The Return of the Vandal(s)

We are not alone, for better or for worse.

The Burlington Free Press on Sunday wrote an excellent article entitled “Taking it out on Trees: Vandals go out on a Limb“. In it, Joel Baird writes of the problems with vandals in Burlington, and a student in my old dorm at UVM who spoke up. He called me as well, after reading of our travails here at Middlebury on the blog. He writes-

“Parsons said he believes a strategy of engaging more students in their landscape likely will pay higher dividends than highlighting the acts of a few misguided vandals. “If you publicize it too much,” he said, “you risk getting more of it.”

I also enjoyed the comment section, where someone under the psuedonem Caberg posted a comment that got deleted (wished I’d read that one!) then re-posts and says

Huh? All I did was point out the ridiculousness of Tim Parsons’ personification of trees and the acts of “violence” against them: “This is an act of rage, of violence, well beyond wanton destruction of property, senseless passing violence against an animate object incapable of screaming or defending itself”

I’m all for punishing these vandals and I love trees and naute, but let’s not get carried away here. Trees are not people. Suggesting otherwise ust makes you look like a fool.

Heehee. Yeah, I’m a little foolish. I can live with that.

So I thought I was done, finished writing, whining, wailing, lamenting a priviliged student’s acts every weekend, stopping count at 10 weekends in a row. On to writing about happier things. Then Friday night, another branch on my favorite Katsura tree on campus.

And it begins anew.

Not exactly Gardening News

In the spirit of Tim Spear’s blog post “Not Exactly Administrative News: 10 great albums of 2010“, I thought I’d write about what’s been captivating me sonically for the last year.

Maybe a brief explanation would be in order first. I don’t listen to music much, mainly All Things Considered (and some of them even talked about) on the way back and forth from work. I do run, though, with an iPod Nano (read a great explanation of the system at the Middlebury Trailrunner), so to distract myself from the fact that I’m running I play loud obnoxious Alt-Rock. It’s probably a midlife crisis thing. Most of my inspiration comes from WEQX out of Manchester, one of many good radio stations near us (also see WMUD and WRMC). I’ll listen to music once in a while when working, or when the news isn’t on. (Like the Old Chapel Road annual planting? Brought to you by the last album I bought: The Pierces- 13 Tales of Love and Revenge) I hear a song I like, I download it from iTunes, and presto. So the list won’t be best albums, as I mostly buy songs. And I have no idea if they came out in 2010 or not, but that’s when I bought ’em.

99 Problems-Hugo. Banjo is like bluegrass in general; a little bit goes a long ways. This remake of a hiphop song has the perfect amount of bluegrass funk. One of my kids likes the song cause she’s got one of those Middlebury Quidditch shirts that says “I’ve got 99 problems and a snitch ain’t one”.

Percussion Gun-White Rabbits. It’s all about the drums sometimes, and this one is much better than the other song I’ve been hearing a lot, Kick Drum Heart.

Crystallized- The xx. I’m not sure if this is a love song or not. It’s a heck of a duet, though, with almost contrasting harmony miraculously sounding good, almost great together.

Blue Blood Blues-The Dead Weather. I’m a sucker for Jack White-he’s good in everything he does. Dirty, nasty, old fashioned rock here.

The Ghost Inside-Broken Bells. Most listeners would probably recognize their first popular song, The High Road, but this one’s better. Half of this group was in The Shins, so that’ s probably why I subconsciously liked it.

Oh My God-Mark Ronson featuring Lily Allen. iTunes says this came out in 2007, but I’m including it on my 2010 list because I still run to it quite a bit. Take a good song, add some killer brass riffs, and presto, instant classic.

Dog Days are Over-Florence and the Machine. This song was starting to get WAY overplayed, until I saw a YouTube video of a baby in a car seat loving it. Now I can almost hear it constantly.

Cobrastyle-Robyn. This one came out in 2005, but I just heard it this year. I had been running to the origninal, by the Teddybears, and that’s good too, but this is a great cover.

Latest Heartbreak-22-20’s. Remember above about the drums? Same comments here.

Ruby-Kaiser Chiefs. This is the first song on one of my running mixes-it’s swift kick in the keister when you’re not in the mood to run. The Kaiser Chiefs also did the original to the Lily Allen song above, but she did it better.

