Justification of Red List Category
This species is scarce and local within its restricted range, and is likely to have a small global population size. It is suspected to be declining moderately rapidly owing to ongoing habitat loss. It is currently considered Near Threatened, and further studies are urgently required in order to clarify the magnitude of threats facing it.
The population size of this species has not been quantified, but it is described as uncommon and local.
This species appears to have become increasingly scarce in recent years, and moderate declines are likely to be occurring as a result of habitat loss and degradation.
Heleia muelleri is restricted to Timor, Indonesia and Timor-Leste, where it is generally uncommon and local, although it can be moderately common in ideal habitat.
This species occurs up to 1,300 m in monsoon forest. It appears to favour lower-lying areas with closed-canopy forest, and may not persist in secondary habitats.
The closed-canopy forests inhabited by this species are constantly diminishing in extent as a result of logging, clearance for agriculture and mining activities.
Conservation Actions Underway
Conservation Actions Proposed
Conduct repeated surveys within the range to determine current distribution and abundance, as well as assess population trends and rates of habitat loss. Conduct ecological studies to improve understanding of its precise habitat requirements, particularly tolerance of secondary habitats and response to fragmentation. Designate areas of suitable habitat as protected areas.
