Increasing the resistance of Mediterranean extensive green roofs by using native plants from old roofs and walls
| Resumo: | While the use of extensive green roofs (EGRs) is increasing worldwide, Mediterranean conditions complicate EGR design due to their long, dry summers with intense solar radiation. Aim: To inform sustainable EGR design for Mediterranean regions, we explored the use of resilient, droughttolerant species in experimental EGRs. Methods: We selected four native species that are known to spontaneously establish themselves on urban structures, including roofs, in Lisbon, Portugal: Antirrhinum linkianum, Asphodelus fistulosus, Centranthus ruber, and Sedum sediforme. We evaluated growth and aesthetic value under two irrigation treatments (100 and 60% ETo, reference evapotranspiration). The presence of moss covering for the lower level of irrigation was also evaluated. |
