The UK government is considering legislation to prohibit the importation of hunting trophies. We examine documented social, ecological, and political outcomes of two previous such bans. We find that the UK government's proposal shares the shortcomings of existing bans that have (1) failed to address, or have even amplified, key threats to hunted species, (2) imposed costs on citizens of other countries, and (3) delegitimized the Convention on International Trade in Endangered Species (CITES). Trophy import bans are blunt policy instruments that can cause more problems than they solve.

Reconciling conflicts between wildlife conservation and other human activities is a pervasive, multifaceted issue. Large carnivores, such as the African lion Panthera leo are often the focus of such conflicts as they have significant ecological and cultural value but impose severe social and financial costs on the communities that live alongside them.
To effectively manage human–lion conflict, it is vital to understand stakeholder decision-making and preferences regarding mitigation techniques and coexistence strategies.
We used a novel experimental game framed around lions and livestock protection, played across eight villages in Tanzania, to examine stakeholder behaviour in response to three incentive structures: support for non-lethal scaring, and individual- and community-level subsidies for provision of wildlife habitat.
We found that non-lethal deterrent methods were the preferred mitigation strategy and that individual subsidies most increased the provision of wildlife habitat. Subsidies that were conditional on other community members' decisions were less effective at increasing habitat choices. Player characteristics and attitudes appeared to have little influence on game behaviour. However, there was some evidence that gender, wealth, perceptions of respect, and the behaviour of other players affected decision-making.
Achieving success in managing conservation conflicts requires genuine stakeholder participation leading to mutually beneficial results. Our findings suggest that, while incentive-based instruments can promote pro-conservation behaviour, these may be more effective when targeted at individuals rather than groups. We demonstrate how experimental games offer a practical and engaging approach that can be used to explore preferences and encourage discussion of conflict management.

Conservation Biology, e13943
Large carnivores increasingly inhabit human-affected landscapes, which exhibit heterogeneity in biotic resources, anthropogenic pressures, and management strategies. Understanding large carnivore habitat use in these systems is critical for their conservation, as is the evaluation of competing management approaches and the impacts of significant
land-use changes. We used occupancy modeling to investigate habitat use of an intact eastern African large carnivore guild across the 45,000 km2 Ruaha-Rungwa landscape in south-central Tanzania. We determined the relative impact on five large carnivore species of biotic, anthropogenic, and management factors at the scales of home range selection
and short-term use within home ranges. We also specifically tested the effect of abandonment of trophy hunting areas on large carnivore occurrence. Patterns of habitat use differed among species. Lions (Panthera leo) appeared affected by top-down limitation, as their occurrence was significantly negatively associated with illegal human activity (β = –0.63 [SE
0.28]). African wild dogs (Lycaon pictus), instead, were limited by biotic features; the species was negatively associated with riverine areas of high sympatric predator density (β = –1.00 [SE 0.43]) and used less-productive habitats. Spotted hyaena (Crocuta crocuta) and leopard (Panthera pardus) persisted in more disturbed areas and across habitat types. Large carnivore occurrence was not affected by whether an area was used for photographic or trophy hunting tourism; regular law enforcement was instead a better predictor of occurrence. All species fared better in actively managed hunting areas than those that had been abandoned by operators. Overall, our findings highlight the divergent habitat requirements within large carnivore guilds and the importance of adopting an integrated approach to large carnivore
conservation planning in modern systems. We also identified a novel threat to African conservation areas in the form of decreased management investments associated with the abandonment of trophy hunting areas
Exploring the connections between giraffe skin disease and lion predation

Journal of Zoology, Volume 316, P49-60
Rates at which predators encounter, hunt and kill prey are influenced by, among other things, the intrinsic condition of prey. Diseases can considerably compromise body condition, potentially weakening ability of afflicted prey to avoid predation. Understanding predator–prey dynamics is particularly important when both species are threatened, as is the case with lions (Panthera leo) and giraffes (Giraffa camelopardalis). Importantly, an emergent disease called giraffe skin disease (GSD) may affect predatory interactions of lions and giraffes. Hypotheses suggest that GSD may negatively affect the likelihood of giraffes surviving lion attacks. We evaluated giraffe–lion interactions in Ruaha National Park, Tanzania, where 85% of the giraffe population has GSD. We monitored lion hunting behaviour and estimated proportion of the giraffe population with GSD and evidence of ‘lion marks’ from assumed previous lion predation attempts (i.e. claw marks, bite marks and missing tails). Although we recorded lions hunting and feeding on 16 different prey species, giraffes represented the largest prey category (27%; n = 171 of 641). For age and sex cohorts combined, 26% (n = 140 of 548) of encountered giraffes displayed evidence of previous lion predation attempts. Occurrence of lion marks was higher for adults and males in the giraffe population, suggesting that these individuals were more likely to survive lion attacks. We also found marginal evidence of a positive relationship between giraffes with severe GSD and occurrence of lion marks. Our results identify giraffes as important prey species for lions in Ruaha National Park and suggest that GSD severity plays a minor role in likelihood of surviving a lion attack. This is the first study to explore connections between lion predation and GSD. We explore the ecological implications of disease ecology on predator–prey interactions and consider opportunities for future research on causal links between GSD and giraffe vulnerability to lion predation.

