Drought Stress

Our barely green lawns across campus belie a hard fact this summer-it’s been dry. Very, very dry.

Funny, considering how wet it was in late spring, when it was almost too wet to do anything outside. The High Plains Regional Climate Center (kick ass website for weather geeks!) maps show we have 25% of the normal precipitation in the last two months, that’s a 6″ deficit of rainfall.

60dPNormNRCC60dPDeptNRCC

A general rule of thumb I can’t find a reference for but I always tell anyone is that Vermont plants need a 1/2″ of rainfall per week for optimum growth. We’ve had only about 1″ in all of August, and only 1″ in July. Most of that falling in one day, leaving our clay soils to dry out and become nearly resistant to small rainfalls.

The early leaves you see falling are signs of that. Trees in temperature zones such as ours develop wide, spreading root systems, not going too deep in search of water or nutrients. In fact, much of our campus is on ledge, with very little topsoil available, meaning plants need to go shallow and wide to root into the ground.

(My unsubstantiated theory is that Middlebury was founded where it is because of the ledge-poor soils make poor farmland, and why waste valuable agricultural soils and farmland on something as unimportant as a college? Farmland in 1825 was precious, hard earned space, so let the geeks have the hill, we’ve got crops to harvest)

These wide spreading root systems enable fast, efficient uptake of water and nutrients in poor soils and a short growing season. In ordinary years, this is ideal, but in dry years, this strategy can be costly. As you can imagine, the shallow soils dry quickly, and the plants don’t have the deep extensive root systems to find moisture in the lower soil profiles. Trees are gamblers, and they’ve got a losing hand this year.

Flowers and other perennials show stress by wilting-the curling of the leaves cut down on the loss of water through the stomata (transpiration, if you want to flash back to high school biology). Trees react like that too, but also have the ability to shed leaves. We are seeing this now, and it may cause an early fall. The inner leaves on trees turn color and fall away, a survival mechanism. Inner leaves in the crown are not as efficient, they don’t photosynthesize as well, and therefore are not as “useful” to the tree as the outer, younger leaves. In desperation, the tree will shed the inefficient leaves ,brutally choosing the younger leaves to use the precious remaining water they have remaining.

We’ve had a little bit of rain this weekend, and more is coming, so luck it will come in time to prevent a wholesale dropping of leaves before your parents come up for fall family weekend. Snake Mountain above my house is starting to turn brown along the ledges, though, though, so lower expectations while you can.

Satin Moth

I love getting emails from people concerning the landscape. After all, with more than 300 acres, there are probably things happening I’m missing. And in the chaos that is Commencement and Reunion, I was missing a big one.

Professor Jeff Byers wrote last weekend-

I  don’t know if there is anything you can (or would) do anything about, but there is an oak tree between BiHall and Coffrin that was in the process of being totally devoured by gypsy moth caterpillars!  There were so many that I could hear the hum of their munching under that particular tree.

I went right over. (the joys and perils of instant email on my phone-it was a Sunday.) I was terrified it was the giant Pin oak tree, the one that made the list of the twelve oldest trees on campus. Fortunately, it was one of the Poplars nearby. And was I impressed.

I couldn’t hear the munching, I think they were all fat and lazy by the time I got there. Much like me on a sunday. Not Jeff-have you read his blog? The last time I did a trail run up the wrong secret side of Snake Mountain I came down with Strep. I reached up to one of the many defoliated leaves, and grabbed a caterpillar.

 

Bugs don't freak me out, snakes do.
Bugs don’t freak me out, snakes do.

Jeromy Gardner, our elm guru from Bartlett Tree in Manchester, correctly identified it as Satin Moth. Not worrying, but has a habit of building a large population every so often and completly covering a tree, in this case our White Poplar. Here’s a great article, if you are interested. They were originally thought to only attack exotic poplars, such as Lombardy poplar and European White poplar (what ours is), but now also is seen in forest stands, and could become significant if defoliation occurs for several years in a row. It does, however, have plenty of natural enemies, including parasitic insects, bacteria, fungi, even birds.

So all that remains on the tree are the major veins of all the leaves, everything in between them eaten. I fully expect the tree to re-leaf in a couple of weeks or so. What is even more interesting is the other white poplar about 30′ away, with only a minimal population. The infested one was in a construction zone a couple of years ago. Maybe the stress of root compaction has something to do with this? Or I’ll be writing about both trees being infested next year…

Thanks to Jeff for pointing it out. Maybe I’ll host a ‘trailrun’ of the trees on campus someday this summer. Better start training now.

