Why rainforest does not regenerate after total clearing

When large areas of rainforest are cleared without leaving surrounding forest the area is unlikely to recover. After clearing, tropical soils rapidly become inhospitable to growth due to the loss of symbiotic soil organisms, swift leaching of nutrients caused by heavy rains and intense sunlight, and the disappearance of animal species important for pollination, seed dispersal, and seed processing. Forest regeneration is further stunted by the rapid encroachment of tough grasses and shrubs after slash-and-burn agriculture.
