Tamarisk may be not such a bad guy after all

cheap moncler outlet click to enlarge Pam Zubeck Tamarisk crowds out most other plants along the Arkansas River near the Kansas state line, but the plant isn’t the demon that some researchers have made it out to be, an Arizona biodiversity moncler sale outlet expert says. cheap moncler outlet

monlcer down jackets A couple Moncler Outlet of weeks ago, we ran a cover story (“Bushwhacked,” May 6, 2015) about the invasion moncler outlet store of tamarisk in the West and how it’s threatened water supplies and diversity in riparian areas. monlcer down jackets

moncler outlet store The other day, moncler outlet jackets we opened an email from Matthew Chew, an assistant research professor at Arizona State University, Tempe, with expertise in biodiversity, conservation, ecology moncler jacket sale and science policy. moncler outlet store

moncler outlet online He had somehow come across our story, and took us to the woodshed about a report that ignored a growing body of research that opposes the demonization of tamarisk as a water guzzler and wetlands destroyer. moncler outlet online

moncler outlet Like he related to us via email, “The majority of academics working on tamarisk study it in order to (a) complain about it or (b) try to find ways to get rid of it. That actually about sums up invasion biology. There are more and more heretics who start with the plant rather than the problem, but shift will be gradual at best. Especially since having a villain with no constituency is politically and bureaucratically convenient.” moncler outlet

cheap moncler coats I encourage you to dig a little deeper into the tamarisk story. So far you seem to have swallowed the Tamarisk Coalition view hook, line and sinker. As a result your articles are semi informed at best, and include statements of fact that moncler sale are not quite facts. cheap moncler coats

moncler sale outlet For example, all riparian plants (native or otherwise) use water pretty freely, so specifically indicting tamarisks for non beneficial water use is disingenuous. Unit for unit (plant, stem, volume of vegetation) they don’t use any more water than anything else. They’re just better than most cheap moncler jackets sale at waiting for it to arrive. moncler sale outlet

cheap moncler jackets Tamarisks are thriving in the west because they are very well adapted to the artificially altered hydrologies of our heavily exploited rivers. And tamarisk is not one species; at least nine species have been introduced and are hybridizing to evolve (and I’m using that term in its strictest biological sense) populations of new types that exist nowhere else some of which are more tolerant of high elevations or high temperatures than others. cheap moncler jackets

moncler mens jackets I’m moncler outlet uk attaching three papers you really need cheap moncler outlet to understand if you want to tell the tamarisk story well, rather than simply joining the chorus railing against the plants as if they were “the problem” and killing them was “the solution”. Tamarisks are likely here to stay, no matter how many beetles the Colorado’s insectary cranks out and how https://www.moncleroutletsite.com much Walton money the Tamarisk Coalition soaks up. Because the water use entailed by western economic development over the past century has incidentally amounted to a gigantic tamarisk housing project. moncler mens jackets

cheap moncler It seems logical to suppose that removal of Tamarix (or any plant that uses groundwater) should result in lower riparian water use and therefore higher flows in a river system, but empirical studies suggest otherwise. For example, a large scale, chemical eradication program initiated on the Pecos cheap moncler coats River in Texas in 1999 resulted in extensive mortality of Tamarix, but no documented increase in river flow as of 2003 (Hart et al. 2005). Various processes moncler outlet sale preclude the potential water salvages. Vegetation removal may raise the water table, but consequently produce more bare soil evaporation (Hu et al. 2006). Furthermore, it is moncler jackets outlet impractical to maintain bare floodplains and rivers banks. Cleverly et al. (2006) reported a one time annual savings of water when Tamarix and Russian olive (Elaeagnus angustifolia) were cheap moncler jackets removed from beneath Plains cottonwood (Populus deltoides) but projected the ET reduction to be short lived because of rapid understory regrowth. cheap moncler

cheap moncler sale Hopes that significant quantities of water can be salvaged for human use remain a prime motivation for Tamarix eradication schemes (Zavaleta 2000; Shafroth Briggs 2008), despite recent reviews and reports indicating that such actions offer no panacea for western water shortages and despite studies concluding that ET [evapotranspiration] rates show relatively small variability between Tamarix and other woody phreatophytes (Graf 1992; Shafroth et al. 2005; Owens Moore 2007; Nagler et al. 2008b). The studies suggesting that such a possibility were methodologically unreliable and moncler outlet online are now out of date moncler factory outlet cheap moncler sale.
