This map portrays the assessment results by summing the Ag+ Urb riparian land cover and dividing it by the total riparian land cover at the 8-digit HUC spatial unit. Although this map serves to identify relative differences among HUCS, it does not illustrate absolute differences among HUCs in terms of the total quantity of stream kilometers (i.e., the total riparian buffer area) present within each spatial unit. In other words, we cannot tell by looking at this map which of the HUCS with the highest Percent Disturbance has the largest total riparian buffer.

This data set is a complete digital hydrologic unit boundary layer of the Subbasin (10-digit) 5th level for the entire United States, clipped to the Northeast. A hydrologic unit (HU) is a drainage area delineated to nest a multi-level, hierarchical drainage system. Its boundaries are defined by a hydrographic and topographic criteria that delineate an area of land upstream from a specific point on a river, stream, or similar surfaces waters. An HU can accept surface water directly from upstream drainage areas, and indirectly from associated surface areas such as remnant, non-contributing, and diversions to form a drainage area with single or multiple outlet points. HUs are only synonymous with classic watersheds...
