Why have mangrove forests in particular been selected for conservation programs in Sri Lanka and elsewhere in the region? How do they differ from other forests in terms of their own vulnerability and their benefits to local communities?

Mangroves are a vital component for natural fisheries in those settings, such as shallow tropical coastlines, so protecting them serves a longer sustainable purpose for fishing communities. The big difference is that the trees themselves are not necessarily the most valuable aspect, wildlife and coastal flood protection is just as important.
