Snow and Frost Conditions in New Hampshire, Under Hardwoods and Pines and in the Open
White pine and red pine plantations were comparable in snow depth, but a hardwood stand had a snow depth similar to that in an open field. Differences are attributed mainly to canopy density. Order of snow disappearance was: (1) open field, (2) hardwoods, (3) red pine, (4) white pine. Melt rates were .10, .05, and .04 inches per day for hardwoods, white pine, and red pine respectively. Concrete frost was extensive in the open field and under white pine; whereas at the maximum frost occurrence under red pine and hardwoods was 39 percent. Yearly fluctuations in temperature and snow depth can produce large variations in frost occurrence, particularly under conifers. Uniformly shallow frost--l.6 to 1.8 inches average--was found in all four cover types.
