Conservation planning aims to optimize outcomes for select species or ecosystems by directing resources toward high-return sites. The possibility that local benefits might be increased by directing resources beyond the focal area is rarely considered. We present a case study of restoring river connectivity for migratory fish of the Great Lakes Basin by removing dams and road crossings within municipal jurisdictions versus their broader watersheds. We found that greater river connectivity could often be achieved by considering both intra-jurisdictional and extra-jurisdictional barriers. Focusing on jurisdictional barriers alone generally forfeited <20 (median = 0%) of habitat gains for those who value solely habitat...

Water temperatures are warming in lakes and streams, resulting in the loss of many native fish. Given clear passage, coldwater stream fishes can take refuge upstream when larger streams become too warm. Likewise, many Midwestern lakes “thermally stratify” resulting in warmer waters on top of deeper, cooler waters. Many of these lakes are connected to threatened streams. To date, assessments of the effects of climate change on fish have mostly ignored lakes, and focused instead on streams. Because surface waters represent a network of habitats, an integrated assessment of stream and lake temperatures under climate change is necessary for decision-making. This work can be used to inform the preservation of lake/stream...

Ecological connectivity between the Great Lakes and their tributaries is widely impaired, and many agencies and organizations are currently investing in restoring these connections to enhance target fish and wildlife populations. To assist in targeting these investments, we have been developing spatial data on the location and attributes of barriers (dams and road-stream crossings) and fish breeding habitat throughout the Great Lakes basin to analyze the optimum strategy for enhancing connectivity and restoring fish migrations. The proposed work will result in guidance for barrier restoration at scales from individual watersheds to the entire basin, refine methodologies for spatial analysis of barriers, and provide...

Control of invasive sea lamprey recruitment from tributary streams is a major management objective in the Great Lakes, and benefits from barriers that prevent access to spawning habitat. As society moves toward removal of more tributary barriers due to concerns about native migratory fishes, aging infrastructure, and vulnerability to climate-driven flooding, it is important to assess the costs of alternative options for sea lamprey control. This project is integrating cost estimates for application of a lamprey-specific pesticide into cost-benefit optimization models used to support decisions about barrier removals that maximize restoration of habitat for native species. By integrating lamprey control options...
