  1. Mow or cut reedbeds

    A controlled study in 1993-1995 in an area of peat marsh in Overijssel, the Netherlands (Graveland 1999), found that reed warblers Acrocephalus scirpaceus and sedge warblers A. schoenobaenus nested at significantly lower densities in areas of recently cut reedbed, compared to uncut areas (reed warblers: 0.8 nests/100 m of shore for cut areas vs. 2.0 nests/100 m for uncut; sedge warblers: 0.03 nests/100 m vs. 0.7 nests/100 m). There were no significant difference in the fledging success of unpredated nests in cut and uncut reed, but nest predation of reed warblers was higher in cut reed (33% predated in cut areas vs. 17% in uncut areas). There was no difference for sedge warblers (73% vs. 43%).
