The succession of vegetation, soil development, water quality changes, and carbon and nitrogen dynamics are summarized in this article for a pair of 1-hectare flow-through-created riverine wetlands for their first 15 years. Wetland plant richness increased from 13 originally planted species to 116 species overall after 15 years, with most of the increase occurring in… More

Wetlands provide important ecosystem services and store carbon dioxide but are also an important global source of methane – a potent greenhouse gas. In order to understand the dynamics of methane emissions from a temperate reconstructed wetland, methane fluxes were measured continuously over 2 years using the eddy covariance method in the Olentangy River Wetlands… More

Methane (CH4) emissions were measured at the Wilma H. Schiermeier Olentangy River Wetland Research Park (ORWRP) over three summers and two winters using an eddy covariance system. We used an empirical model to determine the main environmental drivers of methane emissions. Methane emissions covary strongly with water vapor fluxes, CO2 fluxes, and soil temperature. We… More
