Grazing effects on vegetation: Biodiversity, management, and restoration

Abstract In many regions, wild large herbivores have maintained open landscapes up to and including historic times, but, more recently, have been largely replaced by domestic livestock. By employing extensive and traditional grazing and browsing regimes, conservation actions support biodiversity and recovery in natural and degraded areas. However, grazing also plays other important ecological roles, for example, in the maintenance and/or recovery of important ecosystem services, such as biomass production and carbon sequestration. Understanding herbivore effects on plant composition and functional diversity, and ecosystem functioning and services, is essential for informing ecological theory and practice. The current Special Issue highlights that the effects of grazing on vegetation are strongly context‐dependent. The articles identify at least three major factors acting in concert, which are responsible for contrasting diversity and functional patterns of vegetation subjected to herbivores: (i) herbivore identity; (ii) grazing intensity; and (iii) vegetation type. Insights from this Special Issue imply that long‐term experiments across different habitat types and in underrepresented regions are needed to provide valuable information for grazing planning and management. They also demonstrate that integrating indigenous and traditional ecological knowledge, and considering socio‐economic contexts, can provide opportunities for improving sustainable grazing management.
