I had a phone date today with
Sylvia of the City of San Diego,
a Code Compliance Officer for
the Fire Prevention Bureau,
Fire -Rescue Department.
It was a friendly conversation.
We need to work together.
I want to activate the neighbors
surrounding what I am calling the Arosa Street Canyon.
It calls to be a Friends of the Arosa Street Canyonland Group.

The 32nd Street Canyon friends
asks the City not to cut, but that was on public
rather than private land.
The land in our canyon butts up against our property.
We use it for organic growing of food and trees.
There is also an organic farm in the Canyon.
There are also endangered species in our canyon
and a home to fox, possum, raccoon, squirrels,
coyotes. There are also rare and special bird life
that come to visit here in various seasons.
There are also various kinds of wild herbs growing
in the canyon including black sage, and other varieties.
This is an important nature preserve
and needs to be carefully managed for future generations.
My own vision is that the Enchanted Garden where I live
will be a park leaving a legacy in future years, and a finishing
school where nearby students from San Diego State University
can get a sense of how things grow naturally.
I will further be launching this awareness of our property
when I visit with Organic Stakeholders during my upcoming
trip to Washington D.C. and Baltimore.
I have to say most of the poor economic decisions we are making
now can be traced to losing our beat with nature. An important
way home is through relearning to grow a bit of our own food.
Organic food and Round Up Ready do not mix chemically, philosophically,
or ethically.
We have a stand of Arundo Donax that is considered a fire hazard
here. I agree this needs to be managed.
I would like to be one of the first successful properties that
demonstrates that this invasive grass, that does provide
privacy can be managed without dangerous herbicides.
There is an increasing awareness that using Glysophate
and round up ready is dangerous to human health.
Organic growing practices are a solution.
Arundo are grasses.
Grasses treated with Round Up Ready
Can continue to evolve into superweeds.
SUPERWEEDS AND ROUND UP READY
Here is an article about the 2011,
the Summer of Superweeds.
The City of San DIego is already coming
to the table about Community Gardens.
I see the need to better manage the Arosa Street Canyon
as an opprtunity for community to come together
and engage in some important Dialogue on Science,
Ethics, and Food.
We cannot continue to go the Round Up Ready route,
not can we avoid the fact that Natural preserves that honor
labor intensive methods of community coming together
may be just the opportunity here.

DANGERS OF ROUND UP READY FOR
IN OUR FOODS
Don Huber spent 35 years as a plant pathologist at Purdue University and knows a lot about what causes green plants to turn yellow and die prematurely. He asked the seed dealer why the SDS was so severe in the one area of the field and not the other. “Did you plant something there last year that wasn’t planted in the rest of the field?” he asked. Sure enough, precisely where the severe SDS was, the dealer had grown alfalfa, which he later killed off at the end of the season by spraying a glyphosate-based herbicide (such as Roundup). The healthy part of the field, on the other hand, had been planted to sweet corn and hadn’t received glyphosate.
This was yet another confirmation that Roundup was triggering SDS. In many fields, the evidence is even more obvious. The disease was most severe at the ends of rows where the herbicide applicator looped back to make another pass (see photo). That’s where extra Roundup was applied.
Don’s a scientist; it takes more than a few photos for him to draw conclusions. But Don’s got more—lots more. For over 20 years, Don studied Roundup’s active ingredient glyphosate. He’s one of the world’s experts. And he can rattle off study after study that eliminate any doubt that glyphosate is contributing not only to the huge increase in SDS, but to the outbreak of numerous other diseases. (See selected reading list.)

THE ARUNDO DONAX GRASS
AN INVASIVE SPECIES NEEDS TO BE REMOVED
SYLVIA TOLD ME
Some call it cane.
Some imagine it is bamboo.
It is a grass, a grass that is invasive
that has the lovely quality of here
of creating privacy.
Sylvia points out it is a an invasive plant.
It was here when I arrived.
I do not know when it was planted.
HERE IS SOME INFORMATION ABOUT IT
My first job now is to get beyond the shock
that we need to remove it.
It helps to blog about it.
HERE IS SOME RESEARCH
http://en.wikipedia.org/wiki/Arundo_donax
THIS POINTS OUT HOW DIFFICULT TO REMOVE IT
Full control requires decades of follow-up treatment of the regrowth by additional manual cutting and treatment with herbicides. Removal of the root systems is impractical. Furthermore, arundo removal must be initiated at the top of each watershed because the persistent plant has the ability to break off and transplant itself downstream. However, after the long battle against arundo is waged, native willows, sycamores, and cottonwoods can be replanted or regenerate
An estimated 8,000 to 10,000 acres of arundo inhabit the Santa Ana River watershed. To date, about 1,500 acres have been removed. Initial removal of one acre of arundo costs $5,000 to $9,500, but removing the plant by cutting it off above ground only stimulates additional growth from its massive root system.

Compounding problems in removing arundo is the fact that some commercial nurseries sell it for use as a privacy screen
because of its dense growth. It is hoped that soon the California Department of Food and Agriculture will ban the sale of arundo in the state.

