Not even in autumn we are getting bored. Today, for instance, we have established an experimental biodiversity green roof intending to research and promote biodiversity in the built-up area. The basis of the vegetation cover are stonecrops (Sedum spp.), which usually form a resilient community on the shallow roof substrate. In our selection, we focused on species native to the country. The experiment also includes a regional seed mixture obtained by brush harvesting from a nearby meadow, with the addition of hand-collected seeds of local herbs. We also spread lichens over the surface to promote biodiversity and reduce the overgrowth of grasses. The lichens were used particularly in spots less suitable for growing vascular plants. Next year, we will add more elements to the roof, such as dead wood for insects. We would like to thank GreenVille s.r.o. for their collaboration in creating the roof.
After finishing the work on the roof, we visited one of the highest green roofs monitored throughout the season. To our surprise and despite the late October, scattered flowers of not only stonecrops but also spontaneously established species were still appearing due to the warm weather.
This project is financially supported by the Technology Agency of the Czech Republic.
