This is the author accepted manuscript. The final version is available from Wiley via the DOI in this recordData accessibility: All data used in the analyses are freely available in the University of Oxford research archive at this link: https://ora.ox.ac.uk/objects/uuid:556a8a97-2d3d-4bf2-8fc1-359ce9786986. Data were gathered from 101 English language publications that empirically tested the UCT method. For each paper, information on 17 variables was collected, including the context (e.g. discipline, behaviour studied, rationale for using UCT, location), details of survey administration (e.g. whether a pilot study was conducted, whether design assumptions were checked), type of analysis, and comparisons to other methods (e.g. direct questions). Full data collection protocol and citations for all 101 reviewed publications are included in Appendix III and IV.1.Researchers and practitioners are increasingly using methods from the social sciences to address complex conservation challenges. This brings benefits but also the responsibility to understand the suitability and limitations of these methods in different contexts. After years of use in other disciplines, the Unmatched Count Technique (UCT) has recently been adopted by conservation scientists to investigate illegal and socially undesirable human behaviours. Here we provide guidance for practitioners and researchers on how to apply UCT effectively, and outline situations where it will be most and least appropriate. 2.We reviewed 101 publications in refereed journals that used UCT to draw conclusions on its use to date and provide recommendations on when and how to use the method effectively in conservation. In particular, we explored: type of studies undertaken (e.g. disciplines; behaviour being studied; rationale for using UCT); survey administration (e.g. sample size, pilot studies, administration mode); UCT outcomes (e.g. type of analyses, estimates, comparison with other methods); and type of recommendations. 3.We show that UCT has been used across multiple disciplines and contexts, with 10 studies that focus on conservation and natural resource use. The UCT has been used to investigate topics falling into five categories: socially undesirable behaviours, socially undesirable views, illegal or non‐compliant behaviours, socially desirable behaviours; and personal topics (e.g. being HIV positive). It has been used in 51 countries and is suitable to several situations, but limitations do exist, and the method does not always improve reporting of sensitive topics. 4.We provide best‐practice guidance to researchers and practitioners considering using UCT. We highlight that alternate methods should be considered if sample sizes are likely to be small, the behaviour in question is likely to be extremely rare, or if the behaviour is not particularly sensitive. UCT can be a useful tool for estimating the extent of non‐compliance within a conservation context, but as with all scientific investigation, careful study design, robust sampling and consistent implementation are required in order for it to be effective.Oxford Martin Programme on the Illegal Wildlife TradeNational Environment Research Council (NERC)Darwin Initiativ

Captive reptile mortality rates in the home and implications for the wildlife trade

The trade in wildlife and keeping of exotic pets is subject to varying levels of national and international regulation and is a topic often attracting controversy. Reptiles are popular exotic pets and comprise a substantial component of the live animal trade. High mortality of traded animals raises welfare concerns, and also has implications for conservation if collection from the wild is required to meet demand. Mortality of reptiles can occur at any stage of the trade chain from collector to consumer. However, there is limited information on mortality rates of reptiles across trade chains, particularly amongst final consumers in the home. We investigated mortality rates of reptiles amongst consumers using a specialised technique for asking sensitive questions, additive Randomised Response Technique (aRRT), as well as direct questioning (DQ). Overall, 3.6% of snakes, chelonians and lizards died within one year of acquisition. Boas and pythons had the lowest reported mortality rates of 1.9% and chameleons had the highest at 28.2%. More than 97% of snakes, 87% of lizards and 69% of chelonians acquired by respondents over five years were reported to be captive bred and results suggest that mortality rates may be lowest for captive bred individuals. Estimates of mortality from aRRT and DQ did not differ significantly which is in line with our findings that respondents did not find questions about reptile mortality to be sensitive. This research suggests that captive reptile mortality in the home is rather low, and identifies those taxa where further effort could be made to reduce mortality rate

Addressing human-tiger conflict using socio-ecological information on tolerance and risk

Tigers are critically endangered due to deforestation and persecution. Yet in places, Sumatran tigers (Panthera tigris sumatrae) continue to coexist with people, offering insights for managing wildlife elsewhere. Here, we couple spatial models of encounter risk with information on tolerance from 2,386 Sumatrans to reveal drivers of human-tiger conflict. Risk of encountering tigers was greater around populated villages that neighbored forest or rivers connecting tiger habitat; geographic profiles refined these predictions to three core areas. People’s tolerance for tigers was related to underlying attitudes, emotions, norms and spiritual beliefs. Combining this information into socio-ecological models yielded predictions of tolerance that were 32 times better than models based on social predictors alone. Pre-emptive intervention based on these socio-ecological predictions could have averted up to 51% of attacks on livestock and people, saving 15 tigers from the wild. Our work provides further evidence of the benefits of interdisciplinary research on conservation conflicts

Training Programmes Can Change Behaviour and Encourage the Cultivation of Over-Harvested Plant Species

