Invasives

Today we went on an invasive walk with Tom Lee, one of the wonderful ecologists that teaches at UNH. He gave us several key definitions to apply to plants in the area:
Native Species: The species have been around since before Europeans arrived.
Non-Native Species: These species were brought to this region from somewhere else; synonymous with exotic, meaning from somewhere else.
Finally, we have invasive species, meaning that it is a non-native species that affects the surrounding habitat in a negative way. This negative effect can be environmental or even economic.

Ginkgo, non-native/exotic
Bittersweet, non-native/invasive
Low-Bush Blueberry, native
Bayberry, native
Red Canary Grass, non-native/invasive
Wild Carrot, non-native
Multiflora Rose, non-native/invasive
Burning Bush, non-native/invasive
Norway Maple, non-native/invasive
Norway vs. Sugar maple leaves. Norway Maple leaves have more pronounced bottom lobes.
Japanese Barberry, non-native/invasive
Glossy Buckthorn up close.
Norway Maple bark up close, showing the lattice-like pattern.
Extensive Glossy Buckthorn, clay soil.
No Glossy Buckthorn on opposite of path, loamy soil.
Jewelweed, non-native/invasive
