An area is known as a hotspot if it contains at least 0.5 per cent of endemic plant species.

What is a hotspot and how is it formed?
A hot spot is a region deep within the Earth’s mantle from which heat rises through the process of convection. This heat facilitates the melting of rock. The melted rock, known as magma, often pushes through cracks in the crust to form volcanoes. … Instead it occurs at abnormally hot centers known as mantle plumes.
