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.

The Boy's Winter


I was wakened by the subtle flash and rumble that, not more than a minute later, became the brilliant glare and shattering crash of this year's first post midnight, pre dawn thunderstorm. The rains came, soaking what would normally be earth frozen forty inches, give or take. The birds had been arriving for over a week, vees of geese are seen and heard, while the prehistoric calls of sand hill cranes are heard, all traveling northerly. Comb-playing chorus frogs have made their seasonal debut and chipmunks have ascended from their dens. The grays and pale orange-reds predominating the woods are often punctuated by intense, moisture-activated greens. Most lakes have lost their ice and those that haven't remain only a stormy-green skim coat of icy slush. Most of all, even by last year's early spring standard, the trees have been budding strong and flowering early. The silver maples of the middle slough have been fully in flower for over a week. This is El Nino in the Midwestern north.

It should still be winter by calendar, averages, and tradition and this post should be timely. It is not, however, by fact and experience. Winter is over before its time and this is its eulogy.



Strong winds raked snow and desiccated grasses across the large wetland, leaving easy access for bipeds like myself.



This winter's fluctuating temperatures created a nearly constant stream of runoff from the little wetland which pooled at the northern end of the large wetland. It was a popular watering hole for all the Big Woods' animals.



Freezing and thawing of the pool made for unique ice crystals.



The dead trees of the large wetland, killed by higher water or blight.



Orange lichens on the south side of the trunks.



Wet feet is not a problem for Red Osier Dogwood, Cornus sericea.



Its branches a brilliant red in the sunny open of the wetland.



A protective structure for warm season nesting.



An unknown plant, possible weed, growing in the center of the wetland.
