A1.0 Introduction<br />
HydroGeoLogic, Inc. (HGL) is executing a groundwater remediation project at Operable<br />
Unit (OU)-1 at the former Fort Ord U.S. Army Base located in Monterey County,<br />
California. This work was awarded in December 2003 by the U.S. Army Corps of<br />
Engineers (USACE)-Sacramento District under Contract Number DACA45-03-D-0029;<br />
it is being administered by the USACE-Sacramento District.<br />
Fort Ord was established in 1917 as a military training base for infantry troops. In<br />
January 1991, the Secretary of Defense announced the downsizing/closure of the base. In<br />
August 1994, portions of the property were transferred to the University of California and<br />
the FONR was established in June 1996. The former Fort Ord is located near Monterey<br />
Bay approximately 80 miles south of San Francisco (Figure A1.1). The base consists of<br />
approximately 28,000 acres near the cities of Seaside, Sand City, Monterey, Del Rey<br />
Oaks, and Marina. Monterey Bay marks the western boundary, Toro Regional Park<br />
borders the base to the southeast and land use east is primarily agricultural.<br />
Activities conducted at the former Fort Ord Fritzsche Army Airfield Fire Drill Area<br />
(FDA) (i.e., OU-1) between 1962 and 1985 resulted in the release of contaminants to<br />
soils and groundwater. Although 10 separate volatile organic compounds (VOCs) were<br />
identified as contaminants of concern in groundwater underlying OU-1, trichloroethene<br />
(TCE) is the contaminant that was detected at the highest concentrations and across the<br />
greatest extent of the affected aquifer. A groundwater extraction and treatment system<br />
(GWETS) was constructed in 1988 to remediate TCE and other groundwater<br />
contaminants.<br />
The components of the remediation project include wells, pipelines, infiltration trenches,<br />
and treatment facilities (Figure A1.2). A key factor affecting the design and<br />
implementation of the groundwater cleanup is the fact the groundwater plume lies<br />
beneath a part of the University of California Natural Reserve System (UCNRS)<br />
designated as the Fort Ord Natural Reserve (FONR). The FONR area potentially<br />
impacted by the construction of OU-1 remediation facilities is approximately 130 acres.<br />
Therefore, the project has the additional constraint that activities undertaken to achieve<br />
the OU-1 cleanup adequately protect and maintain the special-status species found within<br />
the FONR, specifically two federally listed plant species, Monterey spineflower<br />
(Chorizanthe pungens var. pungens) and sand gilia (Gilia tenuiflora ssp. arenaria).<br />
OU-1 occupies a portion of the FONR in the southwestern corner of the former Fritzsche<br />
Army Airfield, west of Imjin Road and north of Reservation Road. The remediation<br />
project illustrated in Figure A1.2 is designed to avoid, mitigate, or minimize<br />
environmental impacts in the OU-1 area. To that end, the locations, extent, and<br />
populations of sand gilia and Monterey spineflower that are present in the footprint of<br />
proposed construction activities were identified through a rare plant survey conducted at<br />
specified sites.<br />
1
A1.1 Survey Objectives<br />
The objectives of the <strong>2008</strong> rare plant survey were to: 1) identify locations and estimate<br />
rare plant populations at each designated site for Monterey spineflower and sand gilia;<br />
and 2) to map Monterey spineflower and sand gilia populations so that future activities<br />
could avoid or reduce impacts to those populations. A total of 5 sites, including 15 well<br />
locations were surveyed for the presence of rare plants (Figure A1.3).<br />
A1.2 Site Location and Description<br />
The dominant habitats in this area include coast live oak woodland, maritime chaparral,<br />
coastal scrub, and annual grassland. Several special-status plant and wildlife species<br />
occur within the FONR, including sand gilia and Monterey spineflower. The northern<br />
and eastern boundary of OU-1 is adjacent to a large expanse of non-native grassland.<br />
Transmission of non-native grass species into OU-1 is accelerated by the prevailing<br />
