We must enhance the effectiveness ofland stewardship and management of the world's natural resources to meet a growing global population's need for conservation, sustainable development, and use of land, water, and other natural resources. Ecosystem-based, mul tiple-use land stewardship is necessary when considering the present and future uses ofland, water, and other natural resources on an operationally efficient scale. We need holistically planned and carefully implemented watershed management practices, projects, and pro grams to accommodate the increasing demand for commodities and...

A comprehensive exploration of the effects of fires--in forests and other environments--on soils, watersheds, vegetation, air and cultural resources.

Best known for its cactus-studded deserts and the awe-inspiring Grand Canyon, Arizona boasts even more natural features that surprise visitors and continue to amaze longtime residents. Using C. H.

The effectiveness of land stewardship must be enhanced to meet a growing population's need for conservation, sustainable development, and use of natural resources. Ecosystem-based, multiple-use oriented land stewardship is necessary when considering the present and future uses of land, water, and other natural resources on an operationally efficient scale. Holistically planned and carefully implemented watershed management practices and programs will always be needed to meet the increasing demands for commodities and amenities, clear water, open space, and uncluttered landscapes.
