Climate change Gardening Nature ruminations

Relating to natural life today

In the last month I took a family vacation to the Great Smoky Mountains and read two novels about logging: Ron Rash’s Serena and Annie Proulx’s massive Barkskins. Here are some resulting thoughts about trees, creatures, and the people who inhabit their world.

The natural world in America is nothing like what it was

We fall into the trap of thinking that climate change is unprecedented in its destruction of the natural world. But it has a clear predecessor in the deforestation of the period c. 1600-1960, documented in Barkskins, during which nearly every tree in America was cut down, every forest razed, and most wildlife extirpated. The first two sections of Barkskins start with Europeans trapping all of the beavers, minks, and martens in the northeast. Only after the furs are gone do they move onto logging.

In Serena, the logging barons clear-cut the Smokies before selling the land to the government for a national park. Serena is fiction, but this part of the story is true. In the Smokies, we hiked to Avent Cabin, a structure built around 1850. It contains a picture showing its setting around 1920, when it sat in a clearing: all of the surrounding trees had been logged. Now the cabin is again back in the woods, as the regrown trees approach a century of age.

Of course, letting the land go wild again does not recreate the complex webs of life that existed before Europeans arrived. Keystone species like the American chestnut and the passenger pigeon are extinct and megafauna like moose and bear – characters in both novels – have limited presences. The city nature areas and state parks I visit are a sad joke compared to what they held five hundred years ago. At the end of Barkskins, a character muses about “dark diversity,” the species whose absences from an ecosystem can be measured. There’s a lot of that here.

Both novels do a good job painting the picture of natural splendor that was destroyed forever. As a Michigan resident, I particularly appreciated the Breitsprechers’ trip to survey the endless, towering white pines of this state. My family has stopped at Hartwick Pines State Park on our way up north, a tiny postage stamp of old-growth forest that escaped logging. It’s the closest we can get to experiencing what was once here.

Despite being once despoiled, the trees and wildlife in the Smokies were still beautiful by modern standards. This lifted my spirits. There’s something encouraging about the fact that we’re a hundred years past the low point for trees in the Smokies and moving in the right direction. When it comes to logging, at least.

Maples and Michigan’s February 2023 Ice Storm

Like most people in Ann Arbor, I awoke last Thursday to a chilly, quiet home. The ice storm had knocked out power. I took a walk around the neighborhood after the ice had finished accumulating and before it melted.

Maples are a small share of trees in my neighborhood but they made up the majority of trees I saw that had suffered major storm damage. Winter tree identification is a challenge for a novice like me, but I can often spot the common species of the maple family (Acer ) from their shape and bark. And because of the mild winter we’ve had, Ann Arbor’s maples were already sporting distinctive buds. I wasn’t able to pin down the species of maples I saw, but I remembered some individual specimens from their summer leaves. These were mostly Norway maples and silver maples.

Here’s a picture I took of ice-encased buds on a branch that had crashed to the ground:

What species is this?

Norway maples are an invasive species in Michigan and are now reviled across North America. Unfortunately, they were planted for years in cities, including in Ann Arbor. Silver maples are native to Michigan. Both species are known for being fast-growing, weak trees that are especially prone to storm damage.

On Sunday I was out on foot and bike and snapped a couple of pictures of maple trees that had failed:

On Hoover near Division
At Franklin & Seventh

(Please comment if you recognize specific species – I hope I didn’t get overconfident with my winter tree ID!)

The streets near my home are lined with mature oaks and I was struck by how little damage they suffered. One neighbor in particular has a dozen towering oaks and hardly had to clean up a branch. It got me wondering, what share of the electricity outages were attributable to the planting of maples near the power lines? If planting hardier trees would have avoided even a small fraction of outages, that might translate into fewer days without heat and refrigeration for many.

I am no expert here, just speculating from what I notice on the streets. I’d be curious to hear from urban foresters, arborists, and lineworkers who cleaned up the tree damage. I wonder, though, if we could build a little resilience against future outages by replacing and eliminating Norway maples and ensuring that silver maples are planted far from vital infrastructure.

In the meantime, my understanding is that the sap of the Norway maple has enough sugar to render it into syrup. And I’ve made syrup myself from silver maples. I have all of the equipment needed for syrup-making, but no maple tree to tap, and it’s unlikely I’ll get to it this spring. Let me know if you want to borrow my setup. And plant strong tree species.

DIY How-to Making Nature

Making a coat rack from a buckthorn log

This project hit many of my interests:

  • Eliminating buckthorn, a nasty invasive species
  • Reuse / making things from leftovers
  • Amateur woodworking
  • Contributing to Workantile, the co-working community I’m a part of

It turned out nicely. Here’s a writeup and some photos.

The rack

It started when I was biking home with groceries from Meijer and encountered a big pile of buckthorn by the side of the road, culled from Greenview Nature Area and awaiting pickup for composting. The biggest trunk was a decent sized log. The bike was already heavily laden but fortunately, a log is a different shape than grocery bags so I found a spot for it:

This was surprisingly easy to haul

For a while I’d been interested in woodworking with found wood, especially buckthorn. I take pleasure in removing it and would enjoy that even more if I could turn it into things. I asked my friend and de facto woodworking coach Chris how I should go about processing logs. Buy a bandsaw? Build one of those circular-saw-converted-to-chainsaw DIY mills I saw on YouTube? Both seemed excessive.