Emerald Ash Borer Presentation-This Wednesday

Part of my absence from the blog would be teaching my winter term class “Trees and the Urban Forest” again this semester. It’s a great class, in a super rushed sort of way all winter term classes probably are.

As you may well be aware, the Emerald Ash Borer is a small exotic insect invading the country, and is poised to enter Vermont in the next couple of years. It has the potential to eliminate all the native Ash trees from the state. Just on the campus grounds itself we have over 200 large Ash trees that will need to be removed at great expense, and replanted. For a quick explaination, see http://www.vtinvasives.org/invaders/emerald-ash-borer .

Two years ago my winter term class took a draft of an emergency preparedness plan for the eventual arrival of the insect from the State Department of Forests, Parks, and Recreation and completed it for the Town of Middlebury. This winter term we are now drafting the plan for Middlebury College. This includes surveying all the Ash on campus, coming up with options for treatment or removal, giving replanting options, and running a computer model to calculate the lost benefits from these trees, including stormwater and pollution abatement, carbon sequestration, and energy savings.

We’d be honored if you could join us to present the plan to the College community on Wednesday, January 28th at noon, in The Orchard, room 103 in the Franklin Environmental Center. I understand it’s short notice (sorry!) and winter term is crazy in even a relaxing year. Please feel free to email me with questions, and if you know of someone else that would be interested, please let them know!

Fall Arbor Day 2014

An extremely late spring-not warming up until mid May-left our landscape department short on time. We decided to postpone Arbor Day for a fall celebration, which we are holding next week.

Friday, October 10th, starting at 3:00.

We’ll start with a tree tour, this time focusing on the 10 (12) oldest trees on campus, but of course looking at more than that. We’ll start at the plaza at the Mahaney Center for the Arts, and walk through campus, eventually ending up at-

The west side of Battell-the corner of Battell Beach. After looking at the oldest trees on campus, at 4:30 we’ll plant what will be the youngest trees on campus. This is an area that saw a lot of tree vandalism (since cured! no damage this year). We’ll plant a half dozen or so trees on this corner of the beach, forming a little grove of color.

We’ll bring the food, and pre-dig the holes (oh, hydraulics and backhoe, my mistresses in crime), so all you’ll need to bring is a willingness to get your hands and knees a little dirty. Rumor has it there will be ice cream, cider donuts, and cider.

Come for the tree tour, or come for the planting, or join us partway after your classes. I’ve never done a tree tour during foliage season, so if you’ve gone on one before this one will have new stories.

Oh, and someone bring a frisbee. My 14 year old daughter just joined the high school frisbee team, and needs some practice.

Here’s a sneak preview-

The Twelve Oldest Trees on Campus

Middlebury Magazine asked me to help with a story a month or so ago-they were looking for the 10 oldest trees on campus. Naturally, I gave them 12. There were a couple I just couldn’t leave off, and I walk around and still see a couple more I should have added.

Our campus features many spectacular trees, but surprisingly none of them are very old. Charles Baker Wright, Professor Emeritus of Rhetoric and English Literature , in the Middlebury College News Letter of 1931 talks of the story of campus trees, and how early in the history of the college was an old time notion that “trees wouldn’t grow on that hillside”, and how finally in about the 1830’s trees were planted wholesale, so thick that 70 years later Old Stone Row was a ‘veritable thicket’. Other areas of campus were likewise barren of trees, but didn’t have the donations to plant like near the Row. (as always, click on the picture for larger version) (especially to see the guys in the top hats)

Another sad chapter in the arboreal history of Middlebury is Dutch elm disease, which you can read much more about on other pages in this blog. Many areas presently bare of canopy from shade trees are previous Elm locations. This is not all bad-views from Old Chapel Road to Mead Chapel are greatly enhanced by the clear lines of sight.

Trees have a lifespan, like us, and it may be useful to think about tree years the way many people think about Dog years, but with no set figure to multiply.  A redwood is ancient at 2000 years old, Bristlecone Pines date to 3500 years old, while a Poplar tree is old at 40. I’d venture to say an old tree for Vermont is 300, with precious few of them remaining.

