Blue areas indicate wetlands for which there are insufficient data to analyze. Please click on the map to see a larger view. Those wetlands that rate as moderate to high in capacity may be particularly important in protecting water quality in the region. Because these wetlands have some ability to moderate nitrogen levels, they are most likely providing important water quality benefits to waters that flow from or through them. Nitrogen fixing to sediments was insignificant in this county, due mostly to the fact the the soils are composed of sand or organic matter.
Clay soils are rare, so permanent fixing of ammonium to sediments is negligible in most areas.
