As such, understanding how grazing impacts different aspects of the ecosystem is of especially great importance. This study uses a range of approaches to explore the potentially contrasting effects of grazing across human-managed, livestock-grazed systems and natural, wildlife-grazed systems. The first chapter uses a short-term, small-scale approach in assessing differences across management type in plant community composition following a relaxation of grazing.
