There was little difference between grazed and ungrazed habitats in total breeding bird 

 density, but total bird biomass, bird species richness, and bird species diversity were 

 1.87, 1.75, and 1.62 times higher, respectively, in the grazed habitat. Small mammal 

 populations were almost a third higher on the grazed area than on the ungrazed area.
