Banded Leaf Monkey Research

To do population monitoring and feeding analysis of banded leaf monkeys in Singapore


The banded leaf monkey (Presbytis femoralis femoralis) occurs on the southern Malay Peninsula and is critically endangered in Singapore. Recent taxonomic and genetic analyses suggest that the southern Malay Peninsula sub-species is likely to be a distinct species, highlighting the importance of conserving the populations. In order to help with conserving this Singapore native, we propose to test hypotheses regarding population size, reproductive biology and feeding behaviour. Continuous monitoring on banded leaf monkeys will be important in detecting changes in population and group demographics. Current data indicate that banded leaf monkeys may have at least one breeding cycle (birth in July) and the project aims to confirm this finding by monitoring one additional year.


Besides identifying food plant species through feeding observations, existing data will be complemented by extracting plant DNA sequences from faeces. These sequences can then be identified by comparing them with the DNA from plant specimens collected during vegetation sampling of the habitat. With accurate data on the feeding behaviour, behavioural ecology and reproductive biology of banded leaf monkeys, the project proposes to carry out a population viability assessment that will be important for examining the long-term prospects of the species in Singapore. These data will contribute to the conservation of banded leaf monkeys in Singapore.


WAZA Conservation Project 11010 is implemented by Andie Ang Hui Fang from the National University of Singapore, with support provided by Wildlife Reserves Singapore and involvement of National Parks Board Singapore.
