Assessment Information [top]

Red List Category & Criteria: Endangered B2ab(iii,v) ver 3.1
Year Published: 2011
Date Assessed: 2011-02-15
Assessor(s): Marrero Rodríguez, Á
Reviewer(s): Peraza Zurita, M.D. & Bilz, M.
Justification:
Teline rosmarinifolia is classed Endangered for its area of occupancy is 21.25 km2, it is distributed throughout a low number of locations and several factors appear as threats to its conservation. A fire some years ago exerted a high negative impact on the taxon and no recovery has been observed. It is affected by predation and tends to appear sheltered in areas out of reach of herbivorous species, restricted within its potential distribution range. Negative population trends have been observed for the majority of its population.

Geographic Range [top]

Range Description:This taxon is endemic to the island of Gran Canaria, Canary Islands, Spain (Dirección General de Medio Natural y Política Forestal del MARM 2007). Two subspecies have been described: Teline rosmarinifolia ssp. eurifolia and Teline rosmarinifolia ssp. rosmarinifolia.

Teline rosmarinifolia ssp. eurifolia appears restricted to the massif of Tamadaba, in the northwestern part of the island, where five subpopulations have been found. Its area of occupancy has been estimated in between 4 and 5.5 km2 (4 grid cells of 1x1 km or 22 grid cells of 500x500 m) (Gobierno de Canarias 2004), stable since the discovery of the species.

Teline rosmarinifolia ssp. rosmarinifolia has been reported to present 21 subpopopulations (Beltrán Tejera et al. 1999, Gobierno de Canarias 2009). Its area of occupancy has been estimated in between 13.50 and 15.75 km2 (54 and 63 grid cells of 500x500 m). Its distribution was reduced by a fire in 2007.

Population [top]

Population:A total population size between 32,012 individuals (Commission of the European Communities 2009) and 42,990 individuals (Gobierno de Canarias 2004, 2009) has been reported. The subspecies eurifolia has less than 700 individuals.
The presence of reproductive individuals has been reported to be low for Teline rosmarinifolia ssp. eurifolia (Dirección General de Medio Natural y Política Forestal del MARM 2007).
Six subpopulations of Teline rosmarinifolia ssp. rosmarinifolia were affected by a fire in 2007. This led to a decrease of the population size and distribution area of this taxon. No recovering has been detected and the current population trend is thought to be regressive.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:42990
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Teline rosmarinifolia ssp. eurifolia grows in sub-humid rupicolous communities on crags, within the potential distribution range of mixed pine forests Pinetum canariensis subas. ericetosum arboreae and occasionally Telino canariensis-Adenocarpion foliolosi.
Teline rosmarinifolia ssp. rosmarinifolia grows towards the leeward, in xerophytic scrublands, within the distribution range of thermophile communities and transition communities towards pine forest, such as Mayteno-Juniperion canariensis, Cisto-Pinion canariensis and Soncho-Aonion. Under pressure it appears sheltered in rupicolous communities.
Systems:Terrestrial

Use and Trade [top]

Use and Trade: No traditional use or trade is known for this species.

Threats [top]

Major Threat(s): The main threat affecting Teline rosmarinifolia is predation by goats and rabbits, which limits the presence of reproductive individuals and affects the quality of the habitat of this taxon, forcing it to shelter in inaccessible areas (Gobierno de Canarias 2004, 2009). Competition with the exotic invasive Pennisetum setaceum has been reported as a threat to Teline rosmarinifolia ssp. eurifolia.

Conservation Actions [top]

Conservation Actions: This species is listed as priority species on Annex II of the Habitat Directive and under Appendix I of the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention).

Teline rosmarinifolia ssp. eurifolia is classed CR B1ab(iii)+2ab(iii) in the Spanish Red List (Moreno 2008). It is included as species "En peligro de extinción" in the national catalogue of threatened species of Spain, and as species "de interés para los ecosistemas canarios" in the regional catalogue. It occurs in the protected area Parque Natural de Tamadaba. Seeds are stored in the germplasm bank Jardín Botánico Viera y Clavijo.

Teline rosmarinifolia ssp. rosmarinifolia is classed EN B2ab(iii,v) in the Spanish Red List 2008. It is included as species "de interés para los ecosistemas canarios" in the catalogue of protected species for the Canary Islands.

Proposed actions in order to ensure the conservation of this taxon include seeds collection and storage, ex situ cultivation, herbivorous species control or eradication, and the implementation of population reinforcement measures.
