This work aims to identify plant species populating Lixus in order to determine the biodegradation on building rocks. Lixus is located, on the right bank of Lokkous River in Tanger-Tétouan region. A systematic inventory was established all around the monuments and the neighbouring quarry. In fact, 92 species have been recorded belonging to 33 Families of superior plants. The best distributed are the Palmaceae (Chamaeropshumilis) and the Anacardiaceae (Pistacia lentiscus) with a rate of distribution reaching 100%,followed by the Oleaceae(Olea europaea), with 83,3% as a distribution rate. In the other hand, the families presenting the largest numbers of species are the Poaceae and the Asteraceae with 21 and 18 species respectively. All the surveyed species were classified according to Raunkiaer 1905; 1934 and Fennane 1999; 2007; 2015, those belonging to therophytes and hemicryptophytes are the most representative with 45% and 27% respectively. This study confirms that Lixus belongs to the psammophile ecologic group.
Generally, the presence of plants on building rocksindicates the presence of water in the cracks of materials and particularly reflects a lack of maintenance. The degradation effect of plantsincreases with calcareous rocks, accentuating the phenomenon of dissolution, therefore generating asurface disintegration.Thus, the volume of roots explode the walls and create deep cracks. Besides algae, fungi and bacteria, the crustaceous Lichens covering the walls are the most invasive and destructive they form visible deposits that generateaswell a disaggregation and an unsightly appearance to the rocks. The plant diversity recorded bythe big exposure of those building rocks to biodegradation recommends adequate measures to preserve building rocks from the action of the plants, using methods of mechanical and chemical cleaning, in order to limit the action of biodeterioration of the built heritage.
