The LTM project collaborates with and supports several projects in South and South East Asia. See our current and upcoming activities below.


Statement, 17th November 2022:

Exploitation levels, and here especially the trade for laboratory research, threaten the survival of the long-tailed macaque. During the pandemic, the demand for long-tailed macaques in laboratory research increased, which sparked habitat-countries to increase exports of the species.

Yesterday (16 NOV 2022) the USFWS released news of the indictment of several government officials from Cambodia and leaders of a research and breeding group from Hong Kong regarding the illegal laundering of wild-caught long-tailed macaques as captive bred

We are extremely happy to see indictments happen and we believe this is very positive news for the long-tailed macaque. However, we believe to truly conserve the species, we need to focus on reducing the demand. This means targetting the people/institutions that order the macaques and ensure they take responsibility for their actions, and reduce their reliance on non-human primate research subjects.

The long-tailed macaque faces many threats and it will take a global effort to ensure its survival in its native habitats, where it provides a crucial ecological and cultural service to wildlife, nature and people.

Updated 21st July 2022

The long-tailed macaque and all subspecies have been reassesed/assessed for the IUCN Red List. The long-tailed macaque is now Endangered A3cd:

Please read our statement below to understand the assessment that was a collaboration within the LTM Project:

June 2022

General: Our main focus currently, is gathering data on the distribution of long-tailed macaques in SE Aisa. We are trying to get information from all sources possible, including cameratrap footage, anectdotal information and researchers in the field. We have made data sharing with several organisations in Cambodia, in collaboration with Seiha Hun, Conservation International. We believe that knowledge on the current status of the long-tailed macaques is the best way for us to help this species.

The fantastic photographer Neil Challis is working with our administrator, Nadja Ramseyer, on a short film about the The Long-Tailed Macaque project. Take a look at this amazing video Neil made, about the relationsship between long-tailed macaques and a local community in a mangrove forest on the Andaman coast of Southern Thailand.

We are planning a perception survey, to get a better understanding of the relationship between humans and macaques.


The board met on the 19th April to discuss our current focus and evaluate. It was a fruitful meeting and we are keeping our course and focusing on collecting all the information we need to effectively collaborate on conserving the long-tailed macaque. The board meets every 3rd month.

We held a successful workshop on the 25th February with 65+ attendees. Here habitat-country researchers provided updates on their research and the curent status of research on the long-tailed macaque in their country. We also discussed the activities going forward, which include a survey on the cultural behaviours of macaques by the MACS team, an internal survey of practical non-invasive coexistence techniques, and a list of which population census methods to employ where.

Mr. Bang Van Tran from the Southern Institute of Ecology in Vietnam has begun his large survey of the long-tailed macaque in Vietnam, documenting the population size and distribution through collecting existing data from local organisations and governments and by visiting sites to collect data himself. He will also be investigating the perceptions of local stakeholders towards the long-tailed macaque. All to better protect and manage the species.

Indonesia and Malaysia
We succesfully gained funding from QATO – a Danish animal welfare funding agency – for two projects; one in Indonesia with Kurnia Ilham, Andalas University on mitigating crop foraging by long-tailed macaques, and one in Malaysia with Animal Neighbours Project on mitigating negative human-macaque interactions in urban areas. Both projects focus on fostering coexistence by collaborating with local people.

Over the past six months, Tanvir Ahmed and his team from NACOM has conducted a a population census survey of the long-tailed macaque in Bangladesh. Sadly no individuals where found, and the species is now considered extinct in the country. Tanvir and his team are working on publishing the results.

At the Animal Neighbours Project, Malaysia, Ashwiini Paranjhoti, is working on improving the relationship between humans and monkeys in shared urban spaces.

Lao PDR:
Dr. Phaivanh Phiapalath is doing fieldwork, trying to locate the last long-tailed macaques of the country. It seems he has already discovered some, which we are very happy about.

The Philippines:
Emerson Sy, TRAFFIC Southeast Asia is leading a one-year trade survey.

Conservation International Cambodia hired a consultant who will be in charge of producing a current distribution map of long-tailed macaques in Cambodia, as well as an estimation of the population size derived from both existing material as well as census surveys conducted by the consultant.

We recently contributed to the IUCN Red List conservation status assessment of the species (Macaca fascicularis) and the nine sub species (M. f. condorensis, M. f. lasiae, M. f. fusca, M. f. umbrosa, M. f. tua, M. f. karimondjawae, M. f. fascicularis, M. f. aurea, M. f. atriceps). We are currently awaiting approval from IUCN.

Volunteers: Our volunteers are working very hard and we could not function without them. They are making distribution maps, content for our social media and giving talks and writing news pieces for the project.

Please get in touch if you have ideas for and/or want to get involved!
