The Novodomské rašeliniště NNR was declared in 1967 on a total area of 574.8 ha, of which 185.9 ha forms the buffer zone. The NNR lies NW of the town of Chomutov in the Ústecký kraj - Ústí nad Labem Region, on the Krušné hory mountain peneplain at elevations of 810 to 830 metres above sea level.
The subject of the protection is a watershed peatbog complex with powerful springs of underground water, which consists of two separate peatbogs – the Načetínské and Jezerní peatbogs. These two bogs are joined by waterlogged and peatbog spruce communities and a range of typical flora and fauna are bound to these biotopes.
The NNR territory is built of the rocks of the Krušné hory Crystalinicum, which range from older grey gneisses of Proterozoic age and younger red gneisses of Upper Proterozoic to Lower Paleozoic age. The grey gneisses are represented by biotite paragneiss and the red gneisses by two-mica orthogneiss. The weathered gneisses are covered by a thick layer of Quaternary organic peaty sediments up to 7 metres in depth.
Extensive pine scrub growths - Pinus x pseudopumilio are typical for the reserve and their growths have maintained a natural composition and considerable biodiversity in places. Typical peatbog species in the undergrowth include labrador tea (Ledum palustre), dwarf birch (Betula nana), marsh andromeda (Andromeda polifolia), round-leaved sundew (Drosera rotundifolia), the cranberry Oxycoccus palustris and crowberry (Empetrum nigrum). Extensive growths of hare’s-tail cottongrass (Eriophorum vaginatum) can be found in more areas. Some very large Carpathian birch trees (Betula carpatica) can be found around the fringes of the reserve. The non-indigenous and undesirable prickly spruce (Picea pungens) was planted around the fringes of the reserve in the past.
The fauna of the Novodomské peatbogs is of typical mountain forest species and significant bird species in the area include black grouse (Tetrao tetrix), Tengmalm’s owl (Aegolius funereus), pygmy owl (Glaucidium passerinum), hen harrier (Circus cyaneus), crossbill (Loxia curvirostra) and occasionally cranes (Grus grus) can be seen here. The capercaillie (Tetrao urogallus) was an inhabitant of the reserve in the past but its presence has not been documented recently. The invertebrate fauna which is bound to the peatbog biotypes is also of great significance.
Previous drainage work of the peatbogs had a considerable negative effect on the development of the reserve. This drainage work negatively influenced the pine scrub growths as well as the surrounding forest complexes. Some of the surrounding forest stands still display evidence of the air pollution load in Krušné hory dating from the 1970s to the 1990s.
Novodomské rašeliniště NNR is included in the Novodomské rašeliniště – Kovářská SPA – Bird Area and also the proposed Novodomské rašeliniště – Polské rašeliniště Site of Community Importance.
The subject of the protection in the SPA – Bird Area, the black grouse is currently being researched into the vascular plants and invertebrates in the NNR, but we are planning to install large information panels around the borders of the reserve and possibly build a viewing tower.
