1 Abbreviations: CPCN = Certificate of Public Convenience and Necessity; NPDES = National Pollution Discharge Elimination System; BOA = Board of Appeals 2 While the FCA is ordinarily implemented at the county level, the exemption for projects subject to a CPCN under Natural Resources Article 5-1602(b)(5) and 5-1603(f) supersedes county-level implementation with the Commission’s “due consideration [of] the need to minimize the loss of forest and the provisions of afforestation and reforestation set forth in [the FCA] together with all applicable electrical safety codes.” Md. Natural Resources Article 5-1603(f).

Introduction
Invenergy, a developer of solar power collection and transmission utility sites, is considering a
location for the installation of a new facility. This report addresses the potential for historical
and cultural resources (Phase Ia archaeological and historic structures survey) within the project
area and the Area of Proposed Effect (APE). The proposed site for the Todd Solar Center is
located on the near the town of Hurlock, on Harper Road, on the Eastern Shore of Maryland in
Dorchester County, approximately 14 miles southwest of the county seat of Cambridge (Figure
1). The site is located within the Coastal Plain Province, Maryland Archaeological Research Unit
3 - Nanticoke-Wicomico-Manokin-Big Annemessex Drainage (Figure 2).
Figure 1: Project Location in Maryland
The project property is located approximately 1.5 miles southwest of Hurlock, Maryland, a small
town of 2.88 square miles at the intersection of MD Routes 331 and 392. The project area is not
within the town boundaries. The immediate area is rural and agricultural.
The site is located within the Nanticoke River watershed (Figure 3). The property consists of a
143.3-acre parcel of agriculture land currently under cultivation with soybeans and potatoes. The
parcel is bisected by Wright’s Branch that runs into Marshyhope Creek, a tributary of the
Nanticoke River. The property’s eastern boundary is approximately one-quarter mile from
Marshyhope Creek.
The property is bounded by Harper Road to the east, Ennals Rd to the south, Skeet Club Road to
the north, and the Hurlock Sewage Treatment Plant (on Jones Villa Drive) to the west: large
wastewater treatment ponds abut the project property (Figure 4).

Property Description
The proposed project area is situated in a rural setting abutting a wastewater treatment plant and
levied management ponds. The 143.8-acre site has been cleared of vegetation, save a buffer of
trees that bisects the property, following a creek that runs through the parcel (Figure 5). The
land is flat with virtually no variation in elevation. It is currently utilized a farmland and has
been such for the last century. There is very little residential development in the immediate area
with the largest concentration of housing located 1.5 miles to the northwest.

