Natural resource managers are confronted with the pressing challenge to develop conservation plans that address complex ecological and societal needs against the backdrop of a rapidly changing climate. Climate change vulnerability assessments (CCVAs) provide valuable information that helps guide management and conservation actions in this regard. An essential component to CCVAs is...

Many Midwestern lakes are experiencing warming water temperatures as a result of climate change. In general, this change is causing coldwater fish species such as cisco and coolwater species such as walleye to decline. Meanwhile, warmer water species such as largemouth and smallmouth bass are increasing as temperatures warm. However, some fish populations are more vulnerable to these...

Overview Invasive species and climate change represent two of the five major global change threats to ecosystems. An emerging initiative of the Northeast Climate Science Center aims to develop management-relevant research to improve invasive species management in the face of climate change. Through working groups, information sharing and targeted research, this project addresses the

The Colorado River and its major tributaries provide a crucial water supply for more than 40 million people in the American Southwest and in California. This water supply is primarily used in irrigated agriculture but also provides essential drinking water to many large metropolitan areas. Hydropower is also produced at many of the large dams on the river. River flows have declined...

Salmon that spawn and rear in Southeast Alaska watersheds are critically important to the region’s economic vitality and cultural identity. An estimated 90% of rural households in Southeast Alaska use salmon. Environmental changes that compromise the ability of these streams to support salmon could have dramatic consequences for the region. In particular, there is concern that climate...

Every 10 years, state fish and wildlife management agencies must comprehensively review, and if necessary revise, their State Wildlife Action Plans (SWAPs). These are important planning documents that serve as blueprints for conserving fish, wildlife, and their habitat, and for preventing species listings in each state. These plans focus on species that have been identified as being of...

The Food and Agriculture Organization of the United Nations (FAO) documents the status and trends of marine fish stocks that represent approximately 80% of global marine catch. These stocks are routinely monitored, and the FAO assessment describes the extent of exploitation against different reference points - such as underfished, sustainable fished, or overfished. Although inland...

Fisheries in the glacial lakes region of the upper Midwest are culturally, economically, and recreationally beneficial. Walleye, for instance, represent an important subsistence food source for some Wisconsin tribal nations and are also popular among recreational anglers. However, predicted ecological changes to these aquatic communities, such as an increase in invasive fish species, a...

Changing climate conditions such as increasing droughts, floods, and wildfires, hotter temperatures, declining snowpacks, and changes in the timing of seasonal events are already having an impact on wildlife and their habitats. In order to make forward-looking management decisions that consider ongoing and future projected changes in climate, managers require access to climate...
