3 1.0 INTRODUCTION The Ohio Department of Transportation (ODOT) contracted with The Dawes Arboretum (Dawes) and Envirotech Consultants, Inc. to compile a final mitigation plan for a 71-acre parcel in row crops in Licking Township, Licking County, Ohio. The site was acquired by Dawes for habitat restoration and conservation, and is contiguous to the arboretum preserve. The mitigation will be conducted on behalf of the ODOT in connection with unavoidable wetland impacts associated with its State Route 161/37 improvement project. Approximately twenty-one (21) acres of wetlands will be restored (re-established) in hydric soil in the agricultural fields, which are located in the same USGS watershed as the majority of the impacts. An additional fifty (50) acres adjacent to the wetland restoration will be restored to a mesic-wet mesic prairie with nearly five (5) acres of this buffer likely to become jurisdictional wetland. The majority of the mitigation wetlands will have water regimes ranging from seasonally inundated or saturated to regularly inundated or saturated (Zones II to IV, Table 5, COE, 1987). Some wetland areas are expected to attain semipermanently to nearly permanently inundated to saturated hydrology (Zone II), however, no more than 5% of the wetlands will have permanent inundation greater than 24 inches during years of typical precipitation (Zone I). A minimum of twenty-one (21) acres of Palustrine emergent (PEM), Palustrine scrub-shrub (PSS) and Palustrine forested (PFO) habitats will be restored at the site. Palustrine emergent (PEM) habitats include mixed emergent marsh, floating-leaved riparian marsh, hillside seeps, sloughgrass-bluejoint prairie and sedge meadow. Palustrine scrub-shrub (PSS) habitats include buttonbush swamp, alder shrub swamp and leatherleaf bog. Palustrine forested (PFO) habitats include tamarack hardwood bog and maple-oak-ash swamp, which will be the climax ecosystem to the sloughgrass-bluejoint prairie. The buffer is a big bluestem prairie complex. The site was constructed from October 2005 through late spring 2006 and planted during the growing seasons in 2006 and Dawes Arboretum dedicated the restored wetlands as the Dutch Fork Wetlands on August 28, General site photographs are found in Exhibits 1 through 5, and a project overview is found in Table 1 below. Monitoring of the mitigation wetlands for a period of five years following construction is required by the US Army Corps of Engineers (COE) and the Ohio Environmental Protection Agency (OEPA) to ensure that sufficient compensation for the impacted wetlands has been accomplished. This is the Year 5 and final monitoring report.

Maintenance and Remediation Recommendations for Remediation State Route 161/37 road improvements 3.95 acres of mostly Category 2 jurisdictional and isolated wetlands 21 to 26 acres of emergent, scrub-shrub and forested wetlands; 50 acres of buffer; excess mitigation available for future impacts of permit applicant Approximately 1 mile north of main entrance to The Dawes Arboretum; Licking County, O; see Figure 1 for mitigation site boundary From I-70, follow State Route 13 north approximately 4 miles to White Chapel Road; turn left and travel approximately ½ mile to mitigation site on left October 2005 through September 2007 including plant installation Yes, see Table 2 below See Section 6.0 below None 2.0 MITIGATION SITE DESCRIPTION 2.1 Site Description The site comprises nearly flat floodplain associated with Dutch Fork and nearby tributaries and adjacent uplands consisting of low relief rises and knolls, which have a long farming history (USDA-SCS, 1992). Prior to the wetland restoration, nearly the entire 71-acre mitigation site was farmed. Surface water hydrology at the Dawes site involves three principal watersheds associated with two branches of the unnamed perennial tributary that bisects the site. The three watersheds located north and northeast of the site comprise a total of ±225 acres, most of which is in conservation management by Dawes. Dutch Fork s active 100 year floodplain includes areas adjacent to the stream and the on-site channelized tributaries where surface water tends to saturate soils rapidly and pond in depressions. The general pattern for surface water drainage from the site is southward to Dutch Fork. The local landscape surrounding the Dawes parcel and within approximately a ½ mile radius includes land in conservation management for plants and wildlife, agriculture and residential development, mostly north of White Chapel Road. Between the radius of approximately ½ mile and one mile the land use is predominantly agriculture. Dutch Fork and its associated riparian floodplain zone parallel the south part of the site, which is forested and dominated by mature floodplain trees, Platanus occidentalis (American sycamore), and shrubs/small trees, Acer negundo (box elder). 2