Cultural Context
Regional Prehistory
The following summaries of regional prehistory of the Potomac River Valley and the Mid-
Atlantic Region have been taken from the works of LeeDecker, Martin, and Friedlander (1988)
and Weinberg, Lawrence and Schopp (2007). The prehistory of the Potomac River Valley and
Mid-Atlantic region has been traditionally divided into three major periods, the Paleo-Indian,
Archaic, and Woodland. A fourth time period, the Contact Period, marks the final phase of
occupation by Native American groups in the Mid-Atlantic region.
Paleo-Indian Period (circa 11,000 to 8,000 B.C.) is characterized by a hunting and gathering
subsistence pattern, followed by small kin-base bands who hunted cold-adapted animals such as
caribou, mastodon, and woodland bison (Weinberg, Lawrence and Schopp 2007). Fish and
foraging for plant resources were also presumably important in their diet. Paleo-Indian finds in
Maryland are poorly represented, with only a few intact sites including the Higgins Site and over
a hundred isolated stone tools found (Dent 1995 and Ebright 1992).
Archaic Period (circa 8,000 to 1000 B.C.) lifeways are characterized by hunting and gathering
of a variety of food resources within a relatively well-defined territorial area, while continuing
the traditions from the Paleo-Indian Period. Settlements expanded into more diverse
environments, gathering a wide variety of shellfish, fish, game and plant food resources such as
nuts, berries, and roots (Dent 1995). The appearance of the Corner-Notched Tradition (7,500-
6000) and the Bifurcate Tradition (6,800 to 6,000) represent tool style changes characteristic of
the Early Archaic Period.
While the Middle Archaic tool kits continued to resemble those of previous periods, several
types of ground-stone tools were added for processing an expanded resource base. A variety of
grinding tools, such as mortars and pestles, indicate the increased reliance on plants in their diet.
The Late Archaic Period (circa 4,000 to 1000 B.C.) is marked by a greater emphasis on local
resource exploitation. Settlement patterns are found more along interior drainages, with larger
social groupings and increased sedentism (Mouer 1991 and Steponaistis 1980). Regionally,
evidence for permanent housing began to appear at this time (Griffin 1978). The establishment
of extensive trade networks and the introduction of complex mortuary practices are characteristic
of this period (Thomas 1973). Carved, lug-handled steatite bowls are one of the most noted
types of artifacts to be introduced to the Chesapeake Bay Region, indicating a more sedentary
pattern of existence (Dent 1995 and Tuck 1978).
Woodland Period (circa 1,000 B.C. to A.D. 1600) is better known than the Paleo-Indian and
Archaic Periods. The Early Woodland Period (1,000 - 300 B.C.) represents an increased
sedentary lifestyle for the native population, with larger, long-term sites being serviced by
outlying extraction sites (Mouer 1991). Domesticated cultigens, such as corn, beans, and squash,
together with wild glasses, such as amaranth and chenopodium, where gradually incorporated
Cultural Resource Assessment for the Todd Solar Center Site, Hurlock, Dorchester County, Maryland
7
into the daily diet. The flaked tool industry reflects Late Archaic technology with small bifaces,
drills, scrapers, and utilized flakes. Antler and bone tools have been recovered as well (Dent
1995). A rapid rise in ceramic technology flourished during the Early Woodland Period. The
earliest ceramics, Marcey Creek wares, were tempered with crushed steatite and formed in a
similar fashion as steatite bowls of the previous period (Mouer 1991). Other types of ceramics,
including Selden Island, Bushnell, and Croaker Landing wares, are possibly distinctive forms for
the Chesapeake Bay area (Custer 1989). Accokeek wares, featuring sand and quartz temper and
coil construction, eventually replaced Marcey Creek ceramics (Steponaitis 1980 and Wright
1973).
The Middle Woodland Period (300 B.C. to A.D. 900) witnessed the continued elaboration of
mortuary practices, including burial mounds and elaborate, exotic ceremonial grave goods
related to the Adena culture (Griffin 1967). These grave practices and goods indicate a shift
from a band level of social organization to complex rank societies, along with the emergence of
extensive trade associations beyond the immediate interior of Maryland. Pottery styles
continued to shift. Popes Creek, a thick-walled, and sand-tempered, net-impressed ware, and
Mockley, a shell-tempered cord-and net-impressed ware, are two dominant styles (Custer 1989,
Dent 1995, Steponaitis 1980 and Wright 1973).
In the Late Woodland Period (A.D. 900 to 1607), settlement patterns begin to reflect permanent
towns with a subsistence base focused on cultivated foodstuffs, such as corn, beans, and squash.
Floodplain locales are the favored locations for villages, based on the availability of fertile
bottomland soils for agricultural practices. Smaller base camps and procurement sites tend to
serve as specialized function sites with periods of multiple re-use. Ceramic diversity continues,
with a variety of motifs likely associated with the borrowing of designs from other societies
through established trade networks. Food sources were diverse and plentiful, including shellfish
and anadromous fish, nuts, starchy tubers, amaranth and goosefoot (Dent 1995).
Prehistoric Occupation in the Immediate Area
During the contact period (post 1607) and throughout the 17th century, the colony of Maryland
generally had good relations with the native inhabitants through a number of treaties. Some
persistent issues that caused strife were due to inter-tribal relations that arose when groups
traveled into or out of competing territories. The names of native groups on the Eastern Shore of
Maryland are memorialized in the names of the rivers that flow into the Chesapeake Bay and the
Atlantic Ocean; Wicomiss, Choptank, Nanticoke, Assteague, Pocomoke and Accomac (Dent
1995). The Choptank and Nanticoke groups are associated with Dorchester County, Maryland
and the adjacent area of what is now Delaware. The territories they occupied are related to the
watersheds that share their name. The proposed project area is located between the Choptank (to
the west) and Nanticoke (to the west) Rivers.
The Nanticoke Indians, and other groups on the Eastern Shore present during the initial contact
period (early 17th
century), do not appear to have the numbers or political groupings as those on
Cultural Resource Assessment for the Todd Solar Center Site, Hurlock, Dorchester County, Maryland
8
the Western Shore such as the Powhatan and Susquehannocks (Dent 1955). Of the groups
occupying the mid-shore (in sections of modern Maryland and Delaware) region during the Late
Woodland, the Nanticoke consisted of approximately 650 people (Dent 1995; after Feest 1978).
They were considered a distinct group that occupied the “… territory bounding the drainage
system of the Nanticoke River.” (Porter 1979: 326). As with many of the Algonquin associated
tribal groups in Tidewater Region, the Nanticoke began to leave the Maryland and Delaware
region in the mid-eighteenth century after agreements with colonial governments failed and after
white settlers did not honor Indian-land boundaries (Porter 1979). Many groups moved north into
the Pennsylvania but some remained on the Eastern Shore up to the period of the American
Revolution (Porter 1979).
Historical Context
Dorchester County, Maryland was formed by 1669 from sections of Somerset (1666) and Talbot
(1662) Counties. The countryseat of Cambridge was established by 1684. As with most colonial
settlement in the Chesapeake region, the navigable rivers and adjacent areas were settled first,
with interior settlement by subsequent generations. By 1790, Dorchester County had nearly
16,000 residents with 30% percent of the population consisting of slaves but the majority of the
population was concentrated near Cambridge, the seat of government and the court, and along
the Choptank River (US Census 1996).
The Town of Hurlock was not part of the colonial period development but was one of the towns
established along the railways in Maryland during the railroad build-out after the US Civil War
(mid 19th
century). The town is located at a crossroads and was not incorporated until 1892. It
was first settled in 1869 after to the construction of the Dorchester and Delaware Railroad. The
first resident and businessman in the area was John M. Hurlock. His storehouse was constructed
the year the rail line was complete in 1869 and he built a house in 1872: the town is named for
him (Jones 1902). By 1902, the town had 450 residents (Jones 1902). The most significant
period of growth was from 1890 to 1930. Currently, Hurlock is the second largest town in
Dorchester County and has a large historic district (D-653) (MHT 2008).
The subject property is currently owned by W & J McWilliams Farms, LLC and they have held
the property since 2009. The previous owner, Warren M. Saunders purchased in the land,
(consisting of three tracks) in 1979 from Ruth Ann Gadekar who inherited the land from her
father Samuel Harold Phillips in 1971 (Dorchester County 1971). Previous to 1971, the subject
property was owned by Olin P Conway (1925), George Hertzog (1907) and John L. and Charles
M Scott (1905). The Scotts purchased the land from John P. and Sarah R. Harper (1882) and it
was combined with a track from D W Davis (1899). In 1882, a 74-acre section of the parcel was
conveyed from Thomas Hubbert to the Harpers and is referred to as “being part of a track of land
called Airey’s Chance” (Dorchester County 1882). Thomas Hubbert purchased the land from
Robert W. and Mary Randall in 1879 and property the was also referred to as part of “Airey’s
Chance.” The Randalls had held it prior to 1872: they purchased it from Lewis Ross and Caleb
Shepherd (Dorchester County 1879). Prior to 1872, the land records did not provide chain-of-
Cultural Resource Assessment for the Todd Solar Center Site, Hurlock, Dorchester County, Maryland
9
title information. However, the track of Airey’s Chance was patented by John Pitt Airey in 1766
and was made up of parts of three previously patented parcels; Govert’s Chance (1704), Brooms
Chance (1704) and True Dealing (1686) consisting of 563 ½ acres (Dorchester County 1766).
The numerous conveyances in the 19th
century appear to be related to investments in the land
surrounding Hurlock and the development related to the railroad. A number of the owners lived
outside of the state. Land records indicate that it has historically been part of larger parcels and
used and/or leased for farming not residential occupation.

