Through the commercial utilisation of the forests and the regulations on the stability of trees in urban areas, the proportion of trees with such nesting opportunities is decreasing. Even so-called cultural successors that have adapted to humans and nest in niches in barns, machine halls, attics or under eaves \u2013 such as swallows, sparrows or bats \u2013 are having more difficulties finding such places due to modern construction.<\/p>\n\n\n\n<p>Also, our increased need for tidiness in gardens and fields makes it more challenging for hedgehogs to hibernate because there are no piles of leaves. For ground-nesting wild bee species, it increasingly rare to find open, vegetation-free piles of sand or soil, or the edges of sloping terrain where they can lay their brood cells. The construction and maintenance of natural and artifi cial nesting aids is therefore an important contribution to the fostering of these species. There are numerous nesting aids and hibernation sites for a wide variety of animal species on the campus grounds.<\/p>\n\n\n\n<figure class=\"wp-block-audio\"><audio controls src=\"https:\/\/lehrpfad.umwelt-campus.de\/wp-content\/uploads\/2025\/09\/108_2_eng.mp3\"><\/audio><\/figure>\n\n\n\n<div class=\"wp-block-media-text is-stacked-on-mobile\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"795\" height=\"464\" src=\"https:\/\/lehrpfad.umwelt-campus.de\/wp-content\/uploads\/2025\/08\/108_4.jpg\" alt=\"\" class=\"wp-image-374 size-full\" srcset=\"https:\/\/lehrpfad.umwelt-campus.de\/wp-content\/uploads\/2025\/08\/108_4.jpg 795w, https:\/\/lehrpfad.umwelt-campus.de\/wp-content\/uploads\/2025\/08\/108_4-300x175.jpg 300w, https:\/\/lehrpfad.umwelt-campus.de\/wp-content\/uploads\/2025\/08\/108_4-768x448.jpg 768w\" sizes=\"auto, (max-width: 795px) 100vw, 795px\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<p><strong>Blue Tit<\/strong><br>Blue tit, great tit, redstart and starling need cavity nesting boxes.
