Spatial ecology of conflicts
Human encroachment into natural habitats is typically followed by conflicts derived from wildlife damage to agriculture and livestock. Spatial risk modelling is a useful tool to gain the understanding of wildlife damage and mitigate conflicts. Although resource selection is a hierarchical process operating at multiple scales, risk models usually fail to address more than one scale, which can result in the misidentification of the underlying processes. Here, we addressed the multi-scale nature of wildlife damage occurrence by considering ecological and management correlates interacting from household to landscape scales. We studied brown bear (Ursus arctos) damage to apiaries in the North-eastern Carpathians as our model system. Using generalized additive models, we found that brown bear tendency to avoid humans and the habitat preferences of bears and beekeepers determine the risk of bear damage at multiple scales. Damage risk at fine scales increased when the broad landscape context also favoured damage. Furthermore, integrated-scale risk maps resulted in more accurate predictions than single-scale models. Our results suggest that principles of resource selection by animals can be used to understand the occurrence of damage and help mitigate conflicts in a proactive and preventive manner.
Mapping opportunities and barriers for coexistence between people and pumas in the Argentine Dry Chaco
Aim The persistence of large carnivore populations depends on their survival outside protected areas, where they often impact local livelihoods through livestock depredation. Understanding the impacts of human behaviour on large carnivores in shared landscapes is thus important but is often overlooked in habitat assessments or conservation planning. We employed an integrated approach that considers human behaviour and landscape structure metrics to assess the potential for human‐puma (Puma concolor) coexistence in the Chaco region, a global deforestation and defaunation hotspot. Location Argentine Dry Chaco (~490,000 km2). Methods We identified suitable puma habitat patches and movement areas using occupancy modelling and combined it with a spatial human‐puma conflict risk model based on interview data to identify ‘safe’ and ‘unsafe’ habitat patches. We then used resistance surfaces to identify ‘safe’ and ‘unsafe’ movement areas, as well as ‘severed’ movement areas where anthropogenic land conversion inhibits movement. Results Safe puma habitat patches (i.e., suitable and safe) covered 29% of the region, whereas attractive sinks (i.e., suitable but risky) represented 12%. Movement areas corresponded to 60% of the region, while conflict risk and high landscape resistance undermined connectivity: unsafe and severed movement areas covered 10% and 11% of the region, respectively. Nearly 98% of safe habitat and movement areas occurred outside protected areas. Main Conclusions We provide an integrated conceptual framework and spatial explicit template for a three‐pronged conservation strategy to (1) protect safe habitat and movement areas, (2) mitigate livestock depredation in attractive sinks and unsafe movement areas and (3) restore landscape in severed and matrix areas to improve ecological connectivity. This would allow pumas to maintain viable populations while reducing negative impacts on local people. More generally, we show how integrating habitat and conflict risk models can reveal opportunities and challenges for human‐carnivore coexistence beyond protected areas.
Exploring Convivial Conservation in Theory and Practice
Convivial conservation has been put forward as a radical alternative to transform prevailing mainstream approaches that aim to address global concerns of biodiversity loss and extinction. This special issue includes contributions from diverse disciplinary and geographical perspectives which critically examine convivial conservation’s potential in theory and practice and explore both possibilities and challenges for the approach’s transformative ambitions. This introduction focuses on three issues which the contributions highlight as critical for facilitating transformation of mainstream conservation. First, the different ways in which key dimensions of justice — epistemic, distributive, and participatory and multi-species justice — intersect with the convivial conservation proposal, and how potential injustices might be mitigated. Second, how convivial conservation approaches the potential to facilitate human and non-human coexistence. Third, how transformative methodologies and innovative conceptual lenses can be used to further develop convivial conservation. The diverse contributions show that convivial conservation has clear potential to be transformative. However, to realise this potential, convivial conservation must avoid previous proposals’ pitfalls, such as trying to ‘reinvent the wheel’ and being too narrowly focused. Instead, convivial conservation must continue to evolve in response to engagement with a plurality of perspectives, experiences, ideas and methodologies from around the world.