Site Conditions
Local Environmental Setting
As with much of the Eastern Shore, Dorchester County is sparsely populated with little
development. The majority of land use is agricultural or recreational due to the many waterways
and nature areas. “Dorchester County’s primary economies are agriculture and forestry-based.
Seafood processing from catching, cleaning, packing, and shipping, to the preparation of
seafood- is the primary economy in many of the village areas” (Cole 2008: 4). According to the
Maryland Department of the Environment,
Dorchester County covers approximately 354,870 land acres. Forty-eight percent (48%)
or 170,338 acres are zoned agricultural. Agricultural land dominates most of the
northeast portion of the county. Approximately 4% of Dorchester’s total land area is
developed. The remaining area is comprised of resource lands including forests,
agricultural lands, and wetlands. Tidal wetlands account for roughly 25% of the county’s
land area. Dorchester County’s wetlands account for approximately 39% of the entire
state’s wetlands (MDNR 2000).
As of 2005, “…woodland is a dominant feature of Dorchester County and… commercial
woodland consists of good quality loblolly pine as well as upland oaks, sweetgum, blackgum,
Virginia pine, holly, beech, or red maple, depending on soil wetness” (DSCD 2000:6).
The proposed project site in Hurlock is located between the Choptank and Nanticoke Rivers with
many feeder streams in the area. The two nearest bodies of water are Wrights Branch (which
bisects the project property) and Marshyhope Creek, a tributary of the the Nanticoke River. The
intersection of the Marshyhope Creek and the Nanticoke is approximately 7.5 miles downstream
from the project area. According to the Maryland Department of the Environment, “Marshyhope
Creek is existing stream valley greenways. This corridor is undeveloped and consists of
wetlands, marsh, and wooded banks that provide valuable habitat and stream protection”
(MDNR 2000).
Topography
Generally, the Eastern Shore of Maryland is flat with very little vibration in elevation. The
highest point in Dorchester County is at 57 feet AMLS between the upper reaches of the
Choptank and Nanticoke Rivers (MGS 2008). The proposed project area is nearly level at 25
AMSL and slopes to the southeast as it approaches the Marshyhope Creek.

