Lakeside
As we walk toward the lake, you'll notice the gray
squirrels, which seem to be everywhere in all seasons!
They don't hibernate in the winter; rather, they sleep on the
coldest days but are otherwise active, digging up acorns and
seeds that they've collected in the fall. Their population
size fluctuates dramatically in proportion to the acorn supply,
though Wellesley never seems to be short on them.
Here we are by the lake; this shoreline is one of the most natural
habitats on campus, and the plants we'll see here are mostly
native species which grow here naturally. See these dried spikes
of flowers on these shrubs lining the lake? They are last fall's coast
pepperbush blossoms, and will remain on the plant until next
summer. The pepperbush is one of a small number of plants that
flowers in autumn, and its sweet scent attracts huge numbers
of bees. Other plants by the lake include the highbush
blueberry, of whose delicious fruit you are most probably
aware.
Though Lake Waban is covered with ice at this time of year,
there is still an abundance of animal life in and around the
lake. Look for muskrats swimming
in open water. They build conical dens above the water, with
underwater entrances and breathing holes cut in the ice in the
winter. Song sparrows and
juncoes also remain for the winter, along with some Canada
geese. Several species live under the snow as well - look
at this mouse track!
Let's head back to the path now, and learn more about the sugar
maple.
