The Hojkovské rašeliniště – Hojkov Peatbog NNM was declared in 1982 to protect the remaining part of a peatbog with the surrounding wet meadows and waterlogged alder stands. The protected area covers an area of 4.9ha at elevations of 641-650 metres above sea level and lies around 0.6km south of the village of Hojkov, between the towns of Jihlava and Pelhřimov in the kraj Vysočina – Bohemian-Moravian Highlands Region.
The basement is built of comprises two-mica granite and porphyric adamellite of the Moldanubian Pluton. The peatbog developed around a spring emission at the head of a valley. The peat was formerly up to 3m in depth, but the depth was reduced to 1.7m during previous peat extraction. Around the Organosoils we can find Gleysols and Pseudogleysols, passing into dystric Cambisol.
The areas where peat was formerly extracted, leaving a series of pools and depressions, have gradually become overgrown with trees and developed into waterlogged tree stands, predominantly comprised of alder (Alnus glutinosa), silver birch (Betula pendula) and Norway spruce (Picea abies). Bog arum (Calla palustris) grows abundantly on the banks of the pools. An extensive growth of the critically endangered Scandinavian small-reed (Calamagrostis purpurea) can be found in the meadow enclave, and the round-leaved sundew (Drosera rotundifolia) grows in the unconsolidated sedge-sphagnum moss communities. Typical plants which grow in the neighbouring wet meadows of the Caricion fuscae and Calthion include the bogbean (Menyanthes trifoliata), marsh valerian (Valeriana dioica), broad-leaved marsh orchid (Dactylorhiza majalis), marsh willowherb (Epilobium palustre), the ragwort Tephroseris crispa and marsh cinquefoil (Potentilla palustris).
Amphibians which regularly breed in the pools include the Alpine newt (Triturus alpestris), pool frog (Rana lessonae) and common frog (Rana temporaria). Reptiles which live on the peaty meadows are the adder (Vipera berus) and the common lizard (Lacerta vivipara), while birds which can be observed here include the snipe (Gallinago gallinago), tree pipit (Anthus trivialis), meadow pipit (Anthus pratensis), grasshopper warbler (Locustella naevia) and whinchat (Saxicola rubetra).
Since 1993 the meadow has been cut by hand once a year and opportunist trees have been removed. The water regime has been modified by opening up the previously filled-in surface drainage channels and new pools have been created.
