Box 6187 San Mateo, CA 94403 650-525-1464 October 29, 2007 Bob Disco Burlingame Parks and Recreation 850 Burlingame Avenue Burlingame, CA 94010 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). .r KIELTY ARBORIST SERVICES P.O.Box 6187, San Mateo, CA 94403 • TEL: (650) 525-1464 • FAX: (650) 525-1439 �-' Kkarbor0476?_yahoo.com -2- N%W Mills Canyon Project, Burlingame, CA October 14, 2007 Mills Canyon as seen from tree #183, note the dead trees in photo (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 ...

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.).

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 KIELTY ARBORIST SERVICES P.O.Box 6187, San Mateo, CA 94403 • TEL.

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 Grant Joo Field- Biologist, sampling symptomatic oak �- choice. On this site the disease is primarily in the moist creek area were the bays are 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.
