Alabama Wages War Against the Perfect Weed

pickens writes "Dan Berry writes in the NY Times that the State of Alabama is spending millions of dollars in federal stimulus money to combat Cogongrass, a.k.a. the perfect weed, the killer weed, and the weed from another continent. A weed that 'evokes those old science-fiction movies in which clueless citizens ignore reports of an alien invasion.' Cogongrass (Imperata cylindrica) is considered one of the 10 worst weeds in the world. 'It can take over fields and forests, ruining crops, destroying native plants, upsetting the ecosystem,' writes Berry. 'It is very difficult to kill. It burns extremely hot. And its serrated leaves and grainy composition mean that animals with even the most indiscriminate palates — goats, for example — say no thanks.' Alabama's overall strategy is to draw a line across the state at Highway 80 and eradicate everything north of it; then, in phases, to try to control it to the south. But the weed is so resilient that you can't kill it with one application of herbicide, you have to return several months later and do it again. 'People think this is just a grass,' says forester Stephen Pecot. 'They don't understand that cogongrass can replace an entire ecosystem.' Left unchecked, Pecot says 'it could spread all the way to Michigan.'"

      My goats will clean up kudzu like it's candy. Not only will they strip the leaves, you'll see them standing on their hind legs trying to drag the vines down out of the trees. They eat leaves, vines, stems, roots and all. Reminds of a casino buffet on seafood night. And because they have a 4 chambered stomach, the digestion process pretty much kills the seeds. I've never seen them spread it anyway. As a bonus, goats can handle the terrain kudzu seems to thrive in.

      If goats don't eat cogongrass, then that is some bad stuff. They can strip the leaves off blackberry bushes while avoiding the stickers, all they leave behind are stands of dead stalks. If it's that bad...that's a real problem.

      The United States is now home to some of the most unruly plants in the world, like Kudzu vine, which has caused farmers to abandon crops at first sight of the vines at field's edge. It can be seen sneaking across highways on the lightning wires over power lines, and creating strange sculptures of the barns, tractors, and forests it covers throughout the southeast. Florida has two of these plants, the Kajeput, and the Australian Pine (Aussies call it American Pine..Apparently, nobody wants it) Both of these trees were introduced by the US Army Corps of Engineers to perform some function ancillary to one or another of their endeavors, but now reviled as environmentally obnoxious in their ability to grow in any condition from standing water to alkali flat. Kajeput has the additional benefit of burning hot to its top (oily sap and leaves) thereby killing off the native palms that used to survive naturally occurring fires. Remember what Newton said, "Nature abhors a vacuum". And stuff like these plants, and some of the other, more mobile creatures that have apparently taken heart and moved on from their original, pest-opposed environments, are now enjoying the benefits of life with no natural opposition, except people.

      Kudzu makes decent forage. Kudzu hay typically has a 15-18% crude protein content and over 60% total digestible nutrient value, slightly lower on longer vines. Unfortunately it's hard to bale and store.

      Since it stores a lot of starch in the roots, they can regenerate for a long time. My goats will eat anything that doesn't break off in the ground, including the seed pods. If they're still around, kudzu won't be able to get started again. They'll eat any vines that start. That includes kudzu, but also wild grape vines, poison ivy, and just about anything else that grows on a vine.

      If we could cultivate the market for goat meat in the US, those vast areas overgrown by kudzu would immediately turn into potential grazing land. Of course, in an environmentally sensitive area, the goats would be almost as hard on native plants as the kudzu. So there are trade offs both ways. But since goat is a red meat with roughly the same caloric value and 1/2 the fat of skinless chicken, 50% lower fat than beef, and 1/3 the calories of pork you'd think we'd be eating more goat.

      Under similar circumstances in Australia the CSIRO http://www.csiro.au/science/PestManagement.html , would investigate the weed species, find it's country of origin, find insects, bacteria or fungi that feed on it and then bring back samples under controlled conditions. These species would then be tested against Australian native plants and commercial species and those imported species that do not predate upon those would then be tested for survivability in the regions most affected by the weed species. Once the optimum control species are found they are released into the environment to control the weed species.

      Although this is by far the most cost effective method of control it often not very popular in capitalism first, last and everything in between countries as there is no opportunity for profit in the solution as it must be given away free, to spread on it's own.

      ECOLOGICAL THREAT Cogon grass can invade and overtake disturbed ecosystems, forming a dense mat of thatch and leaves that makes it nearly impossible for other plants to coexist. Large infestations of cogon grass can alter the normal fire regime of a fire-driven ecosystem by causing more frequent and intense fires that injure or destroy native plants. Cogon grass displaces a large variety of native plant species used by native animals (e.g., insects, mammals, and birds) as forage, host plants and shelter. Some ground-nesting species have also been known to be displaced due to the dense cover that cogon grass creates.

      Also, it won't just stay together in a patch but it reaches out. WP dixit:

From nature's point of view--assuming it had one--this weed is a success, and the more rapidly it extends its range the more successful it will be.

Not only do new species show up now and then without human intervention, environmental conditions change, and species-interactions occur, that prevent anything remotely resembling stability beyond the very basic level required for the moderately long-term persistance of life.

    And it seems that you believe that because absolute statism is impossible, all changes are equal.

    No there's no such thing as "balance" as some kind of permanent thing. Yes ecosystems change without human intervention. But when stated as such absolutes, these statements are essentially meaningless. You are quite deliberately not drawing a distinction between the mountains eventually eroding, and them being bulldozed into the ocean in a week.

    If you don't take a literal absolutist definition of "balance" as "statism", then it's obvious that there is a balance in our ecosystems. Yes they change, borders between ecosystems move, species adapt, yet these things all happen together, maintaining over time a balance despite change. Because they aren't mutually exclusive opposites in the real world of shades of gray. The whole reason why these introduced plants are a problem is because they didn't evolve here. Thus their impact in this ecosystem clearly differs from that of any organism that did evolve here, or with their impact in the ecosystem they did evolve in.

    That is the kind of balance we're talking about. Not an absolutist balance, but the natural kind where species co-evolve. No you can't maintain anything like this over the long term in the face of ice ages and other geologic/climate changes, no you can't prevent any species from ever being introduced to an environment where it did not evolve and has a disruptive effect, but that's fine, nobody is saying we must. But there's a reason the last major extinction event occurred after humans arrived, with millennia of relative stability before even in the face of advancing or retreating glaciers.

    So just because change is inevitable, that does not mean we humans should not try, nor be concerned with, avoiding being the instrument of rapid and destructive change. That's a foolish, irresponsible view which is what absolutism always is.

    If you value ecosystemic "balance" then you should be rooting for the weed (as it were) because the sooner humans stop interfering with its spread the sooner a new quasi-equilibrium will be established.

    Ridiculous, as the shortest path to "quasi-equilibrium" is to return to the one that the introduction of this weed by humans disturbed. Introduce an invasive species, then don't "interfere" with it -- this is exactly the kind of thing this strawman-based absolutist "logic" leads to.
