Manage wetlands or ponds by grazing or cutting to prevent succession
A replicated, site comparison study in 1996 in 24 montane fens in Switzerland (Wettstein & Schmid 1999) found that fens managed by mowing had more species of butterfly than fens managed by cattle grazing. The species density of butterflies was higher on mown fens (8.9 species/transect) than on grazed fens (7.7 species/transect). Twelve of 23 fens (0.8–15.4 ha) were managed by mowing, and 11 by cattle grazing. From July–August 1996, butterflies were surveyed once on a 10-minute walk along each of three 540-m transects/fen.
