  1. Other biodiversity: Use grazers to manage vegetation

    A replicated site comparison in 2007 in montane forested pastures in northwest Spain found more ground beetles, and a higher diversity of ground beetles, in goat-grazed or sheep-grazed pastures, compared to ungrazed pastures. Invertebrates: Beetle diversity was higher in grazed pastures, compared to ungrazed pastures, in one of two groups (ground beetles, but not rove beetles: data reported as effective number of species). More ground beetles were found in grazed pastures, compared to ungrazed pastures (19–510 vs 9–220 individuals), but similar numbers of rove beetles were found (56–240). Similar communities of ground beetles, but different communities of rove beetles, were found in grazed and ungrazed sites (data reported as statistical results). Methods: In 2007, three grazed sites and three abandoned sites were selected (abandoned at least 20 years previously). Invertebrates were collected in June–October (10 pitfall traps/site).
