Muhasebe

Excerpt from Effect of Seedbed Condition on Regeneration of Virginia Pine After Logging The harvest removed all merchantable trees from the cut strips, and the remaining culls above 4 inches d.b.b. Were girdled and poisoned. Logs were skidded tree-length to roadside with a TD - 6 tractor and logging cart. It was esti mated that this operation exposed mineral soil on 15 to 30 percent of the area. In August 1953 the slash was broadcast burned; the fire consumed all of the light slash and, on about 60 percent of the area, at least some of the litter. Green brush and compact pine litter did not carry the fire. During the next 2 years, germination was tested on seedbeds created by the 1953 logging and slash-burning. The four strips were each divided lengthwise into three equal portions for separate sampling to determine whether shade or root competition from the uncut strip would influence germi nation and seedling survival. On each portion of each strip, three plots were established in November 1953, one each on undisturbed, disturbed, and burned seedbeds. This installa tion thus totaled 36 plots. In January 1955 a second set of 36 plots was established according to the same distribution, each plot being located within 25 feet of its 1953 counter part.
