Decision making-process in conservation can be very complex, having to deal with various value dimensions and potential conflicts. In fact, conflicts and competing interests between stakeholders are among the most quoted reasons for failure of projects. Ethical analysis can be helpful in this regard. In this paper we present a revision of the Ethical Matrix specifically tailored to decision-making processes in conservation. The Ethical Matrix is a conceptual tool devised to help decision-makers by supplying them with a framework of the ethically relevant aspects involved in decision-making process. It was originally developed for the ethical assessment of agri-food biotechnologies and later has been applied to other fields. The revised version we propose here has been designed for the ethical analysis of conservation priority-setting and impact. As conservation can raise many ethical relevant controversies, conceptual tools like the one presented here can be of help for conservationists, providing a map of the value demands involved. This map can be used to question the reasonableness of the value judgments, estimate the impact of different courses of actions, anticipate conflicts, and rank their severeness.

Ensuring animal welfare is a key aspect of animal management in zoological facilities and aquaria, representing a pivotal facet of their mission. Italy currently lacks a comprehensive and valuable assessment methodology for evaluating the welfare of captive animals. To address this gap, the present study aimed to identify the most important criteria that should be considered in the welfare management and assessment of animals housed in Italian zoos and aquaria. To pinpoint this issue, we engaged experts with diverse backgrounds, structuring their communication throughout an iterative process, by applying the Delphi methodology. A pilot and three Delphi rounds were administered online to 74 experts, asking them to a) validate relevant topics derived from current legislation and guidelines divided into three clusters: Care, Wellbeing, and Regulation; b) assess the relevance of these topics across taxonomic groups; c) propose and confirm indicators for each identified topic; d) suggest and refine a list of questions for animal welfare assessment. The results were three lists of questions, one for each cluster, with a total of 80 topics, 174 indicators, and 272 questions identified by the experts. The aspects included in these lists offer valuable insights into the main aspects experts consider relevant for captive animal welfare. Despite the complexity of animal welfare and the huge amount of species hosted in zoos limiting the possibility to cover this aspect with a single expert consultation, this project actively addresses the urgent need for standardization in animal welfare assessment, contributing to the ongoing development of zoological regulations in Italy. This is especially important given the current limited legislative framework, underscoring the link between animal welfare and successful ex-situ species conservation. These questions can be the basis of fine-tuned protocols to be tested in future projects aiming at animal welfare self-assessment, thus supporting authority inspection processes.

South Africa's wide range of animal facilities offers many different types of Animal-Visitor Interactions, wild animal encounters where animals and visitors come closer than in normal circumstances. The aim of this study was to provide a map of the ethically relevant aspects involved in AVIs in South Africa as a first step towards regulating these activities. A participative approach based on the ethical matrix, a tool which organizes the ethical standings of the stakeholders by three bearing ethical principles (wellbeing, autonomy, fairness), was applied. The matrix was populated through a top-down approach and refined by engaging stakeholders in a workshop and two online self-administrated surveys. The outcome is a map of the value demands concerning Animal Visitor Interactions. This map shows how the ethical acceptability of AVIs is linked to different relevant issues like animal welfare, education, biodiversity conservation, sustainability, human competency, facility mission, impact on scientific research and socio-economic outcomes. In addition, results highlighted the importance of cooperation among stakeholders and suggested that attention for animal welfare can inform decision making and inspire a multidisciplinary approach in implementing a regulatory frame for South African wildlife facilities.

Originally applied on domestic and lab animals, assisted reproduction technologies (ARTs) have also found application in conservation breeding programs, where they can make the genetic management of populations more efficient, and increase the number of individuals per generation. However, their application in wildlife conservation opens up new ethical scenarios that have not yet been fully explored. This study presents a frame for the ethical analysis of the application of ART procedures in conservation based on the Ethical Matrix (EM), and discusses a specific case study—ovum pick-up (OPU) procedures performed in the current conservation efforts for the northern white rhinoceros (Ceratotherium simum cottoni)—providing a template for the assessment of ART procedures in projects involving other endangered species.

Assisted reproductive technologies (ARTs) can make a difference in biodiversity conservation. Their application, however, can create risks and raise ethical issues that need addressing. Unfortunately, there is a lack of attention to the topic in the scientific literature and, to our knowledge, there is no tool for the ethical assessment of ARTs in the context of conservation that has been described. This paper reports the first applications of the Ethical Assessment Tool (ETHAS) to trans-rectal ovum pick-up (OPU) and in vitro fertilization (IVF) procedures used in a northern white rhinoceros (Ceratotherium simum cottoni) conservation project. The ETHAS consists of two checklists, the Ethical Evaluation Sheet and the Ethical Risk Assessment, and is specifically customized for each ART procedure. It provides an integrated, multilevel and standardized self-assessment of the procedure under scrutiny, generating an ethical acceptability ranking (totally, partially, not acceptable) and a risk rank (low, medium, high), and, hence, allows for implementing measures to address or manage issues beforehand. The application of the ETHAS to the procedures performed on the northern white rhinoceros was effective in ensuring a high standard of procedures, contributing to the acceptability and improved communication among the project’s partners. In turn, the tool itself was also refined through an iterative consultation process between experts and stakeholders.
