Grazing Management - Techniques for Reducing Intensity of Use by Influencing Distribution

 

 

Stable Access Points

Providing stable access points to water can significantly reduce streambank trampling. There is evidence livestock prefer stable footing and clean water and will travel a considerable distance to reach them. For example, the large-gravel approachways in Figure 3-11 resulted in a marked improvement in stability of a sedge-dominated meadow streambank which previously had suffered considerable bank deterioration.

Figure 3-11
Livestock will walk up to a quarter-mile to gain better footing for stream access.

 


Proven designs are now available which reduce the impact of concentrating livestock at a few locations. These include "side bars" of logs or rock (as illustrated in Figure 3-12) and web matting, as well as the gravel itself. One ranch has even built a simple bridge to provide livestock access on both sides of a stream in Silver Bow County. The result has been much better livestock distribution and use of very productive riparian vegetation. At the same time, degraded streambanks are revegetating and healing.

This stream crossing was installed at an existing access location.

Streambanks with a large percentage of rock greater than gravel-size have an inherent stability which makes such devices less necessary.
