The status of forested wetlands and waterbird conservation in North and Central America
Chapter
Abstract
Forested wetlands represent one of the more prominent yet least understood ecosystems in the world (Lugo et al., 1990). These wetlands have been studied less than most other systems primarily because of their inaccessibility and aversion (e.g. noxious insects and poisonous reptiles) to humans (Mitsch and 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).
