Ixora pudica is endemic to Mahé, Silhouette and Praslin, Seychelles. The extent of occurrence (EOO) and area of occupancy (AOO) are estimated to be below 5,000 and 500 km² respectively, but the population is thought to be stable. It is mainly threatened through its restricted distribution. Invasive alien species could be a possible threat to the species but it seems to regenerate successfully. It is therefore unlikely that the species changes its threat status in near future. It is listed as Near Threatened.
Previously published Red List assessments:
1998 Vulnerable (VU)

Geographic Range [top]

Range Description: This species is endemic to the Seychelles. It occurs on Mahé and Silhouette (Robertson 1989, Friedmann 1994). The species is also known from Praslin but not mentioned in publications (V. Laboudallon pers. comm.). The total area of the three islands is 216 km² (National Statistics Bureau 2005). The AOO and EOO are estimated to be less than 500 and 5,000 km² respectively.

Population [top]

Population: The total population size is unknown, but estimated to be more than 10,000 mature individuals. The population is thought to be stable. On Praslin, the species is apparently rare as it is not mentioned in any literature source (V. Laboudallon pers. comm.).
Current Population Trend: Stable
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: Shrub or small tree up to 7 m tall, glabrous in all its parts. Occurring in humid forest at intermediate and high altitudes on well drained ground mainly 400-850 m (Carlström 1996). It is unclear if the species is dispersed by frugivores (Kronauer 2005) but the fruit seems suitable for bird dispersal.
Systems: Terrestrial

Threats [top]

Major Threat(s): This species is regenerating successfully, but could be affected by the invasion of alien species causing a decline in the quality of its habitat.

Conservation Actions [top]

Conservation Actions: The species is found in the Morne Seychellois National Park.
