Assessment Information [top]

Red List Category & Criteria: Endangered B2ab(ii,iii,iv,v) ver 3.1
Year Published: 2013
Date Assessed: 2011-06-02
Assessor(s): Farjon, A.
Reviewer(s): Thomas, P. & Adams, R

The assessment of the species as a whole is driven by the status of the most common, nominate variety (var. gracilior); the addition of locations from inclusion of the other two varieties (var. ekmanii and var. urbaniana) still keeps the number of locations under five. The species is Endangered under criterion B2.

Population [top]

Population:This species consists of three varieties, two of which are extremely localized. The nominate variety is more abundant, but still occupies a limited area. The total number of mature individuals is not known but is probably below 1,000.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:999Continuing decline of mature individuals:Yes
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The three varieties each occur in very limited localities in the humid montane forest zone from 1,000 m to 2,550 m a.s.l.; their habitat is characterized by a scattering of Manacla palms and abundant epiphytes. The forest cover has been destroyed in most localities and secondary vegetation predominates, often dominated by the fern Pteridium aquilinum. In most localities the junipers are present with only solitary individuals. The species is mainly found on acid forest soil, but J. gracilior var. urbaniana occupies two limited areas, one near the summit of Pic la Selle between 2,300-2,550 m a.s.l. and the other on a plain in the Sierra de Baoruco surrounded by forest, both on limestone.
Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):30

Use and Trade [top]

Use and Trade: The wood is used for furniture and carving, and for firewood. In Haiti, where it does not occur in the wild, this variety is planted as an ornamental tree. No uses are known of the decumbent shrub J. gracilior var. urbaniana.

Threats [top]

Major Threat(s): Besides cutting for timber and firewood, this species is also threatened by forest clearing for pasture and by (man-made) fires.

Conservation Actions [top]

Conservation Actions: At least one variety (var. urbaniana) occurs mostly within a national park. Stricter regulation of cutting wood and grazing animals is urgently needed to protect this species and its varieties.
