Re: Mazama Pocket Gopher Survey
9548 Killion Road Southeast, Yelm, WA 98597
Dear Mr. Dobler,
Soundview Consultants LLC (SVC) conducted a Mazama pocket gopher (MPG) survey on an
approximately 2.43-acre property located at 9548 Killion Road Southeast in the City of Yelm,
Washington (Figure 1). The subject property consists of one parcel located in the Northeast ¼ of
Section 24, Township 17 North, Range 01 East, W.M. (Thurston County Tax Parcel Number
21724130100). SVC performed formal MPG surveys to identify potential presence of MPG (Thomomys
mazama) on the subject property. This MPG survey was conducted to support potential future
commercial development on the subject property.

Background Data
Prior to the site investigation, SVC staff conducted background research using Thurston County
Geographic Information System (GIS) data, Washington Department of Fish and Wildlife (WDFW)
Priority Habitat and Species (PHS) maps, Natural Resources Conservation Service (NRCS) soil survey,
and U.S. Geological survey topographic maps (Attachment A).
The NRCS soils map (Attachment A1) identifies one soil type on the subject property: Spanaway
gravelly sandy loam, 0 to 3 percent slopes (110), which is a “more preferred” soil type for MPG (City
of Yelm, n.d.). Additionally, the Thurston County Habitat Conservation Plan map shows areas
northwest-adjacent to the subject property as occupied by MPG; the subject property is classified as
“near” to MPG-occupied areas on this map (Attachment A2). The WDFW PHS map (Attachment
A3) does not identify MPG presence on the subject property, though an offsite MPG occurrence is
mapped approximately 415 feet northwest of the subject property. The topography on the subject
property is relatively flat with a slight slope towards the west of the property. Onsite elevations range
from approximately 350 feet to 346 feet above mean sea level (Attachment A4); the site topography
is well below the 40 percent slope threshold for limiting MPG presence.
Mazama Pocket Gopher Habitat Requirements
MPG primary habitat includes open meadows, prairie, and/or grassland areas with friable, well-
drained soils that are not too rocky (Maser et al., 1981; Stinson, 2005). The majority of sites with
pocket gophers generally have friable, loamy, deep soils with less than 15 percent slopes and less than
10 percent by weight of medium sized rocks (Steinberg and Heller, 1997). Roads, inhospitable soil
types or substrates, development, and buildings present impermeable barriers to MPG movement and
dispersal (USFWS, 2014). MPG do not require high quality prairie systems but utilize a wide range of
grassland environments that may sometimes be in close proximity to moderate- and high-intensity
land uses (Stinson, 2005). MPG forage requirements include an assortment of plant material including
leafy vegetation, succulent roots, shoots, and tubers such as clover (Trifolium spp.), lupine (Lupinus
spp.), false dandelions (presumably Hypochaeris radicata), and grasses, with a preference towards plant
species with bulbs such as wild onion and wild garlic (Maser et al., 1981; Stinson, 2005).
Methods
Four subspecies of the Mazama pocket gopher found in Thurston and Pierce counties were listed in
2014 by the United States Fish and Wildlife Service (USFWS) as threatened under the federal
Endangered Species Act (ESA) of 1973. The Olympia pocket gopher (Thomomys mazama pugetensis),
Tenino pocket gopher (Thomomys mazama tumuli), and Yelm pocket gopher (Thomomys mazama yelmensis)
are three subspecies of MPG that occur in Thurston County, while the Roy Prairie pocket gopher
(Thomomys mazama glacialis) occurs in Pierce County. Of the four subspecies, only the Yelm pocket
gopher’s range is mapped onsite. These MPG subspecies are regulated locally under Yelm Municipal
Code (YMC) 18.21.110 (Fish and Wildlife Habitat Conservation Areas) and subject to restricted
uses/activities under the same title.
