Why do We Need Mangroves? 2 | Why Do We Need Mangroves? Mangroves protect human settlements from storm and typhoons. 2 | Why Do We Need Mangroves? Coastal communities need the mangroves for natural protection. 2 | Why Do We Need Mangroves? Shellfish gatherers at low tide. No mangroves – less shellfish. 2 | Why Do We Need Mangroves? Mangrove roots hold sediments back and prevent erosion. 2 | Why Do We Need Mangroves? Fish, shellfish, crabs and other species need mangroves to survive. 2 | Why Do We Need Mangroves?

Plastic bags and other waste is a major threat for mangroves. 3 | What is Dangerous For Mangroves? Goats can destroy mangrove seedlings and damage mature trees. How Can We All Protect the Mangroves? 4 | How Can We All Protect the Mangroves? Rhizophora propagules grow up in a mangrove nursery. 4 | How Can We All Protect the Mangroves? These seedlings struggle to survive in a badly choosen planting site. 4 | How Can We All Protect the Mangroves? Mangrove seedlings can be easily damaged or even destroyed. 4 | How Can We All Protect the Mangroves? Mangroves usually produce enough seeds for natural rehabilitation. 4 | How Can We All Protect the Mangroves?

A general clean-up with students at a marine sanctuary. 4 | How Can We All Protect the Mangroves? Raising awareness! – Talking about the need for mangroves. 4 | How Can We All Protect the Mangroves? Former mud flats in Kalibo turned into a mangrove forest again. Teaching About Mangroves! 5 | Teaching About Mangroves!
