Managing Large Herbivores in Protected Areas
Global Journal of Ecology
Review Article
By nature of their size, grouping behaviour, and central position within most trophic webs, large terrestrial herbivores -- namely ungulates and elephants -- tend to be both keystone and umbrella species. Their proportionately large impacts on ecosystems extend both top-down (i.e. regulation of vegetation), but also bottom up (regulated their predators). For these reasons, as well as their cultural and economic importance to humans around the world, large herbivores are among the most heavily managed species in any region. Large herbivores have historically been managed by the fact that hunting by humans – or an intentional or forced reduction in that hunting – effectively plays its own top-down role of regulating herbivores.
