Coyote Gulch links to a hopeful piece of news: a biological control for the invasive, wildlife-habitat-destroying tamarisk may just be working. (Newspaper link may expire.)
From the Rocky Mountain News:
Releases in 2001 at four sites, two in Nevada and two in Utah, have matured and beetles are defoliating hundreds of acres of tamarisk. . . . beetles released in 2004 near Moab, Utah, are taking hold.
The tamarisk, a tree native to Eurasia, has crowded out native species such as willows and cottonwoods and sucked up vast amounts of water in the West.
Labor-intensive efforts to eradicate tamarisk cost $1,500 to $3,000 per acre. The tamarisk leaf beetles may be able to do the job for less than $10 per acre, according to U.S. Bureau of Land Management spokeswoman Mel Lloyd.
