Garlic mustard displaces native forest under story species, reducing diversity and decreasing forage availability for deer. Frequently invaded habitat types include forest opening edges, roads, streamsides, trails and agriculture land; it thrives in the partial shade. Displacement occurs rapidly, often within 10 years of establishment. This plant is very difficult to control once established.
East Multnomah Soil and Water Conservation District has again provided a dumpster for disposing of pulled and bagged garlic mustard. It is located at the old grade school site on the Historic Highway in front of the ball field across the street from the Corbett Water District. It is marked GARLIC MUSTARD DUMPSTER. A tracking sheet is located below it. Please fill out all information requested so they can track how much time was spent pulling garlic mustard and where it came from. Only use this for disposing of garlic mustard! Email questions to firstname.lastname@example.org or call 503-935-5363.
[ To the left is John Cowan, with Oregon State Parks, explaining Garlic Mustard to a group of kids from the Corbett Grade School who spent time pulling Garlic Mustard by Latourelle Falls on April 29, 2010 ::: When you pull Garlic mustard - be sure to grab low on the stalk and wiggle to loosen the roots. Make sure the flower head ( where the seeds are ) gets put completely into a garbage bag - or it can just spread the seeds. The roots of this plant create a toxin that actually kills off its neighbors and allows it to spread more easily. ]