You Got Me-The Crash Kings. Grungy.

Dominos-The Big Pink. Another good starting song.

Help I’m Alive-Metric. Unfortunatly, much of my running takes place at 5 in the morning, and this song is great in a super-creepy-in-the-dark sort of way. The first time my kids heard this song they thought she was singing”Help I’m alive, my heart keeps beating like a hamburger”

Kids-MGMT. I bought this one for my kids, ironically. Good beat.

Battleflag-Lo Fidelity Allstars. This is an older song, I think late 90’s. More electronica dance than anything else, but good running pace.

Handlebars-Flobots. Rap is definitely where my mid-life crisis shows through, but this is a rap song with plucked violin and trombone, so there.

Cupid’s Chokehold/ Breakfast in America-Gym Class Heroes. I’m really showing my age when I admit I’m a sucker for a good Supertramp remix, aren’t I?

Airstream Driver-Gomez. I’ve saved one of the best for last. Well done.

That’s enough I guess. What am I missing?

Annual Review

Regular blog readers (all four of you or so) probably don’t realize I can read about you as well. Through the wonders of an add-in on the blog called Blog Stats, I can see not only how many people are reading pages on this blog, but what pages they are hitting. It can be kinda funny.

I can use the information almost like a forecast. My post a year or two ago on Forecasting a Nor’easter tends to get many page views as a storm comes up the coast-it’s one of the only places where you can look up exactly what that “benchmark” is the forecasters are always mentioning. Similary, do a web search on Pagoda Dogwood, and Google will probably lead you here.

It can be humbling, though. Some of my favorite posts have been the least popular, showing the lowest number of page views. Like Black Eyed Susan-one of my favorite plants, and favorite posts. Next to no one read that. Or Plants of a Mis-Spent Youth-the secret I barely want to tell anyone about how I’m filling Middlebury with unusual plants. My very least popular posts, though, have been on Annuals.

We don’t plant a lot of annuals at Middlebury-it’s a space and time thing. It’s best to plant annuals at the end of May and beginning of June, when our department is busy with Commencement and reunion. And with 200 acres, where would we stop? But we do have a couple of prime locations where annuals really brighten an otherwise boring area, and they’re fun to plant. In the past I’ve written about what we planted, thinking that plant geeks like me care, and would want to read about them. Well, site stats say they don’t.

So I skipped it this year. Our normal plantings on Old Chapel Road and the front of Johnson were as popular as always, based on comments from people walking past, but I never posted about what they were. Unlike my own garden, where I sure as hell wished I’d kept track of all the names of the daylilies I’ve planted, I do keep careful track of what we plant at Camp Midd, and naturally I watch carefully. So this year, I thought I’d actually review what we planted, and how well they grew.

North end of Old Chapel Road

I was in the retail garden center business long enough to see so many plants come and go I couldn’t even keep track of them. Gardeners are trained well to plant something new, something exciting. My new role as campus horticulturist requires consistency. I need to know that what I’m spending our budget on is going to work, is going to grow and flower for reunion, language school in the summer, and last through fall family weekend in September. But the plant geek in me likes new things, so clearly I’ve been well trained. And don’t forget the marketing in greenhouses-plants are bred now to look good in little pots and six packs very early, so they sell well. And nobody writes or reviews how well they grow once they’re out of they’re coddled existence.

(Side note: Greenhouses are not a coddled existence, but it is a good phrase anyways. During my first experiecence with commercial greenhouse production I couldn’t believe how harsh the greenhouse magician treated the plants. In fact, I wasn’t even allowed to water. The worst thing to do to a greenhouse is to water it. Most plants in greenhouses die from fungus and rot, the pestilence of over-watering. My boss would smile upon casting his gaze at a greenhouse full of plants just starting to wilt. You can fix that with water. You can’t fix a root rot so easily.)

I have some old faithful plants I put into the annual plantings every year here. Mostly yellow and gold. The official Middlebury color is a very dark blue, which make it easy for a color wheel challenged horticulturist to play off of that with bright yellows and golds of summer flowers. My wife wanted to paint our house a dark blue, and brought the bloom of the Tiger Lily that came planted in front of our house down to the paint store to pick the right shade-she’s taught me more about color than four years of Plant and Soil Science at UVM ever did. Sadly, there is no Middlebury Dark Blue flower, at least none I know. That’s why the Middlebury College sign across from Admissions gets yellow and gold flowers. (including Black Eyed Susan, you did read that post, right?)

