Download Evaluation of CSA grazing management and wetlands in hill country

This study used a paired catchment experimental design to test the effectiveness of three mitigation strategies targeting the critical source areas (CSAs) that were ephemeral streams in deer grazed pastures. Four small catchments on the same hill slope (2.2 to 3.6 hectares) were monitored for two years. In third year, a grazing mitigation option was applied in three catchments, with the fourth catchment left unchanged as a control. Post-treatment monitoring was conducted for a further two years.
