The emerald ash borer (EAB) is a highly destructive invasive beetle which attacks and kills all species of ash, but not mountain ash, which in spite of its name, is a completely different species of tree. To help prevent the spread of EAB, the movement of ash logs and firewood out of regulated areas is restricted. Report any detections outside of regulated areas to one of the CFIA's offices.

NAISMA’s minimum mapping standards for invasive weeds addressed the minimum base information necessary to compare and combine invasive weed maps across tribal, county, state/provincial, national, and even international borders.

A newly developed index identifies areas of the Mediterranean Sea which are most affected by non-native, invasive alien species introduced through the Suez Canal, by aquaculture or through shipping. The top invaders appear to be algae, according to the JRC study. The Cumulative Impact of Invasive Alien species (CIMPAL) index calculation brings together datasets on IAS distribution with literature information on the impacts of IAS on biodiversity.

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."
