Understanding post-fire disturbance from nutrient monitoring

  • Funded By: National Science Foundation

Ecosystem recovery from a disturbance has fascinated ecologists for more than a century, and has gained recent attention due to the increased frequency and severity of disturbances across the globe. However, predicting how climate change will impact ecosystem succession remains limited.

This project will produce a transformative understanding of post-fire succession in thearctic tundra by monitoring elemental fluxes following an unprecedented fire in a region with one of the fastest warming rates on earth (the North Slope in Alaska).  Historical data indicate that the burn sites will undergo important successional transitions over the next 10 years.  Capturing these important changes will improve biogeochemical models of succession.  The proposed work will go towards improvement of the Multiple Element Limitation (MEL) model which predicts carbon, nitrogen, and phosphorus fluxes and stocks, and the dissemination of a long-term carbon and nutrient flux record from three sites across a burn severity gradient.
