The paper presents results of the first survey of nature monuments conducted after WWII in seven communes of the Szamotuły county: Duszniki, Kaźmierz, Obrzycko, Ostroróg, Pniewy, Szamotuły and Wronki. A total of 114 nature monuments were inventoried – single trees account for 76.3% of all monuments, while clusters of trees – 20.2%, respectively. A locality of Osmunda regalis, a cluster of Pinus mugo as well as two erratics are also monuments. A total of 384 trees of 25 species were inventoried. In case of single trees considered nature monuments the most numerous group is composed of English oaks (44 trees – 50.6%), while among tree clusters Scots pines predominate (201 trees – 67.7 %). The biggest number of monuments is found in state forests (57.9%) and former manor parks (21.9%). Plaques of NATURE MONUMENT are placed on 54% trees ranked as monuments and 60.9% tree clusters, while only every eighth monument tree cluster bears the appropriate information plaque. Such a plaque was also placed on one erratic. The most impressive tree in the analysed county is a London plane from Pożarów, with a circumference of 7.15 m.
