Scientific Name: Eugenia ericoides Guillaumin

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2010
Date Assessed: 2007-05-15
Assessor(s): Hequet, V.
Reviewer(s): Pollock, C.M. & Hilton-Taylor, C.
Justification:
Eugenia ericoides has an extent of occurrence (EOO) of 6,970 km² and an area of occupancy (AOO) of 60 km². The species is endemic to New Caledonia, where it is known from 15 fragmented locations. Of the two habitats it occupies, dry forests have been reduced dramatically in New Caledonia, both in size and in quality. They have been intensively cut for agricultural purposes over the last century and what remains today are highly fragmented patches that suffer intense predation by the introduced Rusa Deer (Cervus timorensis russa), and uncontrolled fires. The reduction of this habitat has been estimated at 95% over the last 150 years (Bouchet 1995) and degradation continues today. In maquis, E. ericoides is threatened by mining activities. The species is assessed as Near Threatened because it almost meets the criteria thresholds for a threatened listing under criterion B.

Geographic Range [top]

Range Description:This species is endemic to New Caledonia. It is present nearly all along the west coast. From south to north, it is found in Mont Dore, Noumea and Paita, Poya, Koné and Voh, Koumac and Poum. Distance between subpopulations can be as high as 127 km. Its total extent of occurrence is 6,970 km², and its estimated area of occupancy within this range is 60 km².

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits tropical dry forests and maquis. 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. Maquis are also extremely vulnerable habitats because of the richness of their soil and their mining value.
Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Yes

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.
