Question: Why don't Eco-Activists save things closer to home in their own backyards ? 2nd Question: Why do so many of them rarely volunteer for any restoration projects ?

This is just one of many island-like Hills which are located within the El Cajon city limits. Most of the native chaparral is long since gone, replaced by non-native invasive weeds from the European Mediterranean or Northern Africa regions. This particular one was stripped many years ago and planted with the common Red River Eucalyptus from Australia. You can see the living and dead remnants on the top and the numerous cut stumps of those which were harvested. Still, the native chaparral plant community never did really come back, but there are some surprising hold overs.

On this Hill east of Gillespie Air Field is a hold over of times past. This is a Prickly Pear Cactus which surprisingly has gotten much bigger since I first encountered it in 2002. Still, you can see the overwhelming smothering of the non-native invasive weeds. However further down below near the Mobile Home Park, there is a rather large healthy colony near some large granite boulders and smooth flat granite bedrock where Metate Grinding Holes are located. No doubt the natives may have plant these some centuries back when their village was present

California Sagebrush (Artemisia californica) being overwhelmed and smothered by the heavy weedy intrusion of the non-native grasses like this cheat grass. This particular plant is the ONLY specimen on this entire hill. I know because I have thoroughly searched this entire hill for others. It is a main featured plant in saving and setting aside habitat for the California Gnatcatcher, such as the conservation area on Rattlesnake Mountain to the north of this location which demands that open space be set aside during the construction of the Sky Ranch Housing Development. We always wondered if one day some developer would come along and turn those mountains into another Mount Helix rich folks paradise to the south, but the mandated open space totally prevented that from happening.

Pacific poison oak (syn. Rhus diversiloba)
Finding this plant for the first time back in 2002 was a wonderful surprise and an unexpected shock at the same time. But interesting none the less because it further intrigued me as to what the orignal historic vegetation content of this hill was really like a century ago. Such a plantas this one I've only associated with areas of high moisture content, usually on on the north side of a mountain. The Rattlesnake Mountain chain to the north of this Starlight Hill location and would be like comparing a giant granite boulder to a small cobblestone. And yet, from all my decades of hiking up there on Rattlesnake Mountain, I never once stumbled across this plant species high up there.

This is the granite bedrock site of the native American Metate grinding holes. Notice the Prickly Pear Cactus which no doubt was part of the native's pantry and out of this picture frame to the left are some abundant examples of Mexican Elderberry, also a common plant near these village food preparation sites. The weedy invasive plants have a tougher go of it here, although they are still present.
|Mexican Elderberry (Sambucus mexicana)|
Just above the historic Native village site. Actually this small chaparral tree is very common in and around the rocks here on this hill. I find it ncredible how Europe is so crazy about their Native Elderberry Trees and local Californians pay them no mind nor give them a second thought as a cultivated found source like the Natives did. Not even the majority of so-called Native Plant enthusiasts.

A healthy chaparral plant community is a mycorrhizal one. On the other hand, the weedy type annual plants generally come from a flood plain with it's bacterial system where most of the nutrients wash down from the higher locations and collect and settle on the valley floors. In the old days, weeds never really got a foothold on mountainous areas or foothills, but times have changed as these areas have become richer in nutrient content, no doubt as a result of various pollution components by mankind which have gradually accumulated over the decades to allow for this unnatural succession of invasive non-native annual plant community to take over. Not to mention the complete disappearance of the healthy mycorrhizal community which outcompetes weedy ruderals for nutrients that keeps the weeds in check. This is where I took it upon myself while working there to experiment with a portion of that Starlight Hill that I have revealed to you in any of the photos. First thing that has to be dealt with on such a location is what I consider a radical extreme measure of dealing with any heavy weedy system in a swift kick blow to the weedy plants themselves. First step would be to use a weed eater or Fishing line power trimmer to cut down as far to the ground as possible any and all weeds. dead or alive. Next, while I don't like chemicals, in some extreme cases where used properly and not over done, products like Roundup can be used after the next rainy season growth appears. After this initial extreme KILL, heavily mulch these areas to suppress the newer weeds from appearing on the area to be re-established with chaparral or any other native plants from any area of the globe being restored. In the old days, most southern facing slopes had a sterile decomposed granite soil base spaced between the individual plants with the plant's own dander or mulch underneath it's own vegetative drip line. This is not the case now. In fact you cannot allow any bare spaces between plants for a few decades, given the changes which have taken place on our once pristine natural world. Allow these spaces and weeds will fill in these spaces. So keep these areas between plants mulched until they grow large enough to merge with each other. What I did on this hill project was plant both native Chaparral and native tree species, with the exception of a few non-native Mediterranean trees which can take drier conditions. Also remember, this hill site was to never have an irrigation system, so proper healthy natural establishment done the right way in the beginning was a must. The native chaparral plants I used were Lemonade Berry, Californian Holly (Toyon), Cleveland Sage, etc. You also need to correct the soil's microbiology back to a mycorrhizal one. Decades of neglect ensure almost no beneficial mycorrhizal fungi existed to maintain healthy plantings. It was imperative that a good species blend of mycorrhizal mix be added at the very moment of planting for a good healthy start and to change the underground soil structure and chemical makeup to something which would allow the plants to succeed. Native trees, believe it or not were Tecate Cypress and Coastal Live Oak, both of which thrived immediately. Non native trees were mostly volunteers of Aleppo & Canary Pine which were already around the properties below in the housing that was maintained by the company I worked for. What can I say is this, they were free and after all, it was only an experiment anyway. Even failure were to happen, this was a learning process. The first couple years the plants were babied with once a week watering the first several months down to once a month the second year. After that no more water. Such a watering strategy replicates what I learned here:
Okay, so below is a photo of basically what the once weedy area looks like today below here.

