Strong streams

The following image is one I took earlier in the semester when I took a trip to Grandfather Mountain. Streams, not matter how big or small, play an important ecological role in their ecosystems. First off, they are a very important resource for non aquatic species as they serve as a source of drinking water. For aquatic species, they provide habitats and pathways to other rivers, streams, etc… They are also crucial in transporting nutrients and other goods throughout the area. If a tree falls, it can move materials/ debris downstream for species to make use of. For example, the beaver can use the branches to create dams. Which in turn are beneficial in preventing erosion and can provide valuable habitats for other species. Streams can also improve productivity throughout the environment. Streams with higher velocities can transport more sediments quicker providing and replenishing nutrients downstream. Another benefit of streams is pollution prevention. They are able to filter out less beneficial nutrients such as phosphorus and nitrogen leaving the water that flows into a larger body of water healthier.