This year, at the end of Old Chapel Road, by the stone pillars, I went with some standbys, and some new flowers. Most impressive this year were the Diascias, ordinarily a finicky flower. I tend to think fo them like a pansy, better in the cool springs and falls, not so great in the heat of the summer. This one a banner year, though, with a pink Darla Appleblossom from Goldfisch blooming all summer long next to the road

Diascia 'Darla Appleblossom'

and a great Darla Orange Diascia from Goldfisch in the front north side.

Diascia 'Darla Orange'

Something everyone should plant more of is an annual with a terrible name, Scaevola. Proven Winners is trying to give it the rather bland common name of Fan Flower, so I guess that’s better than the latin. I used to love selling this plant in a hanging basket, as it’s as nearly foolproof . I’ve seen this plant go into full wilt, hanging over the sides of the pot looking for the compost bin, but with a quick drink of water covered in full blooms in 3 days. Mostly seen in a pale-ish blue, this year I used a really pretty white, and I never drove past and saw this plant out of blooms.

Scaevola 'Whirlwind White'

A flower I always fall in love with in the greenhouse, and a good contrast to Middlebury blue is Marguerite Daisy. Not a great choice for annual beds, though, at least not for us. Many annuals cycle-blooms like mad for several weeks, then next to none while it sets seed (or thinks it does, as most hybrids probably don’t anymore). In a container, or in the hands of someone with more time on their hands than I, this plant will do well, as snipping off dead flowers keeps it blooming well. I like the Vanilla Butterfly cultivar from Proven Winters, in a nice pale yellow. It also comes in a gaudier bright yellow, and a pale pink that only looks good for 3 days in the greenhouse, and then never again.  Here’s the Vanilla Butterfly on a good week. Look at the picture above of the Middlebury College sign for a bad week. Look hard, it’s in there.

Argyranthemum 'Vanilla Butterfly'

Speaking of falling in love in the greenhouse, every year for the last several I’ve been planting Angelonia, Angelonia angustifolia. I fall for the Proven Winners ‘Angelface Blue’, even though they don’t trust us with the latin, and are calling it Summer Snapdragon. This is beautiful in a little 4″ pot, all upright and full of dark blue, almost purple blooms. It does sort of look like a snapdragon, with a couple of bloom spikes sticking up across the greenhouse bench. They get planted, and promptly fall over on the ground, staying there for several weeks until the base of the plant sends reinforcements. I’ll probably keep planting it, though, as there is nothing like a summer romance.

Angelonia 'Angelface Blue'

There were two dissapointments in the bed this year, one of which I should have known better. Osteospermum (latin and common name this time) is another of those very popular spring greenhouse flowers, and it’s been getting the royal treatment from hybridizers ever since. The problem is that they are like a pansy, only worse, gone mad, only blooming in the spring and fall, and going on vacation in the heat of the summer. We planted a Proven Winner called Lemon Symphony, in a nice pale yellow with a purple (!) eye. It was so sad looking at picture time in late August, I didn’t even take its picture.

Another plant that does not work in a planting bed turned out to be a foliage plant, Pseuderanthemum ‘Black Varnish’. Great cultivar name, as the thick glossy leaves are a dark, almost black red. This would be a great plant in a container as a focal point, standing tall in the background. Massed together in a outdoor bed, with no side shoots, it just looked a little silly. Not that there is anything wrong with that. Maybe if I’d pinched the tops of the plants off in early July to promote branching they might have filled out some.

Pseuderanthemum 'Black Varnish'

Not dissapointing, but not thrilling, was a Calibrachoa called ‘Noa Yellow’. The common name is Million Bells, for many tiny petunia shaped flowers that cover the annual, but Million Bells may be a Proven Winner trademarked name. Some of the Calibrachoas grow like crazy, while some never really grow much after their greenhouse sojurn. ‘Noa Yellow’ ran the middle course, blooming well, but never really expanding out into the garden to fill space. Chalk it up to another plant for containers.

