The Forester's Dilemma : Paradoxes In The Criteria And Indicators For Sustainable Forestry, Theodore E. Howard
The Forester's Dilemma : Paradoxes In The Criteria And Indicators For Sustainable Forestry, Theodore E. Howard
New Hampshire Agricultural Experiment Station Publications
Since sustainable forestry is a complex endeavor, paradoxes naturally exist in the certification criteria and indicators. There are different ways to establish the sustainability horizon and alternative harvest profiles that, although sustainable, may not meet specific criteria. The application of historic range of variation data and criteria must confront issues of time and spatial scales as well as how much human disturbance is natural. Defining “local” in the bioregional context is important for addressing socioeconomic criteria. The forester’s ability to deal with the self-contradictions in the criteria and indicators of sustainable forestry will improve with experience in the certification process.

We studied the effects of forest fragmentation on southern flying squirrels (Glaucomys volans) in southern Illinois, and examined factors influencing nest box use. Ten nest boxes were placed in each of 30 oak-hickory forest fragments. Nest boxes were checked monthly after installation. We measured habitat variables that described the nest box tree, the microhabitat surrounding the nest box tree, and landscape level characteristics of the fragments (isolation and area). Overall, 78% of the 300 nest boxes were used. Glaucomys volans was captured in 24 of the 30 forest fragments, and evidence of squirrel use was found in 4 additional fragments. …