5 2.2 Description of Mitigation Wetlands Two, more or less independent, hydrologies will drive wetland restoration at the Dawes site. This includes wetland restoration for ±21 acres in the eastern part of the site and restoration of an additional ±5.7 acres in the western part of the site. The watershed for the eastern wetlands is approximately 185 acres, while the watershed for the additional wetland restoration in the western portion of the site is approximately 40 acres. Restoration will establish hydrologic conditions in the mitigation wetlands which have seasonally inundated and/or saturated soils to nearly permanently inundated and/or saturated hydrologic regimes. For these regimes, the minimum inundation and/or soil saturation would occur during >12.5% of the growing season, the minimum hydrology for a Zone IV hydroperiod, to >75%, the minimum hydrology for a Zone II hydroperiod (COE, 1987). During years with normal precipitation, the semipermanent and/or permanent pools will occur in Zone II areas, with some relatively small areas of open water (<6.6' water depths) meeting the minimum inundation for a Zone I hydroperiod. Areas with Zone III hydroperiods will be transitional between Zone II and Zone IV hydroperiod areas; soil saturation will prevail in Zone IV areas (typically 12.5% to 25% of the growing season). 3.0 MITIGATION GOALS The objective of the restoration plan is to restore a complex of high quality emergent, scrub-shrub and forested wetland communities (approximately 21 acres), with an adjacent buffer restored to a big bluestem prairie complex (approximately 50 acres). According to the classification system described by Cowardin et al (1979), all of the restored wetland habitats will fall into the Palustrine ecological system. The emergent herbaceous habitat will include persistent and non-persistent subclasses. Forested and scrub-shrub class habitats will include the broadleaved deciduous subclass. Permanent management by Dawes will provide recreational and educational benefits for the surrounding communities. Environmental education about wetlands will be featured in the Arboretum s programs, as well as in interpretive signs proposed for the site. Environmental education at the Arboretum complements its natural history programs. Interpretive programs, plant plots and bird blinds are several of the tools available for the community s use in exploring the wetlands (Dawes Arboretum, 2007). In 2011, nearly 700 visitors, including representatives of educational, natural resource and conservation organizations, participated in educational, training or volunteer programs at Dutch Fork Wetlands. Among the visitors were 400 students from regional middle and high schools participating in Envirothons (see Exhibits 9 and 10) and friends and family of a local Eagle Scout whose constructed bridge trail connector will be enjoyed by visitors to the wetlands for years to come. 4.0 WETLAND MONITORING METODOLOGY The monitoring will evaluate plant composition and cover, document wildlife use, evaluate the successional development of the habitat, and determine whether remedial measures are necessary. Monitoring will take place for 3

6 a period of five years following construction of the site. An on-site meeting will be arranged with the COE and OEPA on the third year following construction to evaluate the wetlands. Reasonable modifications identified by the COE and OEPA will be undertaken, if necessary. At the end of the monitoring period, the COE and OEPA will determine whether the site can be released from monitoring and remediation responsibilities. The performance goals for the mitigation wetland include: Restored wetlands must, at a minimum, meet the hydrologic criteria for jurisdictional wetlands as defined by the COE (COE, 1987). In general, the hydrologic regimes set forth within the conceptual wetland restoration plan will be met with the majority of the mitigation site having regimes ranging from seasonally inundated or saturated to regularly inundated or saturated (Zones II to IV, Table 5, COE, 1987). Some areas of the mitigation site are expected to attain semipermanently to nearly permanently inundated to saturated hydrology (Zone II), however, no more than 5% of the mitigation site will have permanent inundation greater than 24 inches (61 cm) during years of typical precipitation. At the end of the monitoring period, the restored wetland areas should contain a minimum of 80% areal coverage by facultative, facultative wetland and obligate wetland native perennial plant species. In addition, <5% of the total areal coverage should consist of invasive/exotic plant species such as giant reed (Phragmites australis), purple loosestrife (Lythrum salicaria), narrow-leafed cattail (Typha angustifolia), blue cattail (Typha x glauca), common buckthorn (Rhamnus frangula), Japanese knotweed (Polygonum cuspidatum), and reed canary grass (Phalaris arundinacea). The restored wetland communities will be assessed during the final year of monitoring using the standard protocols in the Field Manual for the Vegetation Index of Biotic Integrity(VIBI) for Wetlands v.1.4. and are expected to achieve Category 2 or 3 vegetation IBI scores. The scoring ranges for depressional emergent wetlands for the Erie Ontario Lake Plain are (Category 2) and (Category 3) (Mack 2004, 2006).

