The Use of Tree Shelters with Northern Red Oak Natural Regeneration in Southern New England
Abstract:The use of tree shelters with naturally established red oak seedlings was studied in southern New England mixed-hardwood stands where deer browsing limited regeneration height growth. Seedlings of three size classes (basal diameters of 5 mm, 8 mm, and 15 mm) were cut off just above ground level during the dormant season to induce sprouting. Plastic tree shelters were placed over one group in each size class; another group was left without shelters but was protected from deer browsing by fencing. In the first growing season, seedling sprouts inside shelters in the two larger size classes had double the height growth (with some terminals growing out of the 150-cm tall shelters) but less diameter growth, compared to sprouts outside shelters. The height difference was maintained but not increased over the next 2 growing seasons. Height growth for sprouts from the smaller size class was not increased by shelters. The use of tree shelters with large diameter seedlings stunted by browsing may have potential for ensuring successful red oak regeneration without the costs of planting. North. J. Appl. For. 9(4):141-145.
