Riparian Shrubland

Riparian shrublands receive the most amount of natural flood-related disturance of the three riparian woody wetland types. Riparian shrublands occupy shorelines, low rocky shelves just above the waterline, higher portions of sand, gravel, cobble, and boulder bars. They are routinely battered by floodwaters and often from the debri carried by those floodwaters. Debris such as logs, branches, leaves, and other detritus often collect and accumulate in riparian shrubland communities. These communities are often species-poor and are dominated by shrubby willows ( Salix  spp.), indigo-bush ( Amorpha fruticosa ), ninebark ( Physcocarpus opulifolius ), fringetree ( Chionanthus virginicus ), winterberry holly ( Ilex verticillata ), and St. John's-wort ( Hypericum  spp.).
