Progress: Smartphone apps for weed control

LAWRENCE, Kan. — Online databases and new smartphone applications are making it easier than ever to track and map infestations of invasive weeds.
“These new resources are moving pockets of information out of universities and laboratories and into the public domain where they are readily accessible,” said Lee Van Wychen, Weed Science Society of America science policy director.
“Now scientists, policy makers and even the general public can use the data to track the location and movement of weeds and monitor the effectiveness of management strategies.”

Building database

Online weed databases are currently maintained by a variety of public agencies, organizations and educational institutions.
Examples include: Global Invasive Species Information Network (www.gisin.org), administered by the National Institute for Invasive Species Science of the U.S. Geological Survey Fort Collins Science Center. iMapInvasives (www.imapinvasives.org), managed by The Nature Conservancy. Invasive Plant Atlas of the MidSouth (www.gri.msstate.edu/ipams), managed by the Mississippi State University Geosystems Research Institute. National Institute for Invasive Species Science Database (www.niiss.org), hosted by the U.S. Geological Survey Fort Collins Science Center. Plants of the United States (plants.usda.gov), managed by the USDA’s Natural Resources Conservation Service.

Report sightings

New technologies are also making it easier than ever to capture and report information on the location of weeds so that online databases are more complete.
One example: iPhone and Android applications have been developed by the Center for Invasive Species and Ecosystem Health at the University of Georgia in support of EDDMapS — an online Early Detection and Distribution Mapping System for invasive species.
Previously, weed sightings were submitted to EDDMapS using detailed online forms. But the new applications are game changers. Now home gardeners, backpackers and other laypeople likely to encounter invasive weeds can participate as well.

Powerful, but easy

“The apps are really fun and easy to use,” said Karan Rawlins, invasive species coordinator at the Center. “You simply use your phone to take a picture of the weed, and the application grabs the GPS coordinates automatically. Estimate the size of the infestation, press send and your sighting goes out for validation by state and local experts.
“It’s so easy that I’ve actually rolled down my window while stuck in traffic to snap a photo and report weeds spotted along the side of the road.”
EDDMapS apps for iPhone, iPad and Android devices can be downloaded for free at apps.bugwood.org.
Specially tailored versions were created for Florida, the Southeastern U.S., the Mid-Atlantic region and the Missouri River watershed.
Weed tracker. The data reported to EDDMapS is available at no cost to researchers, educators, land managers and others interested in tracking and managing invasive species. It can be searched, queried and downloaded in a variety of formats to evaluate weed distribution for a given locale.
“If you want to collect information on weeds growing in a local park or schoolyard, you simply create an account and download data for that location,” Rawlins said. “You can view the results on an interactive map, download them into an Excel file, sort by species and track infestations over time.”
The EDDMapS project is supported by the U.S. Forest Service, the National Park Service and the U.S. Fish and Wildlife Service.
