Silviculture is the art and science of managing forests for specific objectives.

Silvicultural practices manipulate forest vegetation through prescriptions to fulfill various objectives such as sustaining wildlife habitat, maintaining hydrological processes, restoring ecosystems, conserving biodiversity, and producing wood products. Depending on the objective, silviculture is the specialty that incorporates the concepts and principles from many scientific disciplines (soils, ecology, wildlife, modeling, economics).

Here in the UK help to control grey squirrels can be acheived by manipulating the crop by thinning, natural regeneration, shade bearing species and growing trees that are less attractive to grey squirrels like ash, wild cherry, small leaved lime and holly.
