My research has recently focused on monarch butterfly conservation. Along with a colleague I was able to show that the almost 90% decline in the size of the monarch population was due primarily to the loss of milkweeds, the monarch's larval host plant. The loss of milkweeds was in agricultural fields and was the result of the application of the herbicide Roundup to GMO corn and soybeans that were resistant to Roundup (Roundup Ready). We are now working on the best techniques for adding more milkweeds to the landscape.
