The importance of disturbance and land-use history in New England: implications for forested landscar extent and magnitude are necessary to maintain forested ecosystems and their faunal components. An understanding of the background rates and causes of change in forested landscapes can help to guide conservation efforts on many scales.

Changes in global forest distributionrthern hemisphere to the moist and dry forests of tropical latitudes. Such a variety of ecosystems, that collectively cover roughly 39% of the world’s land surface (WCMC, 1992), is the key to the global diversity of life.

The status of forested wetlands and waterbird conservation in North and Central America Gosselink, 1986; Bacon, 1990). Nonetheless, forested wetlands provide habitat for an exceedingly diverse array of fish and wildlife resources throughout the world, especially in the tropics (Lugo and Snedaker, 1974; UNESCO, 1978).

Bird community dynamics in boreal forestscandia, Siberia, Alaska and northwestern Canada). Although taiga may be considered relatively uniform, there is marked variation due to climatic differences. This has resulted in various subdivisions of the boreal zone (e.g. Hare, 1954). The yearly mean temperature is about 0°C; winter is long and cold, and the environment is highly seasonal.
