Red List Category & Criteria: Critically Endangered A2cd; D ver 3.1

The tree is limited to the Madonie Mountains in the north-central part of Sicily, Italy. There are 30 mature trees in the current population. This very small population size means that it still meets the criteria for listing as Critically Endangered under Criterion D, and under criteria A (A2cd) on the basis of past population decline.
Previously published Red List assessments:
2006 Critically Endangered (CR)
1998 Endangered (E)
1998 Critically Endangered (CR)

Geographic Range [top]

Range Description:Despite its scientific name, the Sicilian Fir (Abies nebrodensis) does not grow in the Nebrodi Mountains, but is presently limited to the steep, dry slopes between Vallone Madonna degli Angeli, Monte Staircase, Monte dei Pini and Rosskopf, in the territory of the Municipality of Polizzi Generosa in the Madonie Mountains in the north-central part of Sicily.

Population [top]

Population:The Madonie Mountains, rising to 1,979 m, were once covered by A. nebrodensis. By 1900, the species was considered extinct, due to extensive logging and erosion, but was rediscovered in 1957. The current population consists of 24 mature trees (Thomas 2013).
Current Population Trend:Stable
Additional data:
Number of mature individuals:30Continuing decline of mature individuals:No
Extreme fluctuations:NoPopulation severely fragmented:No
No. of subpopulations:1Continuing decline in subpopulations:No
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:Yes

Habitat and Ecology [top]

Habitat and Ecology:The species grows at around 1,500 m altitude on limestone soil.
Continuing decline in area, extent and/or quality of habitat:No

Use and Trade [top]

Use and Trade: The tree is not currently utilised, but was subject in the past to logging.

Threats [top]

Major Threat(s): The principal threat facing this species is the small population size. It will continue to be dependent on on-going conservation measures, especially fire suppression and habitat improvement.

Conservation Actions [top]

Conservation Actions: 1). This species is included in Appendix I of the Bern Convention and as a priority species in Annexes II and IV of the Habitats Directive. The woodland vegetation in which this species is found is listed in Annex I of the same Directive.

2). In situ: An EU LIFE funded project was carried out from 2001-2005. The immediate aim of the project was to stabilize the existing population and improve the survival rate of natural seedlings and planted trees raised as part of an ex-situ programme. Wider aims included the elimination of non-indigenous fir species and the restoration of the natural ecosystem. All work has been carried out within the boundaries of the Madonie Regional Park. The number of trees has increased from 24 to 30, while natural seedlings have increased from 30 to 80. These are still immature.

3). Ex situ: An extensive ex-situ programme has been in place for a number of years with trees planted in the Botanical Garden of Palermo (Italy) as well as in summer villas and second homes in the Madonie Mountains, slightly apart from their natural area of distribution.  They have also been distributed to other botanic gardens and arboreta in Europe. A programme of controlled pollination instigated as part of the EU LIFE funded project has resulted in the production of an additional 3,000 plants for reinforcing the existing population.
