The International Day for Biological Diversity is marked on May 22 to raise and create awareness about biodiversity issues. The theme of the day this year is – “We’re part of the solution #ForNature.”
The biodiversity of the Northeast is a genetic treasure of various forms of plants and animals. The region comes under the Indo-Burma biodiversity hotspot which ranks 6th among the 25 biodiversity hotspot of the world. Most of the North-Eastern states have more than 60% of their area under forest cover.
The following facts and figures from a research article, “Northeast India: A Unique Biodiversity Hotspot” by Jeev Prabha and Dr. Anju Jain (Daulat Ram College, DU) prove that the title of biodiversity hotspot given to North East India is quite appropriate:

Prevailing threats to biological diversity
Deforestation:
Cutting down trees is the primary issue faced by various wildlife resources. With deforestation, the forest cover is disappearing gradually.
Encroachment:
Encroachment of forestland is a serious threat to forests and their conservation. This is not only leading to the loss of the forest areas but our wildlife is also in danger.
Forest Fire:
Forest fires are now common, and having a terrible impact on the forest cover of the Northeast. Wildlife is also affected negatively by this issue.
