Silviculture, from the Latin term, silva, (meaning forest or woodland) is often described as the art and science of forest cultivation. With a desired forest condition or objective in mind, silviculturists manage tree density and composition through harvest, reforestation, and other stand treatments. Silviculture treatments can be used to create conditions for optimal timber production, accelerate structural diversity for wildlife habitat, enhance forest health and even promote old-growth characteristics. Silvicultural research on the OSU Research Forests include both short- and long-term studies; the latter involving measurements taken over decades with some still ongoing. Researchers test new and innovative practices and analyze tree and forest responses which are published in scientific journal articles. The research conducted here on the Research Forests helps inform and improve forest management on private, county, state, federal and tribal lands.
