Wetland areas like swamps, marshes, etc., might suffer from a lower or a higher flow of water than normal due to the construction of dams. Threats Coastal Development. what techniques can be used to sample population abundance and distribution? Thus, dams have the power to permanently damage the wetland ecosystems. In many places across the world, the importance of wetland habitats have been recognized and such areas have been granted protection. Mangrove ecosystems are under threat from a changing set of pressures. Future threats to mangrove forests. Soil temperature is critical in the germination of seeds and the rate and duration of plant growth. While harvesting has taken place for centuries, in some parts of the world it is no longer sustainable, threatening the future of the forests. A huge variety of wildlife lives or breeds in the mangrove ecosystem, including numerous fish, crab and shrimp species, molluscs, and mammals like sea turtles. Conservation International is an active partner in the Global Mangrove Alliance, an organization of technical experts, policy makers and non-governmental organizations dedicated to promoting mangrove conservation and regrowth. Marshes, swamps, bogs, fens, deltas, mudflats, estuaries, etc., all qualify as wetlands. Threats for the future. Changes in sea level would alter flooding patterns and the structure and areal extent of mangroves. Insert the thermometer probe into the soil, Repeat the procedure three times and record the average, Scroll right until you find dEC (degrees celsius), Hold the Kestrel above your site, away from your body, When the reading stabilises (stops going up or down), record your measurement in degrees celsius, Carefully replace the case and return your equipment, Hold the sensor 1m above the ground over the quadrat, Scroll right until you find km/h AVG (Average Wind Speed), Hold the Kestrel for 1 minute at your site, away from your body, After 1 minute record your measurement in km/h. Water logged soils cause a slow rate of oxygen and nutrient replacement, as a result the soils surrounding mangroves are often low in oxygen and nutrients. Mangrove forests are incredibly important ecosystems. They have been mentioned below: Draining of wetlands to make space for agriculture or construction work is one of the biggest threats to such areas. Air temperature is a limiting factor upon plant and animal species. Th… In other places where higher temperatures are triggering droughts, the wetlands are also drying out. Threatened by climate change, pollution, overfishing, and human expansion, mangroves need our protection to survive. Thus, wetlands are getting lost both due to higher and lower water levels induced by the varying effects of climate change in different parts of the world. Oil spills may also cause large-scale damage to mangrove ecosystems (Duke et al, 1997). Like every ecosystem, the existence of species in wetlands also depends on a delicate balance of nature. However, equally important and at risk are seagrass ecosystems.
