Description: Thinning is one of our most important ways to influence tree and stand development. The objectives may include increasing the volume, size, and quality of wood produced from a forest and developing particular stand structures and characteristics for other values, such as wildlife or aesthetics.

The Levels-of-Growing-Stock (LOGS) Cooperative was initiated in the early 1960s, stretching from Southern Oregon through Washington to Vancouver Island, B.C. The study was designed to provide information on the relation between tree and stand growth, and thinning treatments, as a basis for managing young Douglas-fir stands for efficient investment in timber production.

Although the cooperative continues to provide this information, the long-term research is also providing valuable information on how to design regimes to meet a wider range of stand management objectives. Wildlife, aesthetics, and carbon storage have become prominent questions.
