Japanese climbing fern

Lygodium japonicum

Origin: Asia

Impact: Japanese climbing fern is an invasive climbing fern that is changing the landscape of East Texas. Introduced as an ornamental, it has escaped and is now rapidly spreading across the forested areas of Eastern Texas smothering native trees and shrubs. At least 15 new East Texas counties have reported the presence of this fern since 2005. Not only does it impact native vegetation directly, but is a significant fire hazard. The dead fern fronds serve as a fire ladder to carry fire to the crown of trees.

Please report any infestations of Japanese climbing fern you observe, particularly in counties not highlighted on the distribution map.
