Factors affecting crossing structure use by khulan and goitered gazelle in China

Quantifying the utilization of wildlife crossing structures (CSs) requires considering the local population background. This study assessed the effectiveness of 22 CSs based on the abundance of two ungulates (khulan and goitered gazelle) in northwestern China and analyzed variables influencing their usage such as openness, water source, and human activities in drylands. Results showed that there were 7 and 13 CSs with higher performance indices (PRi) for khulan and goitered gazelle, respectively. Khulan favors CSs near water sources and with large openness, while goitered gazelle prefers structures that include ponding and also feature large openness. Factors like distance to the CSs of the railway, predators, and human activities affect the utilization of CSs by goitered gazelle. This study emphasized the importance of designing and managing effective wildlife CSs by focusing on openness and water resources. It is recommended that CSs can be spatially consistent in multiple transportation lines run parallel.

Wildfire influences species assemblage and habitat utilisation of boreal wildlife after more than a decade in northern Sweden

Fires can strongly change the vegetation structure and the availability of resources for wildlife, but fire suppression has long affected the natural role of fire in shaping boreal ecosystems in northern Europe. Recently, wildfires have increased in frequency, possibly due to global warming. In contrast to the boreal systems in North America, there have been few studies on responses of wildlife to wildfires in northern Europe. Based on the findings from North America, we predict that responses of wildlife to wildfire vary among wildlife species: where mammalian herbivores, such as moose Alces alces and mountain hare Lepus timidus, will be attracted to burnt areas following an increase in food availability, other species, such as reindeer Rangifer tarandus, are negatively impacted due to fire reducing their preferred food. We then tested our predictions by contrasting wildlife utilization of sites that burnt by wildfire in 2006 with nearby unburnt control sites in three areas in northern Sweden. To measure wildlife utilization, we used 72 camera traps, equally divided between the burnt and control sites, with two placement strategies: random and on wildlife trails. The cameras recorded 27 mammal and bird species during summer 2018. Species assemblage differed between burnt and control sites. Fieldfare Turdus pilaris used burnt sites more than control sites, while pine marten Martes martes and western capercaillie Tetrao urogallus used control sites more than burnt sites. We however did not find support for a positive effect of past forest fires on any of the observed wild mammals. We discuss how, due to the impact of forestry, forage‐rich habitat may not be as limiting in Scandinavia as in the North‐American context, potentially leading to recently burnt sites being less attractive to herbivores such as moose.

Utilization Practices and Conservation Impacts of Endangered Wildlife in Asian Countries

The Asian region is globally renowned for its unparalleled biodiversity, rich ecosystems, and unique cultural heritage. However, the delicate equilibrium between human societies and the diverse flora and fauna faces increasing challenges due to the region's rich biodiversity and escalating utilization of wildlife resources. Hence, this paper aims to document the utilization of endangered wildlife across Asian countries and to report the existing conservation measures and recommendations for sustainable wildlife management over the years. We employed prominent academic databases, specifically SCOPUS, to explore the dynamics of wildlife utilization and its associated implications. From the findings, 9,989 records were successfully identified. However, only 65 articles were included in the review after the screening process. A total of 61 species, comprising 30 mammals, 22 reptiles, one amphibian, and eight birds, all endangered, were identified as subjects of wildlife utilization in 16 Asian countries. China possessed the highest count for wildlife utilization across all categories, including 15 species used for trading purposes. In conclusion, this research underscores the critical need for integrated approaches that balance human needs and conservation imperatives to ensure a sustainable future for Asia's wildlife biodiversity.

