Online Maps Communicate Gypsy Moth Treatments to the Public
By Mike Dolbow and Erich Borchardt, Minnesota Department of Agriculture

Ranked among America’s most destructive tree pests, gypsy moth has caused millions of dollars in damage to forests as it has spread from New England to Wisconsin in recent decades. The Minnesota Department of Agriculture (MDA) maintains a statewide monitoring program to watch for start-up infestations, and when an infestation is found, the department moves in to eradicate the pests before they can spread.

In 2010, the program detected several infestations in the Twin Cities metro area and in the Arrowhead region. MDA and local officials are developing plans for eliminating these infestations before they can spread. Thumbnails and static PDF maps of the proposed Metro treatment areas are available from MDA on their website.  For residents and other stakeholders who wish to see the treatment areas on an interactive map, a “mashup” is available.

Lucia Hunt, supervisor of the MDA gypsy moth program, says “Online maps are a great tool for Minnesotans to quickly see if their properties will be affected directly by the gypsy moth treatments. The new statewide interactive map serves even more people, as now they can easily see if their travel plans overlap with treatment projects anywhere in the state.”

For MDA’s GIS staff, the interactive gypsy moth treatment map represents one of their first forays into integrating ESRI’s ArcGIS Server technology with Google Map’s basemap and geocoding services. Unlike MDA’s other interactive maps, it really only performs one function but it is quick, reliable, and easy to maintain.

The Minnesota Department of Agriculture has been monitoring for the presence of gypsy moth since 1973. Since 1995, between 10,000-25,000 traps have been set and monitored each year. The results of the trapping effort have driven over 400,000 acres of treatment, preventing the pest from gaining an early foothold in the state.