winds, which blow seeds south and into the OU-1 area (Fusari 2004). Non-native grasses<br />
and weedy forbs are already present throughout much of the OU-1 area. The spread of<br />
non-native, invasive species into newly disturbed areas might result in population<br />
declines of Monterey spineflower and, especially, sand gilia, which is less tolerant of<br />
plant cover than Monterey spineflower.<br />
A1.1.1 Sand Gilia<br />
Sand gilia is a small annual in the phlox family (Polemonaceae). Plants range in height<br />
from two to six inches with a small, basal rosette of leaves. The lower branches of the<br />
stem are generally densely glandular. Plants typically bloom from April through June<br />
and have funnel-shaped flowers with narrow, purple to pinkish petal lobes and a purple<br />
throat. This species occurs in open sandy soils in dune scrub, coastal sage scrub, and<br />
maritime chaparral habitats. Sand gilia is endemic to Monterey Bay and the peninsular<br />
dune complexes. A search of the California Natural Diversity Database (CNDDB)<br />
revealed that there are 28 occurrences within Monterey County, including the<br />
occurrences at Fort Ord (CDFG <strong>2008</strong>). It is likely that some of these occurrences are no<br />
longer present and the exact number of extant (still in existence) occurrences are<br />
unknown.<br />
A1.1.2 Monterey Spineflower<br />
Monterey spineflower is a small, prostrate annual in the buckwheat family<br />
(Polygonaceae) that blooms from April to June. The white to rose floral tube of<br />
Monterey spineflower distinguishes it from the more common, but closely related diffuse<br />
spineflower (Chorizanthe diffusa), which has a lemon-yellow floral tube. This species<br />
typically occurs on open sandy or gravelly soils in coastal dune, coastal scrub, and<br />
maritime chaparral habitats. There are 24 records of Monterey spineflower within<br />
Monterey County in the CNDDB (CDFG <strong>2008</strong>); however, it is not known how many of<br />
these are extant.<br />

A2.0 Methods<br />
The survey area consisted of selected well sites and discrete segments of the existing<br />
roads within OU-1. The well sites surveyed are located either adjacent to the roadway or<br />
at the terminus of access paths constructed to reach the well site. A total of 5 sites and 15<br />
wells were identified for surveys. Figure A1.3 shows the survey sites. The areas were<br />
surveyed for rare plants Monterey spineflower and sand gilia completely on one survey<br />
effort conducted on May 5, <strong>2008</strong>.<br />
A2.1 Rare Plant Surveys<br />
The survey for sand gilia and Monterey spineflower was conducted by a DD&A biologist<br />
and a DD&A GPS technician on May 5, <strong>2008</strong>. The peak blooming period, late April -<br />
early May <strong>2008</strong>, was determined by observing a known occurrence of sand gilia in the<br />
vicinity of FONR. The rare plant survey area included the sites and staging areas shown<br />
in Figure A1.3.<br />
The survey was conducted along existing roadways/access routes. In the absence of rare<br />
plants, the width of the survey area was approximately 10 feet beyond the edge of the<br />
roadway on either side. If a rare plant was identified, the survey in that area was<br />
extended to the boundary of the population encountered.<br />
Mapping of rare plant species was done using a Trimble Pathfinder ProXH GPS unit with<br />
an additional Zephyr antenna system to boost reliability and accuracy of GPS data<br />
collection. Large areas of Monterey spineflower and sand gilia were mapped as<br />
polygons; smaller groups and individuals were mapped as points with attributes to<br />
identify the number of individuals at each location.<br />
Individual counts were made for all sand gilia populations whether they were mapped<br />
using points (population < 10) or polygons (population ≥ 10). However, Monterey<br />
spineflower were only counted as individuals when groups of less than five were mapped.<br />
Monterey spineflower mapped as polygons were characterized according to the percent<br />
