They concluded that there was a need to improve protected area planning as refuges for critical species, with SDMs proving to be a useful tool for providing projections that can then be incorporated into this planning process. Another paper by Shishir et al. also investigated the potential effects of climate change on a threatened Dipterocarp tree in Purbachal, Bangladesh. Using a model that incorporated nine different environmental variables such as climate, geography, and soil conditions, they looked at two climate scenarios. They found that precipitation and soil nitrogen were the largest determinants of distribution, and that suitable habitat for this species will decline by 21-28% relative to the present land area as a result of climate change.
