Jazevčí National Nature Reserve

The Jazevčí NNR covers a territory of 99.2 ha with a buffer zone of 252.4 ha at elevations of 340 – 375 metres in the parishes of Javorník and Nová Lhota, and lies in the eastern tip of the Jihomoravský kraj – South Moravian Region and on the territory of the Bílé Karpaty Protected Landscape Area.

The reserve covers a complex of herb-rich meadows above the left bank of the Velička river (Jamný potok) on the north-eastern slopes of Hradisko hill (636 m) between Suchovské mlýny mills and Javorník. Jazevčí is a territory of herb-rich meadows with great landscape value and numerous protected and animal species.

The geological basement is formed of layers of calcareous claystones, marlstones and calcareous sandstones of the Bílé Karpaty unit of the Magura Flysh. The main soil types are typical Cambisol and Pseudogleyic Cambisol, with Fluvisol along the bank of the Velička river.

The gentler slopes are covered with thermophilous grassland communities with the erect brome-grass (Bromus erectus) heath false-brome (Brachypodium pinnatum). Many rare and protected herbs grow here, including 10 orchid types. Among the most significant are the heath spotted orchid variety (Dactylorhiza maculata subsp. transsilvanica), bumble-bee orchid (Ophrys holosericea) and the pyramidal orchid (Anacamptis pyramidalis). Other orchids with a scattered distribution in the reserve are the early purple orchid (Orchis mascula), military orchid (Orchis militaris), fragrant orchid (Gymnadenia conopsea subsp. conopsea), lesser butterfly orchid (Platanthera bifolia), elder-flowered orchid (Dactylorhiza sambucina) and the globe orchid  Traunsteinera globosa.

Other notable plants on the meadows are the gladiolus - Gladiolus imbricatus, Hungarian iris (Iris variegata), grass-leaved flag (Iris graminea), large pink (Dianthus superbus), cross gentian (Gentiana cruciata) and the bellflower Campanula cervicaria.

Small wetland communities have formed around the spring resurgences with hard rush (Juncus inflexus)and other species including western marsh orchid (Dactylorhiza majalis), adders tongue (Ophioglossum vulgatum) and brown galingale (Cyperus fuscus). Snowdrops (Galanthus nivalis) bloom on the meadow margins and in the forest in the spring and among the shrubs we can find Cornelian cherry (Cornus mas).

Among the many bird species which nest on the NNR territory are the corn bunting (Miliaria calandra), barred warbler (Sylvia nisoria), corncrake (Crex crex), quail (Coturnix coturnix), wryneck (Jynx torquilla), great grey shrike (Lanius excubitor), red-backed shrike (Lanius collurio), whinchat (Saxicola rubetra) and stonechat (Saxicola torquata) as well as the golden oriole (Oriolus oriolus).

The slowworm (Anguis fragilis), yellow-bellied toad (Bombina variegata) and common frog (Rana temporaria) can be found in the forests and around their fringes. Several rare species of Geometridae also occur on the territory. Phytophagous beetles include the weevil Alophus weberi, the flea beetle Longitarsus brunneus, the leaf beetle Cassida ferruginea, the Ceutorrhynchid beetle Mogulones larvatus and others. A total of 16 Orthoptera species have been documented here as well as 16 ant species and 4 types of social wasps.

Regular cutting of the grasslands is essential to maintain vegetation in good condition. The meadow areas which are inaccessible for machinery were previously abandoned and began to be overgrown by opportunist woody species, especially in the north-east of the NNR territory. In the late 1980s more than 15 ha were cleaned of these tress and shrubs and are now regularly cut. We are preparing to implement extensive sheep grazing on the steepest slopes.