of cover. The categories ranged from Very Sparse (corresponding to an absolute cover of<br />
less than 3 percent), Sparse (3-25 percent), Medium Low (26-50 percent), Medium (51-<br />
76 percent), and Medium High (76-97 percent) to Very High (>97-100 percent). GPS<br />
data was exported to shapefile format for use in a Geographic Information System (ESRI<br />
ArcGIS) and mapped on high resolution aerial photography. These maps are represented<br />
in Figures A3.1 and A3.2.<br />

A3.0 Results and Discussion<br />
A3.1 Rare Plant Survey Results<br />
A3.1.1 Sand Gilia<br />
Sand gilia was not observed or mapped in any of the locations within the 5 survey areas<br />
and 15 well sites surveyed for rare plants.<br />
A3.1.2 Monterey Spineflower<br />
A total of 52 populations (19 polygons and 33 points) of Monterey spineflower were<br />
mapped along the 5 rare plant survey areas, and 15 well sites within FONR (Table A3.1<br />
and Figures A3.1 and A3.2). A total of 56 individual plants were identified at the 33<br />
mapped GIS points. Because population size estimates are not as easily quantified as the<br />
sand gilia populations, individual Monterey spineflower plants were not counted within<br />
the GIS polygons. As mentioned in the methods section of this document, populations of<br />
Monterey spineflower were given a percentage of cover using visual estimation. Of the<br />
19 populations of Monterey spineflower that were mapped as polygons, two populations<br />
had a Medium cover class (51-76 percent cover), five populations had a Medium Low<br />
cover class (26-50 percent), 11 populations had a Sparse cover class (3-25 percent), and<br />
one population had a Very Sparse cover class (
Coast Live Oak Woodland<br />
Coast live oak woodland within the FONR is characterized by a mosaic of coast live oak<br />
trees (Quercus agrifolia), intermixed with chaparral, grassy and sandy openings. The oak<br />
woodland within the FONR ranges from high canopy cover to low canopy cover. The<br />
areas with high canopy cover generally do not permit the existence of shrubs in the<br />
understory, and, therefore, the understory is limited to poison oak and the common<br />
annual grasses, such as rip-gut brome, wild oat, and annual fescue. In areas with a low to<br />
moderate canopy cover, the oak woodland is intermixed with chaparral shrub species<br />
such as California sagebrush (Artemisia californica), coyote brush (Baccharis pilularis),<br />
shaggy bark manzanita (Arctostaphylos tomentosa ssp. tomentosa), and sandmat<br />
manzanita. Common herbaceous species in these areas include native species such as<br />
miner’s lettuce (Claytonia perfoliata), and non-native species such as rip-gut brome, and<br />
rattail fescue.<br />
Grassy openings in the woodland habitat contain scattered coast live oak trees and shrubs<br />
with dense growth of annual grasses such as rip-gut brome, annual fescue, red brome, and<br />
wild oat. Open, sandy areas within coast live oak woodland can support special-status<br />
species such as Monterey spineflower and sand gilia. Coast live oak woodland is<br />
widespread throughout the FONR property, and was observed at or surrounding all sites<br />
surveyed.<br />
Central Maritime Chaparral<br />
Central maritime chaparral habitat within the FONR is dominated by hard-leaved shrubs<br />
such as shaggy bark manzanita, sandmat manzanita, and Monterey manzanita. Other<br />
shrubs that are common throughout this habitat types include coyote brush and California<br />
sagebrush. In areas where soils maintain a higher moisture content, poison oak can also<br />
be a dominant species in the maritime chaparral. The central maritime chaparral on<br />
FONR is often mixed with coast live oak trees and several annual grass species including<br />
rip-gut brome, red brome, and rattail fescue.<br />
Coastal Scrub<br />
Coastal scrub occurs near the coast on sandy soils and on inland hills with shallow top<br />
soils. Within the FONR, this habitat type is characterized by sparse to dense cover of<br />
soft-leaved, low stature shrubs about three to seven feet in height, such as coyote brush,<br />
California sagebrush, sticky monkey flower (Mimulus aurantiacus), poison oak, mock<br />
