What is Mangrove Forest?
A mangrove forest is a unique coastal ecosystem that grows in salty 🌊 or brackish water along coastlines, riverbanks, and estuaries 🏝️.
🌱 These forests are made up of special trees and shrubs called mangroves, which can survive in high salt levels 🧂 and low oxygen conditions.
🦀 Their tangled roots provide homes for many fish, crabs, and birds 🐠🐦.
🌀 Mangrove forests protect coastal areas from strong winds, waves, and erosion 🌊, making them crucial for both nature and people. 🌍💚

Mangrove Ecosystem in India
The mangrove ecosystem in India is home to a diverse range of plants 🌱 and animals 🦀, making it a vital part of biodiversity 🐦. India ranks as the third richest country in the world for mangrove diversity 🌍.
Mangrove Classification
According to the Champion & Seth (1968) Classification, mangroves fall under Type Group-4 (Littoral & Swamp Forests), which includes:
- 4A/L1 Littoral Forest 🌳
- 4B/TS1 Mangrove Scrub 🌿
- 4B/TS2 Mangrove Forest 🌱
- 4B/TS3 Saltwater Mixed Forest 🏝️
- 4B/TS4 Brackish Water Mixed Forest 🌊
These classifications highlight the ecological importance of mangroves in India’s diverse landscapes 🌍.
Mangrove Regions in India
India’s mangrove habitats are mainly divided into three regions:
- East Coast 🌅
- Home to 40 mangrove species from 14 families and 22 genera 🌱.
- West Coast 🌊
- Contains 27 mangrove species from 11 families and 16 genera 🌿.
- Islands (Andaman & Nicobar and Lakshadweep) 🏝️
- Andaman & Nicobar Islands have 38 species from 13 families and 19 genera 🦜.
- Lakshadweep has limited mangroves with only 3 species 🌳.
🔰 Indonesia holds the title for the largest mangrove cover globally 🌍, with an estimated 42,278 sq. km of mangrove forests.
Unique Mangrove Species 🐾
The Andaman & Nicobar Islands boast the highest mangrove diversity in India, featuring unique species like:
- Rhizophora lamarckii 🌱

Mangrove Cover Monitoring in India 🛰️
Since 1987, the Forest Survey of India (FSI) has been monitoring mangrove cover using remote sensing technology.
- The first assessment was on a 1:1 million scale 📏.
- From 1989 to 1999, assessments were conducted every two years at a 1:2,50,000 scale 📊.
- From 2001 onwards, assessments have been more detailed, using a 1:50,000 scale, allowing for better monitoring of mangrove ecosystems 🌿.
Conservation of Mangroves
Threats to Mangroves and Conservation Efforts in India
Mangroves are under significant threat due to:
- Rapid coastal development 🏗️
- Impacts of climate change, including rising sea levels 🌊 and frequent natural disasters 🌪️.
These factors contribute to the degradation of mangroves, making conservation and ecological restoration essential for long-term sustainability 🌍.
