New insights on the conservation status of the Endangered coastal endemic plant Astragalus berytheus (Fabaceae) in Lebanon

Abstract

Coastal vegetation includes unique species with adaptations to the specific conditions of this environment, and in the Mediterranean region urban development of coastal areas has severely affected coastal ecosystems. Astragalus berytheus Boiss. & Blanche is a narrow endemic plant of the eastern Mediterranean coast, occurring in Lebanon and Palestine/Israel; its Red List status has not been previously assessed. As a result of the effects of urban sprawl in coastal areas A. berytheus is one of the most threatened plant taxa in Lebanon. We assess the conservation status of this taxon and propose conservation measures. Only one population of A. berytheus is extant in Lebanon, in the Tyre Coast Nature Reserve. We recommend that A. berytheus should be categorized as Endangered globally and as Critically Endangered at the national level in Lebanon. Unless adequate conservation measures are implemented A. berytheus is likely to go extinct in Lebanon in the near future.

Identification of plant micro-reserves using conservation units and population vulnerability: The case of an endangered endemic Snowflake (Acis nicaeensis) in the Mediterranean Basin hotspot

“…It is therefore often necessary to build a more local and smaller-scale approach to preserve rare species. Despite the importance of the urbanization phenomenon for the alteration of Mediterranean biodiversity and ecosystem service supply (Garci ́a-Nieto et al, 2018), very few studies examine the consequences of these impacts and the possibilities of mitigating the induced effects on rare plants (e.g., Lhotte et al, 2014;Sulis et al, 2020;Abdel Samad et al, 2021).…”
