Site: Mills Canyon Wilderness Area, Burlingame, CA
Dear Mr. Disco,
At your request, during the week of October 14, 2007, I visited the above site for the
purpose of inspecting and commenting on a percentage of the Coast live oak trees in the
Mills Canyon Wilderness Area. Sudden Oak Death has been recently documented on the
property and the spread of the disease is of concern. My report includes a spreadsheet
with the trees that were inspected, along with recommendations for controlling the
sudden oak death disease and disposing of the infected trees.
Method:
The trees surveyed on this site were located on a map provided by you. Due to the
rugged terrain of the park, a Global Positioning System was used to locate several of the
locations in the park. A random sampling of the total number of trees was included in
this report. Each tree was assigned an identification number. The identification number
was embossed on a metal foil tag and nailed to the tree at eye level. Where possible, the
trees were measured for diameter at 54" above ground level (DBH or diameter at breast
height). Each tree was assigned a condition rating for form and vitality using the
following scale:
1 -
29
Very Poor
30
- 49
Poor
50
- 69
Fair
70
- 89
Good
90
- 100
Excellent
The height of each tree was estimated and the spread was paced off. Oaks symptomatic
of sudden oak death were noted. Each of the following symptoms: bleeding canker, oak
bark beetle, Hypoxylon fungus and foliar desiccation were categorized. The location of
the nearest bay tree was noted. Lastly, a comments section is provided.
,Mills Canyon Project, Burlingame, CA October 14, 2007
Site:
�-- Mills canyon is a unique wildlife area. The park is a haven for native mammals, birds,
reptiles and insects. The three dominant species of trees to the canyon are Coast live oak
(Quercus agrifolia), California bay (Umbellularia californica) and the California
.. buckeye (Aesculus californica). The introduction of Coast redwood, Monterey pine and
Bailey acacia has affected surrounding natives. The non -natives are rapid growing trees
•� that tend to compete with the native trees.
The canyon consists of a large riparian area in the lower creek bank. In these locations
the foliage is thick with full canopy cover. Bays, Live oaks and Buckeyes are mixed in
�-
the lower terrain near the creek. Grassland ridged areas where moisture levels are lower
,.,
and tree spacing is greater, are populated by live oaks, bays and the imported trees. This
savanna type terrain has larger tree spacing. Here the trees are more than one canopy
~
spread apart. Large rock outcroppings throughout the park are a geological reminder of
the truly native nature of the area.
In recent years, the City of Burlingame, the county of San Mateo, and volunteer groups
have helped to return the canyon to its natural environment. Throughout the canyon are
reminders of the years before the canyon was protected. An extensive trail system is well
`-
maintained which has aided in the survey of the property.
Observations:
�..
From the La Mesa Court gate, the symptomatic trees are easily visible. The trail and the
�..
paved access road reach the canyon floor rapidly. In this area the bays, live oaks and
buckeyes are crowded near the creek bank. Near the floor of the canyon and the lower
..r
elevations the disease is quite prevalent. The disease also has spread to the southern and
eastern ridges and throughout the neighboring private properties.
On the northern and western ridges the disease is less wide spread. Tree spacing is
�., greater in this location and the bay population is lower compared to the damp creek area.
Isolated infected areas are located on these ridges. Several species of exotics (imported
trees) have been planted or have spread to this area. The upper ridges have been used as
�.. a dump site in past years. Debris buildup is not advisable on the root zones of the oaks.
Discussion of Sudden Oak Death:
Sudden oak death is a forest disease which has infected trees in 14 counties in California
'-' and Oregon. As early as 1996, the first sightings of sudden oak death of Tan oaks
�.. (Lithocarpus densiflorus) and Coast live oaks (Quercus agrifolia) in Marin County was
reported. In the year 2001, the infection was located on a site in San Mateo County on a
Black oak in the Long Ridge Open Space preserve. The disease commonly called sudden
oak death is caused by a pathogen, Phythopthera ramorium isolated in 2001 (Garbelotto;
�.- Rizzo).

