Taking Back the Land: Factors Aiding or Constraining Regeneration of Damaged Mangrove Forests in South Andaman Island

Background

The mangrove forests in the Andaman Islands of India have suffered severe decline, which has only been enhanced by the 2004 tsunami season. While there has been numerous resources and efforts put into restoring and reforesting these mangroves, much of them have been futile. This study seeks to understand why.

Goals & Approach

The study aims to identify key factors that prevent the natural regeneration of different species of mangrove trees and to determine where regions can allow for natural regeneration and those that require human restoration interventions. Both monitoring of propagules germination and nursery experiements were conducted. 

Reported Takeaways

By 2014, the project had mapped the changes caused by the 2004 earthquake and tsunami, accessed regeneration patterns in two districts (Lohabarak in South Andamans and Mayabunder in Middle/North Andamans), and set up a long-term mangrove monitoring program. Looking ahead, the project hopes to continue testing best restoration practices and extend the focus of study to North Andaman.
