Beech

Fagus sylvatica

There is one beech in the park, in the southwest triangle. See Wikipedia entry here for the genus. A copper beech elsewhere in the Park died and was removed in July of 2020.

The maple trees in the Park withdraw all the green chlorophyll from their leaves, leaving the anthocyanins and other pigments in the beautifully colored leaves as those leaves separate from the tree and fall to the ground. Other trees are more stingy, and withdraw all the pigments from the leaves, so that dull brown leaves fall to the ground. Still others, like our copper beech and oak, hold on to those dead brown leaves over the winter. 
 
Marcescence is the scientific term for the retention of dead plant organs, usually leaves, that normally are shed. This occurs especially in the young trees, and you will notice that there are more dead leaves on our young beech than on our mature red oak, and more near the bottom of the tree than at the top. Why is this trait seen in the beech and the oak? They are related; they both belong to the same taxonomic family, and no other tree in the Park is in this family.
It is not clear of what advantage is marcescence to the survival of the tree. Theories are that it may discourage herbivores like deer or that it is allows the leaves to fall and act as fertilizer in the spring when the new trees are breaking seed. It is almost like a compromise between being an evergreen with leaf retention through the winter and being deciduous with leaf fall in autumn.
