A plant sociological approach for extensive green roofs in Mediterranean areas
2013
Extensive Green roofs can be an important mean for environmental mitigation if designed according to the principles of restoration ecology. Moreover, if optimally executed, properly managed and of sufficient extension, they could be assimilated to meta-populations of natural habitats, worth to be included in the biodiversity monitoring networks. The best example supporting this hypothesis is the Lake water plant Moos in Wollishofen (Zurich, Switzerland) where, on three 100 years old units of extensive green roofs, occur most of the typical flora of Mesobromion, including high density of some endangered orchid species. With this work, we propose a methodology approach for green roofs in Medi…
The Braun-Blanquet project: evaluating and characterizing European vegetation alliances
2014
European tradition on vegetation classification provides an extraordinary legacy for understanding biodiversity. However, this classification lacks explicit data on vegetation attributes, especially if we extend national or regional concepts to a continental perspective. An additional effort for evaluating and characterizing European vegetation types is therefore needed, and the data contained in vegeta tion databases are probably the main tool for these purposes. The BraunBlanquet project is an initiative of the European Vegetation Survey for characterizing veg etation alliances across Europe. By analyzing more than 500,000 vegetation plots from 22 European countries, we developed a fra…
