Volunteers Pull Tackweeds at Pasco's Chiawana Park

Posted: Updated:

PASCO, Wash.-- Volunteers went to work Saturday clearing Chiawana Park in Pasco of tackweeds.

It's part of the Great American Tackweed Pull to remove the pesky and thorny weeds from parks and trails.

The weed can prick tires and shoes.

One tackweed plant can produce between 200 and 5,000 seeds.

Pulling the weeds helps to prevent the quick spread of the invasive plant and bothersome plant.

"Outdoor activity, if you've got the tackweed along the path, it kind of discourages it. If we can get out here and remove those tackweeds with a little bit of effort, doesn't take a whole lot of effort, it's a good deal," said Dave Gerkensmeyer, volunteer.

Tackweed seeds can stay in the ground for up to seven years.

Volunteers want to pull them out of the ground to protect local parks and the over 240 miles of trails in the Tri-Cities.
