Wild Turkey

P90224This is a relatively new development. The first few arrived here only two years ago. By last year, a few more arrived to make a significant herd that split into two smaller herds. Now these two smaller herds are quite significant. If they continue to proliferate as they have been, they will become more of a problem. They are already shredding flowers and colorful berries that are within their reach, and digging up flexible irrigation hoses.
They are not really wild turkeys, since they are not native here. They are actually feral turkeys that escaped into the wild and naturalized. They may have moved in from surrounding areas, or they may have escaped locally. Turkeys have been roaming parts of Scott’s Valley and my neighborhood in the Los Gatos Hills for a few years. Much larger herds roam other regions, particularly the Diablo Ranges east of the San Francisco Bay Area.
My former neighbor knew how to select the good ones. They all look the same to me. When they showed up on the road at my home, I could just chase them to the neighbor’s home, where he would take what we wanted. They were so stupid that he probably could have grabbed the good ones rather than shoot them. It is amazing that they could survive in the wild so stupidly.
I suppose that it was good that they survived to keep the meat fresh. However, I am now concerned about how these exotic and prolific birds might affect the ecosystem. Are they taking food from other wildlife? Are they dispersing seeds of the fruits they eat differently from other birds who eat them and fly away to other areas? Are they providing too much food for predators, and allowing them to proliferate more than they should naturally?P90224+

ICK!

P80915K.JPGJust about everything in this picture is icky! This species of pampas grass, Cortaderia jubata, is one of the most aggressive and noxious of the invasive exotic specie that have naturalized here. It seems to be incarcerated behind the weathered cyclone fence with barbed wire on top. The big water tank is is a harshly stark background. The tired old Douglas firs and ponderosa pines to the left and right seem to be unhappy here. The small coast live oak that is at least trying to make a more cheerful appearance is only oppressed by the surroundings. Only the clear blue sky above lacks the ick factor.

What is not visible in the picture is that there is no other flora in the area. Most of the area is covered with a thick layer of gravel to prevent vegetation from getting established close to the water tank. Weeds that manage to grow get cut down regularly. Only the pampas grass survives the ravages of the weed eater. It has been allowed to stay only because it has not yet been perceived to be a problem. It will probably be removed eventually as well. It would have been much easier to remove before it got so big. Now that it is blooming, it is likely to sow seed for more of the same.

Whomever gets the grim task of removing the pampas grass must contend with the nasty ‘razor grass’ foliage. The very sharp and very finely serrated edges of each leaf cause the worst sort of paper cuts! Even if handled very carefully, the long strap leaves have a way of getting everywhere. Someone tugging the base of the foliage with gloves and long sleeves can lose an ear to just one of the many long leaves that whip around so aimlessly.

However, someone who is unfamiliar with the serious nastiness of pampas grass might see this picture very differently. The firs, pines and oaks are not so bad. The water tank is a neutral background to the subject matter. The weathered cyclone fence with barbed wire on top, . . . well, let’s just say, . . . it’s ‘abstract’. Anyway, to someone who does not know better, the fluffy floral plumes of pampas grass that toss so many seed that have the potential to grow into an indefinite supply of the same nastiness are actually quite pretty.P89015K+.JPG

Scarlet Pimpernel

P80826It is pretty but pervasive. Actually, I do not really find scarlet pimpernel to be all that appealing, but this is how someone who reads my gardening column in the Santa Ynes Valley News describes it. Embarrassingly, she requested that I discuss scarlet pimpernel while it was more of a problem back on June 7, but I only recently read the message. By now, it is already dying back for autumn, and is completely deteriorated in dry and hot exposed areas. It will be back next spring, and will bloom with tiny peachy orange flowers so that it can throw tiny but ridiculously abundant seed by summer before anyone notices. Flowers can be other colors in other regions. The sprawling stems can spread more than a foot wide, and can get up to about ten inches high if sprawling over other weeds. The tiny and soft leaves are arranged in opposing pairs. Scarlet pimpernel may not seem like much of a threat now that it is deteriorating, but new seedlings will be profuse early next spring, and can compete with seedlings of more desirable plants.
Control of scarlet pimpernel is not easy. If application of herbicide is an option, it does not stick to the foliage of scarlet pimpernel very well, even with a wetting agent. Hoeing eliminated larger plants, but does not kill the seed that the larger plants have already tossed. Scarlet pimpernel starts throwing seed so early that it must be pulled as soon as it appears in very early spring. Like I said, it is not easy. The small plants are not even easy to see. The process must be repeated at least weekly for a while, just because some seedlings will emerge after the first batch is gone.
Fortunately, scarlet pimpernel is not very vigorous. If it comes up through mulch, only a few plants will survive, and they will be easy to pull. They do not compete with other more vigorous plants well either. Many simple ground covers will simply shade it out, although it can mingle with and ruin some of the finely textured ground covers like baby tears and thyme.
I am sorry that I do not have any more information about scarlet pimpernel than is commonly known. I am speaking primarily from experience, and my experience has not been as bad as with other more aggressive weeds. Scarlet pimpernel always seems to be around, but is not so much of a problem that I am too worried about annihilating it completely.P80826+

The Good Weed

P80616KOnce in a while, a stray seed of a plant that would normally be considered to be an invasive exotic species happens to grow in a spot where it happens to fit. Those of us who regularly pull up unwanted feral seedlings, are typically skeptical. We probably pull up many such seedlings merely because we do not trust them, or because we do not want them broadcasting their seeds elsewhere in the neighborhood. In our region, Acacia dealbata, blue gum eucalyptus, black locust, pampas grass, broom, poke berry and Himalayan blackberry get no consideration; and their seedlings should be removed as promptly as they are discovered. English ivy does not get much more consideration, but every once in a while, it happens to wander into a situation where it is allowed to stay.

