"If we continue at the current rate of deforestation and destruction of major ecosystems like rainforests and coral reefs, where most of the biodiversity is concentrated, we will surely lose more than half of all the species of plants and animals on Earth by the end of the 21st Century."

- E.O. Wilson, renowned biologist who popularised the term "biodiversity".

The state of forests: globally and locally

The Food and Agriculture Organisation of the United Nations estimates that natural tropical forests declined at a rate of 14.2 million hectares (approximately 0.7 percent per year), during 1990-2000 about the same rate of decline as during the previous decade (FAO, 2001).

Thailand has lost more than half of its natural forest cover since 1961, and is left with about 24% cover. Despite a ban on commercial logging since 1989, forest loss continues.

How FORRU began

In 1994, a few members of staff and students of the Biology Department, in Chiang Mai University's (CMU) Science Faculty, started to investigate the possibility of restoring forests on degraded sites in northern Thailand, by adapting the framework species method to local conditions. With a founding grant from Riche Monde (Bangkok) Ltd., and technical assistance from Bath University, U.K. (sponsored by the British Council), a research facility was established in collaboration with Doi Suthep-Pui National Park authority (under DNP) and named the Forest Restoration Research Unit (FORRU-CMU). It now consists of an office and research tree nursery at the park headquarters, a community nursery and field plots at the Hmong village of Ban Mae Sa Mai and an education unit, in the Herbarium Building of CMU's Biology Department.

What is the framework species method?

The framework species method relies on planting a minimum number of indigenous forest tree species for maximum ecological benefit. Framework species are selected for their potential to accelerate biodiversity recovery and enhance natural regeneration, creating a self-sustaining forest ecosystem from a single planting event. Originally conceived in northern Queensland to repair damaged tropical rain forest (Goosem and Tucker, 1995), the framework species method has been successfully modified to restore seasonally dry tropical forests to deforested sites in northern Thailand's conservation areas.

Essential ecological characteristics of framework tree species are therefore:

  • high survival when planted out in deforested sites;
  • rapid growth;
  • dense, spreading crowns that shade out herbaceous weeds and
  • flowering or fruiting, or provision of other resources, at a young age, to attract seed dispersing wildlife.
