Water Life
March 28 an 29, 2017
Water, water, water …
is what normally makes up Springtime, an a big part of bringing
everything to life. Things were sure springing to life at Cottonwood
Pond by late March, especially in the water.
From above the area, I
could get an overall, clear picture of how the area had been
changing. One very distinguishing aspect was the obvious heavier flow
of water from the Swampy Spot to Cottonwood Pond. In the above photo,
to the right of Cottonwood Pond, you can see two dark trails carved
through the light brown leaf layer, from the right (Swampy Spot) to
the left. The upper trail heads toward the Trunk, going under it to
“little pond.” The lower one heads down from the Swampy Spot and
then curves left until it goes through the Inlet to the main pond.
Here is a closer view:

You can see the very
watery Swampy Spot n the right, then the upper and lower flow trails
to Cottonwood Pond. There seems to be more greenery developing along
these flows.
When the Swampy Spot first
developed there were not discernible flow trails from it, except
during periods of excessive rains. But, in spring of 2017 I had been
struck by how deep and obvious the flow trails had become. And, so, I
speculated:
- I predicted that Temporary Creek #1 (which runs into the Swampy Spot) would become a true Creek, running ever more heavily into the Swampy Spot, which would expand and deepen. The Swampy Spot might become a good study spot itself!
- I predicted that those two flow trails from the Swampy Spot would become much more prominent and dependable, to be deeper, more regular sources of water for Cottonwood Pond.
- I predicted that distribution of plant life would change along those flow trails in type and number, and so would animal life.
- This, along with the stronger flow, would create significant changes in the amount and diversity of life in Cottonwood Pond.

And, that was going to be
very much fun to observe, study and document.
March 29 - Fresh
Crawdad chimney next to the Swampy Spot
On March 29, I took a
closer look at Cottonwood Pond, focusing mainly on life in the water. I took water, mud and submerged
leaf samples to bring indoors and study more closely under scopes later. I have always wondered how to categorize this place. Since one possible
option was “vernal pool,” I was looking for any species that
would define it as such, a main one being Fairy Shrimp.
Heading down the front
slope, I encountered bunches and swathes of blooming spring
ephemerals, an elegant mushroom, and a prettily colored Garter
Snake.
Water in the main pond was
fairly clear, as the fine sediment had settled onto the leafy layer
below. The increasingly large Mud Piles were nestled against the
Cottonwood's Root Ball Bottom. They had become greener as some plants
had grown larger and more had sprouted.
Notice the clumps of moss on the Very Rotten Log (lower right), full of sporophytes
I noticed a new
development on the larges Mud Pile (formerly Mud Pile #1) – two
tall, fresh Crawdad chimneys made of pebbly blobs of Mud Pile mud.
I had not seen Crawdad
chimneys on top of the Mud Piles before.
From the long view, I
could see where the tunnels ended at the base of the Mud Pile, just
above the water, providing easier access to potential Crawdad
dinners.
This also looked to me,
though, as if this location would make the Crawdads more easily
accessible as dinner for Raccoons.
Those blobs of green algae
I had recently seen in the water seemed to have grown, an I thought
it looked like there were more of them. I took some samples for the
scopes.
Wriggling around in the
water above the algae blooms were some mosquito larvae.
Above spots of
unobstructed leaf layer I was able to clearly see many more, hanging
downward from the surface from where they were siphoning oxygen
through breathing tubes.
Below water, brushes on
their mouths were filtering in anything minute enough for the larvae
to eat. Frequently, a body would curl up and release in a wiggly
dance back to the surface. Very soon, surviving larvae would become
pupae or “tumblers,” on their way to winged adulthood. The larvae
are food for many other organisms, but we always hope that not too
many of them make it to adulthood.
I was hoping to find some
frog egg masses in the water, since I had been hearing so many Chorus
Frogs calling. I did find two gelatinous masses attached to a twig in
the shallow. It was possible they were full of frog eggs, but even my
loupe magnifier did not convince me.
A closer look revealed a
few white blobs. What were these?
Another mystery at
Cottonwood Pond. I hoped to find these masses again the next time I
could check for them, and that their identities would be revealed. I
also had always hoped to find salamander eggs in Cottonwood Pond,
though I had not yet encountered a salamander there.
Some leaves on the pond
bottom had distinct trails through the sediment that almost resembled
the tangle of the canopy above the area.
What made these?
Notice the white blob on the end of the leaf petiole (lower right), sticking out of the water - it may be some type of egg mass.
A closer look revealed
what I had suspected – pond snails scraping algae and decayed material from the leaf surface.
I did not get to see any
of the elusive Chorus Frogs. But, this critter showed up, as still
as a statue, always with an eye on me:
Green Frog
When I shared this closeup
photo on Facebook, a friend noted that the frog's eye was reflecting
the woodland behind me. I think that a good title for a children's
book might by “The World in a Frog's Eye.”
Look at the little bubble
near its mouth (okay, Frog, we now know you are not an inanimate object - you are breathing!) Below the frog is a pond snail on a leaf.
Near the frog's
left toes there seems to be a worm-like creature on the leaf. Now, a
snail has moved to a leaf petiole on the far left.
Things were really picking
up at Cottonwood Pond, and I hoped that I would discover more
exciting finds in my samples under the scopes.
In the meantime, I would
be keeping an eye on everything, and I knew that wildlife would be
keeping an eye on me, too.

ReplyDeleteI think you should write that children's book.
