Despite temperatures of almost 30 °C, a group of eight students accompanied by Anna-Lena Vollheyde set off for Pattensen on 19 August 2020. Equipped with plenty of water, sunscreen, sturdy shoes, long trousers and folding rulers, the group supported Nina Lipecki from the "Feldhamsterland" project in mapping the rodent threatened with extinction. Keeping their eyes on the ground, the group systematically walked stubble fields, looking for entrances to burrows and pitfall tubes. In the process, the students learned a lot about the way of life of the field hamster and which measures can contribute to the protection of the animal, especially in the field of agriculture. The highlight of the day for all was the sighting of a field hamster. It was worth the sweat!
