by rachel charlton cottonwood, arizona \u2013 fighting nature with nature seems like a good idea \u2013 unless nature doesn\u2019t care about geography.<\/p>\n today, the effects of a federal decision made 20 years ago to use asian beetles to slow the spread of an invasive shrub across the west are reducing nesting habitat for an endangered songbird \u2013 the southwestern willow flycatcher.<\/p>\n the u.s. department of agriculture\u2019s animal and plant health inspection service, introduced tamarisk leaf beetles from china and kazakhstan around the west to kill tamarisk trees, also known as salt cedars. some of the beetles were released near moab in eastern utah.<\/p>\n \u201cthe goal of their program was to control tamarisk,\u201d said greg beatty, a biologist with the u.s. fish and wildlife service who has led flycatcher recovery efforts since 1999. \u201creduce it. kill some plants. i don\u2019t think they anticipated that it would kill all tamarisk, but that it would reduce its abundance.\u201d<\/p>\n the beetles did their job, stripping the tamarisk of its feathery, green canopy, which often kills this fast-growing deciduous shrub. the tamarisk was introduced in the 1800s<\/a> from eurasia as an ornamental, for use in windbreaks and as a way to control stream-bank erosion.<\/p>\n the aphis program wasn\u2019t supposed to release beetles within 200 miles of where southwestern willow flycatchers nest. the birds can be found throughout the west; in arizona, around roosevelt lake and along the upper gila river. experts calculated even if the beetles migrated south toward arizona, the bugs would not survive the difference in climate.<\/p>\n
