The species is known from several localities, three of them located on the territory of Galicica NP, and one in Jasen nature reserve, which is also a protected area.The total number of recorded individuals is about 120. The other sites are not protected and the habitats are under anthropogenic pressure. The impact is manifested by host habitat degradation and/or fragmentation in view of the fact that the species is strictly bound to a single host. Fires during summer season pose another serious threat. Nevertheless, the Macedonian oak community has broader distribution in the country; hence, the predicted number of individuals would be approximately 500. АОО is 24 км2 but it also includes sites with well-developed Macedonian oak communities, which are more common, and where the species is expected to occur.


Current population trend



Daedaleopsis nitida is a rare species, occurring with different abundance at all localities where the host is present (the Macedonian oak) but it is more common in the well-developed Macedonian oak communities, particularly if there are old trunks around. The best community of Macedonian oak is located within Galicica NP, where the majority of Daedaleopsis nitida specimens have been collected (approximately 100 specimens). At the remaining sites, individual specimens have been observed, and the total number of specimens is about 120. Nevertheless, the Macedonian oak community has wider distribution in the country; thus, the projected number of specimens would be approximately 500.

Habitat and Ecology

Daedaleopsis nitida is a rare species, growing as a saprobe on old trunks, branches and snags of Quercus spp. It causes white rot on dead wood of oak. It is known from almost all countries in the Mediterranean, where Quercus ilex is the most common host. It has also been reported from other hosts, as follows: Quercus ballota, Q. coccifera, Q. rotundifolia, Q. suber, Q. cerris and Q. pubescens (Saita 2010).

In N. Macedonia the species has been spotted on old trunks of Macedonian oak (Quercus trojana). The Quercus trojana habitat is typified by a separate forest phytocoenoses Quercetum trojanae, primarily developing in the northern, south-western and western parts, in the height belt of 300 to 900 m. The sites where the habitat occurs are parts with refugial forest vegetation where this species i.e. azonal forest community retracts under the pressure from the recent zonal forest climatogenic communities. Macedonian oak forests in the Habitats Directive are specified as: 9250: Quercus trojana woods, Pal. Class: 41.781Helleno-Balkanic Trojan oak woods. Despite the fact that there are data that the species also occurs on the oaks Quercus pubescens and Q. cerris, which are very common in our country, there are not any confirmed findings of Daedaleopsis nitida yet.

Use and trade

Use and trade

There is no confirmed use and trade of this species in N. Macedonia.



The impact is manifested by host habitat degradation and/or fragmentation in the light of the fact that the species is strictly linked to a single host. Immediate impact upon the species has not been established. The presence of D. nitida in old growth forests belonging to natural protected areas highlights the species fundamental role in decay of wood material in habitats subjected to minor anthropogenisation. The threat manifests differently, and it depends on the community site but fires during summer season could pose another severe threat.

Conservation actions

Conservation actions

Protection of old host trees is the key conservation action for protection of the species; study of the population number and range; interpretation of species status by means of enhanced understanding of the species biology and ecology; habitat conservation; study of the trends via monitoring.
