With an estimated < 50 adult individuals remaining, the Critically Endangered Balkan lynx Lynx lynx balcanicus is one of the rarest, most threatened and least-studied large carnivores. To identify priority conservation areas and actions for the subspecies, during 2006–2014 we conducted 1,374 questionnaire surveys throughout the potential range of the Balkan lynx to (1) evaluate human–lynx interactions and identify potential threats, and (2) determine the probability of site use in 207 grid cells through occupancy modelling. Human–lynx interactions were related mainly to poaching of lynx, and damage to livestock by lynx. Poaching was intense throughout the potential range of the subspecies, apparently having affected 50–100% of the total estimated extant population. Damage to livestock was recorded only in relation to sheep, mainly in the southern part of the lynx's potential range. Occupancy modelling indicated 108 grid cells with high probability of site use, which was affected mainly by increased terrain ruggedness and reduced forest cover. Based on the combined results of our study we identified five priority areas for conservation, as well as in situ habitat protection, community participation in the conservation of the subspecies, and the improvement and implementation of the existing legal framework as the priority conservation actions for the Balkan lynx.

Spatial and foraging ecology of the Eurasian lynx (Lynx lynx) has been well recognized, however due to the distinct taxonomic position and geographic isolation of its Balkan population, it is important to learn and compare its ecology to other populations of this felid. Therefore, the paper offers the first ever investigation into the spatial and foraging ecology of this predator. To that aim, we used modern GPS/GSM telemetry methods, allowing proper research of animal spatial requirements and diet preferences. Individuals were captured using walk-through, double-door box-traps and foot-snares placed on fresh lynx kills. Average home range size of males is 373 km2 (95\\% MCP) and 400 km2 (0.7 Kernel), while the female’s home range is 119 km2 (95\\% MCP) and 108 km2 (0.7 Kernel). GPS clusters showed prey remains of 153 kills from five different species: roe deer, chamois, brown hare, red fox and marten. Data collected for the Balkan lynx suggest lower kill rates, probably associated with lower ungulate densities in the study area compared to most of Central Europe, also indicated by the relatively long search time. Although Eurasian lynx can adapt to lower ungulate prey densities by increasing hunting effort, changing spatial organization or switching to smaller prey, this, in turn, can have adverse demographic effects on the critically endangered Balkan population. Using GPS telemetry, we provided first insight into the space use of this small population, and show that the spatial and foraging ecology of the Balkan lynx appear similar to other European populations of this species, especially those from Central Europe with similar home range size and principal prey preference.

The King of the Forest: Local Knowledge About European Brown Bears (Ursus arctos) and Implications for Their Conservation in Contemporary Western Macedonia
2011
From a conservation point of view, Macedonia’s brown bear (Ursus arctos) population appears to be a key link in the distribution of one of Europe’s largest brown bear populations, the Dinaric-Pindos population. The lack of information concerning the bear population in the Republic of Macedonia and bear acceptance by local people inspired us to explore local knowledge and perceptions concerning bears that could be relevant for their conservation. Accordingly, we adopted a qualitative approach using semi-structured interviews to determine how the specifi c behaviour and ecology of bears can infl uence, through interactions, local peoples’ knowledge and perceptions. Our results show that due to numerous interactions, the informants’ knowledge appeared to be detailed and consistent, both internally and with existing scientifi c literature about bears. Bear specifi c behaviour allows them to be located, individualised and thus appropriated by villagers, and also to be identifi ed as an alter-ego. For the villagers, the occasional harmfulness of a bear is not the result of a general characteristic of bears in general, but of some individual bear’s behaviour. Finally, bears enjoy a relatively good image as long as local people can react against individuals that cause damage. However, direct or indirect poaching of bears is still a main concern for the Macedonian brown bear’s conservation

The remnant population of Balkan lynx Lynx lynx martinoi is small, isolated and highly threatened. Since 2006 a conservation project has surveyed its status and promoted its recovery in Albania and Macedonia. Eurasian lynx are often associated with conflicts of an economic or social nature, and their conservation requires a focus on the people sharing the landscape with the species. In this study we adopt methods and conceptual frameworks from anthropology to explore the local knowledge and perceptions of lynx among rural hunters and livestock breeders in the western mountains of the Republic of Macedonia in south-east Europe. The main finding was that local people rarely saw or interacted with lynx. As the level of interactions with this species is very low, the lynx doesn’t appear to be a species associated with conflicts in Macedonia. There was also a general lack of both scientific and local knowledge, which has led to somewhat negative attitudes, mainly based on myths and rumours. Poaching of lynx and their prey seem to be the main barriers to lynx conservation.

