Watershed land use and its influence on nutrient and organic matter loading to coastal lagoons is a important long-term driver of change in the VCR/LTER. The VCR mainland landscape can be divided into 57 sub-watersheds that drain into coastal lagoons and vary with respect to land use/land cover. The individual watersheds range in size from 0.2 – 19.7 sq. km. These small watersheds feed into 9 lagoon systems in the VCR. We monitor baseflow nutrient loading of groundwater into tidal creeks located in watersheds with different land use/land cover.
