The vegetation and flora of 86 sacred sites (surroundings of tombs of local saints, cemeteries) in NW Morocco was studied to assess their conservation value for undisturbed Mediterranean evergreen forests and vulnerable plants. Habitats were mapped, based on life form, maximum height and cover value, and classified according to naturalness. Vascular plants were classified according to pre‐defined risk factors like stenochory or grazing sensitivity. Naturalness index and refugial value were calculated for each site. Only 20% of the mapped site area was closed forest. On many places, human impact had created a vegetation mosaic. Most of the vulnerable plants were mesophilous forest species or grazing sensitive taxa. Endemic species occurred only rarely. The occurrence of vulnerable plants and the naturalness of the vegetation were positively correlated. Sacred site extension had no significant effect on the number of vulnerable species. Results indicate a limited relevance of sacred sites in northern Morocco for the protection of intact forests and vulnerable plants. However, these localities can play an important role as stepping stones in agricultural landscapes. They protect plants, sensitive to opening of the tree layer, to deforestation and to intense grazing. Certain formerly widespread forest communities survived exclusively on sacred sites.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
