    Abstract When seeking to make land conservation decisions, should managers favor actions that will make immediate differences or those promising long-term gains? The choice depends on how individuals weight benefits and costs experienced at different future times, something temporal discount rates can be used to represent. Despite the ubiquity of inter-temporal tradeoffs in conservation decision-making, little is known about time preferences of relevant practitioners. Taking land protection decisions as an example, we use responses from experimental-choice surveys to show practitioners at environmental NGOs display high variability in how they evaluate environmental benefits and costs through time. Participants had a median discount rate of 11.9%, significantly higher than values traditionally used in environmental policy. Moreover, discount rates ranged from 74% to negative values. When asked to compare financial amounts at two future times, practitioners used discount rates that were not significantly different. When asked about an environmental attribute (protected land), they used discount rates that declined through time. We applied such rates to a spatial prioritization model to illustrate how differences we observed in discounting could influence conservation priorities today. We used species persistence in the central and southern Appalachian Mountains as our benefit stemming from protecting land. Through this illustrative application, we show that differences in how practitioners value the future change today's protection priorities, with as little as 43% overlap in counties with the highest conservation return on investment. As the conservation community re-envisions protection goals, how we weight environmental benefits and costs through time will help determine paths forward.

    Abstract Natural resource management involves balancing benefits and costs that accrue through time. How individuals and local communities weight such tradeoffs can profoundly influence how they use and conserve resources. Our goal was to understand time preferences of future benefits for goods that are relevant for developing effective conservation strategies. We surveyed >500 Fulani in Benin about their time preferences regarding financial, ecological, and agricultural goods, summarizing these in the form of discount rates. In a discrete‐time, constant annual form, our results were much higher (median: 150%) than values often discussed in literature. These discount rates declined through time; people valued the future more than would be assumed based on constant discounting. Discount rates were higher for financial goods than ecological or agricultural goods. We illustrate how our estimates of discount rates change recommendations for optimal management of forest resource harvesting in the tropics. While members of this grazing community discount future benefits at a high rate, they do so in ways that contrast with conventional economic theory and favor long‐term use of nontimber forest products.

    Abstract Research that can improve the resilience of social and natural systems to climate change has become more common. Many climate adaptation science organizations and agencies now focus on actionable science, a model that aims to have greater impacts on policy and practice than traditionally produced and distributed science. However, evaluations of research projects are needed to examine and verify the impact of climate science on adaptation and society. Better understanding the types and mechanisms of impact will allow organizations to design, fund, and facilitate more useful climate adaptation science. Many existing actionable science evaluation approaches are qualitative in nature and take considerable time and effort for funders and administrators to implement. Quantitative methods could provide a valuable option for evaluation, specifically for making comparisons across many projects. Thus, we have designed a quantitative survey instrument for measuring the use of climate adaptation science. We designed the survey using best practices and iterative input from social scientists as well as climate adaptation scientists and practitioners. We then distributed the survey to a sample of users of climate adaptation science and analyzed those responses to further refine the survey. Quantitative and qualitative results show that use of climate adaptation science may be described as either individual use or organizational use, which contrasts with popular models of use in existing evaluation literature. The survey is made available for future efforts to evaluate and improve climate adaptation science and to advance efforts to measure different kinds of use.

    Abstract To manage a recreational fishery effectively, agencies must understand who actively utilizes the fishery. Despite the popularity of stocked‐trout fishing, most studies have focused on fishing for wild trout, while few studies have attempted to describe stocked‐trout anglers. We sought to characterize stocked‐trout anglers specifically. We interviewed 3,367 anglers during their fishing trips on 17 stocked‐trout waters across Virginia. We asked anglers questions relating to their demographics, motivations, fishing and management preferences, catch and harvest that day, level of specialization, and level of satisfaction. Using a hierarchical clustering method, we identified four unique clusters of anglers: specialists, avid anglers, consumptive‐experienced anglers, and casual anglers. The clusters differed in their motivations for fishing, management and fishing preferences, and level of satisfaction. Proportions of each cluster varied across fishery types. Results from this study depict how stocked‐trout anglers differ from wild‐trout anglers. These results can help managers to adjust management strategies for various angler groups and can help managers to focus their efforts on how to recruit and retain anglers.

