In this article we present the impact of some forestry measures (intensity of felling, forest skidding roads) on the chosen saproxylic insects, with the emphasis on NATURA 2000 species, as well as the impact of fires on the sub-cortical fauna of the beetles (some primary saproxylic species). The study of impact of felling intensity and forest roads on the biodiversity of saproxylic beetles was done on the Omphalodo%Fagetum site on three locations (Tolmin, Novo mesto, Postojna) using cross vane funnel traps and pheromone GalloProtect 2D%. The study of the impact of fire was done on 1, 2.5, 3 years old burnt areas in the Sežana area. We found the impact of the intensity of felling in many cases had a positive effect on higher biodiversity of the species from the Cerambycidae family, but biodiversity itself depends heavily on local conditions, especially the amount of dead wood biomass. Biodiversity of sub-cortical entomofauna was the highest on the one year old location; with increasing age of the burnt areas the biodiversity was declining.

COBISS.SI-ID: 4036518The article deals with maintaining the favorable conservation status of forest habitat types and habitats of species within and outside the Natura 2000 areas. First it presents the most important forestry actions and encroachments together with the impacts they are triggering. Next, these forestry encroachments and actions are analyzed from the viewpoint of their effects. The analysis has been made on the basis of both findings from the available literature and rare national researches. The impact analysis has also presented the basis for forming good practices for management of forest habitat types, qualification plants, and animal species such as beetles and birds. Taking into consideration the fact, that momentarily there are not many data available for individual qualification species, the recommendations are general and do not refer exclusively to the species dealt with in this project. Since the effectiveness of nature conservation in addition to knowledge depends on numerous factors, for example work organization of services, cooperation of the profession with other sectors, good procedural practices, etc., in the last part of the article there are also listed some recommendations which will, in the case they are followed, most likely add to a better efficiency and higher quality of work of nature conservation and forestry as a whole.