This is looking up the Landscape and Maintenance Service road for which plants were established on both sides of the road to provide privacy screening for the work of chipping and gravel and soil dumping which was necessary for the normal Park maintenance. Often times such areas are unsightly branches and trimmings piles and it detracts from the tidy cleanness of the Park Community. At the top where the road turns left, you'll notice the Tecate Cypress which actually provide a good green screening, Aleppo Pine is easy to identify and many of the small trees are actually Toyon and Lemonade Berry. Cleveland Sage is to the right.

This is looking back down the maintenance road. Notice the Silver Agave on the right. I collected that back in the 1990s from the Huachuca Mountains above Sierra Vista Arizona and brought it down we me when I left Anza CA. This Agave was actually growing on the forest floor up there under trees when I first discovered it. It originally was the size of my fist when I collected it. It was one of the pups around a bigger one.
|Cleveland Sage (Salvia clevelandii)|
This is on the south side of the maintenance road
|Aleppo Pine (Pinus halapensis)|
This is on the north side of the maintenance road opposite from the previous picture of the Cleveland Sage. Only weeds appear to be some Sow Thistle, but not much more. Continued use of mulch keeps them in check. These Aleppo Pine Trees here are 8 years old. There is absolutely no irrigation. My previous experiments in Anza California in dealing with the interconnections of a strong mycorrhizal grid network underground between a large group of pine trees are clearly present here as you can see these trees are exceptionally healthy with little or no irregation. This underground interconnected network between all the tree root systems can shunt water from lower reaches where some irrigation from the Park may be transported uphill to the trees at the higher elevations above. The front Office and pool are of the Park has some extremely large Canary Island Pines for which somehow became colonized with Pisolithus tinctorius truffles. Every Spring the truffles appears and I'd collect them. Most of the Pisolithus tinctorius inoculent used on this hill came from those truffles I collected. Now the only water is the little rain from winter's rainy season which has been mainly drought.
|Tecate Cypress ( Cupressus forbesii )|
These trees are actually larger than they appear here in the photo. I had to stand back quite a ways to include all of them. The lower tall slender one is almost 20 foot in height as it is much much lower at the bottom of the bank. All of them show no signs of slowing down to a comfortable growth. None, with the exception of the lower one receives any watering. The lowest one may have roots near some irrigated plants nearby.

Same Tecate Cypress, but now viewed from below the bank. All of the Tecate Cypress were also colonized with mycorrhizae. The soil is decomposed granite with some adobe red clay and very little organic material. Only organics are the mulches place around the rooted areas.
|Lemonade Berry (Rhus integrifolia)|
This is a large chaparral shrub and was given to me by the Company's owner to plant where I wished. This specimen came from Scripps Ranch area. I really was unsure if it would take as it had been in a one gallon pot for a long while after being transplanted from the wild. It looked stunted and could easily been written off, but fortunately, a good mycorrhizal mix is mostly all that was needed. To the right and on the back of the bush is wild cucumber vine growing up into the branches. How fortunate for the wild cucumber to fiend an old friend where most others are lacking.
|Coast Live Oak (Quercus agrifolia)|
Of all things that would disappoint me, is the sorry condition of the Coastal Live Oak as upsetting, but it's still alive. When I last visited here in July of 2011, the vegetation was healthy, thick and dense. Now the leaves are half green and half brown, almost as if poisoned with Roundup. Not sure how sensitive it's roots are, the new maintenance person may have sprayed to heavily dose of roundup around it to maintain the rid the area of weeds around it. Still it has been a success otherwise as I heavily inoculated it with various Ectomycorrhizae , in particular Pisolithus tinctorius. There is a volunteer Texas Umbrella or China Berry Tree growing to the right of the tree and it has wild Cucumber Vine growing up into it. I'll have to work on this area with permission of course.

Looking up at at the once weed infested hill from across the street below. I actually have a photo back in Sweden of this hill before anything was done, but I'll have to scan it at a later date and post it. The transformation is remarkable and possible for any location. I have actually got some conventional camera photos of this area before much was done, but I'll have to scan them and upload here later.

Looking down from the hill at the restoration project below. This is looking directly south towards Mount Helix in the southern end of El Cajon Valley.

Still Interested in Environmental Activism ???Then stop being distracted by the plethora of environmental non-profits who promise if you donate to them, join in monkey wrenching protests or trust their "Occupy" worldview of overthrowing an ideology they hate which will make the world a better place and challenge yourself to restoring a landscape they have written off as unsalvageable decades ago. Nature has always had the tools for turning things around again. Take some outdoor time away from time wasting Facebook sites and find out just what those tools are. Start with your own backyard or local habitat beautification project. It's local and not far to go time-wise and expense-wise as far as fuel is concerned. Areas of local restoration could include the entire restoration of the San Diego River riparian corridor from Mission Trails Regional Park all the way to El Monte Valley in Lakeside California. Or anywhere else on the planet where the misuse and abuse of Science by profit obsessed corporate entities has caused environmental ruin.
