They provide rich habitat for Many species of birds and an immense variety of mammals rely on wetlands for species of microbes, food, water, and shelter, especially plants, insects, during migration and amphibians, reptiles, breeding. birds, fish, and mammals. 5
    6. 6. Uses of wetlands water management Think of a wetland as a huge spongeWetlands store water when This helps in recharge andit is in excess and release discharge of groundwaterit to the ground during dryperiodsThey assist in flood controlThey reduce the momentum of water as it flows toa river or a stream, thereby reducing soil erosionThey are also important to thenutrient cycle. 6
    7. 7. Uses of wetlands environmentalWetlands plants Wetlands help Plants that grow in Many wetlandsand soil store retain sediments wetlands are very remove pollutantscarbon instead of and increase soil effective in filtering from surface runoffreleasing it to the fertility out water pollution and small streams.atmosphere ascarbon dioxide.Thus they helpmoderate global Mangroves can protect shorelines from strong winds and canclimate reduce the impact of hurricanes and tsunamis 7
    8. 8. Uses of wetlands – economicWetlands provide livelihoods by being a source of (Consumptive use )•Agricultural produce•Craft materials•timber production•Medicinal plants•Fishing•HuntingThey can also be recreation spaces (non-consumptive uses )Wetlands provide opportunities for humans to enjoy outdoor activities,such as canoeing, fishing, and bird watching. 8
    9. 9. How wetlands work Contaminants and sediments are filtered. Provides critical wildlife habitat Cleaner water outflow
    10. 10. Threats to wetlands Natural Natural disasters like hurricanes and floodsOver grazing by wildlife Drought
    11. 11. Threats to wetlands Anthropogenic1.Development Draining out wetlands for construction Damming them to form lakes or ponds Diverting water flow2.Pollution 3. Sand and gravel mining 4. Global warming 5. Acid rain
    12. 12. Ramsar conventionThe Convention on Wetlands -- called the "Ramsar Convention" – was signedin Ramsar, Iran, in 1971.An intergovernmental treaty - embodies the commitments of its membercountries to plan for the "wise use", or sustainable use, of all of the wetlandsin their territories. 12
    13. 13. What can we do? DO A PROJECT SHOW IT TO YOUR CLASS TALK TO THE OWNER OF A WETLAND Take an initiative, talk to the owners of a wetland on preserving them. ORGANIZE A FIELD TRIP Organize a class field trip to a wetland (preferably a destroyed one) and explain about the history of the wetland and why it was destroyed. MAKE SURE YOUR HOUSE ISN’T BUILT ON WETLAND