7 5.0 MONITORING DATA Year 5 (2011) Final Post-Construction The monitoring completed during the 2011 growing season included 12 5m diameter routine vegetation and hydrology plots on June 3 and July 25, and 7 VIBI 10x10m random plots and 2 20x50m focus plots in July and August. Vegetation and hydrology monitoring in wetlands using the 5m diameter routine plots included 1 8, while the VIBI assessment included random plots 114, 144, 364 and 681 and both 20x50m VIBI focus plots. The remaining plots were used to assess the surrounding buffer areas (Figure 1). All of the wetland monitoring was performed in delineated wetlands. As of the end of the 2010 monitoring season and an interim wetland delineation performed that year, monitoring plots 9 12 were determined to be nonwetland and were included with the buffer monitoring. The Year 5 (final) wetland assessment is based on the more robust VIBI method using four 10x10m random and two 20x50 fixed plots. Assessment of the surrounding buffer area is based on three 10x10m VIBI random plots. All of the 2011 plot monitoring data is located in Appendix A. Following the Ohio EPA s VIBI protocols the four wetland random plots were combined to obtain an aggregate score for overall wetlands at the site. Exhibits 1-4 show representative wetland areas among the random plots. The aggregate sample from the four random plot modules scored 74, which placed it in the high range for Category 2 herbaceous emergent wetlands (PEM) for the Erie Ontario Lake Plain. The two fixed plots also were located in representative emergent wetlands; fixed plot 1 in the southeast part of the site scored 74 (high range Category 2) and fixed plot 2, located in the north central part, scored 94 (Category 3). The VIBI scoring range for Category 2 is and for Category 3 is (Mack, 2007). The year 5 buffer VIBI score was 67 based on an aggregate of three 10x10m plot samples. The wetland and buffer VIBI data are summarized in Table 3 below. A qualitative assessment based on the vegetation and FQAI scores indicated good wetland and buffer development for the overall site in 2011, with the total number of plant species reaching 208 (85% native species) and a FQAI score of A cross section of the FQAI scores along representative hydrology zones, based on plant indicator status, was 18.6 (FAC), 28.9 (FACW) and 29.7 (OBL). The FQAI for the overall buffer area was The plant list and FQAI scores for the site from 2007 through 2011 are found in Appendix B. Additional data for the site includes plant lists compiled by David Brandenburg, Taxonomist, The Dawes Arboretum for the Dutch Fork wetlands and the entire complex including the riparian corridor (included in the Year 4 report), and wildlife observations compiled by the Dawes Arboretum staff and their numerous partners for the Dutch Fork wetlands and riparian corridor (Exhibits 8-10; Appendix C). Appendix C also includes the results of butterfly monitoring for the Ohio long-term butterfly monitoring project. 5

The table also includes the automated spreadsheet results for the upland buffer using data from 3 aggregated 10x10-meter plots, scored as the emergent vegetation class. 6.0 MANAGEMENT AND MAINTENANCE ACTIVITIES Management activities during 2011 included planting of additional woody and herbaceous plants, adding a new section of trail, installing a rain-garden on the south side of the observation deck, a prescribed burn of the prairie buffer, mowing, and mechanical control (in some species cut stems were also treated with Roundup ) of invasive species including Typha and Lonicera spp, Phragmites australis, Rosa multiflora, Cirsium arvense and Dipsacus fullonum. Dawes staff also inspected berms and water control structures and made repairs to berms damaged by muskrats. The final year compliance visit was held on September 20, 2011 (See Exhibits 5 and 6 for photographs of some of the participants.) 7.0 DISCUSSION The fifth year monitoring found very good wetland development and final year VIBI assessment scoring the overall emergent herbaceous wetlands (PEM) in the high Category 2 and mid Category 3 ranges and meeting all of the site s performance goals. The VIBI assessment included a representative cross section of PEM wetland development with a number of plots including areas of scrub-shrub (developing PSS vegetation class) and components of forested wetland (early developing PFO vegetation class). Exhibits 1-5 and 7 show the progress of vegetation development within the acres of wetland delineated in 2011(Figure 1). In 2011 the PEM vegetation class was estimated at acres and the PSS and PFO wetland vegetation classes were estimated at 1.72 acres and 2.68 acres, respectively. Unvegetated open water >24 in depth was estimated at 0.46 acres. 6