Should we feed wildlife? A call for further research into this recreational activity
Independent human–wildlife feeding interactions (i.e., the feeding of wildlife by the public outside of organized ecotourism activities) represent an increasingly common way in which humans and wildlife are engaging with one another. It is important to determine what effects these interactions are having on the wildlife involved in order to ensure that optimum coexistence scenarios are being achieved, however the nature of these interactions makes them notoriously difficult to study. Extrapolation from ecotourism activities has suggested detrimental impacts on the health and fecundity of the populations involved. Moreover, recent findings indicate that bold individuals may actually gain reproductive advantages from this excess food supply, driving artificial selection of risk‐taking behaviors within human‐dominated landscapes. Humans may, therefore, be unknowingly manipulating wildlife populations, forcing them into unnatural states, and potentially decreasing future viability. Here, we outline key literature pertaining to the potential impacts of these self‐led interactions on wildlife and address the need for further research into the associated effects. Due to the associated safety risks to the humans involved in these interactions, and by applying the precautionary principle until further research can be performed, we recommend that management actions be employed to actively reduce their occurrence. We address current management practices in use and make recommendations for further research to adapt and improve them. Ultimately, we make a call for further research addressing two fundamental key areas: (i) to explore the effects of these interactions on the wildlife involved, across different species and habitats experiencing this phenomenon, with emphasis on the potential role of artificial selection, and (ii) to work to improve the management practices currently employed to reduce the occurrence of these interactions, at least until such time as the effects of these interactions on both humans and wildlife have been thoroughly disentangled, with the overall goal of improving coexistence. The recreational feeding of wildlife marks an increasingly popular way in which humans directly interact with wild animals, including at‐risk species. However, the effects that this unmonitored provisioning of food may be having on the wildlife involved, or the most effective ways to manage associated conflict, remain understudied. Here, we outline information from the literature pertaining to these topics, and make a call for further research to fill noted holes in our knowledge.
Less bins, less baboons: reducing access to anthropogenic food effectively decreases the urban foraging behavior of a troop of chacma baboons (Papio hamadryas ursinus) in a peri-urban area
In South Africa, chacma baboons (Papio hamadryas ursinus) living near peri-urban areas may forage on anthropogenic food. Baboons have been recorded to damage crops, scatter waste from trash bins, and damage homes. A number of methods have been tested over the past 20 years to solve these problems, but none proved successful over the long-term or involved considerable costs. An efficient management system requires a detailed knowledge of how baboon troops proceed and organize during these urban foraging actions. This study examines the response of a troop of baboons to an experimental reduction of anthropogenic food sources in a peri-urban environment, the George campus of Nelson Mandela University (SA). We gradually suppressed access to waste food in trash cans, reducing the amount of anthropogenic food available. This change in food availability led baboons to modify their urban foraging strategy. They compensated for the lack of anthropogenic food by spending more time foraging on natural food and less time in urban areas. However, the troop still exploited waste-free areas during the experiment and even more when the conditions were normal again. Overall, these results show the ability of baboons to adapt to changes in anthropogenic food availability but also that they are highly dependent on this type of resource. Limiting its access is a mitigation strategy that humans must absolutely develop for reaching a high level of coexistence with baboons.
Assessing the impacts of recreation on the spatial and temporal activity of mammals in an isolated alpine protected area
The management objectives of many protected areas must meet the dual mandates of protecting biodiversity while providing recreational opportunities. It is difficult to balance these mandates because it takes considerable effort to monitor both the status of biodiversity and impacts of recreation. Using detections from 45 camera traps deployed between July 2019 and September 2021, we assessed the potential impacts of recreation on spatial and temporal activity for 8 medium‐ and large‐bodied terrestrial mammals in an isolated alpine protected area: Cathedral Provincial Park, British Columbia, Canada. We hypothesised that some wildlife perceive a level of threat from people, such that they avoid ‘risky times’ or ‘risky places’ associated with human activity. Other species may benefit from associating with people, be it through access to anthropogenic resource subsidies or filtering of competitors/predators that are more human‐averse (i.e., human shield hypothesis). Specifically, we predicted that large carnivores would show the greatest segregation from people while mesocarnivores and ungulates would associate spatially with people. We found spatial co‐occurrence between ungulates and recreation, consistent with the human shield hypothesis, but did not see the predicted negative relationship between larger carnivores and humans, except for coyotes (Canis latrans). Temporally, all species other than cougars (Puma concolor) had diel activity patterns significantly different from that of recreationists, suggesting potential displacement in the temporal niche. Wolves (Canis lupus) and mountain goats (Oreamnos americanus) showed shifts in temporal activity away from people on recreation trails relative to off‐trail areas, providing further evidence of potential displacement. Our results highlight the importance of monitoring spatial and temporal interactions between recreation activities and wildlife communities, in order to ensure the effectiveness of protected areas in an era of increasing human impacts. Protected areas have a dual mandate of providing recreational activities while also protecting wildlife and their habitats. We looked at the effects of human recreation on wildlife use of habitat in space and time, and found responses to recreation varied by species. Within one protected area, we saw that animals may be avoiding humans by shifting their use of habitat in time, more than in space.
Do human–wildlife interactions predict offspring hiding strategies in peri-urban fallow deer?
Human activities can induce significant behavioural changes in wildlife. Often explored through extractive interactions (e.g. hunting) that can favour certain behavioural traits, the implications of non-extractive ones, such as wildlife feeding, remain understudied. Research shows that people tend to favour bolder individuals within populations despite their dynamics and consequences being unclear. Using fallow deer in a peri-urban environment, we studied whether mothers that show reduced fear of humans and consistently approach them for food adopt weaker anti-predator strategies by selecting less concealed fawning bedsites closer to human hotspots. This would provide the advantage of additional feeding opportunities in comparison with shyer mothers while keeping their fawns close. Our dataset encompassed 281 capture events of 172 fawns from 110 mothers across 4 years. Surprisingly, mothers that regularly accepted food from humans selected more concealed bedsites farther from human hotspots, giving their offspring better protection while also benefitting from additional food during lactation. Our results show behavioural adaptations by a subset of females and, for the first time, link the tendency to approach humans and strategies to protect offspring. Given previous findings that these begging females also deliver heavier fawns at birth, our research further investigates human–wildlife feeding interactions and their behavioural implications.
