Background information and definitions
This action involves excluding livestock – with physical barriers such as fences or hedgerows, or virtual barriers involving GPS trackers and negative sounds or electric shocks (SRUC 2015) – from an area of natural, ungrazed marsh or swamp. Here, “ungrazed” refers to the recent history of a site, so studies of sites that have not been recently grazed and so have regained their natural ecological character would also be included here.
Domestic livestock can directly consume vegetation, destroy vegetation by trampling, create bare patches of ground (e.g. repeatedly used tracks), affect water infiltration and flows by compacting soils, affect nutrient balance through excretion of waste products, and import seeds of undesirable plants (Morris & Reich 2013).