Catalpa is one that we are not quite sure about. It is an exotic species that happens to disperse unwanted seed at times, but is not invasive enough to warrant prompt removal of all seedlings. Many seedlings appeared in the area several years ago, and most were removed because of where they were. However, if any other seedlings have appeared since then, they have been discreet enough to remain unnoticed. It was as if there was a very specific mating season. Catalpa had not been invasive prior to that, and has not been invasive since.

Two of the feral catalpa seedlings appeared on the edge of the parking lot at the Felton Presbyterian Church. One became disfigured and distressed, and finally died before being removed. The other just happened to be in the middle of a parkstrip, and in a location where a good sized shade tree had room to grow. Because no one could find a good reason for removal, it stayed. After only a few years, it is now a good sized and very well structured shade tree that blooms nicely this time of year. It may not last long, since catalpas are short lived, but for now, it is a nice component to the landscape. This weed gets a happy ending.

 

Six on Saturday: Blackwood Acacia

 

Blackwood acacia, Acacia melanoxylon, happens to be one of my least favorite trees, but it does happen to be rather interesting. Mature trees have no leaves. Really. I don’t mean that they defoliate through winter and refoliate in spring. Only juvenile growth has bipinnately compound leaves. As growth matures, leaves are smaller, and are outfitted with distinctively winged petioles. As growth progresses, the winged petioles, known as ‘phyllodes’, become more prominent, and lack vestigial leaves. Therefore, once mature trees outgrow their juvenile growth, no leaves remain.

I dislike blackwood acacia because it is an invasive exotic species, like Acacia dealbata, but not as invasive. Mature trees sucker profusely from roots to form groves of several straight and vertical trunks. Where they are not a problem, groves of mature trees are rather handsome, but do not last long before they start to deteriorate. Foliar liter has an herbicidal effect that inhibits weed growth, but also inhibits the growth of desirable plants. It also produces an objectionable aroma.

1. Juvenile leaves are bipinnately compound, like those of Acacia dealbata.P80310
2. Leaves become more diminutive with distinctively distended petioles as growth matures.P80310+
3. Adult foliage is comprised exclusively of phyllodes, without leaves. The phyllodes function and look just like simple leaves.P80310++
4. Blackwood acacia flowers are not much to look at. Even in full bloom, they are grungy yellowish white.P80310+++
5. At least the bark is handsome.P80310++++
6. The best blackwood acacia is a dead blackwood acacia.P80310+++++

More Misplaced ‘Environmentalism’

P80214Nature has been getting by just fine for a very long time before humans started to interfere. It has survived all sorts of catastrophes literally longer than anyone can remember. It was here when dinosaurs were exterminated by a meteorite or comet or vulcanism or whatever catastrophic yet natural event finished them off. In fact, Nature was here for all of the few mass extinction events of the very distant past, including the Permian – Triassic Extinction, which only about 4% of life on earth survived! We all know that β€œIt’s not nice to fool with Mother Nature.”, or serve her margarine that tastes like real butter; but we should also realize that it is rather presumptuous to think that we can be more efficient with correcting all environmental damage. Very often, it is best to let nature do what nature does best.

For example, forest fires are perfectly natural. They are more frequent now because of human activity; but they are less extensive, likewise because of human activity. Humans contain fires that would naturally burn much larger areas. Preventing vegetation from burning allows it to accumulate and become more combustible. If deprived of fire long enough, vegetation within ecosystems that rely on fire as part of their natural restorative cycle eventually deteriorates, or become so combustible that when it does burn, its seed gets incinerated.

Many box elders along the San Lorenzo River have been dying for the past many years. We have not identified the pathogen associated with the necrosis, but it is probably a naturally occurring pathogen that is an intricate component to the natural ecosystem, (although after last winter, an inordinate number of box elders succumbed at the same time). Regardless, trees succumbed and fell. A significant void developed within the collective forest canopy on the Eastern Bank, near the Graham Hill Road Bridge. ‘Environmentalists’ wanted to ‘help’.

These new trees in the picture were planted within the area vacated by a few deceased box elders. The closer of the two is a coast live oak. The other is a bay laurel. There are a few more beyond those in the picture. Native vegetation that developed ‘naturally’ but happened to be in the way was removed to facilitate this project. To prevent native deer from damaging the trees as deer would do ‘naturally’ the trees were imprisoned in small cylindrical cages. Because the trees did not grow there and disperse their roots ‘naturally’, they must be irrigated until they can survive on what they get ‘naturally’ from rain.

