Plants

The Chestnut Oak Forest has the look of a rugged survivor, with its sparse vegetation and the twisted branches of mountain laurel. Species diversity is low—you’ll see mostly chestnut oak trees and mountain laurel. In some places, the soil is so dry, infertile, and matted with roots that mosses and reindeer lichen may be the only things growing on the forest floor.

What’s missing? American chestnut may have been an important part of the canopy in years past. Ecobit: Chestnut Sprouts: Phantoms of the Past

Canopy Trees

The trees whose crowns intercept most of the sunlight in a forest stand. The uppermost layer of a forest.

Understory Trees

Small trees and young specimens of large trees growing beneath the canopy trees. Also called the subcanopy.

Shrubs, Saplings, and Vines

Shrubs, juvenile trees and vines at the right height to give birds and others a perch up off the ground but below the trees.

Low Plants (Field Layer)

Plants growing low to the ground. This includes small shrubs and tree seedlings.

Non-Native Invasive Plant Species

The extremely dry, acidic soil here is not very welcoming to non-native plants.

Animals

Even though natural communities aren’t named after animals, animals do play a crucial role in maintaining natural communities. Plants and animals need each other. To name just a few examples, plants provide food and habitat for animals, and animals help plants reproduce by spreading pollen and seeds.