We discuss the principal issues of intergenerational inequity of nature and wild places. We focus on the broader issue regarding the decrease in nature-based experiences future generations will face, and how the lack of such experiences will shape the future of biodiversity conservation. Throughout this manuscript we use biodiversity –the variety and variability of life on Earth– and species –the key units representing biodiversity– somewhat interchangeably to broaden the understanding of this paper beyond the scientific community.
Understanding nuanced preferences for carnivore conservation: To know them is not always to love them

Global Ecology and Conservation, Volume 37, e02150
In a study of more than 3000 participants from nine countries, we explored peoples’ preferences for the conservation of two groups of species that frequently interact with humans: large carnivores (n = 29 species in the order Carnivora with average adult body mass > 15 kg), and wild canids and wild felids (n = 73 species). We presented participants with pairs of photographs and recorded which they would prioritise for conservation. We also attempted to identify the species attributes which were associated with preference. Among the large carnivores, respondents prefered felids over hyaenids and canids. For large carnivores, images of species in social groups attracted lower preference scores. Felids were strongly preferred to canids. Both for large carnivores overall, and for felids and canids, people preferred species with a more threatened IUCN status, larger body size and striking torso colouration. The effect of peoples’ familiarity with a species on their preference depended on their affinity with it (how much they reported ‘liking’ it). Where respondents reported liking a species in the felid/canid study, preference score tended to increase with familiarity. For species which were not liked, preference declined with familiarity. We propose that this reflects negative experiences or cultural histories. There were nuanced differences in conservation preferences between countries, which may also arise from socio-cultural factors. These findings reinforce the importance of understanding the local context when identifying species as potential flagships for wildlife conservation but also suggest that some preferences seem to broadly generalise across different groups of stakeholders.
What is a lion worth to local people–Quantifying of the costs of living alongside a top predator

Ecological Economics, Volume 198, p. 107431
The presence of large predators entails a range of costs and some benefits for the communities that live alongside them. The cost in terms of the value of livestock lost to predation is well known, but this represents only a part of the costs that people experience, as it does not account for non-market costs such as fear, avoidance behaviours and threat to human life. We quantify the total cost of lion presence for agro-pastoral communities in Zimbabwe using economic valuation techniques. The total perceived value of one additional lion was estimated to be negative US$180 per person per year, which is several hundred times larger than the market value of the average loss of livestock per household. If making simplifying economic assumptions, this discrepancy reveals the magnitude of the non-market costs associated with the presence of large predators. The disvalue of lion presence was linked to fear, ecocentric values, wealth and trust in compensation institutions. We also demonstrate the importance of considering heterogeneity in preferences within communities; segments of the population did not have net negative value attached to lions, and some disliked monetary compensation. We also estimate the willingness-to-accept for two human-wildlife conflict mitigation programs in terms of acceptable increases in lion numbers, as opposed to monetary units which is the conventional approach in economic valuation studies. We argue that estimating value in terms of biodiversity outcomes should be used more widely. We also demonstrate the distorting effect of distrust towards compensation in choice experiments and argue that economic valuation methods employing choice experiments should control for this distrust when estimating willingness-to-pay. These discoveries have relevance for a wide range of situations where potentially dangerous wildlife species co-exist with people.

We use comparable 2005 and 2018 population data to assess threats driving the decline of lion Panthera leo populations, and review information on threats structured by problem tree and root cause analysis. We define 11 threats and rank their severity and prevalence. Two threats emerged as affecting both the number of lion populations and numbers within them: livestock depredation leading to retaliatory killing of lions, and bushmeat poaching leading to prey depletion. Our data do not allow determination of whether any specific threat drives declines faster than others. Of 20 local extirpations, most were associated with armed conflicts as a driver of proximate threats. We discuss the prevalence and severity of proximate threats and their drivers, to identify priorities for more effective conservation of lions, other carnivores and their prey.

