Each year, with the help of numerous partners across thirteen states and Mexico, RiversEdge West produces an annual distribution map that notes the presence and absence of Diorhabda spp. from sampling sites across the west. The links below contain all archived tamarisk beetle maps spanning over a decade.
These data in no way represent all locations where the tamarisk beetle may exist, but give a broad perspective of beetle establishment and dispersal, providing land managers with information that may help with their integrated pest management plans, restoration strategies, and funding opportunities.
If you would like to track the tamarisk beetle and to aid in data collection in North America, please visit our Applied Science page.
