This includes walnuts, oaks, hickories, and other nut-bearing trees that are very beneficial to wildlife. TSI can also promote the growth of grasses, weeds, and shrubs that provide food and cover for rabbits, rodents, and songbirds. Seedlings of species that don't require much sunlight are the most likely to grow after individual trees are cut. Examples include green ash, elm, and beech trees. Impacts on wildlife are usually neutral.
Group selection removes patches of trees one-quarter to two acres in size.
This approach is more likely to benefit species like oaks than single tree selection. A few of the old, poor-quality trees should be left as den sites for wildlife. Some logs can be left on the ground to make homes for animals like salamanders, and branches can be trimmed to make brushpiles. Seedlings that need some direct sunlight are the most likely to benefit. Examples include red maple, silver maple, white oak, black oak, northern and southern red oaks, and bur oak.
