Brushing boots really works to keep weeds on site


Why clean your equipment after a long exhausting day controlling noxious weeds? One of the primary modes of weed dispersal is seeds or other propagules hitching a ride on boots, shovels, pant legs and paws.

Brushing dirt off of boots to prevent spread of weeds

In the case of garlic mustard, the seeds are very small and dark and are not going to be visible when they are hiding in the dirt. The picture below illustrates the number of garlic mustard plants that might have been transferred to a new site, had the crews working at this site not taken the precaution of sitting down on this log and cleaning off their boots and equipment before leaving. In this case, the garlic mustard did not leave the infested site with the crew.

Garlic mustard seedlings line this log where boots were brushed after workers were in garlic mustard infested areas.

If we are to prevent noxious weeds from spreading, everyone working in weed infested sites will need to make this a part of their regular routine. The time and energy it takes to thoroughly clean your boots and equipment on site is a small price to pay for the time, expense and heartbreak of finding and controlling a whole new site.

Engineering: See It, Solve It!

Students take a quiz about their knowledge of native plants and noxious weeds, part of the STEM conference on Feb. 9, 2017

“Engineering: See It, Solve It” was the theme of the Feb. 9, Enumclaw STEM Expo. And since Science, technology, engineering and math are the cornerstones of the work done in the Water and Land Resources Division, naturally we were there to spark the interest of the next generation of our workforce.

As seen in this photo, many of the more than 3,000 attendees took the “Noxious or Native Quiz” to see if they could identify plants in their environment.

The Stormwater Services team showed kids how they map King County’s stormwater system digitally and did some hands-on water sampling demos with equipment to show how they manage stormwater and improve water quality.

King County’s Noxious Weed Program and Stormwater Services teams were two of more than 70 exhibitors that included Boeing, Fred Hutchinson Science Education Partnership, Pacific Science Center, Association of Chemical Engineering Graduate Students and the King Conservation District.

See it? Report it! Washington Launches an Updated Invasive Species Reporting App

Reposted from Noxious Weed News

Washington’s invasive species reporting app just got smarter. Now anyone can use their smart phone or other device to easily report sightings of invasive plants, animals and other pesky organisms anywhere in Washington State and be sure that information will go to the right agency.

Download WA Invasives for free at Google Play Store and Apple iTunes App Store.

This app produced for the Washington Invasive Species Council is easy to use and, more importantly, communicates directly with the agencies who are tracking invasive species of all sorts. You don’t have to figure out who to contact when you notice an unusual plant, insect or other organism. Just enter information on what you see and a photo through the app and the report will be made available immediately to the council and its network of experts through an automated alert.

According to Justin Bush, executive coordinator of Washington Invasive Species Council, “This streamlined process will enable invasive species managers in Washington State to more quickly respond to new invasive species sightings. When it comes to successfully eradicating invasive species, early detection and a rapid response is key.”

Recording a new giant hogweed infestation in March the old-fashioned way, with a pen an paper. Now this can be done quickly with the WA Invasives phone app.

Once experts verify a mobile app report, it becomes part of the Early Detection and Distribution Mapping System (EDDMapS), from the University of Georgia’s Center for Invasive Species and Ecosystem Health. EDDMapS is a Web-based mapping system that provides real time tracking of invasive species occurrences, and local and national distribution maps, available for viewing at EDDMapS contains more than 3 million invasive species occurrence reports made by 35,000 users across North America. This comprehensive view of invasive species locations helps to guide policy, research and decisions at local and international levels.

According to Chuck Bargeron, associate director for invasive species and information technology at the University of Georgia Center for Invasive Species and Ecosystem Health, “EDDMapS aggregates data from many sources, professional and citizen scientists alike, through bulk data uploads, Web reports and smartphone reports into a database.”

By using the WA Invasives app, we can all do our part to catch new invasive species while we still have a chance to stop them.
