Ephemeral Woods


The first wave of ephemeral flowers is waning, including the last of the Bloodroot, above, now replaced by a single, giant leaf for capturing the diminished sunlight of the greening woods.



Now, Wood Anemone, Anemone quinquefolia, can be seen in clusters, although not always in flower.



Here, a pink-hued Wood Anemone flower next to the inflorescence of Pennsylvania Sedge.



 And here, in white.



I am most excited to find large patches of Cutleaf Toothwort, Cardamine concatenata, on the northeast facing slopes, under the dying oaks and growing sugar maples.




I've become critically aware of the value of dying trees and fallen timber to the continuity of all life within the woods.



A tree growing for over a century dies (I've counted rings). The loss of leaves allows sunlight and additional moisture.



Maybe the tree is blown down in a violent summer storm or felled by constant gusts behind a strong winter cold front. As it falls, its massive, dense wood contorts and dismembers younger trees on its way down, creating an even bigger hole in the canopy.

Seeds that have moved via wind, runoff, or even more so by insects and small animals may be well placed, lying in wait for this opportunity to sprout. But you didn't notice because all that concerned you was the giant that came crashing down. A couple of years or more later, the presence of the fallen giant less prominent, there in the clearing is something new.

Findings


I'd like to tell you what kind of Oak this impressive bark belongs to, but in age, among oaks, it is a challenge without leaves. No matter, this old, large oak is anchored near a clearing made by wind of storms and pressure of fungus and disease.



On the bark of a giant that had fallen last summer, I place garlic mustard just pulled. I keep it off the soil so that it properly desiccates, a lesson learned a year ago. Now committed to the project of eradicating the weed, I think of it as gardening, a task with its own time, that I can accomplish while out photographing the woods, searching for mushrooms or ramps, or completing some other woodland project. Away from fallen logs or large stones, I make piles so the mustard remains obvious to me later, as I check on its desiccation or dispose of it. Officially known as Garlic Mustard, Alliaria petiolata, I've pulled enough acreage of it now to refer to it as "skunk mustard," because its garlic-onion odor reminds me more of that mammal's funk. Click here for a concise and useful journal article on all things problematic with garlic mustard in North America.



This upland spot was (still is?) an oak and sedge stronghold for quite some time. Now cleared of its main shade oak, what may grow in these changed conditions? Its slopes are partially covered with Pennsylvania Sedge, Carex pensylvanica, and some Virginia Waterleaf, Hydrophyllum virginianum. I found these native strawberries, Fragaria virginiana growing in patches, too. A straight line trail runs through this location, with plenty of soil disturbance from quadrupedal hooves and nosing through leaves and soil for food. Maybe I could intervene beyond pulling weeds by giving some complementary plant a foothold. We tend to avoid plants consumed by deer and in this way we consume them by exclusion.



While pulling skunk mustard I stumbled upon this snake, a common Eastern GarterThamnophis sirtalis. Its reaction to my sudden presence was no reaction at all.



As I continued to hover, pushing my fingers into the dried leaves to pinch-grab below the prostrate brassica stems, concern took over. I let it be, moving on around a tree to grab more mustard.



Then I spotted two more, one with coloration slightly dull compared to the other, sunning themselves near their burrow. My leaf rustling was too much antagonism and the one to the right took off. Minnesota isn't known for its snakes, although I am happy to see them here in our woods. Along with our frogs and salamanders, they are an important indicator of the land's well-being.



It's been very dry so far this spring (and despite constant snow cover, the winter was short on snow). In our new climate reality, we anticipate extended dry periods along with excessive rains from thunderstorms. Because of the lack of runoff from non existant spring rains, I was able to navigate the entire small wetland, plodding across acres of dried, sun-bleached naples yellow grasses. I witnessed the garlic mustard making inroads into the wetland as well as an arm or two of Creeping Charlie, Glechoma hederacea. I also spotted considerable patches of Stinging Nettle, Urtica dioica growing among the garlic mustard, but also several feet farther into the wetland. There is a tree, likely an ash, rooted at the edge of the wetland but fallen into it that has continued to send up branches along its trunk. Under the tree's crown there is a muddy circle where only the plants, above, are growing. At first glance I thought "Marsh Marigold?" Maybe not. Thoughts?

I did make a soggy-footed attempt into the great wetland on the south side. I wanted to see the willows -the first pale greening of spring, up close, but I didn't make it far enough in to be truly rewarded. Underneath those grasses were channels and ponds of water still draining from a much larger supply of slopes than the little wetland to the north. I did see evidence of Swamp Milkweed, Asclepias incarnata, about twenty five feet from the wood's edge. The exploration of the wetlands, our sunny places, compels me to engineer a boardwalk (literally -cut logs, debarked and placed longitudinally, with boards run lengthwise between them). Future projects.



Closer to the house, on the dry slopes bloom Bloodroot, Sanguinaria canadensis. Maybe these can be planted in the clearing among the wild strawberries?



There have been many sightings of hawks, vultures, eagles, sandhill cranes, turkeys of course, and others to make seeing the more common birds seem, well, common. Yet the first robin of spring was worth pausing for, as well as bluejays and cardinals hanging together.



And while squirrels aren't on anyone's favorites list, they have yet to cause us any trouble, likely because their habitat is still largely intact. They do not come toward the house and didn't mess with last year's garden. This bounding fellow has a red head, feet, and tail. I wonder if it this one, from last fall, or a relative.

Spring Chorus



You cannot see them, but they are there, near any body of water. They know when you are there, even though they are concealed under leaf litter, and will hush on your approach. If you wait, silently, they will begin playing their combs once again. They are the Chorus Frogs of March. See here for the group experience.
