One of the most interesting natural reserve features of the Oak Wood or Bosco delle Querce is its biodiversity, a term coined by the UN conference on the environment and development in 1992 held in Rio de Janeiro that defined it as “the variability of the living organisms, terrestrial and aquatic ecosystems, and the ecological complex they constitute.” If in fact, we were to carefully observe the park of Seveso we would note how this green area, created due to the dramatic events of 1976, is today an important natural heritage in Lombardy, capable of hosting a great variety of animals and plant essences.

In view of its historical founding, the park, already in 1998 could count 12,000 trees and almost 24,000 shrubs, a plant heritage four times that of its condition when created. The Wood’s management policy, that changed from a formal and unnatural approach to a more spontaneous one, slowly brought about the creation of re-naturalised areas named “dirty areas,” on which no pruning, cutting or similar anthropic interventions were effected. From 1989, for example, the green areas subjected to cuttings were gradually reduced, and passed from 28 hectares in 1989 to16 hectares in 1991.
Inhabited by a multitude of animals, the Oak Wood presents some specific areas, among which, broadleaf woods generally consisting of typical plants of temperate climates with little need of water; shrubs that developed due to the regional plants of the 1980s; the grassy areas, only partly subjected to periodic cutting, the humid zones, that despite their small dimensions and their purely artificial nature possessed an unusual biological wealth.
