Thesis title: Conservation strategies for Delacour’s Langur (Trachypithecus delacouri) in Vietnam: Behavioural comparisons and reviewing a release

Supervisor: Prof. Colin Groves

My research interests lie in the areas of animal behaviour, conservation and ecology, with a focus on primates. My honours thesis, at the University of Canterbury, focused on tantalus monkeys (Chlorocebus tantalus tantalus) in Nigeria and their contribution to seed dispersal and forest restoration in a montane forest.

My PhD is focusing on the critically endangered primate species, Delacour's langur (Trachypithecus delacouri), which occurs in a small region of northern Vietnam. This thesis aims to further the conservation of T. delacouri by reviewing a trial release of captive individuals as a potential conservation tool for the species, along with acquiring a greater understanding of the species’ behaviour.  My fieldwork, in part, involved collecting behavioural data from a small captive population at the Endangered Primate Rescue Center at Cúc Phương National Park, focusing on daily activity budgets, vocalisations, dominance and infant behaviour. I also conducted fieldwork in Vân Long Nature Reserve collecting behavioural data from wild individuals to provide a comparison.  In addition, my research involves reviewing a release conducted by the EPRC of three captive T. delacouri into Vân Long, and the subsequent monitoring of these individuals via GPS radio collars.  I plan to contextualise this by considering past releases in both a primatological and Vietnamese context, and make recommendations for future conservation strategies for Delacour’s langur.
