Kingdom Phylum Class Order Family
PLANTAE TRACHEOPHYTA MAGNOLIOPSIDA ASTERALES COMPOSITAE

Scientific Name: Hieracium lucidum
Species Authority: Guss.

Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(i,ii,iii,v)+2ab(i,ii,iii,v) ver 3.1
Year Published: 2006
Date Assessed: 2006-01-31
Assessor(s): Gianguzzi, L. & La Mantia, A.
Reviewer(s): Strahm, W. & de Montmollin, B. (Mediterranean Island Plants Red List Authority)
Justification:
Listed as Critically Endangered because of the extremely limited area in which this species is found, which is estimated to be 0.2 km². The actual population may only cover as little as 800-1,200 m². Calculations based on these figures estimate that there might only be about 400-500 individuals.

Geographic Range [top]

Range Description: This plant grows exclusively on Mt. Gallo near Palermo, in northwestern Sicily. It is found in only three locations representing just one subpopulation in a tiny area.
Countries:
Native:
Italy (Sicilia)

Population [top]

Population: It is not easy to estimate the number of individuals because of the inaccessibility of its habitat. There might be 400-500 individuals in the population.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This perennial herb grows on northern slopes of calcareous maritime cliffs exposed to humid winds. These sites are rich in nitrates from sea bird droppings.

H. lucidum only reproduces from seeds. It is a typical example of a plant which grows in rock crevices and on rock faces. It belongs to a genus containing many very similar-looking species, which presents identification difficulties to the non-botanist (and even many botanists)! The species is very similar to Hieracium cophanense.
Systems: Terrestrial

Threats [top]

Major Threat(s): The threats to this species are not sufficiently understood, although in theory its inaccessibility should provide protection. However as the population occurs close to an inhabited area, its close proximity to human activities increases the risk of extinction and fire may also pose a threat.

Conservation Actions [top]

Conservation Actions: Actions in Place
Legally: Though this species is included in the regional and national Red Lists, it is not protected by any particular law or convention.

In situ: The population occurs in the "Capo Gallo" Nature Reserve and SIC (Site of Community Importance) of "Capo Gall" (ITA020006). This implies that collection of wild specimens is prohibited, grazing is regulated, and no quarrying is allowed.

Ex situ: Seeds are conserved in the germplasm bank of the Department of Botanical Science of Palermo University, and plants are cultivated in the botanic gardens of Palermo and Catania.

Actions Needed
Fire management is key to the survival of this species and the preservation of the landscape of the nature reserve. Whilst fire is essential for some Mediterranean species which have co-evolved with fire and require it to survive, the increased frequency of human-made fire may pose a problem even to these plants and emphasises the importance of a carefully designed fire management scheme for the area.