Occupancy model to unveil wildlife utilization at Yeongyang-gun wind farm management road, Korea

Wind power is a rapidly growing renewable energy sector that reduces greenhouse gas emissions and provides sustainable energy. However, environmental destruction in wind power plant areas, particularly in wind farms within forests, is an emerging issue. This study aimed to analyze the impact of wind-farm roads on terrestrial animals in forested areas. A camera trap survey was conducted to investigate the impact of road management on wildlife behavior. We installed 52 cameras along roads connecting wind turbines for three months (1st October to 30th December 2021) on the Yeongyang-gun wind farm in South Korea and evaluated animal occupancy and detection probabilities using an occupancy model. Factors related to terrain and vegetation were used to estimate the occupancy probability (station use). The detection analysis included the presence or absence of guardrails, wind turbines, shrublands, and retaining walls. Additional variables included camera type, number of camera-operating days, and survey time. During the survey period, seven terrestrial mammals (roe deer, wild boar, water deer, raccoon dogs, badgers, leopards, cats, and martens) were captured using cameras. Based on camera trap records, roe deer was the most dominant species, followed by wild boars, raccoon dogs, and water deer, with fewer badgers and martens. The presence of forests in the road area was a significant factor for most species in terms of use probability, and camera type was significant for detection probability. Detecting animals along roads shows that roads are passageways for wildlife, affecting animal behavior during vehicle movement and can cause habitat disconnection. Our results demonstrate that wind farms are indirectly linked to wildlife distribution and welfare. Effective management policies for mitigating wildlife disruption can support sustainable ecosystems and biodiversity. The results of this study can serve as a reference for supporting wildlife conservation, terrestrial ecosystems, and environmental impact assessments.

The Factors Influencing Wildlife to Use Existing Bridges and Culverts in Giant Panda National Park

Roads, acting as barriers, hamper wildlife movements and disrupt habitat connectivity. Bridges and culverts are common structures on roads, and some of them can function to allow wildlife passage. This study investigated the effects of traffic, the surrounding landscape, human disturbance, and bridge and culvert structures on the utilization of bridges and culverts as dedicated passages by wildlife, using motion-activated infrared camera traps along a 64 km road in Giant Panda National Park, Sichuan, China. The results show that both species richness and counts of wildlife recorded at the bridge and culvert were significantly lower than those observed at sites distant from roads. No large-sized wildlife was recorded at the bridges and culverts. Human activities and traffic volume significantly and negatively affect medium-sized wildlife utilization of bridges and culverts. We conclude that bridges and culverts serve as wildlife crossings, but their efficacy is weak. This emphasizes the necessity of retrofitting bridges and culverts via mitigation facilities such as noise and light barriers, and vegetation restoration on both sides of the roads in Giant Panda National Park.

The Role of Training in Harmonizing Views Regarding Traditional Consumptive Uses of Wildlife among Students at the Kenya Wildlife Service Training Institute

A two step study was conducted in October 2021 to determine views of pre-service and in-service students regarding consumptive wildlife utilization in Kenya. Pre-service respondents were fresh school leavers while in-service respondents were rangers employed by the Kenya Wildlife Service. A self-administered, closed ended, drop-and-collect questionnaire was used to obtain data on students’ views regarding traditional consumptive uses of wildlife just before and after their 18 month diploma in wildlife management program at the Kenya Wildlife Service Training Institute. Respondents were required to indicate whether they supported or opposed t use of wildlife as (i) source of meat for human consumption, (ii) source of ceremonial wear, (iii) source of traditional medicine, (iv) source of ornaments, and (v) a sacrifice in religious ceremonies. A “not sure” option was provided for respondents who were undecided about an item. Questionnaire return rate was 100% for both studies with a respondent number of 30 for the first and 28 for the second study respectively. Before their training, pre-service students strongly supported consumptive wildlife use while in-service students strongly supported non-consumptive use. After their training however, both pre-service and in-service students were strongly supportive of non-consumptive wildlife use. The shift in views of pre-service students was associated with the knowledge, attitudes and values imparted in them during their training. More related studies are recommended.

