Jelovica, the shelter of silence Jelovica, the shelter of silence
Institute of the Republic of Slovenia for Nature Conservation Celje Regional Unit “Natura 2000 in Slovenia management models and information system” LIFE04NAT/SI/000240 project Jelovica, the shelter of silence Jelovica and Ratitovec Jelovica is a densely wooded karst plateau spreading in the eastern part of the Julian Alps. Its karst properties emerge from the area’s limestone substratum. The plateau has thus been given its special character by numerous pitches, sinkholes and caves, owing to which it is classified as a natural treasure of national concern. In the distant past, Jelovica was overgrown by beech forests which, however, have been cut down through centuries owing to charcoal burning. Today, the vast spruce forests provide shelter for numerous endangered species of birds. The plateau’s biodiversity is further enriched by montane pastures, which present an important source of food for Jelovica’s birds, and raised bogs, where specially adapted plants and animals have found suitable habitats. Extensive grasslands spread on the slopes of Ratitovec, the southern margin of the plateau. The nature-conservancy status of Jelovica and Ratitovec: • special protected area − Natura 2000 area (Decree on special protected areas (Natura 2000 areas), Official Gazette of the RS, Nos. 49/04, 110/04, 59/07); • area of ecological concern (Decree on areas of ecological concern, Official Gazette of the RS, No. 48/04); • natural asset (Regulations on stipulation and conservation of natural assets, Official Gazette of the RS, Nos. 111/04, 70/06); • the raised bogs Za blatom and Ledina are protected as nature reserves (Official Gazette of the Bohinj Council, No. 5/1999, Official Gazette of the Gorenjska region, No. 15/1999).

Geographical position of Jelovica and Ratitovec in Slovenia 2 Jelovica − friendly to birds Owing to the limited anthropological influences and the fact that the area is not populated, the fauna of Jelovica has been very well preserved. A suitable shelter has been found here particularly by several bird species that happen to be highly endangered elsewhere, which is the reason why the plateau has been included in the European Natura 2000 ecological network. The precipitous rockwalls on the plateau’s fringes are nest-sites of the Golden Eagle (Aquila chrysaetos) and the Peregrine Falcon (Falco peregrinus). The montane forests with diverse shrub layer and abundant blueberry shrubbery, including glades and montane grasslands, are the habitat of gallinaceous birds. Here, numerous woodpecker and owl Golden Eagle species can also be found, which are closely associated with forests of specific structure and age. Birds implicitly need a peaceful environment. Disturbances of different kinds, caused by humans during their activities in the forests, impede the birds’ life cycles (breeding, rearing the young, feeding, etc.), which can in turn greatly reduce their numbers. Pygmy Owl Peregrine Falcon Black Woodpecker Jelovica, as seen from Radovljica 3 Grouse birds Most suitable for the survival of these sedentary birds is forest landscape in hilly and mountainous territories. Slovenia is inhabited by several grouse species, Jelovica alone by the Capercaillie (Tetrao urogallus), Black Grouse (Tetrao tetrix) and Hazel Grouse (Bonasa bonasia). Hazel Grouse One of the trees chiselled by the Black Woo They spend the greater part of their lives on the ground, where they also nest. When performing their display calls, they like to perch in a spruce or larch. Grouse birds feed on berries as well as on buds and apices of forest trees. Woodpeckers The Capercaillie is particularly fond of older coniferous to mixed forests. Of great importance for this bird are individual forest openings with well developed herb layer, especially blueberries, cranberries and raspberries. The areas where these birds perform their courtship “dances” are called leks. In the area of Jelovica, at least 34 leks are known, at which about 50 males have been singing in the last few years. Some of them, however, have been abandoned, primarily due to disturbances caused in the woods. 4 Woodpeckers are birds that are directly associated with the dying off wood in the forests. They feed on insects living under the bark and in wood itself. When they detect the insects’ movements in the interior of a trunk, they use their powerful bills to chisel out the way to them. The forests of Jelovica are home to the largest woodpecker in Slovenia, i.e. the Black Woodpecker (Dryocopus martius). Its abandoned nest-holes are popular with numerous other breeding forest birds. The Three-toed Woodpecker (Picoides tridactylus) is one of the smaller representatives of these birds. Considering that it inhabits only coniferous montane forests with ample dying but still standing trees, it is rarer than the Black Woodpecker. Male Capercaillie at a display ground Three-toed Woodpecker Owls Owls are peace-loving birds. At night, they mark their territories with hooting or they look for suitable partners. At Jelovica, we can hear the Ural Owl (Strix uralensis), Tengmalm’s Owl (Aegolius funereus) and our smallest owl, the Pygmy Owl (Glaucidium passerinum). The Ural Owl is amongst the largest owls in Slovenia. Owing to its size, it needs big tree holes for breeding and large territory for hunting small mammals (mice, voles), smaller birds and insects, on which it feeds. Raised bog Za blatom Bogs, rare preserved wetlands Bogs, which are rare habitats in our country, are highly sensitive to any changes in their environment. This is why even more should be done to protect them against any possible detrimental influences. Bogs have been created through millennia with gradual silting and overgrowing of lakes. Apart from raised bogs, fens and transitional bogs are also known. Owing to the accumulation of peat, which is mostly composed of various peat mosses, some fens can gradually lose (in a few centuries) contact with groundwater and nutrients dissolved in it. Such fens are called raised bogs. The most characteristic raised bog at Jelovica is Za blatom. Peat moss Ural Owl The largest, called Ledina, is a transitional bog, which means that characteristics of raised bogs and fens interact here with each other. As the bog and fen grounds provide for very specific living conditions, only those plants and animals can thrive here that have adapted to this type of environment. 5 Ratitovec The southern margin of Jelovica ends with Ratitovec. Its highest peak is Altemaver, which is situated at 1,678 m a.s.l.. During the summer, the barren peaks of Ratitovec and with Dwarf-pine overgrown surrounding mountain grasslands turn into true montane pastures. Grazing prevents pastures from becoming overgrown with herbage and at the same time preserves the grasslands, which constitute a suitable habitat for the Black Grouse. Black Grouse, bird of the highest peaks This bird is the Capercaillie’s relative. The Black Grouse, too, is known for its plumage display during courting, when calling with characteristic puffing and cooing sounds. Black Grouse 6 Most important for the survival of this bird is conservation of Dwarf-pine and other dwarfish trees in the heterogeneous tree-line area, and rich herbal sites especially with Ericaceous species. Another important factor is peace in its environment particularly during the bird's display and at winter time. Jelovica - an open door to nature Within the LIFE project framework, ten information boards were set up in the area of Jelovica and Ratitovec. They help the visitors to be acquainted with the characteristics of surrounding nature in a greater detail. Furthermore, we have organised several workshops and lectures to present to the inhabitants of the area as A detailed management plan documents for the project site Jelovica, prepared within the framework of the project. well as its visitors the significance of the exceptionally well conserved nature in the area of Jelovica and of the European Natura 2000 ecological network. Within the framework of the project, we have also prepared a sample document entitled A detailed management plan for the project site Jelovica since we believe that the natural treasures of Jelovica can be preserved for future generations only with wise management.
