Differentiating existing habitat of the invasive tamarisk (Tamarix spp.) from potential habitat of the endangered Southwestern Willow Flycatcher (Empidonax traillii extimus) through maximum entropy modeling
MetadataShow full item record
Biological control of the exotic plants known collectively as tamarisk (Tamarix spp, saltcedar, tamarisk) in southwestern states is controversial regarding the protection of the federally endangered Southwestern Willow Flycatcher (Empidonax traillii extimus). The songbird sometimes nests in tamarisk where floodplain-level invasion replaces native habitat. Biological control with the saltcedar leaf beetle (Diorhabda elongate) began along the Virgin River, Utah, in 2006, enhancing the need for comprehensive understanding of the tamarisk-Flycatcher relationship. I used maximum entropy (Maxent) ...
