  1. Use wire fencing to exclude large native herbivores

    A replicated, paired-sites study in 1979-1990 in Mediterranean oak woodland in south-east Portugal (Bugalho et al. 2011) found that excluding red deer Cervus elaphus and fallow deer Dama dama increased the biomass of herbaceous species and the relative cover of legumes Fabaceae, but did not affect the number of plant species. The biomass of herbaceous species was 177 g/m2 in ungrazed and 100 g/m2 in grazed plots. Relative cover of legumes was 10% in ungrazed and 5% in grazed plots. The total number of plant species was similar in grazed (44) and ungrazed (42) plots. Five blocks of paired ungrazed (fenced) and grazed (unfenced, grazed mainly by red deer and fallow deer) plots (25×25 m) were established in the study area in 2001. In 2003, plant biomass and the relative cover of plants were measured in four subplots (2×4 m) within each plot.
