What benefits do green roofs offer cities and their residents, and how can such a project be designed and implemented—from the initial design to maintenance? Vegetation layers featuring succulents, grasses, or herbs help reduce dust, cool buildings and their surroundings, and retain rainwater. Yet a frequently overlooked fact is that green roofs can also serve as habitats for various organisms—from common to rare species. However, supporting their survival requires innovative technical solutions, suitable plant mixtures, and specific elements such as shelters, nesting structures, or substrates. During the event, we will focus on how basic extensive green roofs differ from biodiversity-focused ones. What are the structural and maintenance requirements for biodiversity-focused roofs? In what situations does their use make the most sense? These and other questions will be answered by Michal Knapp, head of the Insect Ecology Team at the Czech University of Life Sciences (ČZU) in Prague, and Pavel Dostal, vice president of the European Federation of Green Roof & Living Wall Associations.

The event is organized by the Faculty of Environmental Sciences at ČZU in Prague and the organization GreenVille service.