A great grandma of all the trees on the Middlebury campus is a spectacular Bur Oak on the north side of the Mahaney Center for the Arts. Fellow horticulturists have estimated an age of easily 250 years old. Even in tree years, this one’s sitting on the porch rocker being waited on hand and foot. Trees like this, particularly oaks, were often left as boundary markers for property, and would be referenced in deeds and other legal documents. Aerial photographs of the area show this tree sitting next to Porter Fields, the combination baseball/soccer fields for years. It was there long before Baseball. I’ve written about this tree before.

Paper Birch is, like all birch, an early successional tree, born to live fast, set seed, and die young. This tree isn’t very old in human years (I’m guessing about 85-90), but a mature birch is only 45-50. Proof that the right tree in the right spot will do wonderful things. This tree would be a grandparent too, one of those impatient ones yelling at the grandkids to keep off the lawn. It is safe to assume this birch was planted by the former owners of the house (the McKinley’s, I think, as that is what we call the house). Paper birch is an extremely popular landscape tree, but prone to many diseases which shorten the lifespan.

Nearby there is an elm along Route 30 next to the field house. I often wonder about all the construction it’s been watching over the years. Our guess is about 175-200 years old, an old survivor from when elms were transplanted from the woods to line the rudimentary roads of the new country. Old photographs show elms lining both Route 30 and 125, and we work hard to save the few that remain. This one’s middle aged in tree years, elms can go for many decades more than this one has been around.

Norway Spruce grow fast when young, and get leisurely in their middle age. The massive Norway spruce north of McCullough was planted as part of a windbreak to protect the athletic fields next to the gym. Photographs from 1890 show already mature trees next to the baseball field, making this spruce easily over 150 years old. This tree is unusual for a Norway spruce in that the main stems are going through reiteration-the bottom stems forming entirely new trees, so looking up from the base into the canopy of this tree one would see multiple trees sharing a single trunk. This is much more common in Redwoods, but clearly this spruce dreams big.

Up the hill from the spruce is a Black Walnut, probably 80-100 years old. It’s a middle aged tree as well, but was part of the extensive gardens of Maude Mason planted to the south of Hepburn. Most walnuts live to about 150 years old, but in the right location (which I hope this spot is) can go over 400.

This walnut was probably planted as part of extensive gardens to the south of Hepburn at the beginning of the century. There was an old cottage nearby as well. The only remnants left of this landscape is a small garden with a plaque on the top of Stewart Hill dedicated to Maude Owen Mason, ‘who planned and planted and tended it from 1916 till 1937’. The garden has since been overcome by Mugo pine, a great example of breaking Tim’s first rule of landscaping-‘If it looks good when it goes in, it’s too crowded’.

The former Battell Cottage, now known as Adirondack House, has two very large Austrian Pines in the front yard facing Route 125. A picture from 1929 shows one of them fully mature, making these an impressive 150 years old or more. In tree years, very old.

3 Black Maples, a close relative of Sugar Maple, remain in a row along Storrs Walk next to Old Chapel. This is the area of campus heavily planted in the 1830’s, and these are the only remaining trees left. At 185 years old they are reaching the end of their typical lifespan, but we are actively preserving them, and hopefully will be around much longer. I’ve written of Black maples in the past.

A photograph from 1947 shows a couple of Sycamore trees planted alongside the road across from the Student Union Building, where Proctor is now. The trees were reaching maturity then, so they are only 85 years old, but one is massively large, once again the right tree in the right spot. So much for trees not growing on that hillside.

Near the Gravity monument by Warner science is a Littleleaf Linden, a tree the British call Lime trees. This one sets the state record for size, with an estimate of age of over 100 years. Its growth rate has slowed considerably; she’s reaching old age gracefully now.

Aerial photographs from 1942 show the Pin Oak to the south of FIC gracing the front yard of a house there, with Chateau in the back yard. We estimate this tree at about 125 years old, a teenager for an oak.

Same aerial photograph-an apple planted next to what looks like gardens. This makes sense, as that entire area of campus has a proliferation of Pear trees similarly old we know nothing about. This tree is probably about the same age as the Pin Oak, but quite a bit older in Tree years.

The oldest tree (in tree years) on the campus is also one of the youngest in human years. Yellowwood is a pretty little tree with Beech like bark and pendulous white flowers in the early summer. The tree tends to branch low with multiple trunks, and falls apart after 50 years or so. Ours is probably 75, with multiple steel brace rods holding the trunks together.

Many thanks to the Digital Media archives, where I spent an enjoyable day in front of the woodstove on the laptop-any use of their pictures should go through them (I’m talking to you, Pinterest) All new pictures are my own.

