Oops! Multi-State Release Of Non-Native Tamarisk-Gobbling Beetle Having Unforseen Consequences

Gosh, how could anybody have predicted that?!?!

:silly:

A foreign beetle imported to attack invasive trees in the U.S. Southwest may have brought its own culinary agenda. Researchers in Utah and Arizona are sounding the alarm about salt cedar leaf beetles, which were imported from Kazakhstan several years ago to control invasive tamarisk trees.

"Now that the beetle is spreading to large areas, we need to start looking for unexpected consequences of defoliation and death of the tamarisk," says Philip Dennison, a geographer at The University of Utah and lead author of a study warning of the unintended risks published this month in the online edition of the journal Remote Sensing of Environment.

Tamarisk trees, native to Europe and Asia, were first planted in the U.S. in the early 1800s as ornamentals and to stabilize soil, especially on riverbanks. The trees took off, and now dominate 1.6 million acres (650,000 hectares) of mostly riverside habitat throughout the Southwest. Dense tamarisk stands have crowded out native trees like cottonwoods and willows. And tamarisk gets a bad rap for being thirsty enough to drop water tables and dewater small streams—although the new research says the rep may be undeserved. Tamarisk was first identified as a pest around 1900, and biologists since the 1940s have implemented various control strategies, including herbicides, manual removal, and defoliation by goats and beetles. Total cost estimates approach $100 million for the decades-long efforts.

EDIT

As it turns out, tamarisk trees have a silver lining, Dennison says. Their sprawling branches, which are covered with long, pliable needlelike leaves, provide coveted cover for native birds. Among them the endangered willow flycatcher, which routinely nests in the tamarisk thickets that replaced the willow trees there. Salt cedar beetles were originally kept out of Arizona and New Mexico to protect the flycatcher, but researchers report that the beetles are now creeping from Utah's Virgin River into flycatcher habitat in southern Utah and northern Arizona. The Center for Biological Diversity (CBD), a Tucson, Ariz.–based conservation group, has filed a notice of intent to sue the USDA and APHIS to halt the beetle program, charging that the bugs have gotten out of hand and are threatening the endangered birds. Nate Ament, a restoration ecologist with the nonprofit Tamarisk Coalition in Grand Junction, Colo., says the greatest risk to streamside ecosystems comes in tamarisk's wake. The new satellite data show tamarisk-related water loss is lower than previously believed. If tamarisk trees are killed off by the beetles, newer weedy arrivals—like Russian knapweed, Russian olive and pepperweed—could hammer the water supply even more.

made it this long.

I'd be amazed if there was a single human being around in 5,000 years.

And it might be a lot quicker.

that someone, somewhere, won't be willing to give it a try. Preferably in a way that can't be reversed if things go wrong.

Not even close.

the stupids WILL take us into another depression. shit. in MI to get the INVASIVE emerald askh borer, BRING IN FOREIGN WASPS. WI is trying a native wasp to track the fucking ashborer that got into the state from some fucktard, but it was global china trade that BROUGHT in the fucking emerald ash borer. love of nikes is gonna kill us!

"Wahh-wahh-wahh!"
