Silvicultural chemicals are critical tools to maintain and improve stand productivity on private, working forests. However, chemical use continues to be scrutinized, particularly within a sustainable forestry context.
Strengthening the body of technical information related to silvicultural chemicals and intensive management enables Member Companies to more effectively meet economic goals while maintaining high environmental standards.
Silvicultural Chemicals
Using herbicides for forest vegetation management is an important tool on private, working forests. Various other silvicultural chemicals (insecticides, fertilizers) are also important management tools. However, timber managers who wish to include silvicultural chemical use as a component of their management plans are increasingly faced with questions, concerns, and opposition.

Although recent field studies have shown that concentrations of herbicides in streams are low following applications made when modern best management practices (BMPs), some data gaps have been identified. In particular, data showing duration of elevated herbicide concentrations immediately preceding and following storm events are lacking.
