2004 Post Tsunami Resilience and Recolonization of Mangroves in South Andaman, India

摘要

Mangrove resilience and the scope for new venues of mangrove colonization in the Southern part of south Andaman were studied using satellite interpretation and ground truthing due to after the devastating 26th December 2004 tsunami. 1069.82 ha of Tsunami created wetlands were found in thirty five different villages.Fimbrisstylis littoralis, Acanthus ilicifolius, Acrostichum aureum,Rhizophoraspp. andAvicenniaspp. were observed in abundance in all the villages. However,Nypa fruticansandPandanus tectoriuswere found in four villages alone. Eight venues were found as newly colonized mangrove.Rhizophora mucronatawas existing in all the eight new venues whereasRhizophora apiculataandAvicenniaspp. was absent in 3 venues. The present study will act as reference point information for future investigation. The results of the present study provides a huge insight and hope in restorative models for degraded mangrove systems.