Cultivation of wild-harvested plant species has been proposed as a way of reducing over-exploitation of wild populations but lack of technical knowledge is thought to be a barrier preventing people from cultivating a new species. Training programmes are therefore used to increase technical knowledge to encourage people to adopt cultivation. We assessed the impact of a training programme aiming to encourage cultivation of xaté (Chamaedorea ernesti-augusti), an over-harvested palm from Central America. Five years after the training programme ended, we surveyed untrained and trained individuals focusing on four potential predictors of behaviour: technical knowledge, attitudes (what individuals think about a behaviour), subjective norms (what individuals perceive others to think of a behaviour) and perceived behavioural control (self assessment of whether individuals can enact the behaviour successfully). Whilst accounting for socioeconomic variables, we investigate the influence of training upon these behavioural predictors and examine the factors that determine whether people adopt cultivation of a novel species. Those who had been trained had higher levels of technical knowledge about xaté cultivation and higher belief in their ability to cultivate it while training was not associated with differences in attitudes or subjective norms. Technical knowledge and perceived behavioural control (along with socio-economic variables such as forest ownership and age) were predictors of whether individuals cultivate xaté. We suggest that training programmes can have a long lasting effect on individuals and can change behaviour. However, in many situations other barriers to cultivation, such as access to seeds or appropriate markets, will need to be addressed

Foodborne disease poses a serious threat to public health. In the UK, half a million cases are linked to known pathogens and more than half of all outbreaks are associated with catering establishments. The UK Food Standards Agency (FSA) has initiated the UK Food Hygiene Rating Scheme in which commercial food establishments are inspected and scored with the results made public. In this study we investigate the prevalence of food risk increasing behaviours among chefs, catering students and the public. Given the incentive for respondents to misreport when asked about illegal or illicit behaviours we employed a Randomised Response Technique designed to elicit more accurate prevalence rates of such behaviours. We found 14% of the public not always hand-washing immediately after handling raw meat, poultry or fish; 32% of chefs and catering students had worked within 48 hours of suffering from diarrhoea or vomiting. 22% of the public admitted having served meat “on the turn” and 33% of chefs and catering students admitted working in kitchens where such meat was served; 12% of the public and 16% of chefs and catering students admitted having served chicken at a barbeque when not totally sure it was fully cooked. Chefs in fine-dining establishment were less likely to wash their hands after handling meat and fish and those who worked in award winning restaurants were more likely to have returned to work within 48 hours of suffering from diarrhoea and vomiting. We found no correlation between the price of a meal in an establishment, nor its Food Hygiene Rating Score, and the likelihood of any of the food malpractices occurring

Using consumer preferences to characterize the trade of wild‐collected ornamental orchids in China

Over-exploitation of wildlife for trade threatens taxa globally. Interest in demand-side approaches to address this problem has grown but understanding of how consumer preferences shape demand remains limited. To quantify the role of consumer preferences for wild orchids in China’s horticultural market, we used conjoint analysis to determine which attributes are preferred by orchid owners and non-owners in two socio-economically contrasting areas of South China. Across all respondents, price was the most important attribute followed by flower colour. Whilst Xishuangbanna participants exhibited a slight preference for wild over cultivated plants, origin (wild/cultivated) was of minimal importance. We also measured awareness of orchid import regulations. Most did not recognise the CITES logo, and knowledge of import laws was significantly lower in Hong Kong than in Xishuangbanna. Our findings suggest that trade in wild ornamental orchids in South China is supply-driven, and strengthened regulations might be effective in reducing over-exploitation

Asking sensitive questions using the unmatched count technique: Applications and guidelines for conservation

Innovative techniques for estimating illegal activities in a human-wildlife-management conflict

Effective management of biological resources is contingent upon stakeholder compliance with rules. With respect to disease management, partial compliance can undermine attempts to control diseases within human and wildlife populations. Estimating non-compliance is notoriously problematic as rule-breakers may be disinclined to admit to transgressions. However, reliable estimates of rule-breaking are critical to policy design. The European badger (Meles meles) is considered an important vector in the transmission and maintenance of bovine tuberculosis (bTB) in cattle herds. Land managers in high bTB prevalence areas of the UK can cull badgers under license. However, badgers are also known to be killed illegally. The extent of illegal badger killing is currently unknown. Herein we report on the application of three innovative techniques (Randomized Response Technique (RRT); projective questioning (PQ); brief implicit association test (BIAT)) for investigating illegal badger killing by livestock farmers across Wales. RRT estimated that 10.4% of farmers killed badgers in the 12 months preceding the study. Projective questioning responses and implicit associations relate to farmers' badger killing behavior reported via RRT. Studies evaluating the efficacy of mammal vector culling and vaccination programs should incorporate estimates of non-compliance. Mitigating the conflict concerning badgers as a vector of bTB requires cross-disciplinary scientific research, departure from deep-rooted positions, and the political will to implement evidence-based management
