Report #2652 - Report: Garlic Mustard (Alliaria petiolata)

Garlic Mustard (Alliaria petiolata) on May 1, 2019

Submitter has sample
EDRR Status: Population treated

Description of specimen

See above. Garlic mustard was in bolting phase, mostly still with flowers, not seed pods. One clump looked like it might have already been treated with herbicide. I hand pulled, bagged, and threw away both clumps.

Commentary

None

Location

Disturbed roadside, mostly shaded, flat area. Found 2 small clumps of garlic mustard (3 plants in each clump) on westbound Capitol Hwy/OR 10. Clumps were immediately adjacent to the bike lane, and maybe 100-300ft apart. Plants were closest to the intersection of Capitol Hwy and Barbur Blvd, though there could be more anywhere on this stretch between Barbur and Terwilliger Blvd (I checked this whole stretch and couldn't find more than the 2 clumps, but definitely might have missed some).
