Globally, riparian and wetland ecosystems provide critical goods and services. For example, these systems are often biodiversity and biogeochemical hotspots and may serve to buffer upland and coastal communities from extreme climate events. These systems provide unique challenges to researchers and managers since they are especially vulnerable to degradation and loss due to anthropogenic disturbances and impacts of climate change. These challenges include, but are not limited to, changes in hydrology and precipitation affecting flow dynamics in riparian zones, altered water and nutrient cycling within watersheds, changes in fire regimes, loss of biodiversity due to invasions and habitat loss due to urbanization and sea level rise. Wetlands have been disappearing at alarming rates in the US over the past 200 years. Less than ten percent of historic coastal wetlands remain in California, and Louisiana loses an estimated 75 square kilometers annually. The loss and degradation of these habitats impairs ecosystem services that support human activities in coastal and interior locations. This inspire session will gather ecologists from various wetland and riparian systems throughout the US to discuss organism- to landscape-level changes that result from shifts in precipitation regimes, non-native plant invasions, pollution and runoff, and changing climate. Current research is reaching across disciplines and continued collaborative efforts connecting information from physiological limits of organisms, population demography and landscape level assessments of habitat loss/change will help guide our understanding of how the function and resilience of riparian and wetland ecosystems will change in the future.
