The eighth update of the Register of Italy’s Monumental Trees has been approved by Decree No. 237195, dated May 27, 2025, issued by the Director General for Mountain Economy and Forests. The updated list is available on the website of the Ministry of Agriculture, Food Sovereignty and Forests (www.masaf.gov.it), under the section “National Policies/Forests – Monumental Trees.” This update adds 95 new monumental trees and removes 3 specimens due to natural death, felling, or severe structural and physiological decline. As a result of this coordinated effort by the Directorate General of Forests, regional and autonomous provincial forestry services, and local municipalities (tasked by law with the census), the total number of officially recognized monumental trees or tree systems in Italy now reaches 4,749. These trees are notable for their biological and ecological value, age, size, shape, rarity of species, and their role as habitats for certain animals. Many are also important for their historical, cultural, or religious significance and contribute to shaping the landscape in both aesthetic and symbolic terms. They represent a cultural heritage of great public interest that deserves protection and appreciation. Some highlights among the new entries include: A double row of 163 black locust trees in Castelnuovo Don Bosco, nearly unique in Italy for its length (about 470 meters) and integrity, a magnificent Caucasian walnut tree in Campiglione Fenile (TO), with a trunk circumference of 195 cm and height of 26 meters, featuring a large branch reaching nearly to the ground, located in front of a historic villa, a white fir in Paularo (UD), with a circumference of 332 cm and height of over 53 meters, now the tallest native tree in Italy, a horse chestnut in Prepotto (UD), located at a Capuchin friary, approximately 150 years old with a circumference of 305 cm

The most common monumental tree species are the downy oak (616 specimens) and the European beech (251 specimens). The regions with the highest number of monumental trees are Friuli Venezia Giulia (543), Lombardy (431), and Sardinia (426). The Italian municipalities with the most registered monumental trees are Naples (53), Caserta (51), and both Trieste and Priverno (48 each).
