Site Visit The City of Orono requested that about 100 feet of wetland be delineated on the subject property. SER ecologists examined the subject property, as directed, for areas meeting jurisdictional wetland criteria during the site visit. One area meeting the jurisdictional criteria of a wetland was flagged, and boundaries were determined and delineated. The approximate wetland boundary is outlined in yellow (Figure 5). Wetland 1 is a Type 2 PEMB Wet Meadow, an open herbaceous depression in an area otherwise densely wooded by young shrubs. The vegetation is dominated by reed canary grass (Phalaris arundinacea, FACW) and glossy buckthorn (Frangula alnus, FACW). The adjacent upland area has a sparsely vegetated herb layer with increased dominance of buckthorn and other woody species. This vegetative transition is characteristic of the transition from wetland to upland, though in the southern extent of the wetland the topography slopes upwards and lacks evidence of wetland hydrology while maintaining reed canary grass cover for a short distance before transitioning to a buckthorn dominated cover. A sample transect was established at this location. Soils at sample point SP 1-1 Wet consisted of a layer of modified mucky mineral soils at the surface with clay pan below. Hydric indicator F1 (Loamy mucky mineral) was identified. There were also several indicators of wetland hydrology at this site: B8 (Sparsely Vegetated Concave Surface) and B9 (Water Stained Leaves). At sample point SP 1-1 Up the soils were of a similar hue and chroma to the wetland point, however they lacked the high percentage of organic material found there. No hydric indicators were present, and no indicators of wetland hydrology were present at this upslope sample point. This wetland is not present in the National Wetland Inventory nor is it present in the DNR Public Waters Inventory. Detailed soils, vegetation, and hydrology data for the delineated jurisdictional wetlands are provided in the data sheets of the Technical Documents section. DISCUSSION SER completed all on-site delineations based on the three required technical criteria as outlined by the 1987 Manual: the presence of hydric soils, a predominance of hydrophytic vegetation, and indicators of wetland hydrology in each basin. The site visit portion of the wetland delineation was completed on 6/11/13. SER personnel examined the subject property for areas meeting jurisdictional wetland criteria during the site visit and delineated the edge of one basin as being jurisdictional wetland (Figure 5). Detailed soils, vegetation and hydrology data is provided in the data sheets of the Technical Documents section. A set of figures is provided in the Figures section.