High carnivore richness despite human pressure and prey depletion in the south-west of the Kavango–Zambezi Transfrontier Conservation Area
Transfrontier conservation landscapes, such as the Kavango–Zambezi Transfrontier Conservation Area (KAZA TCA) in southern Africa, play a crucial role in preserving global biodiversity and promoting the sustainable development of local communities. However, resources to facilitate management could become scarce across large areas, leading to difficulties in obtaining baseline ecological information. Consequently, in the absence of sustainable management vast landscapes may experience loss of wildlife species, which could destabilize ecosystems. This effect is particularly significant if the loss involves top predators. Hence, understanding carnivore distributions is critical to informing management. We conducted a mammal survey in the Ondjou Conservancy in Namibia, an 8,729 km2 understudied area in the south-west of the KAZA TCA. We analysed camera-trapping data from a 2,304 km2 grid and identified high carnivore richness (18 species) despite widespread human activity and prey depletion. Using a multi-species occupancy framework we found that carnivore occurrence increased with increasing distance from the main village and with closer proximity to the Nyae Nyae Conservancy neighbouring the KAZA TCA, which has large and diverse carnivore populations. Carnivore occurrence was higher when local prey richness was high. The Ondjou Conservancy could function as an important buffer for the larger conservation network, yet rural communities in this area require support for fostering human–wildlife coexistence. Additionally, restoring the natural prey base will be critical to ensuring the long-term viability of carnivore populations in this and other human-impacted landscapes. With many remote areas of transfrontier conservation landscapes being understudied, our findings illustrate the conservation potential of such areas within large-scale conservation networks.
Stakeholder‐driven management strategies for recovering large herbivores
In modern landscapes, the sustainable coexistence of humans and wildlife depends on involving stakeholders in the development and implementation of management strategies. This is particularly important for species like the European bison (Bison bonasus) and Eurasian moose (Alces alces), which are reoccupying regions between Germany and Poland after a prolonged absence. The return of these species generates mixed emotions, as interactions with these species are associated with both costs and benefits to people. Addressing the apparent unpreparedness in managing these trade‐offs, we implemented a digital participatory impact assessment in two steps. First, we engaged bison and moose experts to develop management scenarios and assessment criteria. Then, in a subsequent virtual workshop, stakeholders evaluated four scenarios along economic, social, and ecological dimensions. Quantitative and qualitative analyses revealed divergent perspectives and priorities, yet consensus emerged on the necessary future steps: formulating a comprehensive management strategy with guidelines and protocols for managing specific conflict scenarios, such as the incursion of large herbivores onto highways. Our approach underscores the importance of early stakeholder engagement in fostering a more equitable and sustainable management of human‐wildlife interactions. Moreover, demonstrating the feasibility of remote stakeholder involvement, our study presents a robust model for enhancing coexistence, adaptable even where in‐person meetings are challenging. Describing the Status quo of Bison and Moose populations in the German‐Polish border regions, the objective of the study, a simplified workflow through the methods. A graphical depiction of the discussed management scenarios is included, as well as summarized results and recommendations for decision makers.
Human-Wildlife Conflict at a Suburban–Wildlands Interface: Effects of Short- and Long-Distance Translocations on Red Diamond Rattlesnake (Crotalus ruber) Activity and Survival
The mitigation of human-rattlesnake conflicts often involves euthanizing or translocating the offending rattlesnake. Although translocation is generally considered more humane, especially by the general public, it may negatively impact the translocated individual and may not be effective if that individual returns to areas where the probability of human conflict is high. We used radiotelemetry to experimentally study the effects of short- (SDT) and long-distance translocation (LDT; beyond the typical home range or activity range) on adult Red Diamond Rattlesnakes (Crotalus ruber) near a residential development in Southern California. Though the results were mixed, some analyses suggested that higher numbers of SDTs were associated with larger activity areas and increased movement. For snakes undergoing LDT, the activity areas and mean daily movement distances were 1.8–4.6 times larger than those of non-LDT snakes in the year of translocation, but were similar in the following year. Cox regression models revealed that, for both LDT and non-LDT snakes, every 1 m increase in the distance moved resulted in a 1.2% decreased risk of moving back into a human-modified area and a 1.6% decreased risk of returning to the original site of conflict. We failed to detect an effect of either LDT or SDT on body mass change or survival. Our findings suggest that LDT of nuisance snakes may be a viable option for at least some rattlesnake populations or species, especially those in which individuals do not require communal overwintering sites.