Spatial heterogeneity and socioeconomic transformation challenge the prevention of illegal wildlife consumption in China

Wildlife can be viewed as a renewable resource at ecologically viable levels, but illicit consumption is a major threat to global biodiversity. Using data from crime cases is an emerging new tool for assessing the motives and drivers of wildlife offenders. This approach can be used with behavior change frameworks to devise more effective conservation strategies. We used data from 20,145 online judgments published between 2014 and 2019 to determine the spatial distribution of different wildlife crime and illegal consumption patterns across China, and used multiscale modeling to test the effects of socioeconomic, geographic, and demographic correlates. The results indicated that geographic indicators and agricultural practices had a broad and positive impact on wildlife consumption, implying wildlife availability was a powerful incentive for wildlife crimes. In addition, urbanization and industrial structure were regionally sensitive in predicting convictions for wild meat, traditional medicine, and human-nature conflicts. Given the socioeconomic transformation in modern China, we predict that functional approaches of wildlife utilization will decrease in the coming years, but the illegal consumption characterized by financial and spiritual demand is unlikely to diminish. As a response, the prevention strategy should strengthen law enforcement on non-functional consumption and enhance nature education campaigns among youths across the country.

Unpacking the challenges of wildlife governance in community‐based conservation programs to promote human–wildlife coexistence

AbstractOne of the numerous global challenges today is how to promote biodiversity persistence and at the same time reduce poverty and improve livelihoods, especially in multiple‐use landscapes shared by people and wildlife. In such landscapes, where the cost of sharing the landscape with large wildlife can be high, Community Based Natural Resource Management (CBNRM) program is a model promoted to offset negative wildlife impacts. However, such programs, that promote sustainable utilization of wildlife, are not always successful. To better understand how CBNRM governance systems enable or hinder human–wildlife coexistence, I implemented an 11‐weeks participatory co‐learning program in conservancies in the Zambezi region of Namibia. Framing human–wildlife relationships as occurring within complex social–ecological systems, participatory dialogues were used to unpack the system to better understand why human–wildlife conflict remains a challenge after 30 years of CBNRM in Namibia. From listening to communities I identified five key areas requiring improvement: (1) inefficient communication and transfer of information between management and community; (2) lack of policy and process clarity; (3) lack of support, knowledge, resources, and implementation of mitigation measures; (4) lack of accountability by both management and conservancy members; and (5) lack of skills and capacity by both management and conservancy members. To address these problem areas, I propose three key priority actions: (1) harmonize conservancy policies and management practices; (2) improve information flow; and (3) implement an adaptive management mitigation measure program. While this study focused on a small part of Namibia, I expect this methodology and many of the key findings and proposed interventions will be relevant for other areas applying collaborative approaches to improve human–wildlife coexistence.

Evaluating the role of active management in mature Douglas-fir (Pseudotsuga menziesii) stands for songbird conservation

Forest birds, particularly those associated with late-successional forests, are of widespread conservation interest. Although birds are among the more widely studied taxa of forest wildlife, relatively few studies have examined the long-term effects of active management (i.e., intentional stand density reduction) on the forest bird assemblage. This is an important omission, as changes in stand structure and composition over the decades following harvesting may influence wildlife utilization of forest stands. We developed an observational study to evaluate forest bird response to stand structural development multiple decades following harvesting with differing levels of overstory density reduction, and in unmanaged stands. We focused, in particular, on songbirds and cavity excavating species associated with old-growth Douglas-fir forests, and the active management strategies that we examined – thinning and structural retention harvesting – were selected based on their potential to accelerate stand structural development. Our 18 mature stands (age range: 107–187 years) were located in the western hemlock zone of western Oregon, and bird surveys were conducted an average of 41 years and 22 years post-harvest in thinned and retention harvest stands, respectively. Poisson generalized linear models were formulated to evaluate the effects of management condition on forest birds. Although five species were associated with specific management conditions, relative abundance was not statistically different between unmanaged, thinned and retention harvest stands for a majority of the species in our analysis. Species richness was also relatively invariant across management conditions. Our results do suggest that retention harvesting adversely affects some songbird species associated with old-growth forests – Pacific-slope flycatcher (Empidonax difficilis) and Pacific wren (Troglodytes pacificus) for example - but our findings also indicate that retention harvesting has long-term benefits for birds associated with early-successional forests. This includes migrant species that have experienced significant population declines in Western North America over recent decades, such as Wilson’s and MacGillivray’s warblers (Cardellina pusilla and Geothlypis tolmiei, respectively). Overall, our results imply that for many species of forest birds, including those associated with old-growth forests, managers have some flexibility in overstory density management where long-term species persistence is an objective. Equally significant, our results provide strong support for the application of variable retention harvesting as a tool for the conservation of bird species associated with early-successional forests, while also reinforcing the value of mature structural legacies for bird species associated with late-successional forests. While also reinforcing the value of mature structural legacies for birds associated with late-successional forests.

