Rivercane (Arundinaria gigantea), an ecocultural keystone plant, has shaped both riverine ecosystems and Indigenous lifestyles in the Southeastern USA for centuries. Rivercane provides various ecoservices through streambank stabilization, flood and nutrient attenuation, and providing habitat for native fauna. In precolonial times, Indigenous tribes actively maintained rivercane across the landscape for use in building, crafting, and hunting. This native bamboo species once dominated the majority of southeastern floodplains, but repression of Indigenous cultivation resulted in 98% reduction of rivercane’s historic coverage. The decline of rivercane has resulted in degraded watersheds and a shortage of cultural resources for tribes. Despite this loss and subsequent gaps in knowledge on rivercane, rivercane is sought for riparian restoration as well as Indigenous cultural practices. Western science must incorporate Indigenous knowledge for cultivation of rivercane ecosystems to be successful. This coproduced project seeks to assess the effects of culturally informed management on the sustainable growth of rivercane, as well as how extreme flooding impacts the resilience of rivercane. We established plots in a rivercane stand in Yancey County, North Carolina in 2023, randomly assigned to treatments: artisanal harvest, cleared, and control. We measured changes in rivercane growth and environmental conditions to determine effects of treatment type as well as of post-storm flood impact. Trends in rivercane growth data show an association between density and stem width, indicating a possible grouping effect in which large stems grow closer together in areas providing better conditions, such as increased light availability in artisanal harvest treatments. Major floods deposited significant sedimentation which attenuated from the edge to interior of the rivercane stand, demonstrating the potential of rivercane to resist storm damage. This study integrates both ecological and cultural perspectives to fill gaps in our understanding of rivercane, improving conservation efforts crucial to protecting the resilience of riparian systems in the face of land use and climate changes.
