Scientific research in the Forest Service puts theory into practice. Many of the original employees of the agency were scientists, working in laboratories, nurseries, and experimental forests. Their work enhanced the agency's knowledge and understanding of fire, the effects of grazing, seed dispersal, wood characteristics, and tree growth. Forest Service scientists have improved methods for turpentining, forecasting fire danger, building homes, and recycling wood. They have also contributed to our understanding of forest and wildlife ecology.