Formal surveys were performed by a USFWS-trained MPG survey biologist on September 21, 2023
(Visit 1) and October 24, 2023 (Visit 2). The surveys followed the City of Yelm’s Protocol and Procedure
for MPG inspections in the City (City of Yelm, n.d.), and the objective of the surveys was to document
the presence of any burrowing rodent mounds constructed by MPG or native mole species such as
1690.0007 Killion Road SW 3 Soundview Consultants LLC
Mazama Pocket Gopher Survey October 26, 2023
the Townsend mole (Scapanus townsendii) or Pacific mole (Scapanus orarius). The investigations included
walk-through assessments of the entire subject property to determine onsite habitat conditions. Based
on desktop aerial photograph review and the onsite habitat assessment, a MPG Survey Area for
walking transects was established. Forested areas with greater than 30% tree canopy were assessed but
excluded from the MPG Survey Area.
Within the MPG Survey Area the onsite MPG survey consisted of walking evenly spaced, parallel
transects in a straight line less than five meters apart while scanning approximately two to three meters
on each side, looking for potential mounds. Each mound or grouping of mounds observed were
identified as either MPG or mole mound(s). Any positive MPG mounds or indeterminant mound
identifications were documented, photographed, and marked with a GPS unit. Two formal surveys
were conducted greater than 30 days apart within the required survey window (June 1 to October 31)
to determine MPG presence in conformance with the established City survey protocol.
Results
The 2.43-acre subject property is located in a mixed residential and commercial land use setting and
is currently undeveloped and dominantly forested apart from a section of field located in the southeast
section of the site. The subject property is bound by a senior living facility to the north, undeveloped
pastureland to the west, Killion Road Southeast to the east and West Yelm Avenue to the south. Soils
across the site are loose sandy gravelly soils. The MPG Survey Area is mostly located on the
southeastern portion of the site where vegetation consists predominantly of a field dominated by
Kentucky bluegrass (Poa pratensis) and tall fescue (Schedonorus arundinaceus) with minor presence of
western yarrow (Achillea millefolium) and non-native perennial peppercress (Lepidium latifolium),
houndstongue (Cynoglossum officinale), bull thistle (Cirsium vulgare), Queen Anne’s lace (Dacus carota), and
wild marjoram (Origanum vulgare). Forested areas in the northern and central portions of the site were
dominated by Douglas fir (Pseudotsuga menziesii) trees with approximate diameter-at-breast-heights
(dbh) of 6” to 24” and were surrounded by dense Himalayan blackberry (Rubus armeniacus).
Additionally, a couple scattered Douglas fir, cultivated apple trees (Malus spp.) and one lodgepole pine
(Pinus contorta) were identified within the southernmost corner of the site. The site provides poor
quality MPG foraging habitat due to a very low cover of forbs (less than 2 percent cover) for MPG to
forage on. Areas with higher forb density were observed near the eastern edge of the survey area but
had no presence of MPG mounds.
Following the City’s MPG inspection protocol, SVC did not positively identify MPG mounds on the
subject property. Multiple rodent mounds were identified during both site visits; however, none of the
identified mounds exhibited distinctive characteristics of active MPG presence (e.g. soft and sifted
soils, irregular mound shapes, and off-center entrance holes). Some of the mounds were determined
to be likely mole mounds due to high and circular mound shapes with large roots and gravels on top
of the pile. The remaining mounds were classified as indeterminant mounds that lacked distinctive
identification characteristics. These mounds consisted of soils that appear to have been previously
excavated by rodents but are currently vegetated with grasses. During Visit 2, none of the
indeterminant mounds had indicators of fresh use or excavation.
Refer to Attachment B for photographs of the typical habitat conditions and identified mounds onsite.

Conclusion
SVC conducted two formal site investigations surveying the subject property for the presence or
evidence of active MPG. Surveys followed the City of Yelm Protocol & Procedure for Mazama Pocket
Gopher Inspections in the City of Yelm (City of Yelm, n.d.). No MPG mounds were identified during the
site investigations. During both site investigations, several rodent mounds were identified and
classified as indeterminant or likely mole mounds. These mounds were either vegetated with
herbaceous vegetation or exhibited characteristics of mole mounds. Indeterminant mounds had no
indicators of fresh use or excavation during Visit 2. Additionally, the subject property was identified
as poor-quality MPG foraging habitat. Due to the lack of positive MPG mound determinations, lack
of evidence of fresh mound use, and poor-quality foraging habitat onsite, the site is not likely occupied
by active MPG.