The Impact of Information on Attitudes toward Sustainable Wildlife Utilization and Management: A Survey of the Chinese Public.

Simple SummaryThe widespread dissemination of information related to wildlife utilization in new online media and traditional media undoubtedly impacts societal conservation concepts and attitudes, thus triggering public discussions on the relationship between conservation and utilization. In this study, questionnaires were distributed in seven major geographic regions of Chinese mainland to investigate the public’s awareness and agreement with information related to the utilization of wildlife in order to measure the impact of information on various issues relating wildlife conservation and utilization. The Chinese public had the greatest awareness and agreement with information that prevents unsustainable and illegal utilization, and the least awareness and agreement with information that promotes unsustainable utilization. It is also noteworthy that the Chinese public have higher levels of awareness and agreement with information that does not support utilization than with information that supports sustainable utilization. From our research, we can conclude that overall the public tends to support and be informed by a purist view of conservation, and there is significantly less support for conservation based on sustainable utilization. On this basis, we suggest that in the future, conservation education should seek to balance the public’s respect and love for nature which is often inspired by social media, with more scientific information about scientific understandings that influence conservation policy and practice.The widespread dissemination of information related to wildlife utilization in new online media and traditional media undoubtedly impacts societal conservation concepts and attitudes, thus triggering public discussions on the relationship between conservation and utilization. A study on how public attitudes and concepts are affected by the related information on wildlife utilization is helpful to implement the scientific wildlife conservation and management strategies, and to propose targeted measures to optimize the information environment. We designed the questionnaire to investigate the public’s awareness and agreement with related information on wildlife utilization so as to measure how information with different dissemination channels, source types, and content orientation influenced the public’s concept of wildlife conservation and utilization. The questionnaire was distributed in seven major geographical regions throughout China. Out of a total of 1645 questionnaires that were collected, 1294 questionnaires were valid, with an effective rate of 78.7%. Results show that respondents had the greatest awareness of information on preventing unsustainable and illegal utilization, and the lowest awareness of information on promoting unsustainable utilization, and that awareness of information that against utilization was higher than that of information which supported sustainable utilization. At the same time, respondents showed the greatest agreement for information on preventing unsustainable utilization and the lowest agreement for information on promoting unsustainable utilization; also, their agreement with information that against utilization was higher than that for information which supported sustainable use. Respondents had a high level of awareness of information on wildlife related to COVID-19 provided by experts. Gender, age, the level of development of the city in which they live, education, vegetarianism, and religious beliefs all affected respondents’ agreement with related information on wildlife utilization. This research suggests that the publicity and education of scientific conservation methods should be emphasized in the future conservation education. In addition, scholars in the field of wildlife research should assume the role of ‘influencer’ and give full play to the scientific guidance of public opinion.

Compassionate Conservation and the Challenge of Sustainable Wildlife Management: A Survey of the Urban Public of China.

