Streambank Erosion Studies

Livestock grazing and access to water is a real problem for both the landowner and the ecosystem. There are a few ways for landowners to water livestock without allowing them access to streams, but often isn't considered because of the initial setup involved.

If livestock are allowed to always access the stream with no management, severe bank erosion and compaction can take place. This can lead to very sediment-laden waters and loss of soil as well as livestock fecal matter inputs.

Many of these streams and rivers go to recharge aquifers that we use for drinking water. The issue team is trying to quantify the impact livestock have on streambanks compared to streambanks with no livestock erosion. The Agroecology Issue Team is working hard on a resolution that is good for both farmer and ecosystem.

Right. Cows often take advantage of open streams and waterways, but can also severely erode streambanks.
