This past December, I had reported finding Fanwort (Cabomba caroliniana)
at the Frog Pond in the Dingle Park, Halifax.
Over the summer, I noticed it growing around most of the edge of the pond,
but it was hard to see how far it was growing towards the center.

Now, its small white flowers are emerging above the water surface,
making it easy to see the extent. In my estimate, 1/4 to 1/3 of the
surface is covered by Fanwort, generally in the shallow or protected areas.
As far as I recall, some of those areas were occupied by Water Lilies
in previous years. Water Lilies are a food source of beavers, which
have been on the pond in the past. Not this year, however. Maybe chance,
maybe they don't like to swim in a tangle of Fanwort (I would not want to),
or some other reason.

I had also speculated about Fanwort in Whimsical Lake, which is
upstream from Frog Pond. However, a few weeks ago, I did not see
any, but was pleased to find some bladderwort (Utricularia sp.).
