In 2001, a USDA scientist released beetles to destroy an invasive tree, but they eliminated 94% of an endangered bird's habitat along one river

An invasive beetle introduced to control tamarisk trees has devastated flycatcher nesting grounds. This beetle, released by the USDA, successfully defoliated the invasive trees. However, flycatchers had adapted to nesting in these tamarisk trees after habitat loss. The beetle's actions reduced critical habitat by ninety-four percent in some areas. Restoration efforts now aim to re-establish native trees to support the endangered bird.
