In other words, forests provide a multiplicity of human benefits, including natural beauty, which continue to grow in number and importance. More knowledge is needed about forest ecosystems so they can be better protected and managed and the yields of the resources they provide are sustained. Northwestern Indiana was a complex ecosystem of tall-grass prairie, wetlands, and scattered woodlands, most of which was converted to agricultural use. Prairie and wetland ecosystems provide many human benefits and should be better understood so the areas remaining can be protected and studied. Hence, the Department of Forestry and Natural Resources includes among its activities, study of interrelationships among prairie and wetland organisms and their biotic and abiotic environments.
Wood requires comparatively little energy to convert it into many useful products.
Consequently, the environmental impacts of the production of wood products are usually less than substitute products made from other raw materials such as aluminum, cement, plastic, and steel. In addition, substantial accomplishments have been made in wood science and engineering, especially during the last 50 years, in increasing the efficiency with which wood products are produced and developing new products that require less wood. Indeed, more unit of product output can be produced today per unit of wood input than ever before, effectively extending the nation's timber supply. Thus, responsible use of wood products and wood science and engineering contribute in a significant way to achieving a quality environment, including healthy, sustainable forests. A goal is a statement of intention to achieve a specified result compatible with the mission of the department.
