3 INTRODUCTION Herpetological Associates (hereafter HA) was retained by Maser Consulting P.A. (Maser) to conduct a bog turtle (Glyptemys [Clemmys] muhlenbergii) presence or absence survey (Phase II) on 7.19 acres of wetlands associated with Block 59, Lots 4, 5 and 3.01 (Figures 1 and 2). The survey was conducted with regard to the proposed alignment of the Mullica Hill US Route 322 Bypass project in Harrison Township, Gloucester County, New Jersey. The survey was conducted using the guidelines set forth by the United States Fish and Wildlife Service s Guidelines For Bog Turtle Surveys (revised May 2006). HA initially surveyed (Phase II) this area in 2004 and did not observe any evidence of bog turtles on or in the vicinity of the project site. The information regarding these surveys can be found in a report entitled: Results of Phase II Bog Turtle Surveys in Mullica Hill, Harrison Township, Gloucester County, New Jersey submitted 7/13/04 to James P. Stewart, Craft Stewart, LLC, 16 High Point Drive, Medford, NJ HA File Number Unless otherwise noted on plans, wetlands were delineated by Kevin Jamieson and Jacqueline M. McCort of Maser, One River Centre, Building Two, Newman Springs Road, Red Bank, New Jersey, (732) Wetlands associated with the project area that were not delineated by Maser were part of previously submitted wetlands delineations and were subsequently issued L.O.I. s by the New Jersey Department of Environmental Protection (NJDEP). Some of these wetlands were delineated by Douglas A. Freese, Greenvest, February, MATERIALS AND METHODS Location of the Study Site The study site is located east of Main Street (NJ Route 45), north of Mullica Hill Road (US Route 322), and west of Walters Road in Harrison Township (Figures 1 and 2). Racoon Creek and its smaller tributaries, such as Jefferson Branch which runs through the project area, flow from east to west. Surveyors The following HA staff members were present at some or all of the surveys: David Schneider, Matt McCort, Ray Farrell, Bill Callaghan, Brian Farrell, Cathy Eser, Daniel Iovine, Matt Lanier and Pete Mooney. Dave, Matt, and Ray are all USFWS recognized qualified bog turtle surveyors. At least one USFWS recognized qualified bog turtle surveyor was present at each of the surveys. Bog Turtle Survey Methods HA conducted its bog turtle survey in a systematic fashion using a team of experienced herpetologists including at least one USFWS recognized qualified bog turtle surveyor and field assistants. The protocol for conducting this presence or absence survey consisted of walking through the wetland while carefully looking for basking turtles in shallow, muddy water, atop or amid grasses, and in or on dead/decaying plant debris. Wooden probing sticks (i.e., broom handle) were used to move vegetation aside and to probe into soft mud in search of hidden turtles. Additionally, shallow water and muddy substrate was searched by muddling (i.e., feeling around in the mud by hand, Ernst and Bury 1977). HA staff also searched for turtle footprints or tracks in soft mud, Herpetological Associates, Inc. 1

6 searched for eggs, egg shells, turtle shells or bones of the species in all suitable areas within the wetlands (Ernst, Lovich, and Barbour 1994; Herman 1994). HA used two standard sampling methods to survey for reptiles and amphibians in this study: random opportunistic sampling (ROS), which examines an entire site, including both high and low potential areas; and time-constrained searching (TCS), which focuses on areas within a site with high habitat potential. HA used the ROS method primarily during its initial surveys of the site. This enabled HA to first observe all habitats and then determine specific locations of potential bog turtle habitat. TCS was used in later surveys, after potential bog turtle areas were delineated within the site. Details of these two methods follow. ROS (Random Opportunistic Sampling) ROS involves searching all areas of a site, regardless of the potential for bog turtle habitat. This allows for the identification of areas of potentially suitable habitat within a site. All herptiles, birds, and mammals encountered are recorded to supplement the species list generated by other field methods. Through the employment of this method, qualitative impressions can be developed as to the relative abundance and habitat use of certain species (Campbell and Christman 1982; Karns 1986). TCS (Time-constrained Searching) The TCS method is most effective when searching for very secretive forms of wildlife (e.g. bog turtles). A specific habitat, such as a cattail swamp, open Carex marsh, or spring-fed meadow is selected and an experienced team of 3 persons conducts an intensive, timed search within the area. Depending on the number of times an area is to be searched, all individual reptiles and amphibians encountered can be uniquely marked to avoid counting animals twice or to obtain a population estimate. Spatial boundaries for each search are limited to the selected habitat. During times of the year when target species are known to congregate in particular habitats (e.g. nesting and spring areas) for some aspect of their life history (e.g. egg laying and hibernation), TCS is highly productive and superior to other types of surveys. Time limits ensure that each habitat is adequately, but not excessively examined. This method allows a quantitative comparison of species richness, relative abundance, and movement between habitats (Campbell and Christman 1982; Karns 1986). Herpetological Associates, Inc. 4

