État de la populationExpert
The population is not severely fragmented although the subpopulations are scattered between different summits of the Mount Lebanon and Anti-Lebanon mountain ranges. These distances constitute an obstacle to gene flow. Moreover, the Beqaa plateau also constitutes an important obstacle to gene flow between the two mountain ranges.

There is no information on population trends in this species, however, a decline is suspected based on known trends in habitat extent and known threats.

Description complète des menacesExpert
Gagea micrantha is considered to occur in nine locations.

Over-grazing is the most widespread threat in both the Mount Lebanon and Anti-Lebanon mountain ranges. It leads to the deterioration of the habitat quality, destroys the aerial parts of the plants preventing seeds dissemination, and jeopardizes the durability of the species. The density of flocks grazing in the region of Mount Lebanon mountain range was recently accentuated by the Syrian conflict as many shepherds usually summering in the Anti-Lebanon came to the plateaus of Mount Lebanon instead.

On the plateaus of both mountain ranges, the construction of roads and the use of off-road vehicles for recreational activities constitute a threat to the species as it destroys its natural habitat. The creation of a ski resort has importantly affected the natural habitats and the plant communities on some parts of the plateau of Mount Makmel. Further developments of the resort for the expansion of the pistes may occur in the future and threaten the habitats of the species.

In the case of the location of Mount Hermon, the situation is a bit different as it is considered as a secured area with limited access and even the shepherds are not allowed access to the higher altitudes slopes. Therefore, it is plausible that the species is less threatened there than anywhere else in its distribution range.

Climate change should also be considered as a future threat that could severely affect the whole range of the species with drought events and declines in volumes and duration of snow-melt (Medecc 2019).

Mesures de conservation recommandéesExpert
The species is apparently present in the Chouf Biosphere Reserve in Lebanon.

There is a need to document known subpopulations to enable an informed assessment of the conservation status of this species. Conservation actions should be carried out to protect the habitat of the species. As for many endemic plant species, national regulations should be implemented along with education and awareness. Ex situ conservation is also needed to conserve the genome of the species. The species was previously assessed as Data Deficient (Lansdown 2016).
