The Center for Biological Diversity (CBD) recently released a report (A menace to monarchs) describing the threat to monarch butterflies posed by an increased use of dicamba.  While I have been fairly critical of the Xtend system1 due to off-target movement of dicamba and subsequent injury, I think CBD has exaggerated the threat to monarchs posed by dicamba.  I would like to make it clear that while I think their analysis is flawed, I do believe additional restrictions on dicamba use are required to minimize risks associated with volatilization.

Learning About Iowa Monarchs

We want our recommendations for monarch habitat improvement to be scientifically sound. Research projects in summer 2017 include:

  • efforts to evaluate nine species of milkweed on plots at Iowa State University research farms
  • a project to discover optimal monarch breeding, forage and roosting habitat characteristics in Iowa's patchy landscape and
  • a survey of milkweed species and monarch occurrence, plant density, and population to establish baseline data.
