Abstract

Abstract European wild rabbits (Oryctolagus cuniculus) are prolific herbivores, affecting natural and agricultural ecosystems. We installed 10 experimental units, each consisting of two fenced plots, one excluding all herbivores and one allowing rabbit access only, to estimate the impact of rabbit grazing in three vegetation types occurring in two dominant habitat types on Lemnos Island, Greece. Plant productivity was significantly higher in barley crops than on both fallow land and Mediterranean scrublands. Rabbit grazing caused significant reduction of productivity in barley crops and Mediterranean scrublands, but not on fallow land. Selective feeding and seasonal food availability may have shaped patterns of rabbit impact.
