During presettlement times, fire-sensitive species such as Tsuga canadensis and Picea rubens appear to have been most common in low protected areas of the central uplands (Foster and Zebryk 1993), while species such as Quercus rubra
and Castanea dentata may have occurred on drier exposed sites (Whitney 1793).

The upland forests are dominated by Acer saccharum, Tagus grandifolia, and Quercus rubra
, and the lowland forests are dominated by Abies balsamea, Acer rubrum, Betula spp.
Project actions also seek to remove invasive alien species (Prunus serotina, Quercus rubra
, Rhododendron ponticum) from habitats including those that support oak woods hosting Quercus robur.

This conclusion was corroborated by Crow (1992), who studied a six-year-old cohort of Quercus rubra
seedlings growing under a variety of site conditions and found that resprouting occurred in 22% of the seedlings when no overstory was present, in 20% of seedlings under a partial overstory, and in 13% of those under a complete oversto ry.
Before the manipulation, both areas were structurally and compositionally similar and were dominated in basal area by Quercus rubra
and in density by Acer rubrum (Table 1).
