Reviewer(s): Silva, L., Scholz, S., del Arco Aguilar, M., Reyes Betancort, J.A. & Allen, D.J.
Justification:
This species is a small tree found only in the Canary Islands and Madeira. It is here assessed as Least Concern as it has a large extent of occurrence and there are no reported significant threats to this species. The species is found in an ex situ collections and extensively in protected areas.

Population [top]

Population:On Madeira, the population is between 1,000 and 5,000 and is stable. On the Canaries the population is very large and assumed to be stable.
Current Population Trend:Stable
Additional data:
Continuing decline of mature individuals:No
Extreme fluctuations:NoPopulation severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species grows as an evergreen small tree up to 10-15 m tall. The species is found mainly at middle altitudes in Mediterranean laurisilva and in substitutional Erica-Myrica thickets.
Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:No

Use and Trade [top]

Use and Trade: The tree is sold for use in horticulture. In Madeira, it is used for Christmas decoration. It was used for inlay and furniture.

Threats [top]

Major Threat(s): The seeds of this species are predated on by introduced rats post-dispersal, but it is not known what the effect of this is on the recruitment of the species (Salvande et al. 2006). The threats to this species in Madeira are invasive species, increasing the risk and intensity of fire (mainly Pittosporum and Acacia). The plant benefited from the abandonment of agriculture and has expanded into this area, however agriculture may return in the future.

Conservation Actions [top]

Conservation Actions: The Madeiran populations are found within the UNESCO World Heritage Site and in Natura 2000 sites. It was assessed as 'Lower Risk/near threatened' globally (WCMC 1998). Management of invasive populations would be beneficial for this species on Madeira. On the Canaries, most of the distribution is within natural protected areas. This species is reported as held in 15 ex situ collections (BGCI 2016).
