Design an experiment that will determine what the ideal sheep grazing density is to maintain the heath land and stop scrub invasion.

EXPERIMENTAL DESIGN Conservation management of an upland heath nature reserve

Design an experiment that will determine what the ideal sheep grazing density is to maintain the heath land and stop scrub invasion. Write a short report explaining the key features of the experiment and how it will be undertaken. You can also use diagrams. Text within diagrams do not count towards the total, but text in diagram legends do count.
Because the report is short, you do not need to format it into sections.
