Abstract. In 2014, an inventory of protected Natura 2000 saproxylic beetles from the Prigoria-Bengeşti protected area in Gorj County (Romania) was made. Four species were identified: Osmoderma eremita (Scopoli, 1763), Lucanus cervus (Linnaeus, 1758), Morimus funereus Mulsant, 1862 and Cerambyx cerdo Linnaeus, 1758. Using GIS mapping analysis, the distribution of these species was established in terms of the habitats described in the Natura 2000 framework. Lucanus cervus occurred over more than half of the Prigoria-Bengeşti protected area, with an overall area of occupancy of 26.10%. Morimus funereus and Cerambyx cerdo occurred in between 23.21-27.67% of the area, whereas Osmoderma eremita only occurred in 12.04% of the ROSCI0359, with area of occupancy by 11.40%. This paper presents the threats to these beetles and summarises some management and conservation issues based on the existing observations and experience at a local level.

During 2014 and 2015, the species Morimus asper funereus Mulsant, 1862 was monitored in the Măcin Mountains National Park, Romania using the visual transect method. The studied was focused on two topics: to determine the numerical abundance of Morimus asper funereus populations and to identify the environmental variables which influenced them. Ten abiotic factors were analysed: altitude (A), exposition (Ex.), slope (S.a), forest coverage (F.c.), air temperature (A.t.), soil temperature (S.t.), air relative humidity (A.h.), cloud-cover (Nb.), wind speed (W.s.) and wind direction (W.d.). During the study period, 112 individuals were identified. The most favourable habitats for this species were Moesian silver lime woods (91Z0) and Pannonian-Balkanic Turkey oak -sessile oak forests (91M0). The main environmental variables that influenced the beetle population dynamics were the forest coverage and wind direction. Taking into account these two parameters, we concluded that Morimus asper funereus preferred semi-shaded and semi-open habitats, characteristic of mature, old, deciduous forests within the Măcin Mountains National Park. In order to protect this species, special attention must be given to the forest management measures, e.g. protection of fallen trees, abundant coarse woody debris and a dense canopy.
