March of Change


I haven't been into the woods much this winter, but for an occasional 30°+ chainsaw operation. Now, the growing day length, the day's work done, it was time to spread a bag of collected, mixed seed somewhere the sun may shine in the green season. 


The melt and evaporation is near constant, even on days well below freezing, but with this colder winter, refreshing snows were common. Now, with March's warm sun, the snow loses ground and the ground gains moisture. The thaw begins above, sinking into the earth, and its moisture mixed with mineral soil is a cold way to speak of mud. Mud is an element; we protect ourselves from it. In March, mud season begins in earnest, so a crisp mat of snow is a welcome traveling companion.


En route to the seeding region, snow delivered a graphic of animal traffic. The crossroads, the indecision, the quick and the casual are all written in the snow. I cannot fathom it, but isn't there a similar, but scented, pattern here only recognizable to those more dependent on the nose?


The wavy trail of, probably, a deer mouse on a journey of late winter courage as the red tail hawks and bald eagles glide high and the barred owls lurk mid canopy. 


By early March, ankle deep in snow, deer browse the dry, fibrous stems of the garlic mustard that they refuse to consider in the green season. Food of last resort, in winter, but never, not at all, when the buffet is so grand in May.


I did not understand how comfortable our mammal friends are with human paths before this place. I will take their cue as trails are altered by fallen timber, such as here. The trail used to pass to the right of this basswood, until it began to fall apart, completely blocking the old trail. The deer have made their decision; they now travel under the arch of a sibling basswood, the Arc de Ruminant.


In the late winter we take stock of the dead, the ill, the weak. The tops torn from hollowed basswood by time or wind, the snags of elder oak, rotted, but standing, the insect kill green ash and drowned every species in times of high water, are most evident in winter. Snags are important ecological components of the forest, whether killed by native or exotic means. For us, snags are question of safety, of food and shelter for wildlife, of timber taking out healthy neighbors. Few nearby young come out unscathed when elder trees fall and fall they do.


Of the remaining oak giants, red and bur of about a dozen on the drier, south facing slopes, we feel concern. These trees are one hundred forty, one hundred sixty, or more years old based on the rings of smaller felled oaks. They may outlast me, or not, but the point is not to count on a static nature, that is not what nature is.

As spring approaches I ready myself for the multitude of upcoming tasks and adventures. Many house and landscape projects remain, including seeding thousands of native woodland plants and harvesting two plots of Hudson Clove garlic, but also new opportunities. I have several upcoming photography courses at the Minnesota Landscape Arboretum that are filling up with those eager for something new from somebody new. I am also going to be working with scientists over the coming year, as artist in residence, at the highly regarded research landscape known as Cedar Creek Ecosystem Science Reserve. I plan to blog from Cedar Creek, nine square miles of otherwise inaccessible nature at the junction of the prairie, eastern deciduous and boreal forest. Stay tuned.

Woodland Orange


For three days I've been spotting an unusual orange deep into the middle slough woods, but it was early, rainy, and the mosquitos had finally blossomed. On the fourth day I traveled down the Alwin trail looking to take some photos and confirmed what I tried to dismiss -Laetiporous sulphureus.



Not only is this appearance unusually early, it is also in an unlikely location. The log has been down for years, is partially decomposed, covered in moss, and completely surrounded by water. Because I didn't act quickly, the mushroom received a couple of rain soakings, but it was completely bug free -a benefit of its island location?

Our two woodland sloughs have been steadily filling with more and more water, often independent of rainfall. It is an unusual occurrence that we feel may be connected to the partial filling of the gravel pit adjacent to the west side of the property. Rex was concerned that this change would raise the water table, and his concern appears to have been legitimate. In the back slough, nearly every tree has died -there is one old, large ash surviving the inundation. All the shrubs that were green in prior years are grey. The trail that was always accessible along the western edge is now completely submerged and invisible so that a new path will need to be cut much closer to the property line.

We do not want the trees in the middle slough to die off from inundation or fall in a storm because of soggy soil. The increased sunlight will advance an army of buckthorn well positioned on the south slope and already making headway in the middle slough. If it does not begin to drain we are likely to dig a drainage, or rather enhance the drainage that already exists. Any action of this magnitude will have consequences, but we cannot consider our woodlands as anything but altered or unalterable -it is a place completely transformed.

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.

Cedar Blush

The foggy morning was a prelude to the storm that just ended. Blue sky, something we've had little of this winter, is now in its stead. It is these weather events that make a cold climate tolerable, just rewards for what can be hard.



Moisture riding the push of warm advection crystallizes on cold twigs and grasses.



And sumac not yet pecked by the birds.



I love the cedars that grow here; reminding me of those that break the monotony of old fields on Long Island. They, of course, are the same species, and aren't truly cedars -Eastern Red Cedar, Juniperus virginiana. These are tough trees, can be over nine hundred years old, tolerate drought and wet, cold, and the poorest soils. While deer browse your expensive arborvitae hedges, by the looks of the Eastern Reds around here, they hardly touch them. There is gin, of course, and the aesthetics which, to my eye, are some of the best an evergreen can provide.

