Localities were situated in the immediate vicinity of Třeboň. The total mapped area was 25 hectares. The Vegetation was dominated by tall sedges (locality New station). The principal biotops consisted of tall sedges biotop M1.7 and K1 (locality New station and locality Old station) and V1 biotop. Within Old station locality and Opatovický locality it was especially: T1.5 and T1.4 and X5. Nesting birds were counted by the mapping method (Janda a Řepa, 1989). The GPS system was used for the recording of single males. Twenty three passerine bird species were found within localities. In total, nine bird species were founded in all the localities. The most abundant species were: (Acrocephalus schoenobaenus) the Sedge Warbler, (Luscinia svecica cyanecula) the Bluethroat, (Locustella naevia) the Grasshopper Warbler (Old station locality and New station locality), Opatovický locality was dominated by Acrocephalus schoenobaenus the Sedge Warbler.
