Public opinion on protecting iconic species depends on individual wellbeing: perceptions about orangutan conservation in Indonesia and Malaysia

Public opinion has the potential to shape conservation policy-making and implementation. At a local scale, it is argued that human wellbeing is important for conservation success. However, little research has explored how social factors like wellbeing shape public opinion at cross-national scales. Here, we focus on orangutan conservation, where an iconic species near extinction exists amidst complex social issues. We surveyed 2073 Indonesian and Malaysian residents and assessed three indicators of conservation support: policy support, willingness to act for the environment, and willingness to act for orangutans. We then examined how diverse indicators of wellbeing shaped support for orangutan conservation. Our results show that diverse indicators of wellbeing are related to public opinions supportive of conservation in Indonesian and Malaysian citizens. Consistent with our hypotheses, both physical (having basic needs met) and psychological (being free from worry, feeling safe, a sense of agency) wellbeing were positively associated with all three indicators of conservation support. Contrary to common assumptions, not all wellbeing indicators were related to conservation support; we found no evidence that subjective health was positively associated with conservation support. Overall, these findings indicate that social factors such as wellbeing might have an important influence on public opinion about conservation issues, and subsequently, environmental policy-making. Our findings highlight the complexity of the relationship between wellbeing and public opinion, alongside the need to consider multi-dimensional aspects of wellbeing across diverse social and geographic settings

Killing of orangutans in Kalimantan: community perspectives on incidence and drivers

Despite decades of conservation management, many orangutan populations are on the brink of extinction. This is primarily due to habitat loss and direct killings. A study from 2008/2009 suggested that killing was impacting orangutan populations at a rate sufficient to cause local extinctions. As an illegal and taboo behavior that is difficult to measure, killing has been severely understudied since. We conducted 431 interviews in 79 villages across Kalimantan in 2020/2021. Ours is the first quantitative field study in more than 10 years to assess the state of killing of orangutans. We aimed to: (1) assess the current state of killing of orangutans in Kalimantan and compare this to the previous study; (2) determine whether conservation projects are affecting killing; and (3) explore drivers of killing. We examined killing of orangutans across villages with forest conservation projects, orangutan conservation projects, and no conservation projects. We assessed the existence of killing and used scenarios to examine perceived norms about illegal behavior relating to orangutans. We then used matching techniques to assess whether projects have any impact on these indicators. Overall, our findings suggest that killing has occurred in recent times, and our data does not indicate a clear attenuation of the behavior. As such, we argue that killing may still present a substantial threat to Bornean orangutan populations. We also found no statistically significant evidence that conservation projects are reducing killing. Conservation project managers could seek to understand the drivers of killing, and to invest in interventions that address these drivers. Research suggests that current allocation of conservation funding has been ineffective at abating orangutan population decline. We argue that a key part of improving Bornean orangutan conservation practice involves directly addressing killing of orangutans and the underlying drivers of killing

Disease risk and conservation implications of orangutan translocations

Critically Endangered orangutans are translocated in several situations: reintroduced into historic range where no wild populations exist, released to reinforce existing wild populations, and wild-to-wild translocated to remove individuals from potentially risky situations. Translocated orangutans exposed to human diseases, including Coronavirus Disease 2019 (COVID-19), pose risks to wild and previously released conspecifics. Wildlife disease risk experts recommended halting great ape translocations during the COVID-19 pandemic to minimize risk of disease transmission to wild populations. We collected data on orangutan releases and associated disease risk management in Indonesia during the COVID-19 pandemic, and developed a problem description for orangutan disease and conservation risks. We identified that at least 15 rehabilitated ex-captive and 27 wild captured orangutans were released during the study period. Identified disease risks included several wild-to-wild translocated orangutans in direct contact or proximity to humans without protective equipment, and formerly captive rehabilitated orangutans that have had long periods of contact and potential exposure to human diseases. While translocation practitioners typically employ mitigation measures to decrease disease transmission likelihood, these measures cannot eliminate all risk, and are not consistently applied. COVID-19 and other diseases of human origin can be transmitted to orangutans, which could have catastrophic impacts on wild orangutans, other susceptible fauna, and humans should disease transmission occur. We recommend stakeholders conduct a Disease Risk Analysis for orangutan translocation, and improve pathogen surveillance and mitigation measures to decrease the likelihood of potential outbreaks. We also suggest refocusing conservation efforts on alternatives to wild-to-wild translocation including mitigating human-orangutan interactions, enforcing laws and protecting orangutan habitats to conserve orangutans in situ

