On top of the Guardia Sanframoni territory, the wildlife oasis of Monte Clesco extends for over 30 hectares. The area is managed by Legamabiente.
Pines, chestnut and maples of Hungary mix together with local shrubbery like brooms and rosehip. The wildlife is varied, with pheasants, quails, does, wild horses and deers. These latters are a local attraction as schoolchildren come here to participate to hikes and educational workshops.
