If this sounds like ecology, then it can be stated accurately that silvics is the ecology of the forest. Silviculture involves managing and handling the forest in view of its silvics. Silviculture imitates a natural change-such as a windthrow, beetle infestation, or fire.However, silvicultural methods harvest forest products for human use rather than wait on nature to burn them, eat them, or blow them down.ilvics involves understanding how trees grow, reproduce, and respond to environmental changes. Some tree species thrive in shade-sugar maple, red maple, hemlock and basswood are good examples. These species can live, grow, and reproduce in shade and semishade conditions.
