Abstract
Urban parks can harbour small populations of saproxylic insects of high conservation concern, such as Osmoderma eremita and other rare beetles. These areas often host old trees which have become very uncommon in rural areas where they are threatened by commercial forestry management procedures based on frequent tree cutting. Nevertheless, old trees of urban parks may represent a hazard for public safety and are sometimes cut by management authorities. The aim of this work was to assess the loss of reproductive sites for saproxylic beetles of the Scarabaeidae, Lucanidae and Cerambycidae, when felling plans are adopted according to a Visual Tree Assessment Procedure (VTA), in a Mediterranean urban park. On July–August 2004, 1,247 holm oaks were surveyed within the border of an urban park of Rome (Villa Borghese). The occurrence of saproxylic beetles (i.e. the presence of frass, living insects or their remains) was verified in 66 old holm oaks, 41% of which were doomed to cutting by VTA. Eleven of these trees (41% of the trees doomed to be cut) held fragments of adults and sometimes living larvae of Osmoderma eremita, and four of them (36%) were included in the felling plan. The presence of Osmoderma eremita in tree holes was more frequent in deep cavities. The presence of frass in the cavities was positively associated with tree height and a high degree of damage at the root collar and negatively with the presence of hole-nesting birds.
