 depending on the presence or absence of large trees. The general 

 aspect of the two series was quite similar in respect to actual species

The Woods. 



The flora of the woods may be divided into the following four 

 groups : trees, shrubs, herbs and fungi. While numerous species 

 were found in each group, the majority of individuals belonged to a 

 few species which stood out from the remainder of the vegetation. 

 Among the trees, the red maple (Acer nibriim) was the dominant 

 species. This together with the oaks (Qiiercns palustris, Q. rubra 

 and Q. alba) contributed over half the trees in the woods. Clumps

 ambar styraciflna) and the beech (Fagits grandiflora) added another 

 quarter. Clumps of gray birch (Bctida poptdifolia) in various stages 

 of decay indicated that this species was an important eleinent before 

 the taller oaks and maples attained their maximum height and cut off
