Surveying and mapping cereals and legumes wild relatives in Mount Hermon (Bekaa, Lebanon)

Abstract

Abstract Crop Wild Relatives (CWR) should be highly prioritized, monitored, and conserved as they have an immense effect on sustainability and livelihood. In this study we aim to survey and map cereal and legume wild relatives of Fabaceae and Poaceae families. Mount Hermon, Bekaa side, Lebanon. A set of 46 CWR species were targeted based on desk selection analysis and prioritization by the International Center for Agricultural Research in Dry Areas genebank for their potential importance in breeding programs. A botanical survey of 17 sites of the various habitats of Mount Hermon was performed during April–June 2021 using a systematic transect/quadrate sampling method. Recorded genera and species were accurately georeferenced and then mapped with the DIVA‐GIS program. In total, 854 occurrences were observed belonging to 34 species of Fabaceae and 12 species of Poaceae. High H′ Shannon diversity values were recorded in three sites (Al Fakiaa, Sham El Hafour and Ain Ata‐ al Berke) of the Mount with values ranking between 2.45 and 2.83. This was confirmed by the richness distribution maps of genera and species. Richness distribution maps provide relevant clues on candidate sites for high concentrations of each of the species under study. At least the three sites, hosting 87% of the surveyed CWR's species, can be considered for further in situ conservation actions.
