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.

Adaptation

The Wekiva (Weh-kee-vah or wah) Spring Run flows onto the Wekiva River which descends from the Florida central highlands into the middle sub-basin of Florida's longest river -the St. Johns. To the canoe or kayak paddler the riverside can appear strange with its palms, bromeliads, and trees bearded by epiphytic Spanish Moss as much as boats captained by duck dynasty types.

Among these, however, are familiar plants and animals of the north -water birds, trees and forbs like red maple Acer rubrum, pickerelweed Pontederia cordata, heron, egret, and white ibis (above).

The red maple, its trunk visible on the far left of this photo, is likely one of the most adaptable tree species in North American native silviculture. I am familiar with it from road travel throughout New England and the Mid-Atlantic where it can often be seen in lakeside swamps turning red before autumn gains a foothold. Cultivated forms are also common to streets and yards. Although I have not seen it among our wetland edges or woodland swamps, it certainly grows here and farther north in Minnesota. It is both water tolerant and drought tolerant, shade tolerant and sun tolerant and quite obviously, heat and cold tolerant. A red maple grown in the south may not do well in the north as well as the reverse, but the tree exhibits great genetic variability and adaptability.

Given that our once vernal swamp has become, for the last three years at least, a year-round swamp due to frequent heavy rainfall events, geomorphic characteristics and a rising water table, nearly all of the vegetation has died. The last of the very large trees, namely green ash Fraxinus pennsylvanica and basswood Tilia americana, that tolerate a few months of standing water every year, have finally succumbed to three years of permanent inundation.

The adaptability of a tree like red maple struck me as a good fit for such a situation -able to tolerate the standing water or, should things change, do fine in simply wet soil or even withstand a drought. Research shows that the native tree has increased its population since the time Europeans arrived to the continent, and in some cases may be viewed as an opportunistic, invasive species. This is something I will need to weigh against the other invasive, exotic species that have taken advantage of the sunlight provided by the sudden death of the slough's canopy.

A struggle I've had over the last two years since I have moved to our place in the Minnesota woods is how to preserve and restore the woodlands and wetlands around us. It is disheartening to see government maps describe parts of our woods and wetlands as of "moderate" quality or "altered non-native plant community: no native species present" which are both misleading descriptors. However, after two years' time I believe I understand the extent to which this place has been altered by human interaction and all the species that have followed it.

In acceptance of these changes, why not be proactive? Why not plant species that can take advantage of the new conditions? Why not plant pickerelweed and red maple in the flooded slew even if they are not currently growing on site? The wish to return such a drastically altered site to a pre-human condition is not only foolish, but nearly impossible. What I am likely to consider, now, is gardening the woods and swamp with native plants, without the restrictive edicts of restoration.

Lizard's tail Saururus cernuus was identified on one Florida boardwalk trail. Is it beyond its cold tolerance in our slough? We are likely on the edge of its range, but I'm game for a try.

Any time spent in Florida with plants leads you to think about "houseplants," those typically subtropical and tropical plants we attempt to grow indoors. Seemannia sylvatica, above, may be hard to find locally, but it promises to be a great winter friend in a west facing window.

In a surprise turn, our limited collection of easy care houseplants has increased dramatically despite the winter's desiccating indoor humidity level. Beyond the easy pothos, sprengeri fern, and oxalis we are now overwintering a substantially larger rosemary shrub (2nd year), lavender, two opuntia spp (2nd year), two agave spp (2nd year), a rather large pineapple sage Salvia elegans (which blooms so late here that this may be only way to get it to flower before frost), dusty miller Senecio cineraria (last year it overwintered outside), and the odd petunia.

Now, for the peculiar case of the petunia. At some time, maybe it was August, I noticed a petunia flower underneath our terribly diseased tomato plants (a terrible year for them). We had no petunias at the house this year or last and certainly had none in the vegetable garden. I gave a pass to the notion that it self-seeded from petunias that may have been located in the long window box along the garage in years before our arrival. After all, I find tomato plants sprouting all over the gardens despite occasional -15 or -20 F nights over winter. After a few weeks I decided to dig it up and move it to a more visible location in the raised herb bed, near the parsley, where it continued to flower until the first frost sometime in November. There it lay for another couple of weeks, its pink blooms preserved by the cold. When the first deep freeze was about to set upon us we cut back the herbs for use in the kitchen but left some of the parsley under cover to keep fresh for another few days. On that last day of natural viability, when all over-wintering plants were required to come in, I realized that the petunia was still green, pliable, quite alive. I dug it up, potted it, and it is now doing well on our window sill with a mass of new leaves.