Accurate and precise estimates of population status are required to inform and evaluate conservation management and policy interventions. Although the lion (Panthera leo) is a charismatic species receiving increased conservation attention, robust status estimates are lacking for most populations. While for many large carnivores population density is often estimated through spatially explicit capture–recapture (SECR) applied to camera trap data, the lack of pelage patterns in lions has limited the application of this technique to the species.
Here, we present one of the first applications of this methodology to lion, in Tanzania's Ruaha-Rungwa landscape, a stronghold for the species for which no empirical estimates of status are available. We deployed four camera trap grids across habitat and land management types, and we identified individual lions through whisker spots, scars and marks, and multiple additional features.
Double-blind identification revealed low inter-observer variation in photo identification (92% agreement), due to the use of xenon-flash cameras and consistent framing and angles of photographs.
Lion occurred at highest densities in a prey-rich area of Ruaha National Park (6.12 ± SE 0.94 per 100 km2), and at relatively high densities (4.06 ± SE 1.03 per 100 km2) in a community-managed area of similar riparian-grassland habitat. Miombo woodland in both photographic and trophy hunting areas sustained intermediate lion densities (1.75 ± SE 0.62 and 2.25 ± SE 0.52 per 100 km2, respectively). These are the first spatially explicit density estimates for lion in Tanzania, including the first for a trophy hunting and a community-managed area, and also provide some of the first insights into lion status in understudied miombo habitats.
We discuss in detail the methodology employed, the potential for scaling-up over larger areas, and its limitations. We suggest that the method can be an important tool for lion monitoring and explore the implications of our findings for lion management.

Coexistence with large carnivores poses challenges to human well-being, livelihoods, development, resource management, and policy. Even where people and carnivores have historically coexisted, traditional patterns of behavior toward large carnivores may be disrupted by wider processes of economic, social, political, and climate change. Conservation interventions have typically focused on changing behaviors of those living alongside large carnivores to promote sustainable practices. While these interventions remain important, their success is inextricably linked to broader socio-political contexts, including natural resource governance and equitable distribution of conservation-linked costs and benefits. In this context we propose a Theory of Change to identify logical pathways of action through which coexistence with large carnivores can be enhanced. We focus on Africa's dryland landscapes, known for their diverse guild of large carnivores that remain relatively widespread across the continent. We review the literature to understand coexistence and its challenges; explain our Theory of Change, including expected outcomes and pathways to impact; and discuss how our model could be implemented and operationalized. Our analysis draws on the experience of coauthors, who are scientists and practitioners, and on literature from conservation, political ecology, and anthropology to explore the challenges, local realities, and place-based conditions under which expected outcomes succeed or fail. Three pathways to impact were identified: (a) putting in place good governance harmonized across geographic scales; (b) addressing coexistence at the landscape level; and (c) reducing costs and increasing benefits of sharing a landscape with large carnivores. Coordinated conservation across the extensive, and potentially transboundary, landscapes needed by large carnivores requires harmonization of top-down approaches with bottom-up community-based conservation. We propose adaptive co-management approaches combined with processes for active community engagement and informed consent as useful dynamic mechanisms for navigating through this contested space, while enabling adaptation to climate change. Success depends on strengthening underlying enabling conditions, including governance, capacity, local empowerment, effective monitoring, and sustainable financial support. Implementing the Theory of Change requires ongoing monitoring and evaluation to inform adaptation and build confidence in the model. Overall, the model provides a flexible and practical framework that can be adapted to dynamic local socio-ecological contexts.

When navigating heterogeneous landscapes, large carnivores must balance trade-offs between multiple goals, including minimizing energetic expenditure, maintaining access to hunting opportunities and avoiding potential risk from humans. The relative importance of these goals in driving carnivore movement likely changes across temporal scales, but our understanding of these dynamics remains limited.
Here we quantified how drivers of movement and habitat selection changed with temporal grain for two large carnivore species living in human-dominated landscapes, providing insights into commonalities in carnivore movement strategies across regions.
We used high-resolution GPS collar data and integrated step selection analyses to model movement and habitat selection for African lions Panthera leo in Laikipia, Kenya and pumas Puma concolor in the Santa Cruz Mountains of California across eight temporal grains, ranging from 5 min to 12 hr. Analyses considered landscape covariates that are related to energetics, resource acquisition and anthropogenic risk.
For both species, topographic slope, which strongly influences energetic expenditure, drove habitat selection and movement patterns over fine temporal grains but was less important at longer temporal grains. In contrast, avoiding anthropogenic risk during the day, when risk was highest, was consistently important across grains, but the degree to which carnivores relaxed this avoidance at night was strongest for longer term movements. Lions and pumas modified their movement behaviour differently in response to anthropogenic features: lions sped up while near humans at fine temporal grains, while pumas slowed down in more developed areas at coarse temporal grains. Finally, pumas experienced a trade-off between energetically efficient movement and avoiding anthropogenic risk.
Temporal grain is an important methodological consideration in habitat selection analyses, as drivers of both movement and habitat selection changed across temporal grain. Additionally, grain-dependent patterns can reflect meaningful behavioural processes, including how fitness-relevant goals influence behaviour over different periods of time. In applying multi-scale analysis to fine-resolution data, we showed that two large carnivore species in very different human-dominated landscapes balanced competing energetic and safety demands in largely similar ways. These commonalities suggest general strategies of landscape use across large carnivore species.
