How is climate change affecting tribal lifeways in Minnesota?
Climate change poses a significant threat to the sustainability of numerous natural resources vital to the well-being and cultural practices of tribal communities within our shared region. Rising temperatures, more frequent and intense extreme weather events, and heightened disease pressures are already impacting flora and fauna essential to their livelihoods.
Culturally important species
Culturally important species are threatened by rising temperatures and changing precipitation patterns. For example, cold-water fish like walleye face habitat loss1, and bison body size is expected to shrink due to warmer temperatures and droughts2. Rising temperatures threaten Minnesota’s moose populations through the spread of ticks, diseases, and heat stress3,4.
Seasonal harvesting activities
Seasonal harvesting activities may shift or decline due to rising temperatures. Warming winters have altered the timing and length of sugarbush season5. Climate models suggest that in the coming decades, rising temperatures will push the range of the sugar maple in Minnesota northward, and reduce the sugar content in maple sap6,7. Wild rice harvests may decline because of increasing spring precipitation and reduced snowfall in the winter1.
Native pollinators
Native pollinators face rising temperatures and precipitation shifts that could jeopardize food security initiatives and culturally relevant plants and animals. The out-competition of native pollinators and a shifting climate may also lead to increased crop pests and crop disease migration, further threatening crop-pollinator dynamics and overall habitat health8,9.