The Botany of Syrup

Any kid will tell you maple syrup is special, but how special? Is tapping a maple tree like putting a spigot in the trunk? And why maple?

In a wonderful book I’ve written about before by Nalini M. Nadkarni called “Between Earth and Sky-Our Intimate Connection to Trees” she writes of how botanists and tree physiologists have been looking at how sap is produced within maple in the last couple of decades. Like many things, the wild world of maple syrup seems like a freak chance, a perfect random combination of physiology.

A tree’s goal, aside from reproduction, is to feed itself-it’s tough being an autotroph, and a whole lot of work. Photosynthesis takes place all summer long, making sugars for respiration, growth, reproduction, and a little extra. This extra, in a sugar maple, gets stored as starches within the sapwood of the tree. The sapwood, as the name sounds, is the area of the trunk and branches where water and sugars move around, located within the first couple rings of the wood.

As my winter term class hopefully remembers, Sugar maple is one of our “live slow, die old” species of trees. These trees are more shade tolerant, in life for the long haul, and have the foresight to save extra sugar for lean times, such as the introduction of shade or competition. Other tree species, such as Poplar, live fast and die young, and burn through all their sugar like a hyper 3 old, just as prone to growth spurts as an Aspen in the spring.

Early spring brings sun, a little higher in the sky, and better able to warm. Cats in our house know this, moving away from the woodstove and into little patches of sunlight on soft surfaces. Trees know this too, as the sun warms the bark and the wood. The air may be below freezing, but tree surfaces and interiors could be well above freezing. Once the wood gets to be above 40 degrees, enzymes turn these stored starches into sugars, mostly sucrose, and the sugar is now within the sap. This explains the magical sugaring temperature of 40, any warmer and this process stops.

The other freak chance miracle of maple is getting the sap flowing out of the tree. Not all trees can do this. Water is moved throughout the xylem of the tree by capillary action and transpiration, meaning the leaves need to be on the tree for water to move very effectively. That  would ordinarily make for tough sugaring in March and April, except in Maple.

In maple trees the space around the wood fibers is filled with gas, not water like most plants. When the temperature drops, this gas contracts, making space for the sap laden with sugar in between the cells. So water can move upwards from the roots by capillary action without the benefit of transpiration from leaves. This water freezes at night between the cells.

The day brings warm temperatures, melting this ice and expanding the gas, forcing water down the branches into the stems and trunks of the tree. The taps put into tree trunks to collect sap pierce the xylem all this sap is moving through, and water flows down the tap into the bucket or plastic line.

Interested biology students should read another blog, The Botanist in the Kitchen, http://botanistinthekitchen.wordpress.com/2013/03/18/maple-syrup-mechanics/ , and a cool roadtrip would be the Proctor Maple Research Facility of my old school UVM.

 

Free Tree Pruning Webinar

There are no truly awful times to prune a tree, but it’s best to prune in late winter. Early spring would be the only bad time-opening buds and blooms are the low point in a tree’s stored energy reserves, and late winter is warm (ish) but with the leaves off one can still see tree structure well.

So what I’m saying is that, based on the way this winter is going, we’ve got plenty of time left to prune. I’ve written about tree pruning before, but here’s a great opportunity to learn from an expert. The Vermont Urban and Community Forestry program is hosting a series of webinars during lunch hours on tree care, and the first is this Thursday. Tune in and watch V.J. Comai, owner of the South 40 Nursery, talk about tree pruning. Middlebury has bought many of his trees, and, (disclaimer!) he’s a good friend of mine. And truly masterful at the art of tree growing.

Here’s the published blurb-

The Basics of Tree Pruning- March 27th, 12-1pm

When is the best time to prune? What is the proper way to make a pruning cut?  What considerations should you make and what knowledge should you have about a particular tree before pruning?  This webinar will cover benefits of pruning, basic pruning techniques, tips for making a proper cut, and tools and tool safety.  Open to novices and professionals alike!

I highly recommend watching. Sign up at https://vtucf.wufoo.com/forms/tree-planting-pruning-webinar-series/ 

Middlebury’s Elm Collection

Among various tree geeks in New England Middlebury is well known for our Heritage Elm Collection. Elms, of course, naturally succomb to Dutch Elm Disease if we humans aren’t very proactive. We treat 28 old Elm trees, some of which are over 150 years old. I’ve written a couple new pages on them, one a general overview of all of the elms, one a brief primer on Dutch Elm disease and how we maintain the trees, and a final page on the history of the elm tree at Middlebury.

