الوضع الحالي للتركيب الفلوري في وادي الدكر بمدينة زليتن -ليبيا

Abstract

The current study addressed the current floristic composition in Wadi El Zekr, Zliten City, Libya. Through six field trips, a total of 30 randomly located stands, each of 10 m², were sampled. In each stand, a complete list of all species with their updated taxonomic families and life spans was recorded. A total of 86 species belonging to 80 genera and 35 families were recorded in Wadi El-Zekr, Zliten City, Libya. Four families (Asteraceae, Fabaceae, Lamiaceae, and Poaceae) were the leading families, collectively contributing 44.19% of the total number of surveyed species. The surveyed species were distributed into 47 annuals and 39 perennials. Concerning life-forms, the surveyed species are distinguished into 45 therophytes (52.33% of the total recorded species), 12 hemicryptophytes (13.95%), 11 phanerophytes (12.79%), 10 chamaephytes (11.63%), and 8 geophytes (9.30%). The biregional elements had attained the highest contribution by 31.40% (27 species), followed by monoregional elements (26 species = 30.23%), worldwide taxa (18 species = 20.93%), and pluri-regional taxa (13 species = 15.12%). Furthermore, the Mediterranean chorotypes are represented by 55 species (64% of the total recorded species in the study area), while Saharo-Sindian, Irano-Turanian, and EuroSiberian elements are represented by 29, 20, and 9 species, respectively.
