Tillamook volunteers battle English Ivy

 

SALEM - Oregon Department of Fish and Wildlife officials today announced
a May 7 event in Tillamook to remove invasive ivy plants.

 

Volunteers will work from 9 a.m. to noon at ODFW's Tillamook River
Tidewater Fishing Access and Wetland site, located along the Netart's
Highway just west of Tillamook. 

 

This Saturday's event marks the third annual "No Ivy Day." Hedera helix,
also called English Ivy, was originally used for landscaping. It now
infests more than 25,000 acres of parks and natural spaces in the metro
region and nearby areas.

 

Unchecked ivy shrouds and kills trees, causing reduced forest canopy.
English Ivy has become a menace due to its popularity as a landscaping
plant, its climbing habit, and because seeds are spread by birds. Ivy
has become widespread in natural areas and unmanaged green/open spaces,
where it buries native groundcover vegetation and climbs and kills or
topples matures trees.

 

English Ivy vines attach to the bark of trees, brickwork, and other
surfaces by way of numerous, small root-like structures, which exude a
glue-like substance. Older vines are known to reach a foot in diameter.
Leaves are typically dark green, alternate and simple (the leaf is not
composed of little leaflets). Juvenile leaves are 3-5 lobed but mature
leaves or leaves in full sun are ovate (roundish) to rhombic (angular
but not square).

 

To participate in Tillamook's No Ivy Day, call Michelle Long at
503-842-2741. For more information on English Ivy, visit the The No Ivy
