I was sitting at home, (I was at work early), watching lightening strike all around us, many up on the ridge of Snake Mountain, some in the fields below. The wind was howling, and sheets of rain poured down. The Middlebury weather station recorded a 20 degree temperature drop in less than a half of an hour, and more than a half an inch of rain in the same amount of time. Peak wind gust came in at 40 mph.
The college weathered the storm ok, but 3 trees took it quite hard. A Green Ash behind Emma Willard (Admissions) took a lightening strike-that was interesting, as it was the shortest tree around, but it was all by itself in the center of the back yard.
Another tree we lost, not surprising, but still sad, was a large Weeping Willow on the northwest side of Battell Beach (the upper Quidditch Pitch). We almost always see Adirondack chairs underneath this tree. The center two stems of this tree had a fast moving fungus that caused a rot in the sapwood of the two center trunks. The sapwood is what carries water upwards to the branches, as well as nutrients throughout the tree, so having this vital structure rot away was a irrecoverable death in waiting. High winds torqued one of the trunks, and broke it away to lean against one of the remaining ones. We removed the tree the next day, before it broke further on someone sitting in a chair.
The final tree may or may not be a casualty, time will tell. One of the large Norway spruces we left in the Main Quad Tree Removal, the most southern one, was hit by lightening. Friends at work in the service building told me it was the most impressive lightening strike they’d heard in a long time. The tree shows a classic spiral scar from the top of the tree all the way down to the bottom root flare. Bark like shrapnel was scattered all over the quad in long 3′ strips, and filled the back of one of our gators. The prognosis of the tree is unknown. The roots seem to be intact-while there is bark peeling on the root flare, it does not seem too bad. Certainly I’ve seen trees recover from worse. We’ll know in a couple of weeks-if the tree is going to die quickly we’ll know soon.
