Caractérisation des matorrals et des garrigues à Urginea pancration Phil. dans le Djebel Tessala (Algérie occidentale)

Abstract

Une caractérisation des biotopes occupés actuellement par Urginea pancration (Steinh.) Phil. dans le Djebel Tessala entre 700 et 1000 m d'altitude est présentée. Douze parcelles ont été étudiées selon 14 paramètres écologiques dont la pente, l'exposition, l'altitude, le type de sol… Cette étude a permis de définir l'habitat biologique et édaphique de cette plante et de connaître la richesse floristique des stations qu'elle occupe sur le Djebel Tessala.Les résultats obtenus montrent qu'elle tient une place d'autant plus importante dans les matorrals et les garrigues que les conditions édaphiques sont difficiles et que la dégradation du couvert végétal est poussée.<br>A characterization of habitats currently occupied by Urginea pancration (Steinh.) Phil. in Tessala Mounts between 700 and 1000 m of altitude is presented. Twelve plots were studied according to 14 ecological parameters of which slope, exposure, altitude, soil type…This study permitted to define the biological and edaphic habitat of this plant and to show the floristic richness of the sites which it occupies in Tessala Mounts. The obtained results show that it takes up a place more important in the matorral and scrubland when soil conditions are harsh and that the degradation of vegetation cover is important

Survey phytotherapeutic use of 11 medicinal plants growing in Tessala mountains

“…Parmi ces travaux, nous citons ceux de Bouzidi et al [5] sur Urginea pancration, Bouterfas et al [6] sur Marrubium vulgare, Dif et Benchiha [7] sur Papaver rhoeas. En complément nous nous sommes intéressés à inventorier les plantes médicinales les plus utilisées dans la région de Sidi bel Abbès qui poussent dans les monts du Tessala avec indication de leurs utilisations et de leur effet thérapeutique.…”

Antibacterial Potentials of Calothrix Sp. Ndop009

“…• The PH value is moderately alkaline, it varies from 8.7 in station 6 to 8.1 in station 5, the pH is not a stable characteristic of the soil, but depends on the different cations absorbed, the nature of the plant cover and the climatic conditions (Dajoz, 1982) • Indeed the levels of organic matter are very variable, we find soils moderately rich in organic matter for stations 4, 5 and 6 and low in organic matter for stations 1, 2 and 3. Depending on the position of the stations, the amount of organic matter recorded in a station depends on the age and type of vegetation, but also on the abundance of coarse elements (Bouzidi et al, 2009) • Electrical conductivity for the study area indicates unsaline soils in all samples (C. E 0.6ms/cm).…”

Seed germination behavior of Teucrium santae Quézel & Simonneau: a vulnerable and endemic Lamiaceae (Northwest Algeria)

“…The Tessala mountains, located in Algeria's northwest, are one of the several reliefs and mountain massifs that form the country. They are known for their significant floristic richness which has been the subject of numerous studies and surveys (Bouzidi et al, 2012;Bouterfas et al, 2013;Fertout et al, 2016). Nevertheless, the impact of anthropozoogenic action and global warming have a negative influence on this specific richness, which means that many species are now threatened in their natural habitats (Saidi et al, 2016;Cherifi et al, 2021).…”
