Other biodiversity: Exclude grazers
A replicated, randomized, controlled before-and-after study in 2003–2005 in shrubland in northern Israel found that plant diversity decreased in previously grazed plots from which cattle were excluded, but only in moderately-grazed plots, and not in heavily-grazed plots. Plants: The number of plant species decreased in plots, after grazers were excluded, at one of two grazing intensities (data reported as effective number of species). Species diversity decreased in all plots, whether or not they had been previously grazed. Methods: Areas were ungrazed or grazed at moderate or heavy stocking densities (0.55 and 1.1 cows/ha/year, respectively) for 10 years before the start of this study. In 2003, two sites were established in each of these areas (0.4–2 ha for ungrazed plots, 20–30 ha for grazed plots). Fences were erected around five 10 x 10 m plots in the grazed sites, and vegetation was monitored in these plots and also in corresponding plots in the ungrazed area.
