San Polo Montalcino - Sustainable Program 2022-2023

The analysis of the total samples collected highlighted a constant and abundant presence of all the main taxa considered in the IBS-bf index. In particular, the taxa with a frequency equal to or greater than 67% were (adult forms): Pulmonated Prosobranchs, Enchytraeids, Spiders, Opilionids, Mites, Isopods, Lithobiomorph Chilopods, Chilopods Geophilomorphs, Diplopods, Springtails, Thysanurans, Blattids, Embiopterans, Dermapterans, Coleoptera and Formicidae. The presence in 67% - 100% of examined samples of the main types of predator morphotypes (Lithobiomorph Chilopods, Geophilomorphic chilopods, spiders), detrivores (Pulmonated, Enchytraeid, Diplopods, Isopods) as well as Coleoptera, Embiopteran and Dermaptera, indicates an excellent propensity for the structuring of permanent trophic chains in the edaphic facies.
