A biodiversity hotspot is a region of the Earth that is extremely biologically diverse and also under severe threat due to habitat loss, climate change, or extensive species loss. Guarding these regions from further damage is considered environmentally and culturally important, as they host organisms that are not found anywhere else on Earth.
Forest serves as the reservoir of biodiversity containing different species of plants, animals and all other sorts of living organisms. Many forests include a very rich diversity of species including most rare and prior to extinct species.