Soils
The USDA, Natural Resources Conservation Service, classifies the dominate soil within the APE
as Galestown loamy sand (GaA) with 0 to 2 percent slopes. The setting consists of flats and
fluviomarine terraces with linear down- and across-slopes and the project area is nearly level.
The soils are somewhat excessively drained with the water table at 80 inches.

Surface Conditions and Signs of Disturbance
The portion of the project area considered for development consists of previously disturbed land
characterized by agricultural fields with a plow zone (Ap-the top most layer of the soil disturbed
to depth that a plow will penetrate, 12 to 25 cm, resulting in homogenizes soil layer), irrigation
well sites, drainage swales (some with culverts), and access roads. Wright’s Branch Creek
bisects the parcel and both sides of the creek are lined with a buffer of trees (Figure 8).
Figure 8: Project Area, Wright’s Branch
A review of historic topographic maps dating to 1905 indicates the northern section of the
proposed project site has been under cultivation since in early 20th
century: this was likely the
case in the 19th
century (based on the land records and land use patterned in the area). The
southern section of the parcel (below the creek) was mostly wooded until the mid-20th
century
but cleared converted to farmland by 1975. There is no domestic structure associated with the
current property configuration and only agricultural buildings and water-pumping infrastructure
are present. A review of aerial photographs dating to the 1960s, illustrate only farm-related
buildings. At the time of survey and reporting part of the property had recently been harvested
and the remainder cultivated with soybeans (Figures 9 and 10).

Historic Resources
There is no dwelling structure associated with the property and it’s current configuration.
According to the files and the GIS system at the Maryland Historical Trust/MD-SHPO, there are
no recorded historic structures extant within the APE (within a half of a mile) of the proposed
project area. However, there is a location with a MIHP number on the abutting parcel directly to
the north on Harper Road: the structure was town down ca. 2000. The Andrew Phillips Farm (D-
123) was recorded in 1975 and was noted as “a two-part frame dwelling, the earliest part being
one and one-half story, three bay long with a lean to on one gable and a two story, two bay long
structure on the other” (Bourne 1975). It was recorded as a 19th
century vernacular domestic
structure in deteriorated condition: it was not determined eligible for listing on the National
Register. The Phillips family owned the property from 1925 until 1979.
The housing abutting the property on the eastern boundary (near the intersection of Harper Road
and Palmer Mill Road) consists of trailer homes and small manufactured one level “ranch style”
houses. Similar types of housing are present on Ennall Road on the southern boundary of the
property near the water treatment plant facility.
The Hurlock Historic District (D-653) is located over 1.5 miles from the proposed project area
(to the northwest) and is outside the APE for direct effect. The Petersburg Survey District (D-
766) is located 0.60 miles from the proposed project area and it is outside the APE for direct
effect. The survey district and has not been formally evaluated for listing on the National
Register. Located at the southeastern most boundary of the survey district is the Zorah ME
Church, which dates to 1898, and although the Maryland Historical Trust in 1975 recorded it in
and in 2008 it has not been evaluated or determined eligible for the National Register.

