Summer Scenes: Dry and Wet



Summer Scenes: Dry and Wet
June 13 and 17, 2016


June 13


June 17

Two different scenes greeted me as I went down to Cottonwood Pond on both June 13 and June 17.

On the 13th there had been no rain for a long time. But, then we had heavy rain through June 14 and 15, finally refreshing everything. June 17 was warm and sunny with no rain that day or the day before, allowing the previous rush of water to recede some. But, what effect did it have?

The difference between the slope and bottom land was becoming more distinct as spring plants died down (including the mass of Mayapple “umbrellas”) and the bottom land became richer with taller, leafier summer plants, and a greater density of them.

Of course, water flow was very different between the 13th and 17th. On the 13th, I could walk across the Isthmus, and some of the main and “little pond”, without wearing boots.

June 13

Temporary Creek #1 (which feeds water from slope run-off to the pond area) was fairly dry, with no new water refreshing it …

...and the Seep was not even visible, partly due to increased plant density.

June 13 - Pester somewhere near the invisible Seep

Even the Inlet was very dry.

But, after enough rain Temporary Creek #1 was quite muddy, with some puddles …

June 17

...and the Seep was becoming a little more active.

There had been water flowing through the Inlet again, into the pond, and the area required boots this time.

As I went to the pond on both days, I heard songs of Wood Thrushes, Peewees and others, and the sounds of Woodpeckers. Crickets sang. Black-Winged Damselflies, the males with deep black wings and jewel-like, iridescent turquoise abdomens, had appeared in increasing numbers between June 13 and 17.

June 17 - Wild Yam leaf showing flat gall spots left by a type of gall midge - the larvae has already dropped to the ground to pupate and the remaining spots are wearing away.


With plenty of mud on both days, there were old and new Crawdad chimneys, especially many new, small ones after the rain ...

… as well as Raccoon prints in the mud.

Another print that appeared, freshly, on both days, was that of a canine.

I hadn't seen any stray dogs around, and Kojak had not gotten away from his home. My guess was a Coyote, but I wasn't sure. I thought they were larger than Fox prints, though. Maybe I need to set up a night camera at Cottonwood Pond. That would make for some interesting blog postings in the future!

What of the pond itself?

Well, on June 13 there was no sign of water, other than some indistinct puddling in the deeper parts, but on June 17 the bowl was refreshed with a good amount of water, though not full.

After the dry period, I wondered what had happened to all of those frogs and tadpoles. Did the large loss of water cause a number of tadpoles to die from lack of moisture and oxygen? Had both frogs and tadpoles become more susceptible to predators, unable to dodge deep into water or pond bottom mud? I did see one frog stick its head out of a leafy puddle in the middle, then withdraw into invisibility just as quickly.

After the rains, I still saw no signs of tadpoles or frogs (without scooping up a water or mud sample), but I did hear some frogs jumping as I approached.

There was other activity in the pond on the 17th. Two flying insects, possibly some type of fly, flitted together across the surface, chasing. There was at least one Water Strider on the surface, and lots of spider strands stretched across the pond. A Willow leaf floated on the water, as well as some fluff from Cottonwood trees, which had been releasing their fluffy seeds into the air.

June 17

The Elderberry shrubs were thriving and increasing on the southeast side of Cottonwood Pond, mostly in bloom on the 13th, but showing some green berries as time went on.

Monkey Flower plants were growing denser and taller in the Swampy Spot at the near end of Temporary Creek #1.

Virginia Creeper vines were stretching across the bed of Temporary Creek #1 and also down either side of the Root Ball.

Honewort displayed its tiny, delicate white blossoms.

When I looked up the back slope on June 17, toward the fallen Cottonwood Trunk, I saw a distinct change.

June 17


During a previous storm, a Black Cherry tree had fallen onto the Cottonwood Trunk and was broken.

It was a very fresh break.

Would this fallen Cherry tree have an effect on the dynamics of that space?

Near and far views, on June 17, where the far end of the fallen Cottonwood had wedged into the notch of a double-trunk Red Oak on the back slope above Cottonwood Pond:




Walking along the Trunk, I noticed that the Wood Ear fungi had been renewed by the rains …

… accompanied by Raccoon scat left neatly on a high part of the Trunk.

Would we get some more rain, and would the pond fill up some more? How will things change as summer progresses?