Sharing and Starting Plants

Today is Earth Day. It may be co-opted by brands posting on social media, but I think it’s still worth celebrating in its original spirit (see Emily Atkin on what Earth Day is supposed to be). I was considering posting about divesting from for-profit banks as a not-obvious but critically-important way to help the planet. I hope to do that, still. But here we are and I haven’t written it, so instead I’ll briefly report and muse about swapping seeds.

Yesterday I hosted an informal seed and seedling swap. It was just three of us, standing around a table in the cold, but it was a blast. One person brought chard seedlings, plus all kinds of seed packets including white corn and tiny cantaloupes. Another shared tomato seeds and seedlings of a family heirloom cultivar that his father has saved and replanted over many years.

After the swap, with plant life on my mind, I dug around in a five-gallon bucket of dirt. It’s a special bucket of dirt: my two-year-old and I filled it in the fall, then gathered acorns and mixed them into the soil. Our experiment was to see if they’d sprout after overwintering outside. And at least one of them has!

It’s rupturing with life! I moved it to its own pot.

Sharing seeds and plants and stories and tips and excitement on a cold spring day left each of us energized about plants and the earth. It renewed my sense of possibility, about plants and how humans are made to help each other. I plan to keep casually swapping seeds this spring and summer and then maybe run this swap again next year, with more planning and advertising to make it bigger. I hope to start seeds indoors next winter to contribute seedlings of my own.

In the meantime, I have a ton of pawpaw seeds on hand that need new homes. I processed dozens of fruits in the fall, setting aside the seeds. They’ve been kept moist and in the fridge all winter to give them their requisite cold hours and now should be ready to sprout when the soil warms up.

Pawpaws are unusual fruit trees, native to Michigan (among other places). The New York Times wrote a couple of stories about them last year. Their seeds are slow to sprout and not the easiest to grow, but I’m taking it on as a challenge.

I also harvested a lot of Red Russian kale seed from my crop last year. I have maybe a thousand seeds left after planting and giving away lots already:

My half-full jar of remaining kale seeds. Think it’s thousand? More? Less?

If you want some pawpaw or kale seed, or want to trade other perennials like sunchoke tubers or prairie dock seeds, drop me a line.

Let’s swap seeds and stories next spring. Happy planting!

Welcome, Brood X Cicadas

Next month, if all goes well, Ann Arbor will be overrun by millions of Magicicada septendecim, the seventeen-year cicada. I am giddy with anticipation.

Why am I so excited? I think the cicadas are arriving at just the right moment in my life, in terms of both time and biophilia.

The timing is fortunate. At 3, 6, and 10 years old, my kids will be old enough to appreciate the insects and still young enough to feel wonder. My oldest is already on board: she amassed a collection of cicada shells from more regular “annual” cicadas that emerged in recent years. The next time these cicadas emerge, my kids will be grown, and I may be an empty nester. My oldest will be the age I was when she was born.

I’ve experienced periodical cicadas twice so far, in both cases Brood XIII in Chicago. I was 6 in 1990 and vaguely remember the insects’ ubiquitous noise and bodies. When that brood resurfaced in 2007, I was 23, and have no memories of cicadas from that year. I lived in a 24th-floor apartment in downtown Chicago – maybe there was too much concrete to support any cicadas. I remember my friend Boyu, who was working in the western Chicago suburbs over the summer, telling stories of brushing his car off before getting in and still ending up with cicadas inside. But for the timing to work, I think that would have been stragglers emerging off-year in 2003, which I would have missed in the city.

Now the reverse is true: I’m in the right part of the state for this year’s Brood X emergence. Much of Michigan will miss the cicadas, but Ann Arbor should be as reliable a place as any to experience them.

This will be my third visit with periodical cicadas. Brood X will next emerge in 2038 (I’ll be 54), 2055 (71), and 2072 (88, if I last that long). After this summer, half of my cicada seasons will be behind me.

The cicadas are also coming at the right time for me to appreciate them. In the last year or two I’ve become more appreciative of, knowledgeable of, in love with the natural world. I’m learning about animals, trees, and as much of life on this wondrous planet as I can, cultivating my biophilia. It blew my mind to learn about oak trees evolving to have mast years, where in some years they sync up and together produce an unusually-large crop of acorns to overwhelm predators. Periodical cicadas have evolved a similar mechanism of using staggered timing to their advantage: when they emerge in such great numbers, predators can’t eat them all.

What an incredible feat of evolution, to lie in wait for seventeen years and emerge in concert! I find that outcome especially neat given that at this point, they only reproduce as often as humans do. When the parents of this year’s Brood X cicadas walked the earth, George W. Bush was still president. They wait so long for just a short couple of months above ground. It reminds me of tree time or rock time, timescales slower than our human experience. This strategy has been slowly optimized over millions of years. What to me is a rare, long-awaited, blog-worthy event is just the next repetition of their experiment.

I feel lucky to be living in the right place and right moment for this event. It’s a six-in-a-lifetime occurrence and I don’t even have to leave my neighborhood to enjoy it. This weekend, I’ll pick up a book on cicadas from the library to prepare myself, and look forward to May and June. May this brood be as thick and deafening as ever.
