Riparian Zones

What is a riparian zone?

The word riparian is defined as "Of, on, or relating to the banks of a natural course of water."

The word "riparian" is derived from the Latin word ripa, meaning river bank.

A riparian zone is the shoreline or banks of a river between land and the body of water. Plant communities along these riparian zones are called riparian vegetation, characterized mostly by hydrophilic plants.

Riparian zones are very important in studying ecology, environmental management, and civil engineering because of their biodiversity and the effects they have on aquatic ecosystems. A riparian zone may be found in many forms including woodlands, wetlands, grasslands, and there are even riparian zones without vegetation.

A riparian zone can be naturally formed or man-made for soil stabilization or restoration. These riparian zones are important because they act as natural biofilters, protecting the aquatic environments from too much sedimentation, pollution and erosion. The riparian zones may provide shelter and food for a wide array of aquatic wildlife and also provide shade that is an essential part of stream temperature regulation. If a riparian zone becomes damaged, biological restoration can take place by human intervention to control erosion and replace vegetation.
