Tamarisk control suddenly drops in importance according to new federal policy

Tamarisk (Tamarix spp., aka Salt Cedar), a non-native invasive shrub spreading throughout the American Southwest, has been judged to be no greater usurper of water than its native counterparts while still offering nesting habitat, so a program to introduce the Tamarisk Beetle (Diorhabda spp.) to set back the shrub has been halted by the U.S. Department of Agriculture. The decision affects bio-control efforts in 13 states. Read about the origins of the program here, and read the June 20, 2010, update here.
