| Summary: | The Proboscis Monkey is endemic to Borneo, where the species is widely
distributed in mangroves and estuarine habitat. Sensitive to disturbance, and with a
declining population listed by IUCN as ‘Endangered’, protective legislation is generally in
place. Treated as an ‘iconic’ species for tourism in Sarawak, several mangrove areas have
been protected for conservation of the species. Limbang Mangrove National Park is one
such place but, with an estimated population of 44 individuals in 2019, had become a
critical site. A new survey of 11 boat trips covering 223.59 km of mangrove riverbank in
Limbang Mangrove National Park and adjoining estuaries recorded 236 individuals in 34
groups. The estimated population density was 1.03-1.78 individuals/km2, and 0.15-0.25
groups/km2. Proboscis Monkeys were evenly distributed within the National Park
boundaries, but concentrated at the centre of the Park. A questionnaire survey of local
communities found that more than 50% of respondents supported conservation of this
species. Based on the Boosted Regression Tree analysis, locality and income of the
respondents were the most influential factors that influenced their perception towards the
conservation of Proboscis Monkey in Limbang Mangrove National Park. We conclude that
conservation and sustainable ecotourism activities regarding Proboscis Monkeys in
Limbang Mangrove National Park should give priority to carfeful planning, taking into
consideration the long-term existence of this totally protected species. |