Archaeological Resources
According to the files at the Maryland Historical Trust/MD-SHPO, there are six recorded
archaeology sites within 2 miles (the APE) of the proposed Todd Solar Center project area. All
are located east of the project site and east of Palmers Mill Road adjacent to Marshyhope Creek.
No Phase I surveys have been conducted on the subject property on or adjacent properties: there
are no recorded archaeological sites on the subject property.

Figure 11: Recorded Sites in the Immediate Area
The sites date from the Archaic (8,000 to 6,000 BCE) to through the historic period. The
environmental context falls within the generally accepted type for prehistoric settlement as
established by predictive models for the region. Land areas within 200 meters (656 feet) of
stream terraces, stream confluences, and water features generally have a moderate to high
probability for evidence of prehistoric occupation and settlement (A.D. Marble & Company
2006: 37-44). The subject property is located in an area with documented archaeological sites
and the environmental setting (proximity to Wright’s Branch) is one associated with prehistoric
occupation and settlement.

Planned Alterations
The proposed development of the subject property calls for minimal ground disturbance and
some limited excavation related to the installation of infrastructure for a solar energy collection
and distribution facility. As planned, the project would consist of photovoltaic (PV) panels and
steel racks installed in rows in the agricultural fields (Figure 12).
Figure 12: Typical Solar Panel Facility
Ground disturbance would be related to buried electric transmit cables, the installation of
approximately nine electricity inverters, and a small switchyard to be built on the site. An
electric circuit connecting the two fields of panels would be installed by underground directional
bore or overhead circuit. An eight-foot fence will surround the facility and a gravel road is
expected to be installed around the perimeter of the panel arrays. As the site is largely flat, little
to no grading is expected. The PV racks will be mounted on piles that can be installed without
excavation via boring. The area of the stream and wooded buffers would not be developed as
part of the project and appropriate setbacks will be established based on state/local regulations
(Figure 13).

Findings and Recommendations
There are no recorded historic resources, nor were any discovered during this survey, that
suggest that this planned undertaking would have a direct effect on historic resources. Moreover,
the abutting water treatment plant and related water treatment ponds have previously altered the
view shed of the property. No further study related to historic resources is warranted.
The subject property is located near an area with documented archaeological sites and the
environmental setting is one associated with prehistoric occupation and settlement therefore
there is a high to moderate likelihood that prehistoric or historic archaeological resources maybe
located within the APE and could be disturbed or destroyed by this planned undertaking. Phase I
archaeological testing is warranted to establish the presence or absence within the proposed APE
to determine the impact of development on archaeological resources.

WetlandsImpacts to and other aquatic habitats from your project may be subject toNWI wetlandsregulation under Section 404 of the Clean Water Act, or other State/Federal Statutes.
Project proponents should discuss the relationship of these requirements to their projectwith the Regulatory Program of the appropriate .U.S. Army Corps of Engineers District
DATA LIMITATIONS
The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level informationon the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery.Wetlands are identified based on vegetation, visible hydrology and geography. A margin of error is inherent in the useof imagery; thus, detailed on-the-ground inspection of any particular site may result in revision of the wetlandboundaries or classification established through image analysis.
The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts,the amount and quality of the collateral data and the amount of ground truth verification work conducted. Metadatashould be consulted to determine the date of the source imagery used and any mapping problems.
Wetlands or other mapped features may have changed since the date of the imagery or field work. There may beoccasional differences in polygon boundaries or classifications between the information depicted on the map and theactual conditions on site.
DATA EXCLUSIONS
Certain wetland habitats are excluded from the National mapping program because of the limitations of aerialimagery as the primary data source used to detect wetlands. These habitats include seagrasses or submergedaquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters.Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory.These habitats, because of their depth, go undetected by aerial imagery.
DATA PRECAUTIONS
Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in adifferent manner than that used in this inventory. There is no attempt, in either the design or products of thisinventory, to define the limits of proprietary jurisdiction of any Federal, state, or local government or to establish thegeographical scope of the regulatory programs of government agencies. Persons intending to engage in activitiesinvolving modifications within or adjacent to wetland areas should seek the advice of appropriate federal, state, orlocal agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect suchactivities.
Wetland data is unavailable at this time.

