1. The South and Middle American tropics contain the world's largest area of moist savanna. Despite an apparent uniformity in appearance, floristic groupings can be detected and four zones are provisionally outlined with a number of characteristic plants.2. Although currect…

Fire is a natural phenomenon in Madrean Province ecosystems. Suppression of natural fire has altered ecosystem processes, however. Recognition of these alterations has led to the adoption of let-burn policies by many management agencies, but a let-burn policy has become less…
