To Tony Turrini, a National Wildlife Federation attorney specializing in wetland regulations, the small, seemingly harmless fills allowed by the Corps' nationwide permit program represent a critical problem. She grew up in a log house in the hills of a small town in Upstate New York. Frogs, turtles, salamanders, minnows, and crayfish are among the species that live in or near the pond, while others feed on insects found along its banks. Therefore, it is important to take precautions when building a retention pond in an area where there are likely to be children or animals. This can be done by regularly removing any excess plant growth, adding additional aeration devices to improve circulation and oxygen levels, and removing any dead animals that may have accumulated around the pond. In 2012, hundreds of animals, including many vulnerable one-horned rhinos (Rhinoceros unicornis), were killed in floods that swamped Kaziranga National Park in the Indian state of Assam. WebThe disadvantages of wetland restoration are minimal. 0000023436 00000 n A larger pond will have a higher water quality because changes in water chemistry will be slower.

Filling one small parcel of wetland may seem harmless, but the damage adds up when several property owners in a watershed also begin draining and building. In particular, coastal wetlands that serve as natural buffers against flooding and storm surges could be lost due to rising sea levels or increased surface runoff in wetland areas leading to saltwater intrusion into freshwater systems. In fact, according to this article by the US Environmental Protection Agency, "Wetlands are among the most productive ecosystems in the world, comparable to rain forests and coral reefs.". WebRetention ponds work to control stormwater by retaining and treating contaminated stormwater runoff. The ecosystem wetlands provide for plants and animals is just the beginning of the reasons wetlands are protected by law. Research the flood risk for the area in which you plan to build. The restoration of natural ecosystem services, including flood and erosion protection benefits, largely outweighs any disadvantages. 14 0 obj

There also may be seasonal flooding due to winter thaw and spring rains. The aftermath was devastating; deadly waterborne diseases like dysentery and cholera spread quickly, and those who survived faced the threat of starvation.The human cost of flooding can be large, but events like this have a big impact on the natural world too, and the effects are not always negative. 0000016440 00000 n %PDF-1.6 % Because a pond is a living environment, it will eventually become more effective as plants and animals grow. Retention ponds also help gradually recharge groundwater levels by recharging the groundwater aquifer with rainwater. ef7h9uMh~T-M>}HPKyA-OxHm^CC^@@qSZW)KQN ,n3ms`v2[r &v 4'Szt32hK_!on I&!~:Y+{nkUFqnrdFtyF If contaminated floodwater enters the ocean it can affect water qualityand disrupt delicate ecosystems, such as coral reefs. Floods can be destructive to humans and the natural environment, but they also help to drive biodiversity and are essential to the functioning of many ecosystems.

Floodwater gets absorbed into the ground then percolates through layers of soil and rock, eventually reaching underground aquifers. Now another permitNationwide Permit 29has come under fire from conservationists. When rainfall occurs rapidly, water can flow downhill to a nearby body of water which causes erosion. The retention ponds depth affects how much water it can hold before overflowing. Instead, much of that water poured over levees and into people's homes. The river captures rainfall from far to the north in the highlands of Angola. Storm water sluicing through the drained wetland "ended up creating the largest eroded gulley in our county," he says. Adapted from Brown and Schueler (1997b) Constructed Wetland 0.60-1.25 Although little data are available to assess the cost of Produced biomass can attract wildlife and help with small-scale bioenergy production.
