linking landscape scale conservation to regional and continental outcomes for a Migratory Species
Scientific Reports, 2020Co-Authors: Brady J Mattsson, Darius J Semmens, Laura Lopezhoffman, Wayne E Thogmartin, James A Dubovsky, J H Devries, Jonathan J DerbridgeAbstract:Land-use intensification on arable land is expanding and posing a threat to biodiversity and ecosystem services worldwide. We develop methods to link funding for avian breeding habitat conservation and management at landscape scales to equilibrium abundance of a Migratory Species at the continental scale. We apply this novel approach to a harvested bird valued by birders and hunters in North America, the northern pintail duck (Anas acuta), a Species well below its population goal. Based on empirical observations from 2007–2016, habitat conservation investments for waterfowl cost $313 M and affected <2% of the pintail’s primary breeding area in the Prairie Pothole Region of Canada. Realistic scenarios for harvest and habitat conservation costing an estimated $588 M (2016 USD) led to predicted pintail population sizes <3 M when assuming average parameter values. Accounting for parameter uncertainty, converting 70–100% of these croplands to idle grassland (cost: $35.7B–50B) is required to achieve the continental population goal of 4 M individuals under the current harvest policy. Using our work as a starting point, we propose continued development of modeling approaches that link conservation funding, habitat delivery, and population response to better integrate conservation efforts and harvest management of economically important Migratory Species.

multi country willingness to pay for transborder Migratory Species conservation a case study of northern pintails
Ecological Economics, 2019Co-Authors: Michelle Haefele, Darius J Semmens, Robert Merideth, Kenneth J Bagstad, John B Loomis, Brady J Mattsson, James A Dubovsky, Aaron M Lien, Taken Huang, Wayne E ThogmartinAbstract:Abstract Using contingent valuation, we estimated willingness to pay (WTP) in Canada, Mexico, and the United States to protect habitat for Northern Pintails (hereafter pintails), a Migratory waterfowl Species that provides benefits to and requires habitat in the three countries. Our study contributes to research on spatial subsidies by measuring the value of Migratory Species habitat. While WTP to protect pintail habitat is highest in the household's own country, there also is substantial WTP to protect pintail habitat in the other two countries. Canadian households' annual WTP is US$12 (all dollar values are in 2016 US dollars) to stabilize the pintail population in Canada, US$4 in Mexico, and US$5 in the U.S. Mexican households would pay US$8 in Mexico, US$5 in the U.S., and US$5 in Canada. U.S. households would pay US$28 in the U.S., US$18 in Canada, and US$16 in Mexico. WTP is statistically significantly higher in all three countries to increase the pintail population. WTP as a percentage of household income is statistically significantly higher for respondents in Mexico. WTP is logically related to explanatory variables such as respondent income, interest in hunting waterfowl, and financial support of wildlife conservation organizations. This study has important implications for conducting economic analyses of habitat issues of transboundary Migratory Species' conservation and to more effectively and equitably achieve conservation goals.

ecosystem service flows from a Migratory Species spatial subsidies of the northern pintail
AMBIO: A Journal of the Human Environment, 2019Co-Authors: Kenneth J Bagstad, Darius J Semmens, James E Diffendorfer, Wayne E Thogmartin, Ruscena Wiederholt, John B Loomis, Brady J Mattsson, James A Dubovsky, Joanna A Bieri, Christine SampleAbstract:Migratory Species provide important benefits to society, but their cross-border conservation poses serious challenges. By quantifying the economic value of ecosystem services (ESs) provided across a Species’ range and ecological data on a Species’ habitat dependence, we estimate spatial subsidies—how different regions support ESs provided by a Species across its range. We illustrate this method for Migratory northern pintail ducks in North America. Pintails support over $101 million USD annually in recreational hunting and viewing and subsistence hunting in the U.S. and Canada. Pintail breeding regions provide nearly $30 million in subsidies to wintering regions, with the “Prairie Pothole” region supplying over $24 million in annual benefits to other regions. This information can be used to inform conservation funding allocation among Migratory regions and nations on which the pintail depends. We thus illustrate a transferrable method to quantify Migratory Species-derived ESs and provide information to aid in their transboundary conservation.