Simple SummarySustainable wildlife management (SWM), based on traditional practice supported with advances in scientific knowledge and evolving economic and social circumstances, has shaped the global approach to wildlife management and policy. In this paper, we report the findings of a large semi-structured questionnaire in China which investigated the attitude of the urban public toward sustainable wildlife management and wildlife conservation across a range of issues and identified the key socio-economic and demographic factor drivers for those attitudes. The survey was conducted from November 2018 to October 2020, across 15 cities randomly selected among China’s seven administrative geographic regions. The survey was initially conducted through face-to-face interviews, but later, due to COVID-19 restrictions, was completed via online questionnaires. The results show that the public are broadly supportive of the theory of SWM, but their enthusiasm is issue- and context-dependent. For example, on issues of “Animal Welfare and Rights,” “Wildlife Utilization and Captive Breeding,” and “Trophy Hunting”, the public demonstrate antagonistic views about SWM, demonstrating an affinity for “Compassionate Conservation”. We also found that demographic characteristics of the public can significantly influence attitude, with those respondents who are not vegetarian or religious, who have higher levels of education, or are younger in age being more likely to appreciate the rational science approach of SWM. Our research suggests that conservation organisations may need to adapt their management aims and practices to avoid direct conflict with the rising tide of animal rights sentiment. Furthermore, significant investment will be required to promote science-based conservation in social marketing on all social media platforms to help educate and engage the public with the science behind conservation management.Sustainable wildlife management (SWM) is based on a synergy of traditional/local knowledge, advances in scientific knowledge, and fast-evolving economic and social circumstances. A widely accepted cornerstone of SWM globally is that conservation and utilization need to be effectively integrated, emphasizing the benefits humans can derive from biodiversity, thereby further encouraging people to protect and value wildlife though its management. However, with demand from biological resources growing at an unprecedented rate and the emergence of social media, conservationists must respond quickly to new challenges and conflicts associated with species management and public policy. For example, the rise of the “Compassionate Conservation” (CC) movement, fueled by social marketing and media, which promotes the welfare of individual animals, has introduced a set of challenges for conventional conservation management as it opposes most or all forms of wildlife utilization and hunting. CC advocates are increasingly influential at global and national policy levels; hence, it is imperative that conservationists are informed and aware of the future challenges from a rapidly changing global society. In this paper, we report the findings of a large semi-structured questionnaire in China which investigated the attitude of the urban public toward sustainable wildlife management (SWM) and wildlife conservation across a range of issues and identified the key socio-economic and demographic factor drivers for those attitudes. The survey was conducted from November 2018 to October 2020, across 15 cities randomly selected among China’s seven administrative geographic regions. The survey was initially conducted through face-to-face interviews, but later, due to COVID-19 restrictions, was completed via online questionnaires. A Likert seven-point scale method was used to score the public’s degree of agreement or disagreement for each question; a multivariate stepwise linear regression method was used to analyze whether the overall attitude of the respondents toward SWM and wildlife conservation was affected by their demographic characteristics; and a classification and regression tree (CART) was used to conduct an in-depth analysis of the issues with negative scores in the questionnaire, so as to understand how the respondents’ demographic characteristics affected the public’s attitude about such issues, which could supplement results obtained from the multivariate stepwise linear regression analysis. The results show that the public are broadly supportive of SWM, but only moderately so. On issues of “Animal Welfare and Rights,” “Wildlife Utilization and Captive Breeding,” and “Trophy Hunting”, the core concerns of the “Compassionate Conservation” movement and the overall public view are more antagonistic to conventional SWM. We also find specific demographic characteristics significantly influence attitudes about SWM, with vegetarians, those with religious beliefs, and with lower educational standards demonstrating weaker support for SWM. For younger people, “Animal Welfare and Rights” is a special concern, hence, we identify this as a key issue to be addressed for SWM and conservation in the future. Our research suggests that conservation organisations may need to adapt their management aims and practices to avoid direct conflict with the rising tide of animal rights sentiment, especially among the young. Furthermore, significant investment will be required to promote science-based conservation in social marketing on all social media platforms to help educate and engage the public with the science behind conservation management.

China’s Conservation Strategy Must Reconcile Its Contemporary Wildlife Use and Trade Practices

China’s supply-side conservation efforts in the past decades have led to two bewildering juxtapositions: a rapidly expanding farming industry vs. overexploitation, which remains one of the main threats to Chinese vertebrates. COVID-19 was also the second large-scale zoonotic disease outbreak since the 2002 SARS. Here, we reflect on China’s supply-side conservation strategy by examining its policies, laws, and practices concerning wildlife protection and utilization, and identify the unintended consequences that likely have undermined this strategy and made it ineffective in protecting threatened wildlife and preventing zoonotic diseases. We call for China to overhaul its conservation strategy to limit and phase out risky and unsustainable utilization, while improving legislation and enforcement to establish full chain-of-custody regulation over existing utilization.

