GARBER PARK VEGETATION MANAGEMENT PROJECT FUNDED

The City of Oakland Wildfire Prevention Assessment District has approved funding for the Garber Park Fuel Reduction and Vegetation Management Project,  and implementation will begin soon.   LeRoy Griffin, City of Oakland Assistant Fire Marshall, will be the special guest at our next Workday, Tuesday, December 6, @ 10AM.  Following a discussion of the management plan we will walk with LeRoy around the Loop Trail and Claremont Avenue for a more detailed “in-the-field” look at this comprehensive fuel management plan.  This multi-year, year round project includes a botanist who will oversee and assist with appropriate and proper removal of invasive species, thus ensuring that environmentally sensitive techniques are used while managing vegetation to reduce the risk of a major fire. 
MEET at the Evergreen Lane Entrance to Garber Park @ 10AM. 

DIRECTIONS: The closest address is 144 Evergreen Lane. From Alvarado Rd, take Slater lane to Evergreen Lane, turn Right onto Evergreen Lane.

A SERIOUS CHALLENGE FOR GARBER PARK: SUDDEN OAK DEATH PATHOGEN IS PRESENT

On Oct 3 at a community meeting on the UC campus, Dr. Matteo Garbelotto reported the results of this spring’s “SOD Blitz” in the northern East Bay area. Altogether 383 samples of potentially infected Bay Laurel leaves, collected by trained “citizen scientists” in the north Berkeley/Claremont Ave/ upper UC Berkeley campus area, were analyzed by Dr. Garbelotto’s lab. 51 samples tested positive for the SOD pathogen. This level of infection was characterized by Dr. Garbelotto as PERVASIVE --sufficient among other things to cause doubt with respect to the apparently negative samples. (According to Dr. Garbelotto, the validity of a negative finding depends largely on how many nearby trees were also sampled as negative. If it looks like a duck and walks like a duck, unless there is a flock of ducks, it might be a chicken.).

Looking at Garber Park in particular, at least three samples tested positive, two of them from Bay Laurel trees situated in a threatening position with respect to our beautiful stand of heritage oaks.

In view of the experience of Dr. Garbelotto’s lab, the significance of a positive finding among the Bay Laurels is sobering. Once the Sudden Oak Death pathogen is present, it is endemic in the ecosystem. There is no sanitizing methodology. Drawing from the lab’s recent history in heavily infected areas of the south bay, in the next decade the north bay can expect about 55% mortality among our coastal oak, quercus agrifolia, populations. If this or a worse scenario were to play out in Garber Park, the entire character of the park would be altered and much of the heritage quality would be compromised or eliminated. In addition, like the ravaged tan oak forests of Marin County, Garber would present an incredible fire hazard due to the parched remains of toppled oak trees.

The “SOD Blitz” samples test for the presence of the pathogen in Bay Laurels, but the infection of the oaks and the appearance of symptoms among them, follows the infection of Bay Laurels by about two to three years. In Garber Park it appears that we have an opportunity right now to assess the situation, to locate the infected Bay Laurels and consider whatever mitigation alternatives seem appropriate. We have a chance to slow the progress of the disease, perhaps to achieve a stalemate. But both strategy and action are required right now—the window for mitigation is closing, faster perhaps because we are looking for a third consecutive warm and wet year in Claremont Canyon and in the Park. Dr. Garbelotto has seen two previous three-year sequences of warm rain which have produced great and rapid expansions of this water-borne pathogen.

The Garber Park Stewards will be seeking the opinion, experience, and advice of those professionals who have followed and studied the spread of the SOD pathogen, and we will look to the City of Oakland as well as the County of Alameda for policies and practices evolving to address the widespread presence of the pathogen in all the watershed lands of the East Bay ridge. The infection is regional, but remedies and mitigations, if they exist, may well be local and specific. We hope the North Hills neighborhood will join us in our efforts to seek the best next-steps for Garber Park and also, for our own back yards.

For those who wish to hear, first hand, Dr. Garbelottos’s presentation of the results for our area, there is one further community meeting scheduled this fall: Wednesday, November 16, 2011 at 7 PM, at the Dimond Library, 3565 Fruitvale Ave, Oakland, hosted by Friends of Sausal Creek.

