    Evaluating the feasibility of pangolin farming and its potential conservation impact

    Pangolins are threatened by overexploitation for local and international use. They are subject to an international commercial trade ban, and are also the focus of other interventions, including attempts at commercial captive breeding. The impact that the latter could have on the conservation of wild populations deserves consideration. We critically evaluate the feasibility of commercial captive breeding (or farming) of pangolins to displace wild collection and assess its potential conservation impact on pangolin conservation using a recently published framework developed for this purpose. Of the 17 conditions posited that need to be met for supply-side interventions to displace wild collection, we find that pangolins meet a maximum of only six conditions. This analysis suggests that pangolin farming will not displace wild collection in the near future. Major barriers include an inability to breed pangolins on a commercial scale and available data suggest that it would be unprofitable. The immediate impact of pangolin farming on conservation of the species’ is unclear, but it is unlikely to benefit the conservation of wild populations. If commercial captive breeding were possible, it is uncertain how it would affect economic incentives for poaching, interactions between legal and illegal markets, stockpile policies, and how consumers and Traditional Chinese Medicine (TCM) practitioners would respond. To understand better the potential overall impact of pangolin farming on wild populations there is a need for further research on these uncertainties. The framework used has utility in analysing the potential impact of wildlife farming but there remains a need for a more robust approach to evaluate potential impacts of supplyside interventions.http://www.elsevier.com/locate/geccohb2020Mammal Research InstituteZoology and Entomolog

    Haematology and biochemistry values for Temminck’s pangolins (Smutsia temminckii) from Zimbabwe

    Blood biochemistry values are routinely employed during clinical examinations to assess the health of the patient and to identify potential underlying conditions. No blood biochemistry data are currently available for Temminck’s pangolin (Smutsia temminckii), a species that is being confiscated from both the domestic and international trade with increasing frequency, and this lack of data is hampering rehabilitation efforts. We determined haematological and serum biochemical values for ten Temminck’s pangolins rescued from the illegal wildlife trade in Zimbabwe and placed in the care of the Tikki Hywood Foundation as part of their rehabilitation. Our results suggest a large overlap in serum biochemistry and haematology values with previously reported values for other pangolin species, but also suggest some apparent differences. Haemoglobin, mean corpuscular haemoglobin and albumin:globulin ratio were positively correlated with mass, while alkaline phosphatase and amylase were negatively correlated with mass. Lymphocytes and monocytes were positively correlated with body condition, while mean corpuscular volume, alanine aminotransferase and total bilirubin were negatively correlated with condition. These results suggest that at least some parameters are independent of mass and are directly correlated with body condition and may therefore be informative in rapid health assessments of confiscated individuals.https://www.tandfonline.com/loi/tafz202021-04-16hj2020Mammal Research InstituteZoology and Entomolog

    Evaluating methods for detecting and monitoring pangolin (Pholidata: Manidae) populations

    The behaviours, ecologies and morphologies of pangolins make them challenging to survey and monitor, and non-targeted wildlife surveys have not produced robust status assessments, especially where population densities are low because of overexploitation. To inform the development of feasible survey and monitoring techniques for pangolins, we conducted a systematic review of all traceable efforts used to survey and monitor pangolins to date: 87 articles were included in the review. Pitfalls of current approaches are discussed and recommendations made on suitable methods. Recommendations include the use of mark-recapture for burrow-dwelling species, community interviews, sign-based surveys in arid and open habitats, detection dog teams, and targeted camera-trapping. Occupancy sampling using camera-traps could be used to monitor some pangolin populations, particularly ground-dwelling species, but the rarity of all species makes it uncertain whether this would provide enough data for monitoring; combinations of methods used within an occupancy sampling framework are likely to be the most effective. There will be many circumstances where direct monitoring of a population at a site, to a level that will generate precise data, is not financially viable nor the best use of conservation resources. In many sites, particularly in Asia, pangolins are too rare as a result of overexploitation, and/or occur in inaccessible areas where significant resources will be needed to implement a targeted monitoring programme. Under such circumstances, the use of proxy variables, including status of other hunting-sensitive species that are easier to record, in combination with enforcement or patrol data and/or community interviews, is likely to be the most cost-effective method for assessing the impact of conservation interventions on pangolin status. The publication of incidental observations and survey ‘by-catch’ would significantly improve understanding of pangolin status and ecology, and therefore how best to identify, conserve and monitor priority populations