The irony of all this is that native vegetation that was growing ‘naturally’ was removed to install ‘unnatural’ nursery grown trees intended to restore a ‘natural’ ecosystem that was already doing what it does ‘naturally’. Although native, the coast live oak ‘naturally’ prefers to avoid riparian environments such as this. It ‘naturally’ prefers a more exposed and drier situation. Bay laurel trees live there ‘naturally’, which is why a few had already started to grow from seed. These seedlings would not have needed to be caged or watered, but were removed to plant the new trees. Yes, bay laurels that would have survived on their own were replaced by bay laurels that must be watered and protected. Willows and cottonwoods that were quite prolific in the area were likewise removed, although many more remain lower on the bank of the River.

In the background, in the upper right corner of the picture, the bright yellow flowers of an Acacia dealbata can be seen. It is a seriously invasive exotic species that displaces native vegetation. Although it is impossible to exterminate the species, this individual tree that has been dispersing profuse seed into the San Lorenzo River for many years, really should be removed. Even if nothing were to be installed to replace it, the removal would benefit the ecosystem. Nature would have no problem finding native trees that would like to occupy that spot.

Invasive Exotics – Acacia dealbata

P80211Every invasive exotic (non-native) species has a story of how it got here.

Blue gum and red gum were imported to produce the timber needed for railroad ties. Many annual specie were forage crops for grazing cattle. Some got here by stowing away as seed on or inside cattle or other animals. Supposedly, mustard seed was broadcast by those traveling on the El Camino Real so that other travelers could find the route later. Then there are all sorts of invasive exotics that were imported simply because people liked to grow them in their gardens.

It is difficult to imagine why anyone would import any of the weedy specie of broom (Genista specie) or the sloppy species of pampas grass (Cortaderia jubata). It might have made sense at the time, before more appealing specie were introduced, or before less invasive modern cultivars were developed. Black locust has always been, and continues to be a pretty tree, long after more colorful and less invasive cultivars were developed. They were brought to California by prospectors from the East at a time when no one knew or cared how invasive they would be.

Acacia dealbata was likewise imported simply because it is a pretty tree, before anyone knew how it could naturalize and displace native vegetation and wildlife. Now it grows very rampantly in utility easements where other vegetation has been eradicated. Not only does it interfere with the efficiency of utility cables, but it is also combustible if ignited by sparks from electrical cables. Yet, it is so colorful and pretty in the middle of winter that it is not easy to dislike. Unfortunately, environmentalism is not what it used to be, and some so called environmentalists want it to be protected simply because it is ‘alive’.P80211+

Oklahoma

P71119Standin’ on the corner in Winslow, Arizona, specifically on the corner of West Second Street and North Kinsley Avenue, there was this bronze statue of someone famous. I am still not certain who he was. A statue of Glenn Frey was added nearby later, and might have replaced this one, but I could not find much news about it. The new statue does not look anything like this statue, which was the only one there when we stopped to get our picture taken there five years ago on our way to Oklahoma.

We did not plan the trip very well. We did not plan it much at all. We were in a less than ideal situation at home, so loaded up a tired old Blazer and went on our way. I sort of planned on staying for a few days or maybe two weeks, and then returning alone to Felton, and then tending to some work near Hilo in Hawaii by early December. Steven and Gayle who are with me and the bronze guy in the picture were to stay in Oklahoma. Of course, even these meager plans did not go as planned. I stayed much later, and all three of us, Bill the terrier and Darla the kitty all returned to Felton on the last day of 2012.

What a trip! It was the farthest I had ever gone from the West Coast, and the longest time I had ever been out of California. It was my first time in another time zone, and then another! I actually ‘lived’, albeit temporarily, in Oklahoma; and I got to drive through Arizona, New Mexico and a small part of Texas to get there!

I had always wanted to go to Oklahoma because I had heard so much about it growing up. My maternal grandmother was an Okie, so much of what I learned about horticulture was from that background. To me, it was one of those magical places where great grandparents lived and grew tons of fruits and vegetables in the rich red soil on their farm. It was where the wind comes sweepin’ down the plain, and the fragrant wheat sure smells sweet . . . okay, so maybe not that part.

Oklahoma certainly did not disappoint. It was exactly as I knew it would be, but was completely fascinating anyway. Pecan, black walnut and various hickory trees grew wild, as well as American persimmon, Eastern red cedar, redbud, honeylocust and blackjack oak. Vacant parcels were overrun with native red mulberry, campsis, honeysuckle, Arkansas yucca and sumac. I collected seed from more specie than I can remember.

The funny thing about all this is that the Okies did not understand my interest in all their flora. Much of it was the sort of stuff that they cut down and burn. The Eastern red cedar, honeylocust, red mulberry, campsis and sumac were quite unpopular for their habit of growing into rangeland. Even less invasive plants did not impress those who had always been around them. To them, redwood, big oaks, avocado, citrus and all the cool exotic specie that we grow in California are much more interesting. It was a matter of perspective.
