A number of factors contribute to overall risk of water quality impacts related to timber harvest. Here, we summarize a variety of physical and hydro-geologic characteristics related to each of our watershed sample units, which may contribute to the potential for sediment and nutrient contribution from harvest sites to surface waters. These characteristics are best viewed as baseline conditions which could influence potential impacts to water quality in the absence of FMG implementation. These factors range from percent forest cover within a watershed to soil erosivity, and include slope, concentration potential for runoff, land use, distance to surface hydrology, and a variety of other factors. It is critical to keep in mind that our summaries of the resulting models tend to average conditions across the entire watershed sample unit, while certain conditions may actually be concentrated along stream corridors, steep and narrow valleys, glacial moraine edges, or other physical features present in the watersheds. The series of maps resulting from this analysis shows these factors on a landscape level. Most factors are derived from map layers created at a 30 meter resolution (e.g. pixel size on the ground). Hence, our background erosivity risk model also describes these factors at the 30 meter scale. |
