| Abstract: | Practically no information exists on the impact of human trampling on tropical rain forest vegetation. We studied three trails
with varying periods of use and recovery in a tropical rain forest in Costa Rica. Human impact on trailside plants was curvilinearly
related to use, as found by other workers in temperate zone vegetation. Recovery in a period of two years and eight months
had been rapid, and herbs and seedlings were more abundant along the recovering trail than in undisturbed forest. The results
imply that a shifting mosaic of trails, analogous to the mosaic created by light gaps, may be the best management technique
to minimize the impact of human visitors in tropical rain forests. |
