Hot spots of biodiversity

There is a in situ conservation. the hot spots are the richest and the most threatened reservoirs of biodiversity on the earth.

To qualify as a biodiversity hotspot, a region must meet two strict criteria:

A) It must have at least 1,500 vascular plants as endemics - which is to say, it must have a high percentage of plant life found nowhere else on the planet

B) It must have 30% or less of its original natural vegetation. In other words, it must be threatened.

6 large mammal species have been discovered in this region: the Large-antlered Munt jac, the Annamite Munt jac, the Grey-shanked Douc, the Annamite Striped Rabbit, the Leaf Deer, and the Saola.

Endemic freshwater turtle species, most of which are threatened with extinction, due to over-harvesting and extensive habitat loss. 

There are also 1,300 different bird species, including the threatened White-eared Night-heron, the Grey-crowned Crocias, and the Orange-necked Partridge.