RE: Environmental Review for Todd Solar, 20 MW solar project, TM 23 P l, Town ofHurlock, Dorchester County, MD.
Dear Mr. Miller:
The Wildlife and Heritage Service has determined that there are no State or Federal records forrare, threatened or endangered species within the boundaries of the project site as delineated. Asa result, we have no specific comments or requirements pertaining to protection measures at thistime. This statement should not be interpreted however as meaning that rare, threatened orendangered species are not in fact present. Ifappropriate habitat is available, certain speciescould be present without documentation because adequate surveys have not been conducted.
Thank you for allowing us the opportunity to review this project. If you should have any fuitherquestions regarding this information, please contact me at (410) 260-8573.

1. Introduction
A critical habitat assessment was conducted for a site in Dorchester County, Maryland. The assessment
followed Tier 1 and Tier 2 of the U.S. Fish and Wildlife Service Land-Based Wind Energy Guidelines
(USFWS 2012) because similar guidance for solar development has not yet been issued by the U.S. Fish
and Wildlife Service (USFWS).
2. Project Location and Setting
The site (project area) is located on the west side of Palmers Mill Road approximately 1.5 miles south of
its intersection with MD 382, southeast of Hurlock in Dorchester County, Maryland. The site is located
in the Coastal Plain Physiographic province and is in a predominantly agricultural area that also includes
residential uses. A wastewater treatment facility is located west of the site.
3. Methods
Database Review and Landscape Level Assessment (Tier 1 of USFWS Guidelines)
A preliminary site evaluation was conducted that consisted of a landscape level assessment of habitat
for species of concern and a review of databases and other available information at the county, state
and federal level for sensitive species including rare, threatened and endangered species. The following
databases and sources were reviewed:
U.S. Fish and Wildlife Information for Planning and Conservation (IPaC) tool
Maryland’s Environmental Resources and Land Information Network (MERLIN)
Maryland Amphibian and Reptile Atlas (MARA) Database
USGS Maryland/DC Breeding Bird Atlas Project (BBA)
Maryland Department of Natural Resources Wildlife and Heritage Service List of Rare,
Threatened and Endangered Species of Dorchester County (April 2010)
Site Characterization and Analysis (Tier 2 of USFWS Guidelines)
A site characterization was completed to assess the potential presence of the species of concern
identified through the database review and landscape level assessment (Tier 1). For the site
characterization, the site was delineated into vegetative communities based on a review of leaf-off
aerial photography, soil maps, and topographic maps. A reconnaissance level site visit was conducted
on October 6, 2015 to field verify the delineation of the vegetative communities. In the mixed
hardwood forest community, a single transect was walked starting from the southeastern portion of the
site at Palmers Mill Road on the south side of Wrights Branch in a northwesterly direction. A transect
was then walked from the northwest in a southeasterly direction back toward Palmers Mill Road
through the wetland community. Dominant and codominant species were recorded as well as
observations regarding forest structure.

