The salt cedar beetle as the best environmental friendly solution to the salt cedar tree issue in ne
Tamarisk, also called salt cedar because it exudes salt into the soil, spread like wildfire. The mean SC values reached 0.
But they are still losing ground to the sprawling tree. Although Grand Canyon was not participating in the test project with the beetles, the staff recognizes the park doesn't exist in a vacuum. Arthropods such as ladybird beetles, assassin bugs, stink bugs, preying mantis, spiders, and ants, tended to keep beetle numbers down, said Tom Dudley , a riparian ecologist at the University of California at Santa Barbara. Many of these species are known for being water hogs, taking more out of the river than native species such as willow. Researchers previously thought that this species of the tamarisk leaf beetle would restrict its range to above the 38th parallel, which is near the upper end of Lake Powell. George, those flycatchers nesting in tamarisk did a very interesting behavioral switch last year to nesting in the willows. That group and the Colorado Department of Agriculture are collaboratively monitoring the tamarisk beetle in Colorado, Utah and Arizona. The answer may hinge on efforts by resource managers to speed the return native species to areas that have been dominated by the invasive plants for decades. The beetle populations, however, kept spreading. She says her team is about a year out from being fully prepared to plant native trees in the wake of tamarisk, which could die out after just a few seasons of beetle feeding. Growing infestations of the tamarisk leaf beetle in Grand Canyon may defoliate and kill tamarisk trees that now dominate the river corridor. Dan Bean of the Colorado Department of Agriculture, the small population of beetles recently documented in Grand Canyon National Park is unlikely to overwinter successfully. Tim Carlson, Tamarisk Coalition Research and Policy Director, notes that, "Monitoring of beetle movement and vegetative response are critically important, not only to understand the direct and indirect impacts of the beetle on riparian ecosystems, but in order to implement adaptive management activities aimed at re-establishing native vegetation.

See pictures of Grand Canyon National Park. Check back in a few years for the answer. One which has shown promising results is the tamarisk leaf beetle Diorhabda spp.

During monitoring, small numbers of beetle larvae were found on tamarisk trees along both sides of the river corridor beneath Navajo Bridge and Fish and Wildlife Service , no beetles were released within miles of nesting locations for the southwestern willow flycatcher, a bird endangered since that now appears to rely on tamarisk trees, nesting in them even when native trees are still around. Researchers previously thought that this species of the tamarisk leaf beetle would restrict its range to above the 38th parallel, which is near the upper end of Lake Powell. Furthermore, without native trees to fill in the gaps left by dead tamarisk, other weedy invasives, like Russian knapweed, Russian thistle, pepperweed, and camelthorn, could take up occupancy. Lori Makarick, the Vegetation Program Manager at Grand Canyon, says the park plans to continue their current program of tamarisk control, but the project may take on a different dimension in future years. It was approved for release as a biological control agent in certain areas of the west in Peruvian Amazon weevil grubs, which live inside rotted aguaje palms, are charred over an open flame; lush from feeding on palm tissue and oil, they quickly caramelize. One which has shown promising results is the tamarisk leaf beetle Diorhabda spp.
Will this prove to be a case of "Oh, my," or "Oh, me"? George, those flycatchers nesting in tamarisk did a very interesting behavioral switch last year to nesting in the willows.
