Community -based approaches to management of protected areas are increasingly being implemented in many areas. In a research study published in the journal Environmental Conservation (2005), the effectiveness of community- based approaches for conservation of biodiversity was examined in Annapurna Conservation Area (ACA) Nepal.

"A combination of ecological and social surveys were undertaken both within and outside ACA, enabling areas under community-based management to be compared with adjacent areas under traditional forms of land use.

Forest basal area and tree species diversity were found to be significantly higher inside ACA, associated with a decline in use of fuelwood as an energy source over the past decade. Social surveys also indicated that wild animal populations have increased inside ACA since the inception of community-based conservation. Observations of animal track counts, pellet counts and direct observations of selected species such as barking deer and Himalayan tahr indicated higher abundances within ACA."

It will be interesting to know the increase/decrease of wildlife population inside ACA before and after adoption of community based management.