There is a moment every autumn, usually middle to late, when the cedars turn bronze, red, mauve, blushed or however you may see it. This change requires a loss of some of chlorophyll's green and the development of red anthocyanins and the two, together, create this bronzing effect. This is painter's stuff, mixing reds and greens to create blacks more green or more red. The dark bronze contrasts with the white of aspens and snow and plays well with ochre field plants.

Like so many plants you love, someone, somewhere lists them as invasive. How can this be, you ask, after all it is a native in its range! Well, I rationalize it this way -Eastern Reds grow readily in farm fields and get a bad rap for its ability to grow readily from bird-dropped seeds in these fields. The other reason is the loss of fire as a control agent, but this is our fault, and we shouldn't be blaming the cedar. Finally, because we plowed under so much prairie that there is less than one percent of it left, managers curse the Eastern Red for colonizing what's left that isn't being managed by fire. Given these rationalizations, I still wouldn't blink if I had the opportunity to plant one on our land.  I may well have that chance in one of the many clearings created by downed large oaks or bass that have given rise to another accomplished colonizer -common buckthorn.

Felling and Bucking



This, nine months ago, seemed a good spot for my garlic patch. It's gently sloping, south facing, and clean. Trees would need to come down. The garlic has been shipped, a bit late I think, no doubt due to the raging fires surrounding the garlic growing regions of Washington. One of my favorite suppliers had nothing to offer this season thanks to drought and fire.

What made this spot the obvious choice for my growing also made it the obvious choice for an outbuilding. At the Minnesota State Fair we spoke with a manufacturer of these buildings and they came out to the site. Last Friday, we signed. This January they start building.

My job is to make sure the site is cleared and excavated, plans and permits submitted, and the extra components -gravel, concrete, electrical and heating all get done in a coordinated fashion.

Whether it be garlic or a structure, felling trees is necessary. It's is not something we take lightly. Betsy's dad never cut a live tree, but he never had too. His old property was sculpted long ago and this new one is a work in progress.

A chainsaw wielding neighbor has done all the trees larger than four inches. Together we chip the branches and pitch the bucked logs into his truck. Dragging sixteen foot long leafy branches to the chipper, tangled as they are with other branches, over ankle twisting logs and stumps is rugged work and physically draining. Most I can do is three hours at a time.

Nothing shall be wasted. The black cherry and hickory limbs have been chipped for smoking meats. The firewood logs are partial payment to the chainsawing neighbor. We've saved several eight to twelve foot logs for lumber: hickory, black cherry, sugar maple, red oak, ironwood, and basswood. The Minneapolis College of Art and Design has a furniture program with a saw mill that goes relatively unused. We are affiliated with the school now and may take advantage of this idle tool. 


Basswood, Tilia americana, are weak-wooded trees that can grow to great heights. In other words, fairly dangerous for buildings and even people. I had one come down right in front of me last March, on a perfectly still day. I lucked out -the sound of trickling water distracted me from my path. Then, snap, and a sixty foot tree leaped from its trunk, landing just were I would have been had I not been the type to be distracted by burbling freshets. This one was, and two others will be, cut to prevent any interaction with our new building. With hesitation we are sparing a very tall cluster between the back yard and the new building because it provides some shade and screening between the house and the outbuilding. Are we sparing the monster?



The Vermeer. It eats wood for lunch.












I did all that I could to figure a way to spare this sexy red oak, Quercus rubra. These trees have strong wood, and stand for years after they have died. And they are dying, thanks to the oak wilt fungus, Ceratocystis fagacearum. Our woods is a chaos of wind fallen trees and branches, woodpeckers and other bark boring birds and insects. This damages the oaks (and other trees) and makes them susceptible to the insects that carry the fungus. The trees, once infected, die rapidly -usually a month or two, and it's dead by July. Felling trees must happen in the cool season or winter, branches chipped or burned. The logs need to be bucked and split for firewood. Drying them apparently puts an end to the fungus. Yet, we're not fooling ourselves -the red oaks are dying and we won't be able to stop it.



I didn't know there were small patches of hickory in our woods, but since identifying this one, I've found two clusters of more substantial trees. I haven't yet discerned whether these youngish trees are shagbark or bitternut, but I will let you know. The branches of this hickory have been chipped for smoking, a log saved for milling, and the rest went to firewood.



Sling the rope over the top.



And pull in the direction you hope it will fall.



Finally, there is limb work outsourced to an arborist with a cherry-picker. 



He will also tackle a couple of wilt-dead oaks from a few years back and this dangerous limb hanging from a very old sugar maple.


Later, maybe, we'll get to the several large oaks and basswood that have fallen throughout the woods in 2015. It appears to me that all the older trees are dying; a changing of the guard. What will these sunny clearing produce? Multitudinous sugar maples from the north, invasive buckthorn from the south, and whatever it is we have to say about it.