How to do it?
PILOT PROJECT IN SANTA BARBARA COUNTY
TO USE LESS HERBICIDES AND PESTICIDES
South County Herbicide Limitations
As a pilot effort for the past several years, County Parks has severely restricted the use of herbicides and pesticides in the South County region (south of the Santa Ynez Mountains from Rincon Point to Gaviota). Virtually all landscape maintenance in the 680 acres comprising the South County area is done without use of herbicides or pesticides. This fairly comprehensive proscription is occasionally reviewed on a case-by-case basis when a particular project requires very limited use of an herbicide (for example, as part of a native plant restoration project to prevent reemergence of a non-native invasive plant).
In the South County park area
since July 2007 this exception has been used only once,
for a project to remove invasive Arundo donax
at Lookout Park in Summerland.
Eliminating regular use of broad spectrum herbicides such as glyphosate-based Roundup does increase the amount of time and cost of weed abatement. Our experience is that the cost for mechanical weed abatement (man-hours and weed abatement equipment) is up to ten times more costly on a persquare-foot basis than for previous controlled use of a glyphosate. In developed open spaces we typically use mulch around some lawn perimeters where there are shrubs or trees, in sidewalk medians, playgrounds and small sloped area and pathways. To maintain these areas staff must monitor closely and consistently follow up with hand weeding, steaming, or re-mulching. A controlled flame with a burn bottle is used to eliminate weeds in parking lots, sidewalk cracks, and in decomposed granite areas.

REMOVAL OF ARUNDO DONAX
Chemical and mechanical methods
The first combination of chemical and mechanical methods is called the cut-stump- herbicide application method (see figure 1.6D). This technique requires the cutting of the Arundo stalks and applying an undiluted glyphosate or other approved herbicide directly to the stump. “The cutting process has two steps. The first step is to cut the canes 1 to 2 feet from the base and remove the cuttings. Then, re-cut the stalks down to 2 to 3 inches and then apply the herbicide to the stumps within 2 to 3 minutes” (Cornwall, Dale, and Newhonser, 1999). This method can be applied throughout the growing season and is most effective in the early summer or early fall before the plant enters dormancy. It is appropriate in most proposed sites and best for mixed vegetation that is near water. The side effects include the risk of spillage of the herbicide and a slight risk of soil damage of disturbance and erosion when removing the cane. The cost of this method is moderate because there is very little herbicide wasted with precise application. Non-target losses are also avoided with this method and the follow up treatments is minimal. The success rate ranges from 50% to 95% in the first year and can take up to 3 to 5 years to fully eradicate Arundo.
A second method of the combination of chemical and mechanical methods is the cut-

14
stalk-re-sprout-spray method. First, the Arundo stalks are cut and then the biomass is removed. Then, allow 3-6 weeks to pass so that the plant can grow one meter tall and then the foliar application of the herbicide should be sprayed on the new growth. This method is appropriate to use in situations where Arundo is mixed with desirable native vegetation. The advantage of this method is that there is less herbicide applied to treat the new growth but the disadvantage is by cutting the stalks it results in the plant returning to the growth phase. This means it is drawing nutrients from the root mass and there is less translocation of the herbicide to the roots and therefore less root kill. Another disadvantage of this method is that it requires many follow-up treatments, which means more manpower and herbicide application and desirable vegetation may be effected by the spraying technique. “The success rate of this method is 50% in the first year and 75% in the second and third year of growth. It may take up to 3 to 5 years for full eradication of Arundo” (Cornwall, Dale, Newhonser, 1999).
An alternative approach that has not yet been tested on Arundo donax in the U.S. but has been effective in controlling Fallopia japonica, a similar species, has to do with depleting resources in the root mass. It involves repeated cutting of the shoots to deplete below ground carbohydrate storage in the rhizomes (Boose and Holt 1998). Another alternative approach that has not yet been tested in the U.S. is biological control using a variety of insects and pathogens. Tom Dudley from the University of California Berkeley and others traveled to Nepal and India in 2001 in search of these potential candidates. They discovered in Nepal a variety of candidates that have a negative affect on Arundo. They include a stem boring moth larva, a stem boring beetle larva, a moth that mines the leaves, leaf-hoppers, and other Hemiptera that feed on new tissue. In South Africa, they found that there was evidence of insects boring in the secondary shoots of Arundo. The introduction of non-native species as a biological control for eradicating Arundo poses a potential threat for the introduction of yet another invasive non-native species. From this discovery it appears that biological control of Arundo research will be conducted in the very near future. These future studies should take into consideration the potential risks of introducing a non-native species to eradicate another invasive non-native species.
Removal and disposal of Arundo donax debris Lastly, the biomass removed after the treatments must be carefully dealt with to ensure
that there is little chance for new invasions. The fresh cut stems and canes can be still viable and capable of re-sprouting and re-rooting, which means extreme care must be taken when removing stems and cane after cutting. There are four different ways in which Arundo debris can be dealt with after the removal method is applied.
Firstly there is composting, which includes letting the debris sit and rot in place. Usually it will decompose slowly in a pile above the high water line and out of the way of high water flow. This method is ideal for remote areas. Chipping is another method but it can be more costly due
15
to the equipment and labor costs. Another method is dumping which is hauling the biomass away but this can be extremely expensive and many landfills are not willing to accept the biomass of Arundo.
Lastly, the most cost-effective method for removing the biomass is by fire as long as it does not threaten the native vegetation. There are restrictions when burning is considered that must be followed. A burn permit is required from the fire department during the fire season. The fire department requires the burn area to be confinable and far from the brush or overhanging trees. They also require the Arundo pile should dry for 60 days to meet the Air Quality Management District restrictions.
