A practical conservation tool to combine diverse types of evidence for transparent evidence-based decision-making

Making the reasoning and evidence behind conservation decisions clear and transparent is a key challenge for the conservation community. Similarly, combining evidence from diverse sources (e.g., scientific vs non-scientific information) into decision-making is also difficult. Our group of conservation researchers and practitioners has co-produced an intuitive tool and template (Evidence-to-Decision (E2D) tool: www.evidence2decisiontool.com) to guide practitioners through a structured process to transparently document and report the evidence and reasoning behind decisions. The tool has three major steps: 1. Define the Decision Context; 2. Gather Evidence; and 3. Make an Evidence-Based Decision. In each step, practitioners enter information (e.g., from the scientific literature, practitioner knowledge and experience, and costs) to inform their decision-making and document their reasoning. The tool packages this information into a customised downloadable report (or is documented if using the offline template), which we hope can stimulate the exchange of information on decisions within and between organisations. By enabling practitioners to revisit how and why past decisions were made, and integrate diverse forms of evidence, we believe our open-access tool’s template can help increase the transparency and quality of decision-making in conservation.

Can Deliberative Democracy Favor a Flourishing Relationship Between Humans and Carnivores?

There is considerable interest in improving participatory governance in decision-making processes for the conservation of biodiversity and management of conflicts between humans and wildlife. Among the various modes of participatory governance, deliberative democracy has received virtually no attention for decisions focused on conserving biodiversity. This is surprising given that deliberative democracy is an important branch of democratic theory and is associated with decision-making processes that have been successfully applied to a wide range of complicated decisions across diverse cultural settings. Moreover, deliberative democracy has several distinctive properties that would seem to make it well-suited for many conservation decisions. First, deliberative democracy is better-designed than other processes to handle cases where the object of conservation appears to be insufficiently valued by those who have the most detrimental impacts on its conservation. Second, deliberative democracy engenders a rich kind of representation and impartiality that is nearly impossible to achieve with participatory governance focused on managing conflicts among hyper-engaged stakeholders. Here, we review the principles of deliberative democracy, outline procedures for its application to carnivore conservation, and consider its likelihood to favor carnivore conservation.

From the cloud to the ground: converting satellite data into conservation decisions

An estimated 65% of the world’s land and more than 80% of Earth’s biodiversity are under indigenous or local community customary ownership, care, and use. Recent developments in remote sensing, geographic information systems (GIS), mobile, and cloud computing provide the opportunity to systematically and cost-effectively monitor land-cover and land-use changes and threats at multiple scales. It is now possible, via satellite observations, to obtain a synoptic view of ecosystems at spatial and temporal resolutions that are more detailed, locally relevant, and consistent from village to global scales. However, to make geospatial data and technologies work for conservation, we still need to understand how data turn into actionable information and conservation decisions. This chapter uses Open Standards for the Practice of Conservation as a framework to discuss insights from 18 years of using geospatial technologies with the local communities, village and district governments, and other partners to monitor chimpanzee habitats and threats and inform chimpanzee conservation strategies and actions in Tanzania. It focuses on how Earth Observation data and associated technologies enabled and benefitted from the creation of research-implementation spaces in which stakeholders were able to collaborate and interact with geospatial data and results in a diversity of ways. This enabled development of geospatial applications and solutions ‘with’ and not ‘for’ local stakeholders, resulting in expansion of new protected areas managed by village and districts governments and restoration of habitats in some degraded village forest reserves.

The Conservation of Renewable Resources

Chapter 4 further develops the theory of the conservation of living systems. Natural resource management problems are analyzed using optimal control methods. Natural resources are the state variables of the problem and management instruments are control variables. Management might include harvest, culling, restocking, reseeding, and replanting, or interventions affecting, for example, the fire regime, hydrological flows, the structure of habitats, the functioning of the system, and the ecosystem processes involved. The chapter considers three types of systems: aquatic systems, forest systems, and rangelands. It shows how the methods developed to model conversion/conservation decisions in all cases embed the Hotelling arbitrage condition. It shows how the level of conservation in each type of system is impacted by access rules, and the array of benefits obtained from the system.

Towards the Optimization of eDNA/eRNA Sampling Technologies for Marine Biosecurity Surveillance

The field of eDNA is growing exponentially in response to the need for detecting rare and invasive species for management and conservation decisions. Developing technologies and standard protocols within the biosecurity sector must address myriad challenges associated with marine environments, including salinity, temperature, advective and deposition processes, hydrochemistry and pH, and contaminating agents. These approaches must also provide a robust framework that meets the need for biosecurity management decisions regarding threats to human health, environmental resources, and economic interests, especially in areas with limited clean-laboratory resources and experienced personnel. This contribution aims to facilitate dialogue and innovation within this sector by reviewing current approaches for sample collection, post-sampling capture and concentration of eDNA, preservation, and extraction, all through a biosecurity monitoring lens.

Punctuated ecological equilibrium in mammal communities over evolutionary time scales

The study of deep-time ecological dynamics has the ability to inform conservation decisions by anticipating the behavior of ecosystems millions of years into the future. Using network analysis and an exceptional fossil dataset spanning the past 21 million years, we show that mammalian ecological assemblages undergo long periods of functional stasis, notwithstanding high taxonomic volatility due to dispersal, speciation, and extinction. Higher functional richness and diversity promoted the persistence of functional faunas despite species extinction risk being indistinguishable among these different faunas. These findings, and the large mismatch between functional and taxonomic successions, indicate that although safeguarding functional diversity may or may not minimize species losses, it would certainly enhance the persistence of ecosystem functioning in the face of future disturbances.