    Abstract We conducted a global systematic literature review of climate change adaptation in fisheries. We addressed three specific questions: (i) What are fisheries adapting to? (ii) How are fisheries adapting? and (iii) What research gaps need to be addressed? We identified, characterized and examined case studies published between 1990 and 2019 that lie at the intersection of the domains of climate change, adaptation and fisheries. We characterized the documented climate change effects in fisheries that are being adapted to multiple stressors, general climate impacts, extreme events, ocean conditions, marine system shifts, climate variability, fishery dynamics, species distribution and atmospheric warming. Three categories of adaptive responses came to light: coping mechanisms (e.g. changing fishing location, use of traditional knowledge); adaptive strategies (e.g. livelihood diversification, incorporation of technology); and management responses (e.g. adaptive management, adaptation planning). We identified key potential areas for future research, including studies on the limits and barriers for adaptation, studies using specific conceptual and methodological approaches, and studies focussing on the top‐producing countries such as China, Indonesia, Peru and Russia. This analysis gives broader insights to the fisheries industry and to climate change adaptation research to proceed in the face of new global challenges.

    Abstract Challenges facing societies around the globe as they plan for and adapt to climate change are so large that usable, research‐driven recommendations to inform management actions are urgently needed. We sought to understand factors that influence the variation of academic contribution and use of collaborative research on climate change. We surveyed researchers (n = 31), program‐leaders (n = 5), and stakeholders (n = 81) from projects supported by a federally funded network across the United States. Our results suggest that peer‐reviewed publications do not lead to use, but frequency of meetings with stakeholders significantly increased use. Overall, the factors needed for projects to have high degrees of academic contributions are distinct from those needed to be useful to stakeholders. Furthermore, leadership perceptions of use of projects were significantly different from users. Our quantitative results can inform future requests for proposals and better enable researchers using collaborative approaches to conduct science that is more often used by stakeholders.

    Abstract Hyman AA, DiCenzo VJ, Murphy BR. 2017. Muddling management: heterogeneity of blue catfish anglers. Lake Reserve Manage. 33:23–31. A world-record blue catfish was caught from Kerr Reservoir in 2011; since then, the state has experienced an influx of tournaments and trophy anglers. As a result, Virginia Department of Game and Inland Fisheries (VDGIF) has sought a holistic management approach for the blue catfish fishery. In a pilot study, we surveyed 61 catfish anglers on Kerr Reservoir, which spans the Virginia–North Carolina state line, to examine their angling habits, harvest behavior, and management preferences. Using hierarchical cluster analysis, we identified 4 distinct angler groups that, on a broad scale, parallel other specialization studies: Tournament Specialists, Consumptive Specialists, Avid Generalists, and Occasional Anglers. Results from this study depict a dualistic angler population, with many anglers seeking trophy catfish while others wish to harvest many catfish. The most-specialized anglers had a tendency to support stricter harvest limits and setline regulations, whereas the least-specialized opposed stricter regulations. With such polarized attitudes, we suggest that VDGIF and North Carolina Wildlife Resources Commission work with anglers to avoid disputes regarding gear and harvest regulations in the future. Specifically, we suggest state agencies test the use of spatial regulation of setlines (i.e., the agencies limit setline use in portions of the reservoir). Results from this research could help fisheries managers regulate trophy fisheries by understanding their anglers and in turn help to set management goals and objectives that best meet the desires of their stakeholders.

  8. Article: Dispelling Assumptions about Stocked-Trout Fisheries and Angler Satisfaction

    Abstract We investigated three assumptions about stocked-trout fisheries: (1) stocking densities (trout/km or trout/ha) correlate with angler catch rates, (2) catch rates decline with time after stocking, and (3) angler satisfaction correlates with catch rates. We interviewed 5,689 anglers on 14 put-and-take trout waters in Virginia from October 2013 to May 2014 and from October 2014 to May 2015 to assess their fishing effort for stocked trout, catch, and level of satisfaction with their fishing experience that day. Stocking density did not affect the stocked-trout catch rate on streams or lakes, and catch rates remained relatively constant from the day after stocking up to 1 month after stocking. The type of water body affected both angler effort and catch rate. We found that catch rates above thresholds (0.46 trout/angler-hour on lakes; 1.21 trout/angler-hour on streams) had minor effects on angler satisfaction, but below those threshold values, satisfaction increased greatly with increasing catch rates on both lakes and streams. Given the concerns over increasing costs to maintain stocking programs, our results suggest that agencies could reduce their stocking densities and frequencies without appreciably reducing angler satisfaction.