Willingness to Pay for Conservation of Transborder Migratory Species: A Case Study of the Mexican Free-Tailed Bat in the United States and Mexico
Environmental Management, 2018Co-Authors: Michelle Haefele, Darius J Semmens, Wayne E Thogmartin, Robert Merideth, Ruscena Wiederholt, John B Loomis, Taken Huang, Aaron Lien, James Dubovsky, Gary MccrackenAbstract:We estimated U.S. and Mexican citizens’ willingness to pay (WTP) for protecting habitat for a transborder Migratory Species, the Mexican free-tailed bat ( Tadarida brasiliensis mexicana ), using the contingent valuation method. Few contingent valuation surveys have evaluated whether households in one country would pay to protect habitat in another country. This study addresses that gap. In our study, Mexican respondents were asked about their WTP for conservation of Mexican free-tailed bat habitat in Mexico and in the United States. Similarly, U.S. respondents were asked about their WTP for conservation in the United States and in Mexico. U.S. households would pay $30 annually to protect habitat in the United States and $24 annually to protect habitat in Mexico. Mexican households would pay $8 annually to protect habitat in Mexico and $5 annually to protect habitat in the United States. In both countries, these WTP amounts rose significantly for increasing the size of the bat population rather than simply stabilizing the current bat population. The ratio of Mexican household WTP relative to U.S. household WTP is nearly identical to that of Mexican household income relative to U.S. household income. This suggests that the perceived economic benefits received from the bats is similar in Mexico and the United States, and that scaling WTP by relative income in international benefit transfer may be plausible.

quantifying ecosystem service flows at multiple scales across the range of a long distance Migratory Species
Ecosystem services, 2018Co-Authors: Darius J Semmens, James E Diffendorfer, Kenneth J Bagstad, Ruscena Wiederholt, Karen S Oberhauser, Leslie Ries, Brice X Semmens, Joshua H Goldstein, John B LoomisAbstract:Abstract Migratory Species provide ecosystem goods and services throughout their annual cycles, often over long distances. Designing effective conservation solutions for Migratory Species requires knowledge of both Species ecology and the socioeconomic context of their migrations. We present a framework built around the concept that Migratory Species act as carriers, delivering benefit flows to people throughout their annual cycle that are supported by the network of ecosystems upon which the Species depend. We apply this framework to the monarch butterfly (Danaus plexippus) migration of eastern North America by calculating their spatial subsidies. Spatial subsidies are the net ecosystem service flows throughout a Species’ range and a quantitative measure of the spatial mismatch between the locations where people receive most benefits and the locations of habitats that most support the Species. Results indicate cultural benefits provided by monarchs in the U.S. and Canada are subsidized by migration and overwintering habitat in Mexico. At a finer scale, throughout the monarch range, habitat in rural landscapes subsidizes urban residents. Understanding the spatial distribution of benefits derived from and ecological support provided to monarchs and other Migratory Species offers a promising means of understanding the costs and benefits associated with conservation across jurisdictional borders.

recreation economics to inform Migratory Species conservation case study of the northern pintail
Journal of Environmental Management, 2018Co-Authors: Brady J Mattsson, Darius J Semmens, James E Diffendorfer, Wayne E Thogmartin, Kenneth J Bagstad, Ruscena Wiederholt, Joshua H Goldstein, John B Loomis, James A Dubovsky, Laura LopezhoffmanAbstract:Quantification of the economic value provided by Migratory Species can aid in targeting management efforts and funding to locations yielding the greatest benefits to society and Species conservation. Here we illustrate a key step in this process by estimating hunting and birding values of the northern pintail (Anas acuta) within primary breeding and wintering habitats used during the Species' annual Migratory cycle in North America. We used published information on user expenditures and net economic values (consumer surplus) for recreational viewing and hunting to determine the economic value of pintail-based recreation in three primary breeding areas and two primary wintering areas. Summed expenditures and consumer surplus for northern pintail viewing were annually valued at $70M, and annual sport hunting totaled $31M (2014 USD). Expenditures for viewing ($42M) were more than twice as high than those for hunting ($18M). Estimates of consumer surplus, defined as the amount consumers are willing to pay above their current expenditures, were $15M greater for viewing ($28M) than for hunting ($13M). We discovered substantial annual consumer surplus ($41M) available for pintail conservation from birders and hunters. We also found spatial differences in economic value among the primary regions used by pintails, with viewing generally valued more in breeding regions than in wintering regions and the reverse being true for hunting. The economic value of pintail-based recreation in the Western wintering region ($26M) exceeded that in any other region by at least a factor of three. Our approach of developing regionally explicit economic values can be extended to other taxonomic groups, and is particularly suitable for Migratory game birds because of the availability of large amounts of data. When combined with habitat-linked population models, regionally explicit values could inform development of more effective conservation finance and policy mechanisms to enhance environmental management and societal benefits across the geographically dispersed areas used by Migratory Species.

