    The greening with fatty hens ("sedum roof"), which has often been practiced so far, is species-poor and not very attractive, both for insects and for the eye.

Living roofs - species-rich and diverse

Headline

Green roofs provide a habitat for numerous animal and plant species and create ecologically valuable biotopes in urban areas. However, the potential for nature and species protection has not yet been exhausted. Many of the currently existing green roofs are not yet created to promote biodiversity. Instead, they are planted with species-poor and cultivated varieties. This leads to a low ecological value.

The aim of the project is to make better use of roof areas in the Rhine-Main region for the benefit of local biodiversity between 2019 and 2023. The Rhine-Main area with the city of Frankfurt a. M. and surrounding communities already has numerous green roofs. The region is an important growth region in which all potentials for the promotion and preservation of biodiversity should be exploited.

The urban biodiversity on roofs in this region is to be increased through model upgrading measures, the search for suitable wild plants and the testing of local wild plants. Within the framework of the compensation scheme, it is possible to use roof areas that are rich in species and varied in design to compensate for development measures and thus contribute to reducing urban heating in summer, reducing noise, improving air quality and also retaining precipitation water on the area.

In addition, the topic is to be made accessible to a broad public, public authority employees, planners and tradespeople in order to motivate owners of roof areas to create or upgrade them in a natural way.
