The Science Issue and Relevance
Methodology for Addressing the Issue
The objectives of this project are to: (1) characterize potential carbon sequestration in representative vegetation communities via gaseous and water based carbon fluxes and by estimating carbon storage in biomass and soil pools; (2) estimate the effects of refuge hydrologic management and restoration on carbon sequestration, fire management, and establishing selected types of resilient vegetation communities; and (3) provide an assessment and valuation of selected ecosystem services including carbon sequestration, wildlife viewing (biodiversity, recreation), nutrient cycling, flood protection, and fire mitigation.
This study will inform how hydrologic management affects carbon storage in peatlands (important global carbon sink) and what approaches may be used to restore selected vegetation community habitats and improve ecosystem services including carbon sequestration.
