LIFE AMPHIKULT 350 Ponds for Lower Saxony

Welcome to the website of the LIFEproject AMPFHIKULT which is being carried out by Lower Saxony's Nature and Biodiversity Conservation Union (NABU). We provide information on the project's background, the measures to be taken as well as news updates.

Twenty new water bodies for the European green toad

October 2014

The European green toad is the most rare amphibian species in Lower Saxony; it is classified as an "extinction endangered species".As one objective of the project AMPHIKULT, extensive measures for the protection of this species have been realized in recent weeks. At Lake Heerter in the city of Salzgitter, which marks the specie's westernmost population in Lower Saxony, seven new spawning grounds were created at the lake shore area.Up to now, only the lake itself was available as a spawning ground for the European green toad. The fish population in the lake, however, highly restricts the reproductive success. The newly created spawning grounds will likely stay free of fish in the long run since they are not connected to the lake and occasionally dry out completely.

New spawning grounds for the European green toad at Lake Heerter

In the open pit mine Treue in the Helmstedt district, six new water bodies were created, four existing ones were restored. The area was made available by courtesy of the Helmstedter Revier GmbH. Extensive open areas are still at hand in the open pit mine and could serve the European green toad as terrestrial habitat. The lack of suitable spawning grounds has thus been rectified.

In a former stone quarry in the vicinity of the Heeseberg mound which is located in the Helmstedt district as well, three more water bodies were created. European green toads have not been documented at this site for several years as there were no suitable spawning grounds. There is a chance, however, that this species might resettle the area by migrating from other populations once the water bodies to be recreated are in place.
