Main Body

Geographical factors responsible for growth of mangrove:

1Tropical and sub tropical climates: providing temperature suitability for mangroves.
2Nutrient carrying eastern flowing rivers leading to productivity in the delta region: suitable for growth of mangroves.
3Bay of Bengal Branch: providing ample precipitation for growth.
4Suitable salinity: leading to growth of Mangroves in India.

Role of mangrove in coastal ecology:

1Protect as border guarding force: from high tide and wave impact leading to lower impact and disaster.
2Ecosystem services: Productivity leading to forest and aquaculture opportunities.
3Preservation of biodiversity (eg) Habitat of Royal Bengal Tiger in Sundarban and general.
4salt Tolerance nature leading to sustainability of salt erosion and salinization.

4Suitable salinity: leading to growth of Mangroves in India.

(i) Climate and sea surface drift leading to thrust to mangrove (more than 70% under threat).

Challenges to mangroves:

(i) Developmental activities leading to deforestation and exploitation

(ii) River pollution hampering in Gharials (baseline shown in IFR-2023)
