickness, but not between burned and unburned seedbeds. This study’s results are similar to general trends reported for germination, survival and height in previous studies. The magnitude of some differences for burned and unburned seedbeds separated by duff thicknesses was greater than expected
