Abstract
The results indicate that the Prek Toal conservation program has been extremely effective. All species have recorded significant increases, with populations in some cases as much as 20 times greater than when the program was initiated. Some species, such as Oriental Darter and Painted Stork, are now colonising new nesting sites in Cambodia and Thailand. Similar range expansions might be expected for other species (e.g. Spot-billed Pelican) in future years. The colonies do not appear to be currently limited at Prek Toal, either for food or for nesting locations, although this may change as the populations continue to increase. The success of the Prek Toal program has contributed to recent proposals for revisions of species status, such as down-listing of Spot-billed Pelican based on the observed population recoveries.
