Control of Molinia in heather moorland after reduction in sheep grazing - OC9418

This study will aim to evaluate the effects of burning, grazing and herbicide application treatments on the control of Molinia in heather moorland. Six study sites will be established in 3 ESAs in England. Within each site, one ‘white’ moorland (dominant Molinia) and one ‘grey’ moorland (Molinia and Calluna) will be located. Each site will comprise 2 blocks, each containing eighteen 10 m2 plots. Three grazing treatments will be applied to each block as follows: no grazing; existing grazing pressure; and summer grazing (April to October). Each grazing treatment will be split into two 10 x 30 m areas and subjected to either burning or no burning treatments. Each grazing/burning treatment will be further subdivided and subjected to low or high dose herbicide or no herbicide treatments. Within each of the 36 plots at each site, four 1m2 quadrats will be surveyed annually and all major plant species identified. Grazing will be evaluated using dung plots. Percentage offtake of vegetation by grazing will be measured each year. The study will also investigate the effects of selective herbicides, cutting and the use of a weed-wiper on controlling Molinia on heather moors and evaluate the effectiveness of novel heather seeding techniques.