Dr. Garbelotto’s Treatment and Mitigation workshops are now scheduled in our area for the following Wednesdays: October 26, November 9, and November 16. Attendance is free but a reservation is required which may be made on line at http://www.matteolab.org. All of the treatment workshops will be conducted at the Portico of Tolman Hall on the UC campus (a map is available on the website). These are outdoor meetings, held between 1 and 3 pm, rain or shine.

For the results, the meeting schedules and previous publications on SOD, please consult http://nature.berkeley.edu/garbelotto/english/index.php. Results for the SOD Blitz 2011 can be viewed at:
http://nature.berkeley.edu/garbelotto/english/sodblitzresults2011.php. In addition, the regional results were set forth in a recent SF Chronicle article: http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2011/10/01/MNG71L9OAK.DTL

At this point, based on the “SOD Blitz” samples taken this past Spring in Garber Park and more broadly in the East Bay North Hills/U C area, the conclusion is PERVASIVE INFECTION. We’ve got it.

CREEK TO BAY DAY 2011 IN GARBER: FALL CHORES DONE

 This year's Creek to Bay Day event in Garber Park was very different from last year's.  One year ago we were clearing large areas and steep hillsides of decades of garbage and debris, but this year we were able to tend and advance the goal of restoration of the park's riparian woodland ecosystem.   We picked out three work areas and our great volunteers accomplished all our goals.  We were able to clear the entrance hillside of invasive Erharta grass so that the native seeds from our restoration beds would have a better chance of rooting when the rains come and the growing season begins.  Along those lines, the stalwart blackberry cadre took out a large stand of Poison Hemlock that had sprung up on the banks of Harwood Creek in the open areas that had been previously cleared.

        
 Lech Naumovich's CITIZEN SCIENCE WORKSHOP was able to establish and carry out the transect of Garber Park following Harwood Creek from top to bottom.  Lech, Bob, and Janet established the beginning point and measured, marked, and collected data for about 60 feet of the transect, leaving a good amount of work still to be done at future workshops.  On the way to photograph them, I was astonished to run into a substantial patch of Aster radulinus, a shy and very infrequent native that we have not seen in Garber to this point.


 Creek to Bay Day which is expertly organized by the City of Oakland is a great opportunity to get work done and to assess developments in the Park.  The Stewards are grateful for this program and look forward to next year's event.

CREEK TO BAY DAY IN GARBER PARK

SATURDAY, SEPTEMBER 17, 9AM-NOON.  Wildland Volunteers, please join us in Garber Park for CREEK TO BAY DAY.  The Garber Park Stewards are offering three structured restoration activities each designed to advance the native riparian character of our oak woodland.  All levels of interest and capacity are welcome and invited.

1) ADVANCING THE EVERGREEN LANE ENTRANCE RESTORATION BEDS

At the Evergreen Entrance, there are five restoration beds now nearly one year old.  Extensive maintenance, native identification, documentary photography, boundary demarcation, and native seed collection will assist in the planned expansion of this very successful project.  The native restoration of the entire hillside is our goal.

2) FRENCH BROOM, CAPE IVY, AND POISON HEMLOCK REMOVAL FROM MIDDLE COURSE CREEK BANKS

Halfway around the Loop Trail, the removal of Himalayan blackberry which choked the creek has left a sunny expanse that has invited opportunistic weeds including French Broom, Cape Ivy, and a large stand of Poison Hemlock.  One good volunteer session will clear the area of these invaders making way for the slower resurgence of the native creekside flora.

3)MAPPING HARWOOD CREEK THE DIRTY WAY

Lech Naumovich of Golden Hour Restoration Institute will conduct a special CITIZEN SCIENCE workshop.  This will accomplish the first ever super transect of Garber Park, from the top of the park down to Claremont Avenue, following Harwood Creek.  Lech will utilize a scientific method (point intercept) to record vegetation and creek features every meter as we travel from top to bottom.  Data will be used to create a vegetation map of the current conditions of Harwood Creek.  Be ready for some hardcore science as well as some mud, as we travel from top to bottom.  Since this activity is optimal with only (12) twelve participants, please RSVP to Lech at lech@goldenhour.org  by September 15 if you are interested in this workshop.

MEET at the Evergreen Ln. Entrance at 9AM, sign in, enjoy some coffee and snacks, and then be ready for an enjoyable morning of restoration work.