7 RESULTS PHASE I SURVEY RESULTS A habitat evaluation (Phase I) survey was conducted on January 18, 2008 by Matthew McCort and David Schneider of HA. The Phase I habitat descriptions and results were previously included in our Phase I report entitled: Phase I Habitat Evaluation at the Proposed Mullica Hill Bypass Site in Harrison Township, Gloucester County, New Jersey submitted to Maser Consulting, P.A. on January 23, The results of the evaluation concluded that Wetland 2 (3.0 acres) was the only wetland that was determined to be potential bog turtle habitat (Rank 4 typical). However, to avoid any confusion or discrepancies with the 2004 survey area, HA was instructed by Maser to survey the same 7.19 acre area again in 2008 (Figure 4). The survey area also includes Wetland 1 (4.19 acres). See Appendix for a copy of the scientific collecting permit issued by New Department of Environmental Protection (NJDEP) Division of fish and Wildlife. Habitat Description Two wetland habitat types on the Mullica Hill site, forested stream corridor, and scrub-shrub/ emergent wetland were surveyed for the presence of bog turtles in 2008 (Table 1). The following habitat descriptions initially appeared in HA s July 2004 Phase II and January 2008 Phase I survey reports. Wetland 1: Forested Stream Corridor (Figures 4, 5 and 6) The forested stream corridor is 4.19 acres in size and commences at the northern corner of Block 59, Lot 5. It flows along the western border in a north-southwest direction to the eastern border of Block 59, Lot The substrate in the stream consists mainly of sand and gravel, with deposits of organic matter. A small feeder stream flows in from the west near the border of Block 59, Lot 5 and Lot The stream corridor is completely forested throughout Block 59, Lot 5 which is under a thick canopy of large old-growth deciduous trees. Dominant trees in this area include tulip-tree (Liriodendron tulipifera), red maple (Acer rubrum), sassafras (Sassafras albidum), sycamore (Platanus occidentalis), and American beech (Fagus grandifolia). Other tree species include flowering dogwood (Cornus florida), box elder (Acer negundo), and ironwood (Carpinus caroliniana). Because of the heavy tree canopy, the understory consists mainly of saplings of the aforementioned tree species. Vine species consist of patches of poison ivy (Toxicodendron radicans), wild grape (Vitis spp.), Japanese honey suckle (Lonicera japonica), greenbrier (Smilax spp.), and Virginia creeper (Parthenocissus quinquefolia). The ground cover consists mainly of skunk cabbage (Symplocarpus foetidus), Jack-in-the-pulpit (Arisaema triphyllum), mayapple (Podophyllum peltatum), and jewelweed (Impatiens capensis). The surrounding forest rises to an elevation of 3-10 m above the stream corridor. In some areas, small springs flow underground from the surrounding uplands, emerging at the stream edge creating a mucky substrate (0-1 m deep). However, because of the heavy canopy (little light penetration) and lack of suitable vegetation (no sedges for egg laying), as well as the location of the mucky substrate (at the stream edge which would be prone to flooding during heavy rain), this area is atypical (Rank 2) for bog turtles.

8 Wetland 2: Emergent Wetland (Figures 4, 7, and 8) Wetland 2 is an open emergent wetland, approximately 3.0 acres in size, located downstream and west of Block 59, Lot 5. It commences at the western edge of Block 59, Lot 5, forms the northern edge of Block 59, Lot 3.01, and terminates at the eastern end of Block 59, Lot Wetland 2 is primarily an emergent wetland with a scrub/shrub component that occurs in patches throughout. Dominant trees and shrubs occurring in the wetland include red maple, multiflora rose (Rosa multiflora), arrowwood (Viburnum dentatum), alder (Alnus spp.), silky dogwood (Cornus amomum), and black willow (Salix nigra). This wetland, for its entire length, is bordered by the same old-growth deciduous forest and high elevation as described above. Emergent vegetation includes sweet flag (Acorus calamus), sensitive fern (Onoclea sensibilis), tearthumb (Polygonum spp.), common arrowhead (Sagittaria latifolia), jewelweed, and rice cutgrass (Leersia oryzoides). Various sedge species (Carex spp.), including tussock sedge (Carex stricta), are present in small numbers. Common reed (Phragmites australis) is becoming established in the eastern end of the wetland near Block 59, Lot 5. Wetland 2 is fed by Jefferson Branch and a few springs and seeps that flow from the surrounding uplands. At the eastern end of the wetland near Block 59, Lot 5, Jefferson Branch splits into two smaller streams, which form the northern and southern borders of the open wetland. A few rivulets flow in a northwesterly direction from the stream along the southern border to the stream branch on the northern border. These streams eventually converge near the center of the wetland, and Jefferson Branch continues on as the southern border of the wetland. East of the stream convergence the northern portion of the wetland is fed primarily by a few springs that flow into the wetland from the uplands on the north side. Mucky areas (5 cm- 1m deep) are present particularly in areas where springs and seeps are present. Because of the existence of patches of suitable habitat, including indicator vegetation, suitable soils and hydrology, this area is typical (Rank 4) for bog turtles. Table 1.
