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 />
