Scientific Name: Cupaniopsis globosa
Species Authority: Adèma

Assessment Information [top]

Red List Category & Criteria: Vulnerable A2ce ver 3.1
Year Published: 2010
Date Assessed: 2007-05-15
Assessor(s): Hequet, V.
Reviewer(s): Pollock, C.M. & Hilton-Taylor, C.
Justification:
Cupaniopsis globosa has an extent of occurrence (EOO) of 2,450 km² and an area of occupancy (AOO) of 68 km²; it is known from 14 locations. The species is threatened because it is endemic to New Caledonian dry forests and its habitat is among the most threatened in the country. Dry forests have been reduced dramatically, both in size and in quality. They have been severely cleared for agricultural purposes over the last century and what remains today are highly fragmented patches that suffer intense predation by introduced Rusa Deer (Cervus timorensis russa). The reduction of dry forest has been estimated at 95% over the last 150 years (Bouchet 1995) and this degradation continues today. From this it is suspected that a population reduction of at least 30% has occurred over this time period; the actual generation length for this species is not known, but with evidence for dramatic declines in dry forest habitat it is likely that there has been a population reduction of at least 30% over the last three generations.
History:
1998 Vulnerable (Oldfield et al. 1998)
1998 Vulnerable
1997 Vulnerable (Walter and Gillett 1998)

Geographic Range [top]

Range Description: This species is endemic to New Caledonia. It must once have been common all along west coast. It is now present from Paita to Pouembout, with gaps in the distribution as large as 102 km. Its total extent of occurrence is 2,450 km², and its estimated area of occupancy within this range is 68 km².

Habitat and Ecology [top]

Habitat and Ecology: This species is endemic to New Caledonian dry forests (including calcareous forests). Tropical dry forests are probably among the world’s most endangered of all lowland tropical forests. Because of their propensity to become pastures and their susceptibility to fire, dry forests have reduced dramatically, in size as well as in quality. In New Caledonia, they’ve been intensively cut for agricultural purposes for a century; what remains today are highly fragmented patches that have been estimated at 2% of the original area.
Systems: Terrestrial

Threats [top]

Major Threat(s): The major threat is lowland clearing for cattle grazing and agriculture, which began in the 1850s and is ongoing. Another threat comes from the Rusa Deer (Cervus timorensis russa), which was introduced in the 1880s and adapted extremely well to the Caledonian habitats. Its population may have reached 105,000–110,000 individuals in the wild. This deer consumes a wide variety of plant species and also causes severe damage to trees by rubbing antlers against tree stems. The third major threat is uncontrolled fires that sweep across lowlands of New Caledonia each year during the dry season and have slowly transformed remnant patches of dry forest into shrubland dominated by Acacia spirorbis and Leucaena leucocephala, or Niaouli (Melaleuca quinquenervia) savannas.
