A critical inventory of the mediterranean endemics in the egyptian flora

In terms of plant diversity, the Mediterranean Basin is the world's second richest hotspot, and one of the most important locations on the planet for endemic species. Despite the widespread acknowledgment of the region's global importance for plant diversity, an up-to-date list of Mediterranean endemics is still unavailable. The available data are frequently insufficient or out of date at both the whole and the national levels. Therefore, the present study aimed at delimiting the Mediterranean floristic region, screening the Mediterranean endemics, and determining the habitats and phyto-geographical distribution of these taxa in Egypt. Hence, a preliminary list of 402 Mediterranean endemic taxa in Egypt was compiled from the available literature. Indeed, the present study has reduced this number to sixty-five (16.2%) Mediterranean endemics belonging to 49 genera and 22 families. Fifteen major habitats are supporting the Mediterranean endemics in Egypt. The most represented habitat was the non-saline depressions (20 taxa = 30.8%), followed by the coastal dunes (19 taxa = 29.2%). Moreover, the Mareotis (west) subsector was the richest with 57 taxa = 87.7%. In conclusion, it's crucial to clearly define Mediterranean endemic plants and provide an updated documented database of these taxa for a given territory to help guide future management plans that support the conservation and sustainable use of these important species under the current thought-provoking devastating impacts of rapid anthropogenic and climate changes in the region.

Automated summary

The Mediterranean Basin is the world's second richest hotspot for plant diversity and an important location for endemic species. However, there is currently no up-to-date list of Mediterranean endemics. This study aimed to create a preliminary list of Mediterranean endemic taxa in Egypt and determine their habitats and distribution.