The dissemination of relevant information on wildlife utilization and its connection with the illegal trade in wildlife

We analyzed the generation and dissemination of relevant information on wildlife utilization based on the African bush elephant (Loxodonta africana Blumenbach.), the tiger (Panthera tigris L.) and the totoaba, a species of marine fish, (Totoaba macdonaldi Gilbert) as examples, whose populations are more threatened by the illegal wildlife trade. We compared the illegal trade in wildlife with related information in order to find possible associations, searched for relevant information on major international websites to summarize similarities in information production and dissemination, and used a “Zhiwei” dissemination analysis platform to analyze the dissemination of information circulated at Microblog. The results show that the most influential information related to the trade in wildlife is mainly generated from news media websites and new self-media platforms, usually from non-governmental organizations concerned with wildlife protection. The main factors that affect the depth and breadth of disseminating relevant information on wildlife utilization include the participation of relatively influential opinion leaders, the verification ratio of forwarding users, the number of followers, and affective identification. Misleading information can stimulate and promote poaching and smuggling, regardless of their real market demand or their products. Therefore, all links in the course of information dissemination should be carefully examined in order to purify the information environment and reduce adverse effects of misleading information on wildlife protection.

Physical factors at salt licks influenced the frequency of wildlife visitation in the Malaysian tropical rainforest

Mineral reservoirs or salt licks are commonly used by wildlife to regulate the concentration of salt and minerals in their bodies. Salt lick utilisation is known to be influenced by the chemical composition, but information on their physical properties, particularly vegetation surrounding the salt licks is scarce. In this study, physical factors and wildlife utilisation at two natural salt licks (SPU and SPS) located in Perak, Malaysia, were determined. Wildlife visitation data were retrieved from camera traps. SPU exhibits two reservoirs represented by rocky and clay substrate, with minimally dense vegetation dominated by hardwood species and climbers. SPS encompasses muddy topsoil, open canopy cover, with highly dense forest floor vegetation. The wildlife survey shows a higher frequency of visitation in SPS, especially by ungulates, potentially due to dense understorey foliage that provides foraging sites for these animals. SPU exhibits more diverse but less frequent wildlife species, particularly primates, carnivores, and avian groups. High emergence and closed canopy cover at this lick serve as perching sites for primates and birds, while less dense understory vegetation could aid in prey detection among carnivore. Regardless of their physical assemblages, salt licks are an essential local hotspot for wildlife, therefore, elucidating the need to prioritise conservation areas by maximising the complementarities of salt licks.

Wildlife Hunting and Utilization in Ulu Baleh, Sarawak, Malaysian Borneo

Poaching is one of the greatest immediate threats and a serious conservation challenge facing wildlife in Borneo. Medium- to large-sized mammals, while charismatic, are hunted for consumption and sale. This study focuses on wildlife hunting and utilization of selected communities in a remote area in Sarawak, conducted using interview surveys within communities who hunt wildlife in Ulu Baleh. The calculated hunting pressure index in Ulu Baleh (2.24) is considered low compared to other parts of Sarawak. Local communities are dependent on wildlife protein and medicine. Even though the common hunting offtake included the bearded pig and deer species, for the hunter’s own consumption, hunters were opportunistic in taking non-target species and selling surplus meat. Lack of awareness of the implications of unsustainable hunting and difficulty in monitoring by the relevant authorities appear to be the main challenges to wildlife conservation in the area. This paper highlights the lack of research documenting wildlife utilization in the Ulu Baleh region and the implication of these results are particularly important for future adaptive wildlife management, especially for species of conservation importance in Sarawak.

Genetic diversity, relatedness and inbreeding of ranched and fragmented Cape buffalo populations in southern Africa.