Winter Mind

Winter has finally come to us. Temperatures below 20 degrees F, snowfall, car doors frozen shut with the last freezing rain, the clinkeling of ice crystals shed at forty five miles per hour. Despite this wintry attitude, we here at PrairieWood have work to do. The new shop is now standing with roof and ceiling. It never occurred to me that I would work into the night, outdoors, at just a handful of degrees above zero, but I did just that last Sunday so that we could get the wiring in before the ceiling closed out our access.

While I've been able to put most house projects on hold until springtime, one thing is still weighing heavily on my mind -the woods. What once went concealed by countless leaves is now made obvious by the contrasting wet bark and newly fallen snow. If I could sum up its appearance in one word, it would be diagonal. What is it about a wood of slanted trees that is so disturbing? Is our sense of order satisfied by horizontal ground and vertical columns of trees? Is the removal of angled wood a goal of a "clean" woods? 

What we need here is a plan, a forest plan, to guide us in the care of these woods. But wait. Why do the woods need our care at all? Isn't that awfully anthropocentric? Couldn't the woods take care of itself as it has for thousands of years?

Why is it so hard to look at the woods and see ourselves in it? We entertain the woods as a medium of passage. We experience the woods, but are not a part of it. Our aim is to be out-of-the-woods. We are beasts of clearings where a few selected trees may stand sentry. Why not the woods? Is it a blow to our ego to be among such large beings? Or is it the inherent danger of a sustained presence in the woods, the mashup of life and limb? Maybe this is the most practical tack, that a life in the woods is a life fraught with falling timber. Even among the trees there is danger. No elderly tree gives way without taking or scarring those around it. The falling of a great old tree reverberates through the forest, destroying the order, remaking communities, providing opportunities for well placed upstarts. 

I've realized how easy it is to make a metaphor of the woods, but the questions are more difficult. In our short time here we've had to ask many, and no answer is quite right. Any intervention is yet another question, or string of questions. We cannot extract ourselves from the story of the woods; people created it and we are living it. 

I regret to speak so abstractly, but somewhere in this line of thinking is a better perspective that may be teased out in writing. I understand intuitively that we have a role in this mess, that we are the aliens among the trees, roadsides, and fields. We cast dispersions on the plants and animals that take advantage of sensitive niches, but were it not for us this would hardly be the case. We are the aliens, the agents of drastic change. We project it onto others (plants, animals) while claiming our place. There would be no buckthorn, no garlic mustard, no barberry or burning bush if it weren't for our own invasive nature. Can we make it right? Can you take it back? Can you undo the done? 

This is a defining aspect of our culture. We invade a place, instigating the consequences that we see all around us and then tell ourselves that it is the others' fault, it is their doing that has created the mess and maybe, just maybe, we'll commit resources to cleaning it up, and it will be ongoing, forever perhaps. The productive citizen looks away; it's just easier that way, isn't it? We can spend a life throwing resources at a problem that traces back to exactly where we stand. Is it rational to label plants and animals invasive and yet completely ignore our responsibility for it? 

In the woods I see the paradigm of our conflict, one as much with the natural world as it is with other human beings. I am left asking you if an answer, one that can never be fully right, is to look away or to commit the resources to try to correct the damage, forever, perhaps. And what to make of the trying, because trying isn't necessarily accomplishing anything other than assuaging one's conscience of total responsibility. 

I don't mean to be melodramatic. It's simply that so much of what appears to ail us today is hindered by our unwillingness to take responsibility, or at the very least, to understand our responsibility. I am not personally responsible for the rampant buckthorn in the woods, but I sure can see how it came to pass and how I've benefited from our ancestral migration to this place. 

Ignorance (in the sense of not knowing, but also ignoring) leads to bad decisions, or self-centered ones, and consequences difficult to ameliorate. For instance, water holds in the middle swale, in the back woods, and leads to ponding, mosquitoes, and to water-logged roots which can bring an untimely death to the trees there, fallen timber, more sunshine, and then faster buckthorn spread. I considered trenching a drainage so that the captured water could drain into the great wetland. Autumn came and I saw that some trees at the center of the middle swale remained green-leafed long after the rest went yellow.

Upon investigation, the bark and leaf, below, spoke. These are silver maple, Acer saccharinum, the fast growing, brittle-wooded tree of wet areas in the Eastern Forest.

