Background information and definitions
This section considers using grazing vertebrates (e.g. sheep or cows) to control problematic plants. Grazers remove shoots or flowers, limiting plant growth and/or reproduction. They might selectively graze certain plant groups or species (Grant et al. 1987), creating space for other species to grow. Caution: Trampling, erosion and nutrient enrichment from grazers can have negative impacts on peatlands, especially if the density of grazers is high.
Key peatland types where this action may be appropriate: bogs, fens/fen meadows, tropical peat swamps.
Related actions: interventions to address domestic livestock as a threat, such as exclusion; grazing to manage plants as part of a traditional disturbance regime.
