In one study done in 1995, spring use of Ivermectin was found to have detrimental effects on fly populations. While the use of Ivermectin may be beneficial for livestock, it means that there were fewer flies to break down dung patches. At moderate levels, trampling creates small basins for water and grass seedlings to catch, but when too excessive, trampling compacts soils and may contribute to wind and water erosion. Trampling and exposing the streambank of moist riparian areas can become a problem. Grazing systems for riparian areas are becoming a new focus of range management.
Riparian areas tend to have greater potential for higher numbers of native plants and animals.
Good management of riparian areas may also mean increased forage productivity and mire stabilized incomes for livestock producers. In summary, applying good range management practices on PFRA pastures must translate into a healthy level of biodiversity. This means moderate levels of grazing and use of rotational grazing systems. Use of grazing systems that allow adequate rest on riparian vegetation sites is an important step in conserving biodiversity.
