  1. Use ‘mosaic management’

    A replicated paired sites comparison in 2004-5 on six wet grassland sites in the Netherlands (Schekkerman et al. 2008) found that the reproductive productivity of black-tailed godwits Limosa limosa was significantly higher on sites managed under a ‘mosaic management’ agri-environment scheme, compared to on non-scheme sites (average of 0.28 chicks fledged/breeding pair for scheme sites vs. 0.16 chicks/pair on non-scheme sites). Differences were due to higher nest survival on mosaic management sites (50% vs. 33%), as there were no differences in the number of chicks hatching in successful nests (3.4 chicks/successful nest vs. 3.2 chicks/successful nest), or the fledging rate of chicks (11% fledging success on all sites). Nests were equally likely to be predated on scheme and non-scheme sites (32% predated vs. 37%), but were more likely to be trampled or destroyed by mowing on non-scheme sites (6% vs. 29%). Most fields in five scheme sites and about 50% in the sixth, had nests marked (to reduce losses due to farming activities); at non-scheme sites almost 100% of nest were marked in three, some in two, and none in one. The number of nests on different sites was not provided.
