Forest tree species showed authentic response to climate change. Trees in the Forest are macro organisms according to their size, thus affected more than other microorganisms. Forest trees response to climate change in their growth, survivability, spatial distribution, adaptation and mitigation of climate change. Forest growth, especially tree species growth is affected due to climate change induced phenomena like elevated temperature, salinity intrusion, changed precipitation and humidity etc. Tree species might be dislocated to other habitat area from their own. This spatial shift may be conducted in association with temporal passage of time. Forest tree species are also subversive to survivability. Tree species may experience adverse survival condition at both initial and mature stage. Morphological adaptation to changed climate can impose altered growth, changed phenology, fruiting pattern, elongation in seed dormancy etc. Future forest tree species in Bangladesh might experience all these misappropriation in near future. As natural resources do not tolerate any sharp change, an alteration in climatic condition of Bangladesh would thus be harmful to its growth and development.
