Riparian zone is a term that is often applied to vegetated or partially vegetated areas that are adjacent to rivers and streams. trailer In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone. If youve answered no to any of those questions, keep reading to learn more about riparian zones and how we can protect them! Here in the Pacific Northwest, scientists have named riparian zone degradation as one of the contributing factors to the decline in freshwater habitat for salmon, and current salmon recovery efforts involve riparian zone protections and management practices.1. startxref

This buffers the effect of peak runoff and keeps streams flowing longer. Particularly, the attenuation of nitrate or denitrification of the nitrates from fertilizer in this buffer zone is important. Worldwide riparian zones are among some of the most altered and degraded ecosystems.

These may spread along the watercourse and cause environmental degradation, but may stabilize the soil, place carbon into the ground, and protect the land from drying. They mark the transition area between aquatic (water) and terrestrial (land) systems. In New Mexico, floodplains, wetlands, and riparian areas provide important habitat for numerous species of birds, mammals, amphibians and reptiles.

[4] As such, a distinction can be made between parts of the riparian zone that connect large parts of the landscape to streams, and riparian areas with more local groundwater contributions.[5]. Of course, it is also very beneficial to be able to understand how our favourite natural environments function ecologically.

Activities associated with logging, such as sediment input, introduction or removal of species, and the input of polluted water all degrade riparian zones.[8]. [2] They supply shelter and food for many aquatic animals and shade that limits stream temperature change. If you are visiting a riparian area, there are some things you can do to minimize your impact as well. Perhaps youve walked along a riverside walking trail or simply admired their beauty from afar. Space is created for riparian sports such as fishing, swimming, and launching for vessels and paddle craft. H\0F~ 0000030223 00000 n These organic materials supply nutrients to the water streams and provide wildlife with food and habitat. Plant roots hold the sponge-like soils in place providing bank stability and preventing erosion, and those soils can soak up and store excess water to reduce flooding during high flows and then release it slowly during periods of low flow. Think twice before you decide to extend your lawn or build a dock! 0000003308 00000 n When riparian areas are intact and filled with trees, shrubs, grasses, and/or other vegetation, they act as buffers, protecting the river from the adverse effects of adjacent and nearby land use. 0000156914 00000 n

Unfortunately, the value of riparian zones is often overlooked. 0000019320 00000 n 0000027637 00000 n They provide native landscape irrigation by extending seasonal or perennial flows of water. The meandering curves of a river, combined with vegetation and root systems, slow the flow of water, which reduces soil erosion and flood damage. 0000001665 00000 n For one, it is essential to respect trail surroundings if you happen to be walking, hiking, or biking along a trail within a riparian zone. 0000010433 00000 n Live vegetation and the absorbent mat of accumulated plant litter and humus help to trap sediments before they reach the river.

In contrast, bare surfaces encourage runoff that carries unwanted substances which end up in the water bodies. 0000147278 00000 n Another technique is to quickly establish ecological succession by encouraging fast-growing plants such as "weeds" (pioneer species) to grow.

First of all, one of the most obvious benefits of riparian zones is the habitat they provide for wildlife. When riparian zones are damaged by construction, agriculture or silviculture, biological restoration can take place, usually by human intervention in erosion control and revegetation. 0000002373 00000 n Riparian zones dissipate stream energy.