Important Bird Areas in Macedonia: Sites of Global and European Importance Identification of the Important Bird Areas (IBAs) is an initiative implemented by BirdLife International at the global level, aiming to conserve a network of sites that are particularly important for the conservation of birds. With the changed conservation status of some species and increased information on the distribution and population sizes of birds in Macedonia in general, a revision of the IBA network was needed to update previous inventories for this country, published in 1989 and 2000. As the bird fauna of the Republic of Macedonia ranks among the least known in Europe, and as data on many species, notably passerines, are still largely missing, the inventory is mainly based on some threatened or rare birds of prey and a few other larger species, yet characteristic of the Macedonian landscape. Data used were collected in the course of different dedicated studies and projects carried out after 2000. Out of 314 species so far registered in Macedonia, 114 regularly occurring species have currently unfavourable conservation status in Europe, 84 of which breed or possibly breed in the country. Several criteria for the selection of IBAs of global (A criterion) and European importance (B criterion) developed by BirdLife International were used for sites selection, taking into consideration species of global conservation concern (A1), biome-restricted species (A3), important congregations (A4, B1) and species with an unfavourable conservation status (B2) or concentrated (B3) in Europe. Species of global conservation concern used for site identification include the Egyptian Vulture [Neophron percnopterus], considered Endangered (EN) at the global level according to the latest IUCN Red List of Threatened Species, Dalmatian Pelican [Pelecanus crispus] and Imperial Eagle [Aquila heliaca] (both Vulnerable - VU), and Roller [Coracias garrulus] and Semicollared Flycatcher [Ficedula semitorquata] (both Near Threatened - NT). Furthermore, species assemblages characteristic as occurring mostly or entirely within a Eurasian high-montane or Mediterranean biome are found in Macedonia. Important congregations of non-breeding waterbirds with at least 1% of global or biogeographic populations of individual species occur on all three large lakes in the country, some of them (e.g. Dalmatian Pelican, Red-crested Pochard [Netta rufina]) in very large numbers, surpassing the 1% threshold by more than tenfold. In total, 25 species regularly occurring in the breeding season, for which the site protection approach is thought to be appropriate in Macedonia, were used for the selection of sites of European importance. Site boundaries were drawn following distinct natural features or isohypses to include breeding sites and foraging areas of triggering species, and, for Imperial Eagle and Egyptian Vulture also former breeding sites back to 1991, taking into consideration their habitat requirements, land-use and management needs. The resulting IBA list numbers 24 sites, covering 6,907 km[2] or 26.9% of the entire territory of Macedonia: (1) Sar Planina Mountain, (2) River Radika Catchment, (3) Lake Ohrid, (4) Lake Prespa, (5) Demir Kapija Gorge, (6) Lake Dojran, (7) Zletovska River Valley, (8) Tikves Region, (9) Pcinja - Petrosnica - Kriva Reka Rivers, (10) Preod - Gjugjance, (11) Osogovo Mountains, (12) Jakupica Mountain, (13) Taor Gorge, (14) Ovce Pole, (15) Topolka - Babuna - Bregalnica Rivers, (16) Gradsko - Rosoman - Negotino, (17) Lake Mantovo and Kriva Lakavica River, (18) Raec River Valley, (19) Pelagonia, (20) Mariovo, (21) Lake Tikves, (22) Bosavija, (23) Kocani Rice Fields, and (24) Lower Vardar. With the exception of three sites occupying the highest parts of the large mountain massifs in NW and central parts of Macedonia, and the lakes Ohrid and Prespa, sites are concentrated mostly in central hilly and lowland parts of the country, comprising breeding areas of species of global conservation concern. The percentage of territory covered by the IBAs in Macedonia is relatively high compared to the total European average but comparable to several countries in SE parts of Europe. The size of separate IBAs ranges from 25 km[2] (Taor Gorge) to 1,136 km[2] (Pelagonia) and number of triggering species per site from one (Bosavija, Kocani Rice Fields) to 17 (Pcinja - Petrosnica - Kriva Reka Rivers). 22 sites trigger some of the criteria of global importance - three sites (Lakes Ohrid, Prespa and Dojran) meet A4 criterion, eight sites hold significant populations of species characteristic of the Mediterranean biome, while three other sites sustain significant populations characteristic of the European high-montane biome. Species of global conservation concern are included as follows: Egyptian Vulture on 13 sites, Imperial Eagle on 7, Dalmatian Pelican and Saker Falcon [Falco cherrug] on 2, Ferruginous Duck [Aythya nyroca] on 3, Roller [Coracias garrulus] on 10, Red-footed Falcon [Falco vespertinus] on 3 sites, and Semi-collared Flycatcher on 1 site. Individual triggering species for sites of European importance are represented on 2-15 sites. The IBA network includes 80-100% of the national populations of the globally threatened species, while the coverage of other species vary between 5% and 100%, being over 40% in great majority of species. Non-irrigated arable land and transitional woodland-shrub are dominant land-cover types, jointly covering 32% of the total IBA surface area. Abandonment of traditional pastoral system, resulting in decrease of the livestock numbers and overgrowing as well as trapping, poisoning and poaching, are considered the most serious threats for triggering species, particularly the Egyptian Vulture and Imperial Eagle, being classified as high on no less than 11 sites, respectively. The national legal protection of the sites is incomplete, being either only partial or with inadequate conservation measures adopted, or, many sites still lack any form of legal protection. With about 21% of the National protected area network overlapping with the IBAs, the existing protected area system is thus insufficient for conservation of most priority species. Notably underrepresented are the regions in the lower parts of the country with the highest number of species of global conservation concern.
