effects of grazing
In this video, I demonstrate the effect of exclosures, which exclude the herbivores from a small vegetataion plot.
By comparing paired plots, one exclosed, one grazed, I can study the effect of the herbivores on the vegetation.
These exclosures are 10 years old. Inside a big variety of species with flowering grasses, Cardamine and Equisetum. On teh grazed plot, only mass can be found.
Within the grazed plots of 2 x 2 m2 I have made new exclosures of 1 x 1 m2, to continue this study in 2013.
