Methods

Vegetation cover was sampled by pointing with 70cm x 70cm quadrats, 3.Plot size: (m2)70cm x 70cm1. Pointing 2.The Abundance units: 100 hits/plot in 2001-2002 and 81 hits/plot in20083.Plot size: (m2) 2 adjacent 70cm x 70cm plots so T1 + T2 = 0,98m2, T1 alone = 0,49m24.Approx subsite area (m2) : 2 habitats (Mesic polygon +Mesic prairie)approx 1km x 1km with 4 blocks each with 3 replicat T1+T2/block.5.List missing taxa and year missing (e.g. no cryptogams sampled in 2004; no litter sampling in 2008): following groups appear to have been completely omitted in 2008
