野生动物机构和生物控制研究人员和从业人员之间的长期争论涉及Diorhabda carinulata Desbrochers（鞘翅目：叶甲科），以抑制入侵的柽柳属物种。类似于Tamaricaceae），以及在西部河岸生态系统中，柽柳落叶对濒危的西南杨柳捕蝇草的潜在影响。冲突和随后的法律的行动目前集中在D的存在。在维珍河流域的霸鹟的繁殖范围内发现了carinulata，这导致APHIS终止了支持生物防治开发计划的许可证，也影响了开发针对环境杂草的生物防治剂的其他计划。对野生动物的关注的核心是缺乏生物防治预期的原生植被恢复，因此目前和计划中的努力是促进原生棉白杨-柳树栖息地的恢复，以减轻预期的柽柳覆盖率下降。河岸恢复的战略方法概述，可以促进可持续的，科学记载的恢复这一标志性的栖息地类型。虽然这些努力的结果将不会立即知道，这是导致河岸恢复的过程中，从双方的辩论，通过合作寻求解决方案的专家聚集在一起，如果成功的话，可能会允许重新启动的柽柳生物控制计划伴随着栖息地改善野生动物物种的保护问题。
A long-standing debate between wildlife agencies and biological control researchers and practitioners concerns Diorhabda carinulata Desbrochers (Coleoptera: Chrysomelidae) introduced to suppress invasive Tamarix spp. similar to Tamaricaceae), and potential impacts of Tamarix defoliation on endangered southwestern willow flycatchers using this non-native plant as nesting habitat in some western riparian ecosystems. The conflict and ensuing legal actions are currently centered on the presence of D. carinulata within the breeding range of the flycatcher in the Virgin River watershed, which has led to APHIS termination of permits supporting the biocontrol development program and has also affected other programs to develop biocontrol agents against environmental weeds. Central to concerns over wildlife is the lack of rehabilitation of native vegetation where biocontrol is expected, so there are current and planned efforts to promote restoration of native cottonwood-willow habitat to mitigate the anticipation decline in Tamarix cover. A strategic approach to riparian restoration is outlined which could facilitate sustainable, and scientifically documented recovery of this iconic habitat type. While the results of these efforts will not be known immediately, the process which is leading to riparian restoration has brought specialists from both sides of the debate together in search of resolution via collaboration, and if successful, may allow re-initiation of the Tamarix biocontrol program attendant with habitat enhancement for wildlife species of conservation concern.
