Environmental improvement and conservation of useful pastures for wild herbivores in a Regional Park on the Apennines mountains

Abstract

In order to investigate some effects of the environmental management with faunistic purpose on pastures located on the Apennines mountains, in open areas subjected to bracken fern (Pteridium aqulinum) infestation, samples of vegetation were taken for three years on an open area in the Regional Park of “Laghi di Suviana e Brasimone” (BO). Experimental samples, taken before and after the agronomical works, showed the effects of the pasture improvement on botanical composition, richness and biodiversity. The agronomical pasture management produced a considerable decrease in bracken density and an increase on biodiversity, and the final average value of the Pastoral Value index was quadruplicate. These results confirmed the effectiveness of the actions carried out and the importance of maintaining a continuous programme of pasture management through annual clearing of vegetation.
