Why are forests considered biodiversity hotspots suggest four approaches?
A biodiversity hotspot is a region with large biological diversity. Forest serves as a reservior of biodiversity containing different species of plants, animals and many other micro-organims. Certain forest like the Amazon rain forest have diverse species and even the vulnerable and rare organisms.
Why are forests considered biodiversity hotspots?
Forests are considered “biodiversity hot spots” because they have very high level of species richness and a high degree of endemism. A person can effectively contribute towards the management of forests and wildlife by: … ii) Avoid discriminate cutting down of forest for the industrial purpose.
What are the 4 biodiversity hotspots in India?
Officially, four out of the 36 Biodiversity Hotspots in the world are present in India: the Himalayas, the Western Ghats, the Indo-Burma region and the Sundaland.
Why are forests considered biodiversity hot spots what would happen due to loss of biodiversity?
Forest is considered a biodiversity hotspot because different species of plants, animals and all other sorts of living organisms reside here. Loss of biodiversity leads to an immediate danger for food security for mankind.
Which is considered as biodiversity?
Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species, and of ecosystems.
What are considered as biodiversity hotspot?
To be classified as a biodiversity hotspot, a region must have lost at least 70 percent of its original natural vegetation, usually due to human activity. There are over 30 recognized biodiversity hotspots in the world.
Which is known as biodiversity hotspot?
A biodiversity hotspot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction. The term biodiversity hotspot specifically refers to 25 biologically rich areas around the world that have lost at least 70 percent of their original habitat.
What is biodiversity hotspot Why is India considered?
An area is known as a hotspot if it contains at least 0.5 per cent of endemic plant species. India is considered a mega-diversity hotspot due to the great diversity of organisms found here, ranging from eastern to western ghats to northern and southern India as well. Mainly Western ghats are now at high risk.
What are the criteria for defining a biodiversity hot spot which are the hotspots found in India discuss their salient features?
According to Conservation International, a region must fulfill the following two criteria to qualify as a hotspot:
- The region should have at least 1500 species of vascular plants i.e., it should have a high degree of endemism.
- It must contain 30% (or less) of its original habitat, i.e. it must be threatened.
In which forest the highest biodiversity is found?
Option A: The maximum biodiversity is found in tropical rain forests as they are less seasonal, they are neither too hot nor too cold and are more predictable. Therefore, this is the correct option. These kinds of environments help in promoting niche specialization and also leads to greater species diversity.
