The Eastfork Forest contains pine trees, birch trees, and dogwood trees. All of the trees in this forest are considered a(n) .

these forests are rather simple, generally consisting of two layers: an overstory and understory. Some forests may support an intermediate layer of shrubs. Pine forests support a herbaceous understory that is generally dominated by grasses and herbaceous perennials, and are often subject to ecologically important wildfires. Many species of tree inhabit these forests including cedar, cypress, Douglas fir, fir, juniper, pine, podocarpus, spruce redwood and yew.

the organisms are not adapted to live in some communities or habitats.
