Type of protected area - Where it is located
Typology: State Natural Reserve; established with D.M.A.F. December 11, 1973, included in the Regional Natural Park of the Ticino Valley.
The Bosco Siro Negri integral nature reserve is a small strip of the Po Valley that was donated to the University of Pavia in 1967 by Giuseppe Negri, a citizen of Pavia and a great lover of nature. In 1970, on the occasion of the European Year for the Conservation of Nature, organized by the Council of Europe, the University decided to bind the forest as an integral nature reserve which, due to the donor's wish, was given the name of his brother Siro.
The Siro Negri forest was established as a natural reserve by the Italian State with the Ministerial Decree of 11 December 1973 of the Ministry of Agriculture and Forests.
In homage to the donor's intentions, the University undertakes to preserve the forest intact, thus not implementing any management intervention and allowing access only for scientific, educational and surveillance research purposes. Thanks to these restrictions, the Bosco Siro Negri can be defined as an integral reserve, and has taken on a significant naturalistic and scientific value.
The area is located on the right bank along the course of the Ticino river, about fifteen kilometers from the city of Pavia, in the municipalities of Zerbolò and Torre d'isola and belongs to the wider Site of Community Importance IT 2080014 Bosco Siro Negri and Moriano , which covers an area of 1,352 hectares.
A small territorial expansion of the Reserve is expected in the near future which currently occupies an area of about 9 hectares.
The managing lens of the reserve, the Department of Earth and Environmental Sciences of the University of Pavia, organizes scientific research, educational and dissemination and communication activities.

The vegetation of the Reserve is forestry. The most common trees are the English oak (Quercus robur), different species of poplars (Populus alba, P. nigra, P. canescens) and locust (Robinia pseudoacacia) while the most frequent high shrubs are the hazel (Corylus avellana), the hawthorn (Crataegus monogyna) and the pado (Prunus padus).
Low shrubs are generally sporadic, cover no more than 15% and rarely have a height greater than one meter; among the most recurrent species: privet (Ligustrum vulgare) and priest's cap (Euonymus europaeus). The undergrowth herb carpet has a variable appearance with the seasons.
The forest vegetation refers to the types of alluvial oak-ulmets, which can be classified in the phytosociological association Polygonato multiflori-quercetum robori.
Information for the visit
At the Reserve Education Center, many educational and popular activities are promoted for children and adults, families and school groups who want to discover more closely the natural riches of the woods that characterize the Po Valley.
Numerous scientific research activities are carried out each year in the Reserve, aimed at the preparation of Degree Theses or the publication of scientific articles of international importance.
Bosco Siro Negri is located in the Municipality of Zerbolò and being an integral natural reserve it is not intended for the visit by the public, but to the conservation of the spontaneous forest vegetation of the plains and related species in-situ, that is, where they naturally exist.
