Vegetation/Open Water Dispersion - wetland type/open water condition metric (evaluate for Non-Tidal Freshwater Marsh only) Select the figure that best describes the amount of interspersion between vegetation and open water in the growing season. areas indicate vegetated areas, while solid white areas indicate open water. ?A ?B ?C ?D Patterned 22. Hydrologic Connectivity- assessment area condition metric Evaluate for riverine wetlands only. Examples of activities that may severely alter hydrologic connectivity include intensive ditching, fill, sedimentation, channelization, diversion, man-made berms, beaver dams, and stream incision. ?A Overbank and overland flow are not severely altered in the assessment area. ?B Overbank flow is severely altered in the assessment area. ?C Overland flow is severely altered in the assessment area. ?D Both overbank and overland flow are severely altered in the assessment area.