4. Findings
Database Review and Landscape Level Assessment
U.S. Fish and Wildlife Information for Planning and Conservation (IPaC) tool
The U.S. Fish and Wildlife Information for Planning and Conservation (IPaC) tool identified only one
wildlife species, the Delmarva Peninsula Fox Squirrel, as protected by the Endangered Species Act with
the potential to occur on site. Shortly thereafter, the Delmarva Peninsula Fox Squirrel was delisted from
federal protection on November 16, 2015. A plant species, Swamp Pink, is also protected by the
Endangered Species Act, and has potential to grow in Maryland’s Coastal Plain.
The IPaC tool also identified numerous birds of conservation concern protected by the Migratory Bird
Treaty Act that could potentially occur in the project area. These species are listed in IPaC Trust
Resource Report in the Appendix. These are migratory birds that are protected by the Migratory Bird
Treaty Act, which requires analyzing potential impacts and implementing appropriate conservation
measures for all project activities.
Maryland’s Environmental Resources and Land Information Network (MERLIN)
MERLIN was reviewed and there were no records of any sensitive species occurring on the site.
Sensitive species considered by MERLIN include rare, threatened and endangered species both federally
and state listed species.
Maryland Amphibian and Reptile Atlas (MARA) Database
The Maryland Amphibian and Reptile Atlas is a five-year joint project of the Natural History Society of
Maryland and the Maryland Department of Natural Resources. The goal of the project is to document
the current distributions of Maryland’s amphibian and reptile species. The MARA database was
reviewed to determine what species have the potential to occur on the site. The list of species reported
in the Rhodesdale quadrangle (the quadrangle of the project site) is included in the Appendix. None of
the species on the MARA list with potential to occur on the site is listed as state or federally threatened
or endangered.
USGS Maryland/DC Breeding Bird Atlas Project (BBA)
The results of the Maryland and DC Breeding Bird Atlas Project for 2002-2006 were reviewed for the
project site. The site is located in the northwest quadrant of the Rhodesdale quadrangle. A list of the
species is provided in the Appendix. No federally or state listed bird species appear on the list.
However, the prairie warbler and the wood thrush do appear on the list and these birds are listed as
birds on conservation concern by the USFWS as part of the Migratory Bird Treaty Act.

Maryland Department of Natural Resources Wildlife and Heritage Service List of Rare, Threatened and
Endangered Species of Dorchester County (April 2010)
The Maryland Department of Natural Resources Wildlife and Heritage Service List of Rare, Threatened
and Endangered Species of Dorchester County (April 2010) is included in the Appendix. A review of the
MERLIN database does not show any records for any of these species on the project site.
Site Characterization and Analysis (Tier 2 of USFWS Guidelines)
The entire site consists of 143.3 acres. Approximately 124 (87%) acres are in use as tilled agricultural
fields for corn and soybeans and approximately 19 (13%) acres are in natural vegetation along Wrights
Branch, a tributary of Marshyhope Creek.
The natural vegetation on the site consists of two vegetative communities. One community is an
uneven-aged, mature mixed hardwood forest that slopes down to Wrights Branch. Dominant trees are
approximately 16 inches in diameter. Dominant species include sweetgum, southern red oak, and
mockernut hickory. Understory and shrub layer species include American holly, mountain laurel,
greenbrier and poison ivy. The understory and shrub layer are moderately dense. The second
community is a wetland area that occurs at the base of the slope immediately adjacent to Wrights
Branch. Dominant tree species include red maple, sweetgum, blackgum, American holly, and sweetbay.
Shrub and perennial species include sensitive fern, royal fern, cinnamon fern, sweet pepperbush, lizard
tail, and clearweed.
FEDERALLY LISTED SPECIES
Based on the site characterization and review of the database information, the following species listed
as federally threatened or endangered have the potential to occur in Dorchester County:
Swamp Pink (Helonias bullata)
Description and Habitat
Swamp pink is a perennial of the lily family. It occurs in acidic wetlands from New Jersey south to
Georgia. The swamp pink can grow only in wetlands with perennially saturated – but not flooded – soils.
This dependence on an uncommon habitat type restricts the plant to small, scattered populations
throughout its range. The swamp pink grows in forested wetlands of Maryland’s coastal plain. In April,
its bright pink flowers bloom among the emerging skunk cabbage leaves. Four populations are currently
known, two in Cecil County and two in Anne Arundel County. It was classified as an Endangered Species
by the State of Maryland in 1987. (MD DNR 2015).
Analysis
The soils in the wetlands on site are frequently flooded and therefore suitable habitat for swamp pink
does not occur on the project site. Furthermore, the MERLIN database does not show any sensitive
habitats occurring on the project site.