Sustainable Landscaping

While doing a post on the Sustainable Sites Initiative for the Atwater Landscape contest blog Turf Battle I’d remembered I also wanted to write about a homeowner version of this document called Landscape for Life. I first read about this project at the wonderful Garden Rant blog, then immediately went to read the document. I’d been following the work of the Sustainable Sites inititive for a while, and am over-joyed to see a less ‘industrial’ application.

Like the Sustainable Sites website, the Landscape for Life website is a great resource in an of itself, but the true reading is found in the large document, available for download. Highly recommended  winter reading for your inner gardener.

Magic (Salt)

We’ve had quite the snow week, even though it rapidly disappeared in the rain Sunday. I’ve written about how we remove snow in the past, it’s one of my favorite posts. And what I said certainly still holds true, that a job well done means that no one really noticed we did anything at all. Presto, the roads and sidewalks are clear. This year, we’ve made it a little easier for ourselves, and for the environment, with clearer and safer surfaces to boot.

The issue with snow and ice is always one of traction. Getting rid of most of the snow is relatively easy. Shovels, plows, snow blowers, brooms, even backpack blowers are all used, depending on conditions. The challenge in the winter is the last 1/4″ or so, the snow or ice remaining that doesn’t want to go anywhere. The problem is warmth, and the fact that the very first snow that falls on sidewalks or roads bonds to the surface, and can be very hard to scrape away and remove. This is what makes winter treacherous, and what makes walking and driving difficult.

In the past, Facilities Services has used sand, and a lot of it. Spread on top of this bonded snow/ice hard pack, the sand gives traction on top, making the walk or road a little less slippery. Most of the time. Sand comes with costs, though, some obvious, some not so much. Sand use in winter is linked to phosphorous loading in streams, sedimentation buildup in catch basins, retention ponds, and waterways, and even airborne pollution, as the cars and trucks driving across the sanded surface grind the particulates into finer particles and allow them to become airborne. But the worst part of sand? The carbon footprint, not only in spreading a heavy product, but repeated trips to refill, the continual scraping of the surface to try and remove the leftover hardpack repeated over days, and worst of all, the massive amount of work and fuel required in the spring to clean all the sand up. After all that work, there is still snow and ice left on the walk. The sand seems to disappear, moving off the hardpack to the edge, and the walks are slippery again.

The other solution to the ice problem is to get rid of it, frequently by melting it. In a bulk scale, this usually involves rock salt. Ever make homemade ice cream? Rock salt lower the freezing point of ice, so that it stays liquid at a colder temperature, allowing the milk to freeze. Applied to a road, the salt thaws the ice or snow hardpack, where it runs off as water, drying the road. This certainly has it’s problems too, not only in the carbon footprint to get salt across the country, but in effects both in water and soil of excessive salts. There are other ice melter products, from calcium chlorides to magnesium blends used on airport runways, but most bulk applications still rely on plain old salt.

Facilities wasn’t satisfied with sand, as anybody walking across our sidewalks in the past might attest to, but we weren’t sure about salt, not wanting to make an environmentally worse choice. (It’s neck and neck, actually, between sand and salt, if you actually take the time to weigh the pros and cons.) A couple of years ago we started using Ice Ban as a pretreatment. This liquid is the byproduct from food manufacturing (I believe our source is actually from beer), and sprayed on sidewalks and roads before a storm can prevent the dreaded bond from forming, allowing the snow to be completely removed. This is tricky, though, as conditions need to be perfect in order to apply, and this only seems to be about 2/3-3/4 of our snow events. Then we discovered magic.

Magic Salt is ordinary rock salt treated with ice ban, or an equiviant. This agricultural by-prodcut gets sprayed on the salt, turning it brown and giving it a somewhat funky smell. It makes the freezing point of water drop even lower, meaning less treated salt is needed to melt the equivalent amount of snow or ice. Some estimates claim 30-50% less. And much much less sand/salt mix, up to 3 times less. Less product=less carbon. And we’ve got cleaner sidewalks. This is our first year of trying Magic Salt, and so far we’re impressed. But don’t take my word for it, the proof is in the pictures.

Here’s a sidewalk treated conventionally with ordinary rock salt (not by the college). Yes, the sidewalk is clear, but note not only the chunks of excessive salt remaining, but the white residue of the salt on the walk. It’s very easy to over apply salt.

