Presentation 1: Sustainable market linkage for Cardamom product in Quan Ba district, Ha Giang province, Vietnam - a potential livelihood modeling towards WBCG conservation in MCC SHCA (Yen Bai province, Vietnam) by Duong Van Khai - Livelihood Advisor, FFI - Vietnam Programme
Question: How applicable is the livelihood model in MCC-ML context? What adjustments can we make to use it in a different area?

Modifications to adapt to specific site conditions

Made in consultation from local officers

Question: Effect of canopy cover of cardamon field in Tung Vai

Research was conducted a few years ago and a follow-up study is in the design stage.

In 2008: A PVA was conducted for the Tonkin snub-nosed monkeys in Quan Ba, Ha Giang with consideration for their movement requirements (maximum leaping distance = 6 meters), using GIS, and remote sensing data -> areas suitable for the movement of the species were still identified (Trinh Dinh Hoang)

Presentation 2: Current white-cheeked gibbon research in the Annamite Mountains of Laos: Survey methods and distribution range by Camille Coudrat - Association Anoulak, Laos
Question: Canopy camera trap study by Association Anoulak

Design: Experimental with 7 camera traps set up on fruiting trees (e.g. fig, and others with high chance of capturing target species) at approx. 30 meters high, systematic grid survey

Access: canopy rope - intensive training by professional tree climber, with harness, rope, set of equipment

-> much more time-consuming and requires trained climbers

Identifying the gibbons from canopy pictures was hard, as most individuals photographed were similar-looking to N. siki or N. leucogenus

Illegal hunting and trade of primates at the study site: not many cases of capture though there are cases of adult gibbons hunted for food and infants confiscated

Presentation 1: Long-term monitoring of gibbons in difficult terrain by Dr. Oliver Wearn - Technical Advisor, FFI
Question: AudioMoth noise issue

Rainy, windy conditions can result in noises in the recordings

Options for enclosure to reduce the noise: hard case from AudioMoth manufacture (used by FFI Vietnam), ziploc bag, rain pipe

Settings: new version of configuration app retains settings

Question: In Pu Mat, how do we detect the Northern white-cheeked gibbons's population change with occupancy models?

Gibbon density estimate: 0.48 group/km2, still low compared to estimates in other sites globally

End-mixture modelling can be used to account for changes in population size

Canid Howl project: multilateration method, which requires large amount of data, uses time delay to triangulate the animals' location (Angela Dassow)

Question: Application and limitations of study results on genetic diversity?

Sample collection: attempted with limited success at the moment

Presentation 2: A review of survey methods used for surveying the WBCG in MCC-ML, Vietnam and options for future surveys by Trinh Dinh Hoang - Freelance researcher in wildlife conservation
Question: Challenges in using UAV with thermal cameras: distribution has to be known beforehand, noise disturbance

Used in combination with traditional auditory method -> identify gibbon group's general locations

UAV with RGB and thermal cameras then used to confirm the group count and structure

Presentation 3: Major threats to the N. concolor and the potential for using species distribution modeling in assessing suitable habitat for the N. concolor conservation by Tran Van Dung - Researcher
Question: How many variables should we add to the Species Distribution Models (SDMs)? How do we decide which are important?

Discussions: Experiences from AUV and thermal camera testing in limestone forests in Vietnam
Detectability

Hard to detect animals from far away, to distinguish among individuals and count in reality

High temperature of the rock surface makes it difficult to distinguish small animals like gibbons using Mavice2 in Bangliang NNR (Guangxi, China) (Li Xing Kang)

Noise disturbance

Maverick 2 noise did not affect the Tonkin Snub-nosed Monkeys in Ha Giang, but Phantom (larger) may (Le Khac Quyet)

Others

Flying permits need to be obtained in advance

Presentation 1: Vietnam WBCG conservation project overview: Interventions and key achievements by Mr. Hoang Van Lam - Country Programme Manager, FFI - Vietnam Programme
Question: FFI's future plans for species conservation in MCC-ML

Continue with species protection through patrols

More emphasis on species monitoring and research into the future

Scoping for potential translocation

Presentation 2: Experiences and lessons from long-term monitoring of Nomascus councilor at Dazhaizi, China by Dr. Xiaowei Niu - Kunming Institute of Zoology, CAS, China
Question: Progress of acoustic monitoring research at Dazhaizi

Analysis is still ongoing

Cloud Mountain Conservation applied acoustic monitoring for 10-day periods (Yan Lu)

Presentation 3: Population size and distribution of N. concolor in Mu Cang Chai Species and Habitat Conservation Area, Viet Nam by Tran Van Dung, Researcher
Question: Group determination, especially in the area between the two PAs

Determined from discussions with team

Question: Decrease in population size following the establishment of Muong La NR in Vietnam

Adverse weather conditions

Hunting risks (more intense in Muong La than in Mu Cang Chai)

Standardisation of field and analysis methods is much needed in future work (Trinh Dinh Hoang)

Discussions on gibbon calling frequency

Experience in Daizhixi (China): 1 out of 3 days for the raining season, almost every day for the dry season (Xiaowei Niu)

Survey in MCC-ML area (Vietnam) was conducted in June, with many rainy mornings (Tran Van Dung)

Experience from Laos with the Northern white-cheeked gibbons: gibbons don’t sing much during the rainy season (Camille Coudrat)

Cheyne et al. (2007) on Hylobates albibarbis, with discussions on environmental factors (LINK)