Other Federally Listed Species
Two other species listed as federally endangered appear on Maryland Department of Natural Resources
Wildlife and Heritage Service List of Rare, Threatened and Endangered Species of Dorchester County
(April 2010). These two species are the American Burying Beetle (Nicrophorus americanus) and the Red-
cockaded Woodpecker (Picoides borealis). However, both of these species are noted as Endangered
Extirpated in Maryland, which means that it was once a viable component of the flora or fauna of the
state but for which no naturally occurring populations are known to exist in the state.
MIGRATORY BIRD TREATY ACT
The following birds are listed as birds of conservation concern and appear on the USGS Maryland/DC
Breeding Bird Atlas Project (BBA) for the northwest quadrant of the Rhodesdale quadrangle where the
project site is located.
Prairie Warbler (Dendroica discolor): The prairie warbler occurs in brushy slashings, bushy pastures,
and low pines. It breeds in dry, old clearings, edges of forest, and sandy pine barrens with undergrowth
of scrub oaks, especially on ends of slopes and ridges. The prairie warbler likes thick second-growth of
hickory, dogwood, hazel, or laurel with blackberry vines.
The forested areas and the edge of the forested areas on the site provide suitable habitat for the prairie
warbler for breeding. This species was also identified on the breeding bird atlas in this quadrant of the
Rhodesdale quadrangle as being observed with probable breeding evidence of territorial behavior. The
species is considered a Bird of Conservation Concern by the US Fish and Wildlife Service. The prairie
warbler is not listed on the current list of rare, threatened and endangered species in Maryland.
Wood Thrush (Hylocichla mustelina): The Wood Thrush breeds in deciduous and mixed forests in the
eastern U.S. where there are large trees, moderate understory, shade, and abundant leaf litter for
foraging. They winter in lowland tropical forests in Central America. Suitable habitat for the wood
thrush occurs on the project site in the forested areas along Wrights Branch. The species is considered a
Bird of Conservation Concern by the US Fish and Wildlife Service. The wood thrush is not listed on the
current list of rare, threatened and endangered species in Maryland.
STATE LISTED SPECIES
Delmarva Peninsula Fox Squirrel (Sciurus niger cinereus):
Description, Habitat and Behavior
The largest of all the tree squirrels, the Delmarva Peninsula fox squirrel has silver to whitish-gray slate
hair and an unusually full, fluffy tail and white belly. The squirrel’s coat varies in color from frosty silver-
gray to almost black. The Delmarva fox squirrel lives in mature forests of mixed hardwoods and pines
with a closed canopy and open understory. A habitat suitability model indicated that sites were fox
squirrels were present had a higher percentage of large trees (>12 inches in diameter), a lower
percentage of shrub groundcover, and a slightly lower understory density than did sites where squirrels

were not found. Although it is a forest animal, the squirrel spends considerable time on the ground
foraging for food, typically in woodlots of mixed loblolly pine and hardwoods such as oak, maple,
hickory, walnut, and beech— trees that provide food including nuts and seeds. The squirrel will also
take food from farm fields. Feeding on tree buds and flowers during the spring, the squirrel will also eat
fungi, insects, fruit, and seeds. In the summer and early fall, the squirrel forages on mature, green pine
cones. The animal generally lives in woodlands associated with farmland areas—not typically in
suburban settings. Less agile than the common gray squirrel, the Delmarva fox squirrel often ambles
along the forest floor rather than leaping from branch to branch. The animal usually avoids
confrontations by running away rather than climbing a tree but will do so to avoid a predator. The fox
squirrel is also quieter than the gray squirrel. The home range of the fox squirrel varies, but averages
about 40 acres. The Delmarva fox squirrel prefers to nest in tree cavities but will also nest on a tree
crotch, in tangles of vines in tree trunks or at the end of large tree branches. Squirrels mate in late
winter and early spring. About 44 days later in February and March as many as four young are born.
Females may give birth to two litters per year. They raise the young by themselves for about three
months (USFWS, 2008).
On November 16, 2015, the U.S. Fish and Wildlife Service issued a final rule removing the Delmarva fox
squirrel from the list of endangered and threatened species. Following its 2012 review of the species,
the USFWS concluded that the best available scientific and commercial data indicate the Delmarva fox
squirrel is no longer in danger of extinction or likely to become endangered within the foreseeable
future. However, the Maryland Department of Natural Resources Wildlife and Heritage Service will
continue to protect the Delmarva fox squirrel and its habitat as a state threatened species (Lori, Byrne,
MD DNR WHS, personal communication to Noreen Davis, Nov 2015).
Analysis
The project site contains 19 acres of hardwood forest. There is a fairly dense shrub layer and dense
understory making the site unsuitable for the Delmarva fox squirrel. This is consistent with the MERLIN
database, which does not show that the site contains habitat for the Delmarva fox squirrel.
