Many people confuse the role of the forester with that of the logger, but most foresters are concerned not only with the harvest of timber, but also with the sustainable management of forests to (in the words of Gifford Pinchot) "provide the greatest good for the greatest number in the long term". Another notable forester, Jack C. Westoby, remarked that "forestry is concerned not with trees, but with how trees can serve people". The median salary of foresters in the United States in 2008 was $53,750. Beginning foresters with bachelor's degrees make considerably less. Those with master's degrees are able to command salaries closer to the average. The Council for Higher Education Accreditation considers the Society of American Foresters as the principle accreditor for academic degree programs in professional forestry, both at a Bachelor's and Master's level.