I can only guess that silver maples living at the boundaries of its range put the species under pressures not necessarily found near its core. So I came to an understanding of this middle swale. I will not dig a trench to help drain it, yet I will dig deeper into what else is growing, and dying, in this area, and attempt to understand it before acting or, quite possibly, not acting at all.

The questions of how to act and what sustained gestures are both possible and effective, are for our winter mind. What can be done that limits the rampant buckthorn and doesn't undermine the fragile species under threat from its able fecundity? We spent a quantity of time pulling garlic mustard from the drainage stream connecting the northern, small wetland to the great, southern wetland. Our work was effective, but it also appeared to me that there was a significant reduction in jewelweed in the very same area. I'm working on memory, now, but I thought it was more prolific in that region in past years. So I wonder, was it the garlic mustard that reduced the jewelweed population to nearly zero, was it natural swings in population due to unusual temperatures or flooding, or was it our trampling feet that inhibited its seed from sprouting? 

Every action has consequences, so many of which are unknown. I recall how, as a child, certain people were inclined to spray pesticides into the tall oak trees to bring down gypsy moth caterpillars. Our camp director screamed, during lunch, that by God he was not going to allow those trees to die! Our neighbor brought in a pump truck, unannounced in summer time, and sprayed his trees. I am still haunted by the overwhelming bitter smell of the pesticide, the sticky residue dripping from the trees, the dead birds and squirrels on the ground. His trees didn't die, nor did the camp's, but then, neither did the vast majority of unsprayed trees.

Each of us who is responsible for a part of the woodlands at the edge of the prairie has to choose for ourselves whether to act, or look away, to spray herbicides and trample, or do nothing. There is no mandate, we operate independently of our neighbors and yet nature cares little for these arbitrary boundaries.

I am inclined to act, yet feel overwhelmed by the magnitude of what is necessary to be effective. We hesitate to spray herbicide, usually in two or more applications, but pulling is incredibly time consuming, physical and often, incomplete. Should we adjust to the new, simpler woods, make peace with the knowledge that we brought this thicket on ourselves? Could there be a middle ground where buckthorn and garlic mustard and all the others are accepted to a degree, where we do not look away but effectively manage the woods?

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.

New Label

I look outside the kitchen window to see this maple showing color.

Below the nook I see the hydrangea paniculata is turning too. 

Just a week ago the blush of pink was barely visible. "Autumn" is a new label here at MOUND.

What's Your Poison?

When we started clearing the woods of garlic mustard this May, it didn't take long before I began to spot small shrubs that looked like poison ivy, but may or may not have been. I have long been aware of the morphological nature of poison ivy, Toxicodendron radicans. In the blazing sunshine of New York beach dunes it shows as a glorious shining-leaf shrub thicket or in the dry woods of Long Island it appears as a vining, often shiny but not always, plant growing up trees or just as often a three-leafed low shrub colony at the edges of woods and fields. In the deep, wet woods of Maine it often took the appearance of fresh, pale greenery growing low to the ground. 

Rex always said poison ivy was not growing on the property, but I knew it grew across the road in the sunshine, in front of and under the Alders. Because my possible sightings took place in dappled sunlight or on slopes recently made sunny by fallen oaks along with what I consider a cohabitant, wild grapes, I began mentally bookmarking each specimen as a potential rash. I posted on FB and the results were nearly fifty fifty split between poison and not poison, yet no one could provide a possible alternative to poison ivy.

Leaves of three, let in be -so the saying goes.

But what of this? Sometimes PI looks just like trees.

Another clue is the short branches on side leaves, long on front leaf. 

Surely that is poison ivy. Alternate veining on the leaves.

You say, no way -not this one? But see here. 

Mitten-shaped leaves, leaves of three, alternate veining? 

Reddened stems, alternate veins, short side stems, three leaflets, perfect habitat?

If this isn't poison ivy, then what is it?

Turns out that's not poison ivy growing about our dappled clearings. This one clue deciphered it: opposite branching on our plants. Poison ivy has alternate branching. How did I figure it out?

While Betsy and I were clearing the area around the mailbox at the road, I saw a small tree, but definitely a tree, that had leaves just like our little specimens around the yard. I googled tree that looks like poison ivy (why didn't I think of that first?). It's an Ash Maple, Acer negundo, also known as Boxelder. After two weeks of surveying, each had grown enough to reveal their true identity. Then I found this definitive guide that goes beyond all the hooey about leaves of three you'll find on the Internet. Keep the pdf on your phone when your hiking and all your identification problems will be solved.