Wildlife ranching, although not considered a conventional conservation system, provides a sustainable model for wildlife utilization and could be a source of valuable genetic material. However, increased fragmentation and intensive management may threaten the evolutionary potential and conservation value of species. Disease-free Cape buffalo (Syncerus caffer caffer) in southern Africa exist in populations with a variety of histories and management practices. We compared the genetic diversity of buffalo in national parks to private ranches and found that, except for Addo Elephant National Park, genetic diversity was high and statistically equivalent. We found that relatedness and inbreeding levels were not substantially different between ranched populations and those in national parks, indicating that breeding practices likely did not yet influence genetic diversity of buffalo on private ranches in this study. High genetic differentiation between South African protected areas highlighted their fragmented nature. Structure analysis revealed private ranches comprised three gene pools, with origins from Addo Elephant National Park, Kruger National Park and a third, unsampled gene pool. Based on these results, we recommend the Addo population be supplemented with disease-free Graspan and Mokala buffalo (of Kruger origin). We highlight the need for more research to characterize the genetic diversity and composition of ranched wildlife species, in conjunction with wildlife ranchers and conservation authorities, in order to evaluate the implications for management and conservation of these species across different systems.

Incorporating social-ecological complexities into conservation policy

In the process of developing new conservation policies, policymakers must have access to information which will inform their decisions. Evidence rarely considers the complexities of social-ecological systems. The Social-Ecological Systems Framework (SESF) is an adaptable yet structured approach for understanding the processes that lead to changes in natural resources, using a systems-based approach that aims to treat ecological and social components equally. Few conservation planning and policy initiatives have implemented the SESF to assess the interlinked social and ecological consequences of conservation policies. We apply the SESF to explore the barriers to the potential implementation of a policy of consumptive utilisation of wildlife in Kenya, a policy regarded as successful in several southern African countries. Using secondary data and expert review we developed a conceptual model of the social-ecological system associated with consumptive utilisation of wildlife in Kenya. We then analysed how different combinations of first and second-tier variables interacted to create focal action situations, and subsequently identified seven barriers to this policy. Our analysis revealed that game ranching would require large-scale investment in effective monitoring systems, new regulations, training, market development and research, considerations about equity, and devolved ownership of wildlife. The least barriers existed for game farming. The SESF appears to be a useful framework for this purpose. In particular, it can help to reveal potential social and ecological barriers which conservation policies might face in attempting to meet intended goals. The information required to implement the SESF are necessarily cross-disciplinary, which can make it challenging to synthesise.

Ethical Considerations for Wildlife Reintroductions and Rewilding.

The recovery of many populations of large carnivores and herbivores in major parts of Europe and North America offers ecosystem services and opportunities for sustainable utilization of wildlife. Examples of services are hunting, meat, and skin, along with less invasive utilization such as ecotourism and wildlife spotting. An increasing number of studies also point out the ecosystem function, landscape engineering, and cascading effects of wildlife as values for human existence, biodiversity conservation, and ecosystem resilience. Within this framework, the concept of rewilding has emerged as a means to add to the wilderness through either supplementary release of wildlife species already present or reintroduction of species formerly present in a certain area. The latter involves translocation of species from other geographical areas, releases from captivity, feralization, retro-breeding, or de-domestication of breeds for which the wild ancestor is extinct. While all these initiatives aim to reverse some of the negative human impacts on life on earth, some pose challenges such as conflicts of interest between humans and wildlife in, for example, forestry, agriculture, traffic, or disease dynamics (e.g., zoonosis). There are also welfare aspects when managing wildlife populations with the purpose to serve humans or act as tools in landscape engineering. These welfare aspects are particularly apparent when it comes to releases of animals handled by humans, either from captivity or translocated from other geographical areas. An ethical values clash is that translocation can involve suffering of the actual individual, while also contributing to reintroduction of species and reestablishment of ecological functions. This paper describes wildlife recovery in Europe and North America and elaborates on ethical considerations raised by the use of wildlife for different purposes, in order to find ways forward that are acceptable to both the animals and humans involved. The reintroduction ethics aspects raised are finally formulated in 10 guidelines suggested for management efforts aimed at translocating wildlife or reestablishing wilderness areas.