This is one of our walks, treated with Magic Salt. Very clear, but notice there is no excess salt on the surface, and no white buildup of salts on the sidewalk either.

One night this week it snowed on top of cleared sidewalks in the middle of the night, and night time temperatures were in the single digits. Temperatures this cold are below the effectiveness of straight salt, it just won’t melt the snow. The sidewalk above was treated with straight rock salt the day before, and you can see the bond that formed between the walk and the snow. There are footprints in the snow above. Compare it to the the picture below.

This sidewalk was treated with Magic Salt the day before, and, while it has received more foot traffic than the walk above, you can still see how there is no bond formed. Even walking on this sidewalk was more pleasent, and not as slippery as if the snow had bonded down. And with this type of surface we can…

Sweep the walk clear. A broom on one of our tractors came along and in no time at all discovered the bare surface again.

Tree Hazards and Removals

How do we decide when to remove a tree?

It’s the hardest part of our job here in the landscape department, deciding when to give up on one of our trees, and schedule its removal. Some of our oldest trees on campus have their life span measured not in years, but in centuries, so removing one of our noble specimens is very difficult. Even taking down a little young tree makes us sad. We obviously can’t remove a tree just because it doesn’t look quite right, or is in an inconvenient location-our bar is set higher than that. We look at tree risk, the factors that make a tree hazardous.

Students in my Winter Term class learned a simple definition of a hazard tree. A tree is a hazard if it has something to fall on. A tree needs a target to make this dubious list. Sadly, this isn’t much of a guide for us on campus. As you’ve probably noticed, we’re a target rich environment-between buildings, other trees, sidewalks, roads, power transmission lines, sculptures, squirrels, bike racks, students, staff, parked cars, professors, and light poles, we’ve got our share. We certainly prioritize them, and may speed removal of certain hazards quicker than others, but we assume that all trees on campus need to be watched pretty closely.

This fall the landscape department made a special project out of looking for hazardous trees. We surveyed about 2/3 of our 2275 mapped trees, specifically looking for hazardous defects, such as a crack or a split, something that could potentially make the tree fail and injure someone or something. And while it is certainly true that if you start looking for problems you can find them, in our case we identified only 120 trees that met our definition of hazardous, less than 5% of our population.

Of these 120 trees or so, 60% are maples, with Sugar Maple itself making up 40% of the hazard trees, double their representation in the population, as maples make up about 30% of our total. This is shocking, for a state whose tree is the Sugar maple, but not surprising, as Maples, Sugar in particular, are very intolerant to urban conditions, root compaction being one of the worst.

A hazardous tree comes in varying degrees. It’s like having a history of heart trouble in your family-being a hazardous tree is not a sentence of doom, just a cause for, well, not alarm, but extra vigilance. The majority of our hazardous trees will have risks mitigated by good care, such as corrective pruning, cabling, bracing, and simply close monitoring.

There are, of course, trees where even the best of solutions aren’t enough. Generally, these are trees arborists would call ‘over-mature’, or past their expected life span. While a tree in the woods can slowly fall apart and die without any thought to dignity, on campus we can’t wait for catastrophe to happen. Unfortunately, as would be expected, the majority of risk trees are in the older areas of campus, places where similar species and ages are planted together. A good example of this would be the east side of Voter Hall, where several large Silver Maples have serious problems, but make up the majority of the tree canopy.

So of our 120 hazard trees on campus, 6 are slated for removal this year.   These trees contain flaws so egregious that no amount of fixing would make them safe, so it is time to let them go. As is our custom most years, we try to schedule large tree removals over Holiday break-chainsaw and chipper noise during finals isn’t conductive to study. I’ll post some pictures in the next couple of days to show the trees we are removing and why. I think you’ll find it interesting, and you all may want a chance to say goodbye.

New Breadloaf Weather Station

Thanks to Environmental Council, Facilities Services has installed a second weather station, this one up at Breadloaf campus. It’s hanging on the side of the Laundry shack, next to the really cool old telephone booth. We use weather information from the station on main campus all the time, from worrying about snow removal to tracking growing degree days. Now, not only will we be able to do that for Breadloaf as well, but now us Nordic skiing addicts will be able to plan our waxing for the day on the drive up.

