Pele Peatbog Nature Reserve
The Pele Peatbog Nature Reserve covers an overflown alluvial plain at the confluence of two forest streams, 2 km east of Chlum u Třeboně. It is an alluvial plain of two meandering streams with numerous small pools containing specific flora and fauna species. The territory like this cannot be found anywhere else in the Třeboňská Basin. The basement is formed by the medium- to coarse-grained two-micaceous granite (Číměř type) of the Palaeozoic age (Moldanubian Pluton) with two minor and shallow forest streams. Their alluvial plains are filled with thin covers of Quaternary deluvial sandy and loamy sediments which are covered in the central part of territory at the confluence of streams with the peatbog and recent sediments from the Vydýmač fishpond flooding area. The oligotrophic wetland is a site where many valuable communities live, especially the freshwater molluscs, crustaceans, spiders, mayflies, dragonflies, alderflies, stoneflies, caddisflies, etc. Also the European crayfish (Astacus astacus), ruby whiteface (Leucorrhinia rubicunda), raft spider (Dolomedes fimbriatus) and diving bell spider (Argyroneta aquatica) live here. Volunteer spruces and alders of various ages are scattered here and there and the reserve directly continues in the cultural stands with pines and spruces. The alluvial plain was drained and used as meadows in the past. Also the remnants of the water reservoir dam have preserved.
