Invasives education is part of our new initiative to combat the growing problem of non native plants in our natural
areas. We hope to inform the public about the impact of these plants and to encourage volunteers to join us in our efforts
to control them. The management of these invasive plants is a key component of the Forest Stewardship Plan.
BASICS: Plants, insects, animals taken out of their natural habitat
may not have the natural predators and diseases that previously kept their population under control. So they
are able to agressively compete with native species for space , light, water and nutrients and spread through the forest
displacing our native species. In our area for example deer will browse on native plants and rarely eat non
native food sources.
Norway Maple - Acer platanoides First brought
to the US in 1762, reportedly in the Philadelphia area, this tree is one of the top priority species listed for treatment
and removal at Monocacy Hill. This tree produces many seeds and can spread quickly displacing native trees and hindering
understory growth. It is very similar to the sugar maple, but has a shiny underleaf and milky sap. Tagging,
removal and treatment are planned to control the further spread of of Norway Maples.

For the past two years we have been involved in a project with
the Pa Dept of Agriculture to eradicate Ailanthus trees in the park. This tree is the main food source for
the spotted lanternfly, Ailanthus is also a non native invasive tree.
Whenever we remove non native trees, we replant that
area with native tree seedlings.
Japanese Honeysuckle (Vine) - Lonicera japonica
