At an on-site meeting between the SOCIAL-NATURE project manager and the biologist Oliver Fox, a surprise awaited her: another species relying on quarries as a secondary habitat in Saxony - the natterjack toad. "The population of the natterjack toad is shrinking in many areas, but it finds ideal conditions in quarries," says project manager Walter. It is part of this species' strategy to spawn in small, shallow waters. These warm up quickly, accelerate the development of the tadpoles and are free of predators such as fish and dragonfly larvae. The disadvantage, however, is the risk of the water drying out.
This frequently occurring aspect of nature also appeared at the spawning habitat in Penig: the young tadpoles threatened to dry up. The operator of the mining site was asked to supply the spawning area with additional water via wheel loader. "This is another example of how we can work together to protect species in mining sites," said Stefanie Walter, the project manager, thanking the staff involved.
