Knowledge of the diversity of the bryophytic flora of the Tafoughalt massif in north- eastern Morocco is insufficient and poorly known. The present study is the first bryological work on this massif. The bryophytic exploitation, which lasted three years (2015-2017) during periods favourable for sampling, revealed the existence of 30 bryophyte taxa, 27 of which belong to the Mosses and 3 to the Hepatica, divided respectively into 21 genders and 10 families (90%) then 3 genders and 3 families (10%). The most represented families are the Pottiaceae, Brachytheciaceae and Bryaceae. The most species rich genera are Bryum and Tortula. Four species are the most abundant in this massif, including three mosses and one liverwort:Grimmia decipiens, Orthotrichum rupestre, Pleurochaete squarrosa and Targionia hypophylla. We report the presence of two species new to the bryophytic flora of Morocco. These are Amblystegium serpens and Oxyrrhynchium speciosum. These two species are very rare in our study site according to the ecological significance index (ESI). There are five species newly observed in the region. The majority of taxa (more than 90% taxa) are saxicolous and/or terracolous.
From its Portuguese period, the historical city of Azemmour, on the Oum Errabia River banks, still boasts several monuments, including an imposing fortified wall. Among the factors of degradation that threaten this wall, we are particularly interested in the plant’s action growing over this monument. The objective was to start by establishing a list of plant species colonizing the wall, then to deduce the potential effects that vegetation can have on the substrate. We carried out a systematic sampling in Azemmour. After sampling and identifying the plants, we established a list of 58 species, belonging to 26 families and 49genera. TheAsteraceae family is the most represented with 11 species, followed by Solanaceae with 6 species, Poaceae with 5 species and Amaranthaceae with 4 species. Depending on their life form category, these plant’s roots are more or less intense, which leads to the dismantling of the masonry, and ultimately threatens ruin. The many medicinal plants found in the area are also a source of pressure on the site as they are anarchically uprooted by users. Devegetation measures must be undertaken urgently by conservators to control the spread of these plants in order to preserve the historic heritage.
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.
