Figure 9.1. Map of the rainforests of southwestern South America. For comparison with the rainforests of northwestern North America the following climatically defined regions can be recognized: subpolar rainforests , 47°30' to 55°S;
perhumid rainforests, 40 to 47°30' S; and seasonal rainforests, 37°45' to 40°S. The
boundary between the two latter rainforest types varies by more than two degrees
of latitude according to position relative to orographic precipitation and rain
shadows.
