A group of pupils from Jessen Grammar School investigates the potential spawning grounds of the native amphibians moor frog (Rana arvalis), natterjack toad (Bufo calamita), European green toad (Bufo viridis) and European tree frog (Hyla arborea) at the Steinsdorf gravel pit. The objective of the project is to record the preferences of the aforementioned species with regard to shore characteristics, depth of water, water temperature and pH value in order to achieve optimal conditions for the protection of the endangered amphibians during renaturalization. The investigation is complemented by the consideration of biotic factors such as availability of food and potential predators.
The project won the International contest of the Quarry Life Award 2014 in the category “Student Project”
