Submerged aquatic vegetation (SAV) provides ecological services in Chesapeake Bay. We used cost distance analyses to quantify the influence of SAV distribution and density on future SAV. For a spatially balanced sample of potential habitat sites, logistic regression quantified the effect of distance to other SAV on SAV density. Comparing across regressions for different years tested for effects of water quality. Software used includes ArcGIS 10.1 for desktop, arcpy, numpy and R.
