Use covers/barriers to control problematic plants

Background information and definitions
Covers such as plastic sheeting or straw mulch could be used to control problematic plants. These may act as direct physical barriers (e.g. temporarily covering the peatland surface, to prevent seeds from establishing whilst they are viable) and/or indirect barriers that modify environmental conditions (e.g. opaque covers that block light, prevent photosynthesis and kill problematic plants). Caution: Covers may also kill desirable species. Temporary application, when the peatland is most vulnerable to invasion by problematic plants, could solve this problem.
Key peatland types where this action may be appropriate: bogs, fens/fen meadows, tropical peat swamps.