ecosystem services from transborder Migratory Species implications for conservation governance
Annual Review of Environment and Resources, 2017Co-Authors: Laura Lopezhoffman, Darius J Semmens, Charles C Chester, Wayne E Thogmartin, Sofia M Rodriguezmcgoffin, Robert Merideth, Jay E DiffendorferAbstract:This article discusses the conservation challenges of volant Migratory transborder Species and conservation governance primarily in North America. Many Migratory Species provide ecosystem service benefits to society. For example, insectivorous bats prey on crop pests and reduce the need for pesticides; birds and insects pollinate food plants; and birds afford recreational opportunities to hunters and birdwatchers. Migration is driven by the seasonal availability of resources; as resources in one area become seasonally scarce, individuals move to locations where resources have become seasonally abundant. The separation of the annual lifecycle means that Species management and governance is often fractured across international borders. Because Migratory Species depend on habitat in different locations, their ability to provide ecosystem services in one area depends on the spatial subsidies, or support, provided by habitat and ecological processes in other areas. This creates telecouplings, or interconnectio...

accounting for the ecosystem services of Migratory Species quantifying migration support and spatial subsidies
Ecological Economics, 2011Co-Authors: Darius J Semmens, James E Diffendorfer, Laura Lopezhoffman, Carl D ShapiroAbstract:Migratory Species support ecosystem process and function in multiple areas, establishing ecological linkages between their different habitats. As they travel, Migratory Species also provide ecosystem services to people in many different locations. Previous research suggests there may be spatial mismatches between locations where humans use services and the ecosystems that produce them. This occurs with Migratory Species, between the areas that most support the Species' population viability – and hence their long-term ability to provide services – and the locations where Species provide the most ecosystem services. This paper presents a conceptual framework for estimating how much a particular location supports the provision of ecosystem services in other locations, and for estimating the extent to which local benefits are dependent upon other locations. We also describe a method for estimating the net payment, or subsidy, owed by or to a location that balances benefits received and support provided by locations throughout the Migratory range of multiple Species. The ability to quantify these spatial subsidies could provide a foundation for the establishment of markets that incentivize cross-jurisdictional cooperative management of Migratory Species. It could also provide a mechanism for resolving conflicts over the sustainable and equitable allocation of exploited Migratory Species.

Here we illustrate a key step in this process by estimating hunting and birding values of the northern pintail (Anas acuta) within primary breeding and wintering habitats used during the Species' annual Migratory cycle in North America. We used published information on user expenditures and net economic values (consumer surplus) for recreational viewing and hunting to determine the economic value of pintail-based recreation in three primary breeding areas and two primary wintering areas. Summed expenditures and consumer surplus for northern pintail viewing were annually valued at $70M, and annual sport hunting totaled $31M (2014 USD). Expenditures for viewing ($42M) were more than twice as high than those for hunting ($18M). Estimates of consumer surplus, defined as the amount consumers are willing to pay above their current expenditures, were $15M greater for viewing ($28M) than for hunting ($13M). We discovered substantial annual consumer surplus ($41M) available for pintail conservation from birders and hunters. We also found spatial differences in economic value among the primary regions used by pintails, with viewing generally valued more in breeding regions than in wintering regions and the reverse being true for hunting. The economic value of pintail-based recreation in the Western wintering region ($26M) exceeded that in any other region by at least a factor of three. Our approach of developing regionally explicit economic values can be extended to other taxonomic groups, and is particularly suitable for Migratory game birds because of the availability of large amounts of data. When combined with habitat-linked population models, regionally explicit values could inform development of more effective conservation finance and policy mechanisms to enhance environmental management and societal benefits across the geographically dispersed areas used by Migratory Species.