(brownish in color)
Sudden oak death has been found on over 100 plant species and is responsible for the
infection or death of tens of thousands of oak trees. The disease is particularly
devastating in the oak, bay woodland. The disease sporulates on the leaves of the
bay tree, causing leaf burn and splotching.
The spotting or burning of the bay leaf often
has a halo look to the spot. The native bay
is considered an infectious host. The
location of bay trees in relationship to the
live oaks is the most critical factor in
evaluating the risk of a live oak being
infected by the disease. The airborne
disease is spread from leaves of the bay to
roots and trunks of the terminal host the
coast live oak. The coast live oak is often
infected during the mild warm moist season
(spring).
The California Bay is an infectious host

Bleeding Cankers on the trunk of live oak in canyon
Cankers on roots and the trunk eventually girdle the oaks. It is believed that infected
oaks can live for up to 2 years after being girdled by the cankers.
Control Recommendations:
At this time there are no control measures that will eradicate this disease. Steps can be
taken to help prevent the infection of valuable trees. Recommended steps are as follows:
♦ Identify specimens that are of an importance to the site and are worth saving.
♦ Remove the infectious host (bay trees, camellias and Rhododendron spp) to a
radius of 30 feet. Remove the lower branches of redwoods.
♦ Apply a basal spray of phosphites and bark penetrant (surfactant).
♦ Reduce foot traffic and restrict work in infected areas during the wet season.
♦ Establish ordinances, recommendations for tree work that does not spread the
disease is mandated.
Currently there is 1 brand of phosphite and 1 brand of bark penetrant registered on an
emergency registration for this purpose. The mixed chemicals should be sprayed or
injected on the root flare and trunk of the desired tree. Excess moss should be removed
from the trunk with the use of a scraping device (hoe or trowel.). Recommended times of

application is in the mid to late fall and in the spring when nutrient intake is optimal. The
`- phosphite is systemic and stimulates the trees defense system, resulting in improved
resistance to the disease. Annual applications of the phosphite are recommended. The
black oaks being deciduous should be sprayed in the spring only as a fall application may
.. not be effective.
Arborist Robert Weatherill applying systemic fungicide in October of 2007
Recommendations for this Site:
♦ Remove infectious hosts around landmark trees or stands of trees (Picnic rock,
oak #183, etc.).
♦ Spray trunks and root flares of trees not infected or with smallish cankers with
a systemic fungicide.
♦ Prohibit the tracking of soil from infected site during wet season, by closing
park or fencing off areas under and around infected trees.
♦ Signage at the entrances and exists of the park in an effort to explain the
severity of the situation and to also educate on the prevention of spreading the
infected soil.
♦ Cleaning stations at these locations to help reduce the spread of the disease via
foot traffic, etc.
♦ Allow work on trees to be preformed only in the dry season. All foliage and
wood should be left on site in the form of wood chips and fire wood. Wood

chips should be spread and allowed to dry. Wood that cannot be chipped
should be used as firewood. At this location, attempts to chip all wood should
�., be considered. No wood is to be hauled off site for sale or residents' use.
Equipment should be cleaned prior to leaving the site. Dirt should be washed
from tires and frames of vehicles. Tools should be sterilized with Lysol or a
10 percent bleach solution.
... ♦ Monitor the progress of the disease by surveying the trees annually. The data
will help to analyze the effects of the preventive spray.
�.. Summary of Data:
261 trees were surveyed, 65 trees, roughly 25%, were symptomatic of sudden oak death.
The bulk of the trees surveyed were located on the floor of the canyon. Tree infection in
the floor of the canyon was significant with 30% (55 infected trees of 181 total trees) of
the oaks surveyed being symptomatic of the disease. In the western ridge area 80 trees
were surveyed 6 trees were infected 8 percent. As documented in several publications
`. the presence of the bay trees is directly related to infection of the oaks.
Summary:
The spread of sudden oak death is a growing reality for the communities that border the
highway 280 corridor. Private landowners and municipalities are in an alarmed state.
Nearly every community has sponsored workshops to educate the residents and
professionals in the management of
this pathogen. The disease was
discovered and identified on the East
side of highway 280 in June of 2006
(Kielty). The June discovery was the
first documented site east of 280.
This disease will soon change the
native landscape of California. As
the disease spreads through the
counties of western California the
Coast live oak may no longer be the
areas dominant tree. At this point no
"resistant species" of live oaks have
been propagated. The research hours
devoted to this pathogen may one
day develop a control of the disease.
Until a control is developed
preventive measures are the only

prolific. Removal of all the bays on the site is not an option. Cost and environmental
damage would hinder this method. Removal of smaller bays around landmark trees is a
a.� viable option. Dead trees should be removed to reduce the fire hazard. Sudden oak death
