The staff and board of the North American Invasive Species Management Association review invasive species headlines each month. This helps us stay on top of trends and further our mission to support, promote, and empower invasive species prevention and management in North America. We then share invasive species news most relevant for people who manage terrestrial and aquatic invasive species across the the United States, Canada, Mexico and the world.

Tool Predicts which Native Fish Species are Most at Risk from Lionfish Predators

Global/Alberta — Read on Phys.org

Coastal countries have between two and five years to act to protect native fish species once voracious lionfish arrive in their waters, according to a University of Alberta ecology professor who helped create a tool to predict which fish are in danger.

A Kansas boy entered a unique insect at the state fair. It triggered a federal investigation.

The boy told government officials he found the dead lanternfly on his patio in May, according to Erin Otto, national policy manager for the USDA’s Animal and Plant Health Inspection Service. Because adult lanternflies usually start emerging in July and the specimen was “worn and desiccated,” officials said the boy’s insect may have died last year, Otto wrote in a statement to The Post.

Diversity Challenge Confronts Ecology

Global — Read in Ecological Applications

“The Diversity Challenge Confronts Ecology” Forum published in this issue of Ecological Applications presents perspectives on structural and cultural problems within institutions, mentorship practices, professional development programs, and research experiences which have caused and perpetuated low representation of African Americans, Hispanic Americans, Native Americans, and Pacific Islanders in the environmental workforce and in academia. 

The moth Lymantria dispar asiatica (adult female shown here) has been unintentionally introduced to North America several times in the last few decades. Through a complex monitoring and management program, officials have been able to prevent this pest from establishing in North American forests. A new report in the open-access Journal of Integrated Pest Management gives an inside look at this success. Photo by John Ghent, Bugwood.org.
