The Washington Invasive Species Council, state agencies and researchers are calling for a census in May to help determine the location of Scotch broom throughout the state. "We need everyone's help to size up the problem," said Justin Bush, executive coordinator of the Washington Invasive Species Council. "Without baseline information about the location and population size, we don’t have enough details to determine solutions. The information from the census will help us set short- and long-term action plans." Yellow flowered, Scotch broom is hard to miss when blooming. It can be found in 30 of Washington's 39 counties (PDF | 282 KB). While known to be spread across the state, specific locations and patch sizes are not well documented, leading to the council's call for a month-long census.
"We're asking people to send us information from their neighborhoods," Bush said. "The information can be transmitted easily to the council by using the Washington Invasives mobile app or by visiting https://invasivespecies.wa.gov/report-a-sighting/. Sightings should include a photograph of the plant that shows enough detail that the plant can be verified by an expert. A description of the size of the patch is also helpful, such as whether the patch is the size of a motorcycle, a car, a school bus or multiple school buses. Photographs also can be shared with the council on Facebook, Instagram and Twitter by using the hashtags #TheGreatScotchBroomCensus and #ScotchBroom2020Census."
