UNDERSTANDING FOREST REGENERATION – LEARNING FROM NATURE
Some people take the view that deforested areas should be left to recover naturally and that forest restoration is unnecessary interference with nature. This view fails to recognize that the situation in most large deforested areas is far from “natural”.

Humans have not merely destroyed forest; we have also destroyed the natural mechanisms of forest regeneration.

The elimination of most large seed-dispersing animals by hunting now makes it almost impossible for climax forest to re-establish itself by natural means. Nearly all wildfires, which burn any tree seedlings that may become established, are also started by humans. Unless a concerted effort is made to restore the former mechanisms of forest regeneration, most deforested areas in the tropics will remain dominated by herbaceous weeds and maintained by frequent fires. Forest restoration is merely an attempt to correct the “unnatural” creation of so many large deforested areas by Humankind. Its success depends on a thorough understanding of the natural mechanisms of forest regeneration and consequently, development of methods to re-instate them (see Parts 4 & 5). Therefore, in this part, we present an overview of natural regeneration of seasonally dry tropical forest ecosystems, based mostly on FORRU’s research on the forests of Doi Suthep-Pui National Park in northern Thailand.
