Assessment of the floraTiaret. Algeria

To present day, no study has been carried out on the local flora of the Sidi Abed mountain. Situated southern the city of Tiaret considered as natural barrier before steppe area. Twenty Phyto-ecological surveys with 100 m2 Braun-Blanquet minimum area were conducted.75 species, belonging to 29 families and 66 genera has been established. Asteraceae (20%), Fabaceae (10.7), Poaceae (10.7), Lamiaceae (6.7%), Apiaceae (5.3%) and Asparagaceae (5.3) were the most representative families covering more than 50% of the inventoried families. Moreover, Therophytes (48%) are majorly dominant with a notable decrease of the phanerophytes (5.3%), and increase of Hemicryptophytes (22.7%). Predominance of the Mediterranean biogeographic type species with a percentage of (41.3%) followed by the Eur. Med (10.7%) and W Med (10.7%) typical for Mediterranean semi-arid climate. 02 endemic species were present and rarity reached 9% combined of Rare (4%) and QR (5%). Among the taxa analyzed, 08 are included in the IUCN red list with different status and 02 are on the Algerian list of protected non-cultivated species.

截至目前，尚无针对西迪阿贝德山（Sidi Abed mountain）本地植物区系的相关研究。该山坐落于提亚雷特（Tiaret）市以南，是草原地带的天然屏障。本研究共开展20次植物生态学调查，样地最小面积设定为100平方米，采用布隆-布朗克（Braun-Blanquet）样方法。经调查共记录到75种植物，隶属于29科66属。其中菊科（Asteraceae，占比20%）、豆科（Fabaceae，占比10.7%）、禾本科（Poaceae，占比10.7%）、唇形科（Lamiaceae，占比6.7%）、伞形科（Apiaceae，占比5.3%）以及天门冬科（Asparagaceae，占比5.3%）为优势科，合计占所记录科数的50%以上。此外，一年生植物（Therophytes，占比48%）为绝对优势生活型；高位芽植物（Phanerophytes，占比5.3%）占比显著下降，而地面芽植物（Hemicryptophytes，占比22.7%）占比有所提升。地中海生物地理型物种占比最高，达41.3%；其次依次为欧洲-地中海型（Eur. Med，占比10.7%）与西地中海型（W Med，占比10.7%），此类区系特征契合地中海半干旱气候的典型特点。共发现2种特有植物；物种稀有度综合占比达9%，包含稀有类群（Rare，占比4%）与疑似稀有类群（QR，占比5%）。在所分析的植物类群中，有8种被纳入世界自然保护联盟濒危物种红色名录（IUCN Red List），且保护等级各不相同；另有2种被列入阿尔及利亚非栽培保护物种名录。
