This week in IPM -- Monday and Tuesday
Monday and Tuesday presented various opportunities for gruesome death, and those days are always interesting. We finally got to tackle some Russian olive trees, a weed for which I have an almost unusual level of personal distaste (and so do the chainsaw wielding members of the forest crew, who actually had to wrestle the beasts to the ground.) Opportunity for gruesome death number one was the multiple chainsaws. Number two was the chipper, a lovely machine with a diagram on the side of a stick man getting his hand caught in the cutting wheel and being pulled in to his death. The nature of this work necessitated constantly wearing a helmet and ear plugs. I like ear plugs because they keep me from going deaf, but I find that they become uncomfortable after 30 minutes, and painful after an hour. We were working in a large field that looked like a normal grassland, but it was actually irrigated (for the benefit of cattle, I suppose) so there were a lot of mushy spots, and we spent most of Monday morning in several inches of water that instantly soaked my feet and kept them soggy for the rest of the day.
Russian olives are hard to kill. They grow in a highly branched, bushy pattern that never presents a single, easy cut (unlike, say, most pine trees) and their hard wood stubbornly resists the bite of the chainsaw, much to the chagrin of the FEMP crew, who are all pretty awesome and hardcore guys to spend all day working in the sun with a tool that is heavy, hot, loud, sometimes breaks down, and works at a painfully slow rate against these damnable tree-weeds. I don't think I would have held up so well. Our job was comparatively easy, hauling trees and loading the chipper, and applying chemical to the stumps as soon as the trees were cut. The herbicide we used is called Garlon 4, which we usually use in dilution, but in this case it was 100 percent, the better, hopefully, to keep the Russian olives from resprouting, which they are very good at doing. We have to wear long pants and long sleeves and big rubber gloves when using chemicals, which intensifies the July heat. Also, Russian olive trees have thorns, but another tree we were also cutting, honey locust, is covered, trunk and limbs, in profusions of four inch long thorns that branch like antlers to many sharp, sharp points. You can bet between the heat, unwieldy power tools, and wooden spikes stinging through leather work gloves as easily as our own skin that there was a lot of cursing Monday and Tuesday. I did a lot of chemical, so I came out relatively unscathed -- minus an ugly scratch from a barbed wire fence -- but most of my coworkers look like they've been mauled.
Was it worth it? Well, I find that jobs requiring vigilance for safety make the day go faster, and we got to do something different, and most of all we got to kill Russian olives. On Tuesday afternoon we hauled out two tons of wood chips in our trailer, along with two other similarly sized and similarly filled trailers. Times two days, that's about 12 tons of weeds removed from the landscape, and the cool thing about killing big weeds is that you can really see the change you're making in the landscape -- in this case, opening it up and restoring it to plains grassland.
We also took down a few cottonwood trees, two of them twenty feet tall, healthy and beautiful. Why? We've decided this area is supposed to be a grassland, which means no trees, even if they are natives. I disagree. Cottonwoods mainly grow along riparian areas, yes, but they certainly can grow out on the plains away from obvious sources of water. Cottonwoods are beautiful natives. They're the good guys. Anyway, they were growing along a stream, albeit a manmade one. If we really wanted it to be a natural grassland, we'd eliminate the irrigation and the cows and let nature take its course with the cottonwoods while still working to remove the Russian olives and locust trees. Of course I think we did a lot more good than harm -- about twenty four thousand pounds of good, actually -- but I wish we'd have left the cottonwoods.
