Effect of different restoration approaches on two species of newts (Amphibia: Caudata) in Central European lignite spoil heaps

摘要: Abstract Post-mining sites often offer secondary habitats for various amphibians endangered in common agricultural landscapes. On the other hand, there is a general lack of quantitative studies on effects restoration practices colonisation such artificial freshwater by amphibians. Here, we focus two newts decreasing Central Europe, Lissotriton vulgaris and Triturus cristatus, pools within lignite (brown coal) spoil heaps western Czech Republic. We compared their abundances established technical reclamation, spontaneous succession, combination. In spring 2016, sampled 29 five 10 fishponds surrounding landscape funnel trapping. captured 52 L. 138 T. cristatus all studied together. As only no were caught fishponds, high potential post-mining landscapes was confirmed. Both newt species generally avoided artificially pools, but spontaneously equally suitable them both technically reclaimed developed heaps. preferred more transparent water, higher cover cattails pool placed forest, with fewer trees banks, whilst narrower zone littoral vegetation, smaller water bodies absence fish. Such habitat preferences fully corroborate natural habitats. The reclamation still prevails many regions. reveal it an unsuitable practice amphibians, if not combined succession processes.
