Coridorul Jiului is a Natura 2000 area located in the south-western part of Romania, benefiting from a climate with sub-Mediterranean influences that favours the presence of thermophilous species of the genus Cerambyx. Observations carried out in May-September 2022-2023 led to the identification of four species of Cerambyx, out of the five species present in the Romanian fauna: C. cerdo, C. miles, C. welensii, and C. scopolii. Although the suitable habitat is represented by forests with secular trees, the species have also been recorded in younger oak habitats, 50, 60 and 70 years old, with prematurely aged trees, due to the present in the area of forests planted on sandy soil that provides a poor nutrient environment for the trees. The species C. cerdo recorded the highest numerical abundance values, 154 individuals, compared to 4 and 7 individuals, respectively, for the other three species. The species populations are particularly notable in habitat 91M0 in Dealul Branului-Bâlteni (north of the area) and Dâlga (south of the area). Our observations reveal that the oak forests in southwestern Romania are an important reservoir for populations of Cerambyx species, contributing to the conservation of longicorns biodiversity under the implementation of appropriate forest management strategies.