heather (Ericameria ericoides), and black sage (Salvia mellifera). The herbaceous layer<br />
in the coastal scrub is sparse where shrub cover is dense but is more developed in areas<br />
where there is less shrub cover. Species typically occurring in this layer include<br />
Monterey spineflower, sand mat, and everlasting (Gnaphalium sp.).<br />
Annual Grasslands<br />
The annual grassland habitat is characterized by a dense cover of rip-gut brome with<br />
other non-native annual grasses such as wild oat, soft chess, Italian ryegrass (Lolium<br />
multiflorum), and rattail fescue. Other species that are common in the annual grassland<br />
habitat include sky lupine (Lupinus nanus), a native species, and weedy forbs (non-native<br />
plants that are not woody and are not grasses), such as filaree (Erodium sp.) and cat’s ears<br />
5
(Hypochaeris sp.). Cat’s ears is a non-native, invasive species of particular concern to<br />
the UC staff managing the FONR. Shrubs species, such as coyote brush, California<br />
sagebrush, and coffee berry (Rhamnus californica), occur scattered throughout the annual<br />
grassland.<br />
Disturbed/Developed<br />
The disturbed habitat is characterized by the roadways and staging areas currently and<br />
historically in use on the FONR property. Most disturbed areas are dominated by bare<br />
ground and non-native grasses, such as wild oat, rip-gut brome, and red brome. All of the<br />
sites surveyed contained disturbed/developed habitat in the forms of trails and/or roads.<br />
A4.0 Conclusions<br />
Monterey spineflower populations were observed in more locations than sand gilia<br />
populations (52 locations versus zero locations of sand gilia). DD&A conducted rare<br />
plant surveys from 2006-<strong>2008</strong> within the FONR OU-1 property, and the <strong>2008</strong> rare plant<br />
survey was the first year sand gilia was not observed within any of the areas surveyed.<br />
There are several possible reasons for the apparent decline in sand gilia populations.<br />
Sand gilia had previously been observed in only two of these surveys areas in the<br />
previous two years. Also sand gilia populations at DD&A reference sites were relatively<br />
low indicating that the conditions during sand gilia growing season were not optimal.<br />
Relatively abundant Monterey spineflower populations do not seem as equally affected<br />
by the same constraints as sand gilia. Previous rare plant surveys conducted by DD&A<br />
also indicate that populations of Monterey spineflower were often observed in areas with<br />
sparse to moderately abundant non-native annual grass cover, suggesting that this species<br />
may be somewhat more tolerant of annual grass cover than sand gilia.<br />
A5.0 Comparisons 2007-<strong>2008</strong><br />
Sand gilia populations decreased significantly from last year (12 locations in 2007<br />
compared to zero locations in <strong>2008</strong>); however, the amount of surveyed locations also<br />
decreased from the rare plant survey last year (15 sites in 2007 compared to 5 sites in<br />
<strong>2008</strong>). Of the five sites that were surveyed during the <strong>2008</strong> rare plant survey, sand gilia<br />
previously had been observed at Sites 6 and 9 during the 2006 survey.<br />
Monterey spineflower populations have increased compared to the 2007 rare plant<br />
survey. Both years generally had the same number of populations (54 populations in<br />
2007 and 52 in <strong>2008</strong>) and densities (the majority of the populations ranged from sparse to<br />
very sparse densities in 2007 and <strong>2008</strong>). However, the survey area was greatly<br />
diminished from 2007 to <strong>2008</strong>. In <strong>2008</strong>, Monterey spineflower polygons were observed<br />
increasing in size. Sites 4, 6, 11, and 8 have all increased in area from 2007 to <strong>2008</strong>. In<br />
Site 9, the only site that did not show an increase in area, the polygons observed<br />
increased in density (one Medium-Low polygon in 2007 compared to one Sparse, two<br />
Medium, and three Medium-Low polygons in <strong>2008</strong>).<br />