12-Elms

Elms have that classic umbrella shape, but can vary from specimen to specimen. We are fortunate to have trees in a wide variety of sizes and shapes, from the low spreading type like the Dog Elm behind Munroe (yes, we’ve named some of them), to the spectacular high and arching Field House elm. We also have been planting disease resistant varieties, such as Accolade Elm.

I remember a conversation with one of our seasonal employees several years ago, and we were discussing the difference between botany and horticulture. He cited the elm as a good example. Botanically, we will always have elm trees. They don’t die from Dutch elm disease until past their reproductive years, so they will always set seed and produce more young. And looking at them from a geological time perspective, eventually they will develop resistance, although that may be many millennia. Horticulture, though, is as much art as science, and as horticulturists we preserve some of the grandeur of an old elm, and we remember the dignity of the old shade tree as it was, even as we work towards bringing them back.

Tree Map Updated

Having run inside, fleeing from the sub zero temperatures outside today, I spent the day updating our ArcGIS tree map with all the newly planted trees this year, as well as our removals. Seems like a good time to point towards the Campus Tree Map page, or go/treemap. The latest map contains all the trees we individually manage on campus, nearly 2500. Maybe if the cold spell lasts we’ll come up with a smartphone compatible tour…

Water, water everywhere

So we had some rain today.

January is starting out with a bang-it didn’t get above 0 degrees for several days last week, and this morning was 50 degrees and raining. Rain of biblical proportions, with the rain gauge at the track saying .88″ of rain, most of it falling between 7:30-10:30, up to a half inch an hour at times. I’m not going to answer the Middbeat question of “What’s the deal with the weather”, except to say we’ve got some lower atlantic moisture sliding up the coast on the side of the polar vortex in the middle of the country. When low pressure systems like that get squeezed on the sides by intense high pressure, all sorts of funky things happen, like lots of quick rain, or high winds. We had both.

And with the deep freeze last week, storm drains were plugged, iced over, or covered in snowbanks. Rain can’t soak into frozen ground, taxing storm drains even when they are available and working. The landscape department went into overdrive, breaking up ice dams and opening storm drains. The most worrisome spot was solved quickly, that of Voter basement. You know, (or maybe you don’t), that place with all the computer servers. That would be a heck of an excuse for a banner web crash, wouldn’t it?

The northwest door of McCullough, the one that heads either straight towards Munroe and Mead Chapel, or head up the stairs towards Stewart, sits at the bottom of that whole slope below Mead. That entire side slope seems to drain right towards that door. There are several storm drains near there, including what turns out to be a critical one to the right of the door way. This is Jaime and Buzz, wearing hip waders, looking for the storm drain with ice picks and an iron bar. (As always, click on the picture to enlarge)

2014-01-06 09.14.58
And this is the doorway in question, where water was flowing a foot deep through the doors and down the stairs. We actually got the backhoe in there and broke up the iced over snow banks around the entry, and got the water moving down. The plastic and snow was acting like a temporary dam blocking some of the water.

2014-01-06 09.04.34

The Gamut room, in the Gifford pit, started flooding too. That’s Buzz and Jaime again, looking for the tiny little drain somewhere at their feet.

2014-01-06 09.39.20

Yes, I’m the one taking all these pictures. Only barn boots, no hip waders, and I don’t know how to swim.

The drain for this pit is simply down the hill below Mead Chapel. Bet you’ve been sledding over the top of it. Broke the ice around this drain and the pit was cleared in about 15 minutes.

2014-01-06 09.41.58

The last spot we’re still worrying about is on the north west alcove of Battell. This drain is frozen solid, barely flowing at all. We use bags of calcium chloride, and dump them on top of the drain. It acts like a non toxic drain cleaner, flowing down the drain and melting the ice. I’m hopeful this drain will be fixed by tomorrow. I’m not the most patient person you know.

2014-01-06 09.54.58

The true heroes for the day, though, I don’t have any pictures of. There is an entire custodial team known as ‘floor crew’. I don’t even know how many of them there are, but the ones I know on it are all pretty cool. They ran around all day with wet vacs, carpet extractors, blowers, mops, and various other implements of mass destruction. Wherever water was pouring into basements or doorways, they were there, fixing the mess, saving the floors and buildings (and maybe your room!) from the water mess.
