Preview:

• Wildlife managers adapt to fragmented habitat.

• Modelled using reverse auction with a responsive budget.

• Addresses two identified shortcomings to reverse auctionmechanism.

– Low turnout of farmers can reduce cost-e↵ectiveness ofprogram (Palm-Forster et al. 2016 AJAE).

– Greater heterogeneity in seller opportunity costs reducesfiscal e�ciency of program (Messer et al. 2017 EE).

The eastern NC Red Wolf Recovery Program

A Comprehensive Review and Evaluation of the Red Wolf Recovery Program“More intensive monitoring of wolves will be required in order to respond to the

public concerns about their movement and habitat use. Alternatively, expenses

could decrease if the FWS would adopt a di↵erent management strategy that would

allow wolves to disperse throughout the restoration area. This action would likely

be tolerated only if the FWS developed a landowner incentive program that would

provide compensation for the presence of red wolves on private property within the

restoration area. Funding levels must consider the red wolf/coyote hybridization

issue that is likely to occur in any selected reintroduction site...” (WMI 2014).

Landowner incentive programs

Traditional mechanisms focus on mitigating fragmentedhabitat...

rather than adapting to its presence.

Two shortcomings:

• Unequal payouts may be more equitable when privatesentiments influence opportunity cost of enrollment.

• Mutually agreeable payouts avoid systematic overpaymentsto “green” landowners and underpayments to “brown”landowners.

Conclusions

• Adaptive and mitigative investments into species recoveryshould be jointly determined.

• Provide a framework where the costs of management infragmented areas mediates the budget for landownerincentive programs.

• Similar to Messer et al. (2017), mechanism breaks downwhen severe heterogeneity exists in private costs.

• Similar to Palm-Forster et al. (2016), low uptake rendersmitigative investments cost-ine↵ective.

• Address both of these problems by automated reallocationof budget to adaptive management options when alandowner incentive program is ailing.
