Another protected area shielding two unusual trees is the three-sided enclosure of Ryan building. After pressing through the lower shrubs, you will see two large trees: Red mulberry (Morus rubra) (Fig. 11-1), native and common further South of the Lakehead region, it seems to thrive in this protected spot. It is deluged by birds, when producing sweet edible fruit (caution so you don't get "purple bombed"!).
Also present at this site is introduced mature gingko tree (Gingko biloba Fig. 11-2), with its characteristic two-lobed leaves which turn brilliant yellow in Autumn. This dioecious species is probably a male, since it isn't producing messy seed crop in the Fall. A young tree has also been planted near the administrative offices in the Centennial building courtyard (Stop 4).
Also present are a few shrubs, likely self-seeded, of red elderberry (Sambucus americana, Fig. 11-3 also a and b).
