Special Issue Information

Dear Colleagues,

The welfare of wild animals is a growing public concern, often leading to polarized views. Those driven by conservation perspectives prioritize ecological processes and populations, while those focused on individual animals tend to approach natural processes, such as premature death or predation, as welfare issues to be addressed. Some believe intervention is necessary only when humans cause harm, while others advocate for minimizing suffering whenever possible, regardless of anthropogenic interference. In turn, conservation policies vary greatly between jurisdictions, reflecting cultural and economic priorities, ethical values, and legal frameworks. These conflicting views create challenges in finding One Health/One Welfare approaches that can balance human interests, ecological sustainability, and animal welfare.

This conundrum raises challenging questions: Should all wild animals be considered equally? And if not, where should we draw a line of moral concern? Can we improve the welfare of some wild animals without harming other related animals? How can regulations shape policy and action to reconcile wild animal welfare against the needs of people?

Robust scientific information is crucial for evidence-based decisions and bridging the gaps that fuel polarization. In this Special Issue, we invite submissions of original research on wild animal welfare science, ethics, and law. We also welcome reviews, reflective papers on ethical views or regulatory frameworks, and social science research focusing on captive and free-ranging wildlife, recognizing the importance of diverse approaches in advancing wild animal welfare.

Killing Neck Snares Are Inhumane and Non-Selective, and Should Be Banned

In North America, where fur trapping remains an active practice, killing neck snares continue to be used for capturing canids, particularly red fox (Vulpes vulpes), coyote (Canis latrans), and gray wolf (Canis lupus). However, over the last 50 years, scientific studies have consistently demonstrated that killing neck snares are inhumane—meaning that snared animals do not lose consciousness within five minutes and may remain alive for hours—and non-selective, often capturing a wide range of non-target wild and domestic animals. This non-selectivity can contribute to the local extirpation of certain species. The continued use of killing neck snares reflects a disregard for the welfare of wild mammals and poses risks to the sustainability of their populations. This persistence appears to be driven by misinformation, widespread myths, and inadequately implemented international trapping standards. These issues lead to critical questions about what must be performed to prohibit the use of these devices. Full article

The recent birth of genetically modified canids phenotypically resembling the extinct dire wolf (Aenocyon dirus) was hailed as a landmark in synthetic biology. Using genome editing and cloning, the biotech company Colossal Biosciences created three such animals from gray wolf cells, describing the project as an effort in “functional de-extinction”. This case raises significant questions regarding animal welfare, moral justification, and regulatory governance. We used the five domains model framework to assess the welfare risks for the engineered animals, the surrogate mothers used in reproduction, and other animals potentially affected by future reintroduction or escape scenarios. Ethical implications are examined through utilitarian, deontological, virtue, relational, and environmental ethics. Our analysis suggests that the project suffers from ontological ambiguity: it is unclear whether the animals created are resurrected species, hybrids, or novel organisms. While the current welfare of the engineered animals may be manageable, their long-term well-being, particularly under rewilding scenarios, is likely to be compromised. The moral arguments for reviving long-extinct species are weak, particularly in cases where extinction was not anthropogenic. Legally, the current EU frameworks lack the clarity and scope to classify, regulate, or protect genetically engineered extinct animals. We recommend that functional de-extinction involving sentient beings be approached with caution, supported by revised welfare tools and regulatory mechanisms. Full article
