Carbon dioxide emissions: Spatiotemporal variation in a young and mature riparian forest

Forested riparian zones in agricultural landscapes provide multiple ecological services including nutrient abatement and carbon (C) sequestration. However, limited information exists on CO2 emissions from rehabilitated riparian forests, which could negate their C sequestration potential. The objecti...

Description
Summary:Forested riparian zones in agricultural landscapes provide multiple ecological services including nutrient abatement and carbon (C) sequestration. However, limited information exists on CO2 emissions from rehabilitated riparian forests, which could negate their C sequestration potential. The objective of this study was to evaluate temporal and spatial variation of CO2 emissions, and its relationship to soil and vegetation characteristics, in a 30-year old riparian zone rehabilitated with trees (RH) compared to a 150-year old undisturbed natural (UNF) riparian forest. Soil moisture, temperature, C, total nitrogen (TN) and vegetation characteristics (light intensity, distance to the nearest tree) were significantly (p
