Abstract
Calcareous grasslands are among the most speciesrich ecosystems in temperate countries However these ecosystems have suffered from fragmentation and destruction during the last century We studied the response of calcareous grassland plant diversity to landscape changes in Belgium Results indicated that high area loss since 1965 old habitat patches exhibited an extinction debt inverse to low area loss old habitat patches little depending on the area loss threshold 60 70 80 or 90 considered for the distinction between the high and low area loss patches However human activities also created new habitat patches in the landscape and therefore provided opportunities for calcareous grassland plant species to colonize new habitats This also provided opportunities to study species colonization abilities in the context of habitat restoration We analyzed species richness in new patches compared to old patches in order to detect colonization credit We detected the presence of a colonization credit in new patches when using high loss old patches area loss 80 exhibiting an extinction debt or all old patches as a reference However when the reference was low loss old patches alone area loss 80 less likely to exhibit an extinction debt no colonization credit was detected In addition species composition was similar between new patches and old patches These results are encouraging for restoration programs However the results indicated that the presence of an extinction debt in reference habitats could lead to inaccurate conclusions in restoration monitoring Therefore extinction debt should be considered when choosing reference habitats to evaluate restoration successThis work was undertaken as part of the project “Development and test of a methodology for the elaboration of Natura 2000 sites designation acts” funded by the Walloon Public Service DGARNEDNF This study was supported by the FRSFNRS contract FRFC 2455605
