The core activity of the "Stiftung Pro Artenvielfalt" foundation is the promotion and protection of endangered wildlife species and their habitats. This includes in particular: land acquisition and sustainable building and biotope development; the construction of species protection buildings with nesting sites and habitats for endangered animal species; bird migration protection through international bird protection camps and campaigns against illegal bird poaching in Southern Europe; and support for wildlife rescue stations and reintroduction projects for endangered species such as fish eagles and hedgehogs. The foundation thereby pursues a comprehensive strategy for the protection and promotion of biodiversity in Switzerland and beyond.