For now, the best place to see the weather information is on the Weather Underground, where we are live streaming the information. They generate a page for the Breadloaf station, as well as Main Campus.

What a Storm

“No enemy but the weather, and the wind, the wind, the wind.” Michael Carey, from “The Thing about Farming”, The Noise the Earth Makes.

We had some wind yesterday. I’m thinking you noticed. Peak wind gust at our Middlebury College Weather Station was recorded at 51 mph, but what I found most impressive was the sustained wind speeds, wind speed averaged over the course of a minute. The highest recorded was 47 mph, but between about 2:30 and 4 the wind averaged between 30-45 mph. That’s impressive.

As you may know, wind is formed by air being pushed between two fronts. Yesterday a strong low pressure system pushed off high pressure off the coast, and the great difference in pressure and speed of the approaching front caused our extreme winds. Looking at the weather graphs for yesterday, you can see the barometric pressure was dropping as the cold front approached, and see the wind speed increasing. The front passes us at 4, and the wind speed dies down.

Norway Maple

I’ve been thinking a lot lately about one of the more contentious trees in our urban forest, the Norway maple. Late this fall, while the leaves were still turning, I recently closely inspected over ⅔ of our campus trees, looking for problems, and Norway Maple kept appearing in the problem lists, with similar patterns of failure.

Norway Maple-healthy young tree
Some would say this is to be expected. Norway maple has been an extremely overused plant in the North American landscape, a victim of its own success. 100’s of cultivars have appeared over the years, including one of the most popular shade trees, Crimson King Maple-what most former customers of mine would simply call “Red Maple”, for its dark red leaves all summer long.
John Bartram, one of the fathers of early American botany, introduced the Norway maple in 1756, after receiving seedlings from Philip Miller in England, and started selling them in 1762. The trees remarkable adaptability to varying site conditions, including a broad tolerance of soil texture and pH, made it a popular tree among early arborists and gardeners. And a knack for sending out sports made it one of the first trees to get cultivars selected from it.

Norway Maple,  Acer platinoides,  flowers attractively in the early spring, late April here, with clusters of yellowish green flowers appearing before the leaves, each flower about ⅓” in size, but held in large clusters called corymbs, completely covering the tree. Norways are actually one of the most attractive early flowering trees. Bright yellow fall color can frequently be seen, in years when Tar spot doesn’t decimate the crown foliage.

The flowers turn into large seed pods called samaras, with a pair of seeds held in the center, and large flat wings spreading to each side. Split in half, and each side will helicopter towards the ground slowly, or alight in a breeze and fly for some distance. The wings of the helicopter extend around the seed, and can be opened like a book, where the milky white sap inside can act like a glue, allowing the samara to be attached to one’s nose, where it can stay stuck until nap time.

This milky white sap is a great way for the confused to identify Norway maples, as the similar sized Sugar and Red (Swamp) maples have a clear sap when broken. Spend some time with them, though, and identification becomes easier. The bark is a dark gray, and is ridged and furrowed, unlike any native maple. The leaves are large and dark green, larger than any other maple around, and while similar to Sugar maple, are flatter at the base.

It’s the leaves that cause many of the problems of the species, a victim of their own success. The size of the leaves create a super dense shade, making growth for grass underneath nearly impossible, but also for any interior growth on the tree itself. All the leaves on a Norway maple, and therefore all the growth, is on the outside of the tree. This is a red flag in the tree structure world, where all the end weight of the tree, and all of the wind load, is not shared throughout the tree, but, being held at the ends of the branches, and can be prone to breakage. Fortunately, the wood is fairly strong, and failure is more often seen in bad branch angles. The bare interior of a Norway, though, to me, is as distinctive an identifying characteristic as anything else.

Trunk Failure from Bad Branch Attachments

The dark dense canopy from the leaves also aid in the invasiveness of the species. Norway maple has been outlawed for sale in southern New England, and will become so in Vermont in a couple of years. The shade tolerance, in addition to its own dense shade, and its shallow root system makes the tree a fierce invader in the forest ecosystem, out-competing native maples in the understory, and inhibiting native seedlings (Galbraith-Kent, S. L. and Handel, S. N. (2008), Invasive Acer platanoides inhibits native sapling growth in forest understorey communities. Journal of Ecology, 96: 293–302. doi: 10.1111/j.1365-2745.2007.01337.x) . The shallow roots also hinder the growth and development of native forest flower species.The tree itself hosts less native caterpillars than other native maples, and North American mammals don’t recognize the seeds as a food source.

