Volunteers Are Saving Dyke Marsh’s Trees
In 2021 in five sessions, as of April 4, 2021, FODM volunteers have collected 136 bags of English ivy off trees, an effort to save the trees.
English ivy (Hedera helix L.) is an invasive, evergreen, aggressive invader that can outcompete and smother native plants, block sunlight needed by herbs and seedlings and spread into the forest canopy.
“Vines climbing up tree trunks spread out and envelop branches and twigs, blocking sunlight from reaching the host tree’s foliage, thereby impeding photosynthesis,” says an NPS fact sheet. “An infested tree will exhibit decline for several to many years before it dies.”
Also, the added weight of vines can make the tree more vulnerable to blowing over during storms. It is also a reservoir for bacterial leaf scorch (Xylella fastidiosa), a harmful plant pathogen, says NPS.
Thank you to our many dedicated volunteers who have helped.
