New App Lets You Report Invasive Species

Feb. 23, 2015

COLUMBUS, Ohio -- Now there's a new tool for fighting alien invasions.

Your smart phone.

Ohio State University Extension has released a new app for spotting and tracking invasive species -- non-native organisms such as Asian carps, purple loosestrife and Asian longhorned beetle -- to try to keep them from setting up beachheads and hurting the economy and environment.

By using the free Great Lakes Early Detection Network app, a person can take pictures of suspected invasive species -- whether of farm, woods or water -- and upload the pictures and locations for verification.

Based on this early warning, scientists can send out alerts, map the spread and figure out a battle plan.

"Early detection gives us a greater chance of being able to handle infestations before they become so large that eradicating them isn't possible or feasible," said Kathy Smith, forestry program director for Ohio State University Extension and a co-developer of the app.

Data submitted by the app's users goes into the web-based Early Detection and Distribution Mapping System, which tracks the location and spread of invasive species throughout the U.S. and Canada.

The app divides sightings into the general categories of plants (including trees, vines, shrubs, herbs, grasses and forbs such as wildflowers), fish, insects, mammals, mollusks, crustaceans and plant diseases.

The network covers the states of Ohio, New York, Illinois, Indiana, Wisconsin, Michigan, Minnesota and Pennsylvania.

Aliens in the region already include cheatgrass, Chinaberry, round goby, garlic-mustard, tree-of-heaven, purple loosestrife, spiny water flea, emerald ash borer, hemlock woolly adelgid, Eurasian water milfoil, and zebra and quagga mussels, to name a few. The network tracks them all and more.

Meanwhile, Asian carps, which are more than one species, including silver carp and bighead carp, are close to but not in the Great Lakes themselves yet. Scientists say the fishes' impact on the lakes could be devastating.

The non-native emerald ash borer insect, for its part, has killed tens of millions of native ash trees throughout the eastern U.S. and Canada, has caused tens of millions of dollars in losses, and could wipe out every native ash in North America, according to a joint website by the U.S. Forest Service and several universities.

"Our native ecosystems are impacted in a variety of ways by non-native invasive species," Smith said.

"Early detection gives scientists time to explore some of the unknowns about a species and come up with strategies for dealing with an infestation."

The app is available for both Android and iPhone just go to 

The app's co-developers also included Eugene Braig, Marne Titchenell and Amy Stone, all of OSU Extension, and Chuck Bargeron of the University of Georgia's Center for Invasive Species and Ecosystem Health.

OSU Extension is the statewide outreach arm of Ohio State University's College of Food, Agricultural, and Environmental Sciences.

The Great Lakes Early Detection Network, according to its blog, "is a collaboration among multiple stakeholders working to rapidly respond to new invasive species sightings in the Great Lakes states. To accomplish this, we have developed a web-based alert system that emails users when new sightings for species or areas of interest are entered into our member data management systems."
