Phayre’s Langur

Measurement

Head to body length

Head and body: Male 42- 60 cm; Female 44-57 cm Tail Length: Male 75-86 cm; Female 72-80 cm

Body weight (kg)

Body weight (kg): male 5.7-9.1; female 6.4-7.5

Justification

Severally isolated and highly hunting pressure due to eating gallstone for medicinal effects. It is inferred to have continuous decline in population.

Details

The generation length for T.phayrei is 11 years (https://datadryad.org/resource/doi:10.5061/dryad.gd0m3/1). Population trend is declined and limited information on total population in Myanmar. AOO of the species is 68 km2 and its EOO cover 533,330 km2 in its available habitats.

Habitat ecology

Primary and secondary high-elevation evergreen, semi-evergreen, and mixed moist deciduous forests throughout most of its range. It can also be found in tea plantations (Mittermeier et al., 2013). The species is adaptable to different habitats.

Distribution

Threats to survival

Forest destruction, habitat fragmentation, hunting for its gall stone as traditional medicines and bush meat.

Instruction: The visualization shows threats that are impacting each species. According to IUCN, direct threats are the proximate human activities or processes that have impacted, are impacting, or may impact the the status of the taxon being assessed. Click of the highlighted icons to see details each threat category.

Use and trade

Its gallstones are used in traditional medicine. Bush meat for protein.

Conservation Actions

Research

Research undertaken

T. phayrei was designated as completely protected animals according to the Conservation of Biodiversity and Protected Area Law (2018) and as Endangered species (IUCN, 2020). Molecular study and population abundance for Alaungdaw Kathapa National Park were conducted in 2010 (Thant et. al., 2013).

Research needed

Comanagement for species conservation is highly needed to implement. Molecular study, ecology, behavior study and current population status are needed. Threats assessment on the species survival is needed to conduct effective law enforcement along with public awareness.
