TY - Generic T1 - The influence of forest cover on snow melt T2 - 15th Annual Western Interstate Snow Survey Conference Y1 - 1947 A1 - Wilm, H.G. KW - Snowmelt research, Watershed management AB - There is presented a survey of important literature on the effect of forest cover on snow-melt, with recent results of investigations in the Fraser Experimental forest near Fraser, Colorado. It is shown that forest management, by selective cutting , influences greatly the accumulation and retention of snow on the ground. The evidence supports Dr. J.E. Church's Fir forest, possessing a maximum number of glades, as the most desirable type of snow conservation.Discussion by Walter U. Garstka points out the fact that forest management and watershed management must walk hand-in-hand to secure the optimum of water supplies, timing of runoff and timber products supplies, wood, lumber, paper, livestock grazing, power, flood control and irrigation.

KW - Forest management optimum water yield, Forest management timber cutting, Snowmelt AB - Experiments conducted in mature forest of lodgepole pine at Rocky Mountain Forest & Range Experiment Station in Colorado, show that planned cutting will increase the snow cover during the accumulation period. A total of 17.5 inches of water passed through the forest canopy on heavily cut-over plots, as compared with 13.33 inches in the un-cut forest. The accelerated melting rates of the cut-over plots were compensated by the excess snow stored initially. All experimental plots became bare at approximately the same time. Cutting is not advised in areas where floods and erosion are problems.

On the Fraser Experimental Forest, Colorado, a detailed experiment is being conducted to find out the effects of cutting mature lodgepole pine on various factors affecting water yield. Of these factors, soil moisture deficiencies are particularly graphic in showing the relative consumption of water by uncut and cut-over stands. One year’s data have been collected on soil moisture deficiencies; although the study will require several more years for completion, the methods and results are of sufficient utility to be worth current discussion. The experimental design and sampling procedures are discussed. Analysis of the first year records are shown along with text discussion of results and probable refinements to be made when further years of records are available.
