English Ivy (Hedera spp., Araliaceae) Response to Goat Browsing

  • Claudia S. Ingham (a1) and Michael M. Borman (a2)


English ivy is an exotic liana that invades forests by forming dense monocultures on forest floors and by climbing trees. In this study, we evaluated the effectiveness of high-intensity–short-duration goat browsing to control English ivy in the Willamette Valley of Oregon. Species composition and percent cover were determined in August 2006 before the first browsing treatment and before and after treatments in 2006 and 2007. A final assessment was made in July 2008. Browsing effects were evaluated by comparison of multiple means statistical methods. English ivy cover declined significantly in samples browsed once or twice compared with untreated samples. The difference between levels of browsing was also significant, indicating that repetition of browsing for a second year is effective. Species composition change was minimal, with the appearance of sword fern and removal of Himalayan blackberry from 2006 to 2008.
