Grünbrücken

Grünbrücken, also known as wildlife corridors or eco-bridges, are structures designed to allow animals to safely cross human-made barriers such as roads or railways. These bridges are typically covered with vegetation, mimicking the natural habitat of the animals they are intended to benefit. The primary goal of a Grünbrücke is to reduce habitat fragmentation, which can isolate animal populations, limit genetic diversity, and increase mortality rates due to vehicle collisions.

The design and placement of Grünbrücken are crucial for their effectiveness. They are often located in areas with high animal activity and where human infrastructure has bisected important migratory routes or foraging grounds. The width and vegetation cover of the bridge are tailored to the specific species that are expected to use it, with some bridges designed for larger mammals like deer and elk, while others cater to smaller animals such as amphibians, reptiles, and insects.

The implementation of Grünbrücken is a key component of ecological conservation strategies in many countries. By facilitating safe passage, these structures help maintain healthy wildlife populations and contribute to the overall biodiversity of an area. They represent a proactive approach to mitigating the impact of human development on the natural environment and can be a successful example of coexistence between infrastructure and wildlife.