MIMULUS AURANTIACUS--STICKY MONKEY FLOWER GARBER'S AUGUST 2011 FLOWER

Although the pervasive aridity of August in Garber Park dulls the expectation of encountering flowers, in fact from the vantage of the Loop Trail the cheerful multiplicity of golden blooms put forward by our native mimulus catches the eye of most visitors.  Properly a shrub, mimulus aurantiacus, known popularly as Bush or Sticky Monkey Flower, occurs in several spots in Garber and also occurs directly across the road on the much more exposed and dry north slope of Claremont Canyon in chaparral conditions.
Our riparian woodland Monkey Flower constituents do not exhibit the parched aspect of their canyonside neighbors, preferring to appear waxy and brightly colorful though they are not rooted in especially moist soil.  Calflora shows the distribution of aurantiacus in California as north to south, border to border, one or two counties deep along the Pacific coastline and also in the western Sierra foothills, mostly in the context of "northern oak woodland".  A number of variants of mimulus aurantiacus have been observed and reported in other limited areas in California, but none of these are apparently wide spread.
We do not have so many examples in Garber Park that they might be called common, but there are a small number of healthy, good sized shrubs--enough to feel certain that Sticky Monkey Flower is comfortable among the many floral varieties that grow beside it.  It is always a delight to find, wherever one runs across it.

SEED COLLECTION AND DISPERSAL WORKSHOP 2 - THE ROLE OF GRASSES

On Saturday, August 20, Lech Naumovich, Golden Hour Restoration Institute led another fun, informative, and hands-on seed collection workshop in Garber Park. Our first seed collection event in June focussed on the "early" bloomers in Garber. The goal of this second seed collection workshop was to collect and disperse the later maturing seeds - especially the grasses. The workshop began with a discussion of the basics of native seed collection, followed by a short walk to the Garber Park Stewards first restoration site at the Evergreen Lane Entrance.

Not yet in bloom this pretty white flower will be a fall
highlight.

The five beds at Restoration Site 1were all planted with a variety of native plants and grasses that grow naturally in other parts of Garber Park. We were excited about our first "harvest" - we planted this past February.We opened mature seed pods, collected them in paper envelopes, and spread them in a newly cleared area at the restoration site. We then walked along the Lower Loop Trail where signs of fall were everywhere, most evident by the crunching noise of fallen leaves beneath our feet as well as the few dried stalks of cow parsnip still standing. But we also found many plants still blooming - the sticky monkey flower (mimulus aurantiacus), bee plant (scrophularia californica), fairy bells (Prosartes Hookeri), and ocean spray or cream bush (Holodiscus discolor) - which means we'll have many more opportunities for seed collection throughout the fall.

A few of the highlights we learned on seed collecting:

• Never collect more than 10% of the seed of an established population. For newer sites, such as our Restoration Site 1 only collect 2-5%. We want to keep the site intact and healthy for future generations.
• Ascertain maturity of a seed by picking and checking before making a large collection.
• Always look for bugs. You don't want those seeds.
• Grasses - seeds on the head ripen progressively so at any one time both immature and mature seeds are present.
• Seeds need to be dry. Don't put in the fridge right away, let them dry out first. Store seeds in a paper bag or envelope.
• Label the envelope with the species common name (or Latin if you know it!), collection place (easy with phone with GPS app), and date.
• Seed viability: Annuals for the most part have low viability. Grasses viable for 3-5 years. Want to get the first seeds of the season for the best viability.
• Highest germination occurs the first year. Perrenials - 1st year seeds are the best seeds.
• Berries - we're competing with wildlife! We found this on thimbleberries which had no berries remaining.

•

  California Buckeyes are mostly mature trees in Garber. We are restoring the conditions to bring back the buckeye. Because the deer think the tender young leaves are so delicious we have placed cages around several young plants to give them a chance to mature. At Bob's Place there is an Oregon Ash that we need to cage as well.

And a couple of general restoration techniques:

• For many of the invasives, especially thistles, "mulch cut" (make several cuts at the same time starting at the top, cutting into small pieces working towards the ground) - the plant won't grow back.
• Direct rainfall on a hillside starts erosion. A good way to reduce sheet flow down the hill is to create "natural water bars." On our restoration site 1 we used logs to create irregularly shaped planting beds. What about Jute netting or cardboard? Except on large planting areas Lech prefers creating the Natural Water Bars.