Restoring the orangutan in a whole- or half-earth context

Various global-scale proposals exist to reduce the loss of biological diversity. These include the Half-Earth and Whole-Earth visions that respectively seek to set aside half the planet for wildlife conservation or to diversify conservation practices fundamentally and change the economic systems that determine environmental harm. Here we assess these visions in the specific context of Bornean orangutans Pongo pygmaeus and their conservation. Using an expert-led process we explored three scenarios over a 10-year time frame: continuation of Current Conditions, a Half-Earth approach and a Whole-Earth approach. In addition, we examined a 100-year population recovery scenario assuming 0% offtake of Bornean orangutans. Current Conditions were predicted to result in a population c. 73% of its current size by 2032. Half-Earth was judged comparatively easy to achieve and predicted to result in an orangutan population of c. 87% of its current size by 2032. Whole-Earth was anticipated to lead to greater forest loss and ape killing, resulting in a prediction of c. 44% of the current orangutan population for 2032. Finally, under the recovery scenario, populations could be c. 148% of their current size by 2122. Although we acknowledge uncertainties in all of these predictions, we conclude that the Half-Earth and Whole-Earth visions operate along different timelines, with the implementation of Whole-Earth requiring too much time to benefit orangutans. None of the theorized proposals provided a complete solution, so drawing elements from each will be required. We provide recommendations for equitable outcomes

Pathways between contrasting ecotourism experiences and conservation engagement

It is commonly believed that nature experiences lead to increased concern for nature, and ultimately, the expression of conservation behaviours. Captive and non-captive ecotourism experiences with charismatic megafauna have been associated with conservation support. However, there is little research examining experiences with non-mammalian wildlife, or familiar species in domestic settings. We conducted interviews (N = 427) at two ecotourism destinations in Australia (a conservation-focused zoological park and a rainforest national park), to determine\ua0whether these experiences are associated with conservation engagement and if so, the pathways through which these\ua0might operate. Interviews identified the elements of experience (site, duration, animal encounter, educational shows, and interpretive signs), the subjective aspects of their experience (positive and negative emotions, learning, connection, reflection), and engagement in conservation (environmental intentions, policy support and signing a conservation-focused pledge). Regression analyses examined the relationship between elements of experience and conservation engagement, while controlling for demographics and nature-relatedness. Participating in non-captive bird feeding at the rainforest site was associated with greater support for conservation policies, whereas visiting the zoological park was associated with greater intention to seek and share conservation information. Mediation analysis demonstrated that both of these relationships were mediated by feeling upset about environmental problems, indicating a role for negative emotions alongside ecotourism experiences in prompting conservation engagement. No element of the experience was associated with signing the pledge, highlighting the challenges of eliciting behaviour change. Overall, these findings suggest that different types of ecotourism experiences may generate different types of conservation engagement, and that that associated negative emotions about the plight of species can foster stronger engagement in conservation issues

The potential for applying 'Nonviolent Communication' in conservation science

The role of a conservation scientist has never been more challenging. Amidst the rapid degradation occurring across Earth's natural ecosystems and the loss of biodiversity and ecosystem services, conservation scientists must learn new and effective ways to build trust and engage with the wider community. Here, we discuss the potential utility of a particular communication technique, Nonviolent Communication (also known as Compassionate Communication or Collaborative Communication), in conservation science. Nonviolent Communication is a structured form of communication, developed in the 1960s by Dr. Marshall Rosenberg, that seeks to foster interpersonal understanding and connection through communication of judgment-free observations, recognition of people's feelings, needs and values, and requests for specific actions to meet those needs. It has delivered positive outcomes in diverse fields such as prisoner reform, health science, and social work, and holds great promise for conservation applications. While there is no single communication strategy that resonates with all people, we argue that Nonviolent Communication could be used by conservation scientists and practitioners when communicating with colleagues, politicians, and the general public about important and sometimes contentious environmental issues.</p

Effectiveness of 20 years of conservation investments in protecting orangutans

Conservation strategies are rarely systematically evaluated, which reduces transparency, hinders the cost-effective deployment of resources, and hides what works best in different contexts. Using data on the iconic and critically endangered orangutan (Pongo spp.), we developed a novel spatiotemporal framework for evaluating conservation investments. We show that around USD 1 billion was invested between 2000 and 2019 into orangutan conservation by governments, non-governmental organizations, companies and communities. Broken down by allocation to different conservation strategies, we find that habitat protection, patrolling and public outreach had the greatest return-on-investment for maintaining orangutan populations. Given variability in threats, land-use opportunity costs, and baseline remunerations in different regions, there were differential benefits-per-dollar invested across conservation activities and regions. We show that, while challenging from a data and analysis perspective, it is possible to fully understand the relationships between conservation investments and outcomes, and the external factors that influence these outcomes. Such analyses can provide improved guidance towards more effective biodiversity conservation. Insights into the spatiotemporal interplays between the costs and benefits driving effectiveness can inform decisions about the most suitable orangutan conservation strategies for halting population declines. While our study focuses on the three extant orangutan species of Sumatra and Borneo, our findings have broad application for evidence-based conservation science and practice worldwide