Norway maple gets its name from the northern end of its native range, and the population extends through the Caucasus and Turkey. There, the tree flowers 3-4 weeks earlier than the similar Sycamore maple, and is thereby kept in check, as both trees are insect pollinated, but the earlier flowering means only 5-15% of the seedling forest population seems to be Norways. Normal longevity for the species only seems to be 100-150  years, although trees in it’s preferred habitat, the Balkan peninsula, lives to about 200.

Our campus trees seem to be failing all at about 100 years as well, for a variety of causes. As mentioned above, Norways seem to be prone to bad branch angles, where cavities form and cause holes in the branches and trunk. Another problem with the tree seems to be a propensity towards girdling roots-roots that circle around the trunk underneath the ground, choking itself off. Norways make up about 10% of our tree population, but account for more than that in shade canopy, so, while they are invasive, we clearly can’t actively remove them. Some younger trees are in front of Forest Hall along Route 125, as well as in front of Emma Willard. The largest specimen is on the north side of the Axinn Center, a tree held together by a jungle of cables up in the crown.

Over-Mature Norway Maple at Axinn

Why?

7-18-6.

Not a fertilizer label, but an accounting of the fall semester at Middlebury. Seven-the  number of weekends in a row we’ve seen vandalism against trees. 18-the total number of trees affected. And 6-trees killed outright.

We come into work Monday morning, and, in addition to picking up the inevitable and ubiquitous litter and detritus from the weekend, now survey the damage as well. I was not writing of it, hoping to sweep our problem under the rug, hoping that these acts were random, solitary, maybe just an aberrant mutation on an otherwise pristine campus, a passing social deviation that would go away on its own.

And I’m preaching to the choir, here, after all. I’ve discussed vandalism in the past on Middland, and am quite frankly a little sick of telling the tale. I’ve reported this problem to my superiors, and they’ve approached community council. And I was going to get on with life, and write posts on annuals, the Sustainable Sites Initiative, and put some more work into Turf Battle.

Last night, Dean Shirley Collado wrote a piece on One Dean’s View called Plates and Privilege. We’ve all heard about the missing plate problem, thanks to Aunt Des and the great communications department. But Shirley’s take is different, and had me thinking all night (well, until 9:30 or so, I can’t seem to stay up like I used to) about privilege. Let’s let her say it best:

I would like to call students to action to think more critically about the human face behind the dish problem. Think about what it says about us as a community when these small acts of thoughtlessness create a collective problem that impacts all of us in a negative way. This thoughtlessness speaks volumes about what kind of people our students are going to be when they leave this institution.

So, I thought, our tree vandalism is a problem of privilege, like the many beer cans scattered around on a Monday. It’s easy to take trees for granted, and yes, sometimes they do get in the way (I’ve wondered on one or two broken branches if the offender was tall-sick of running into the same branch every day).  But then I cleaned up some of the damage today, and came to a different conclusion.

We have a problem of violence.

Pictures won’t even do it justice, and even my words won’t. In the service building? Come by my office, I’ve saved a couple pieces of broken limbs. But let me try to explain what’s going on here.

The offender (I hesitate to use the word ‘student’, as surely this individual isn’t really learning anything here) is breaking limbs off of trees. Serious limbs. I climb trees, and, while I still resemble the pasty geek I was in high school, I’ve jumped a couple of weight classes. Limbs broken would hold me and my chainsaw with room to spare. Limbs that are not just snapping off, but need to be bent, wrenched, moved back and forth hoping to break 3” of bark and wood to separate it from the tree. Entire small trunks of immature trees not only bent to the ground, but shaken, trampled, twisted and torn, sometimes breaking completely, sometimes left hanging , or lying in ground, waiting for a chalk outline to surround it. This is an act of rage, of violence, well beyond wanton destruction of property, senseless passing violence against an animate object incapable of screaming or defending itself.

A 3” limb, counting rings, is probably very well older than the person breaking it off.

Monday will come again, and again we’ll go out, willingly pick up the remnants of a privileged life, but hope and pray that no more violence has befallen our silent friends.
