What is a Riparian Zone?
It may sound like something out of science fiction, but, chances are, you see Riparian Zones nearly every day!
Riparian Zones are unique areas along the edges of streams, lakes, or other bodies of water that are shaped by the ebb and flow of water.
What makes them so special?
Despite making up less than 2% of land area in the Southwest United States, Riparian Zones are integral to keeping our waterways safe and healthy. Riparian Zones are powerhouses of biological diversity, that provide habitat for many different species of plant, animal, and bacteria. The plants that live in the Riparian Zone combat soil erosion and help maintain water quality by removing excess sediment or nutrients, helping keep our water safe and clean.
In addition, all sorts of animal interact with Riparian Zones every day:
- Birds nest in the overhead trees
- Deer, skunk, and raccoons forage for food on the ground
- Fish relax in under the plant’s shade
- Even humans fish and picnic by the Zone’s beautiful scenery
Threats to the Riparian Zone
Urban Sprawl – The development and expansion of urban zones often leads to removal of the Zone’s vital vegetation and can change the structure of the water bank. Without the proper vegetation, flooding can occur more easily, and harmful sediments can spread throughout the area.
Invasive Plants – The presence of invasive plants puts harmful stress on Riparian Zones as native plants need to compete for necessary resources and space.
