The aim of WP 1 is the selection of plant species - Polish and Norwegian flora - suitable for growing in the green module system (roof, walls, adjacent surroundings).
In Norway, we develop green roofs that include native plant species in the design using a habitat template approach. That means looking for natural biotopes where the environmental conditions are as similar as possible as on a rooftop. One very promising system to use elements from, is the vegetation occurring on shallow calcareous soils. They are resistant to unfavourable conditions and contribute habitats and resources for urban nature on roofs.
