Background information and definitions
Topsoil can be a source of soil organic matter and help to improve water retention (Bruland & Richardson 2004). This might benefit wetland vegetation, particularly when creating new marshes. Topsoil may often be added to complement planting (current intervention) rather than without planting: upland soil will probably not contain seeds or fragments of marsh plants. Caution: Topsoil may contain seeds or fragments of undesirable vegetation.
Related actions: Add upland topsoil, other than to complement planting; Transplant wetland soil before/after planting.
