Fagus Grandifolia: Beech Gone Wild

american beech treeThe sturdy, long-lived and stately American beech, Fagus grandifolia, has been slowly dying out since 1920, when a tiny European insect pest was accidentally released on our shores. Because of this lethal but unhurried tragedy, many forest tracts across the Northeast are being choked out by too many beech trees.

That’s right, beech decline has led to a proliferation of beech so extreme that in some places it is a threat to the health of future forests. With apologies to all the bovine readers out there, this qualifies as an oxymoron, I’m pretty sure. The ultimate cause of this weird situation is the aforementioned pest, but the proximate cause is a bad case of hormones being out of whack. » Continue Reading.

Nature’s Way: No Fuss X-Mas Tree Recycling

christmas treeIn urban and suburban areas, Christmas tree disposal has come a long way since the bad old days when trees were just compacted with the rest of the household trash and landfilled.

Today, progressive trash hauling companies run special organics routes where they collect and recycle trees, and many solid waste districts have drop-off centers where the trees are chipped. The recycled trees become compost or mulch or bioheat. » Continue Reading.

Quaking Aspen: Capturing Winter Light

aspenNear the house where I lived during my Colorado years, there was a trail that wove through a sprawling grove of perfect quaking aspen trees. In spring, the soft green of emerging leaves was one of the first signs of warming weather. Come fall, their gilded leaves, fluttering in the breeze, reflected in the river, turning everything to gold. Even in winter’s rest, their stark trunks and bare, branching limbs were lovely against a backdrop of deep snow and craggy mountains.

Except the trees weren’t really resting. Little did I know that, even shorn of their leaves, they were still harvesting sunlight. » Continue Reading.

Beech Bark Disease

beech bark diseaseIf you’ve ever seen chevrons on the bark of an American beech, you know you’re looking at a tree that’s been hugged by a black bear. And you’ve likely been impressed with the bear’s climbing ability. And perhaps looked over your shoulder while you were busy being impressed.

But bear-clawed beeches aren’t as common as they once were. The American beech, Fagus grandiflora, has become another member of the North American “trees-devastated-by-imported-pests-and-diseases” club.

Beech trees are still out there in the forest. But many of the big ones are gone, victims of the notorious beech bark disease. It’s a one-two punch — a tiny scale insect bores holes in the bark and a fungus marches in and infects the tree. » Continue Reading.

The Afterlife of Logs

polyporeMy three children have participated in a Four Winds Nature Institute program that recruits adult family members to lead grade-school nature learning. I have worked with several moms and dads over the years to pull together materials for hands-on lessons about communities, habitats, and the natural world. The activities usually ended with crowd-pleasing puppet shows.

During my first year in the program, in a rare moment of advance planning, I read the entire year’s program, and was glad I did: “Snags and Rotting Logs” was scheduled for November, when I anticipated most logs would be frozen or buried in snow. Regardless of frost or snow, I expected that some interesting invertebrates would have tunneled deep into the soil to wait out Vermont’s winter, leaving little more than wood for the students to dissect. » Continue Reading.

Buy Local Christmas Trees, Support Local Growers

Christmas Tree PlantationChristmas trees can be seen everywhere during the holiday season. And, because of this, we often think of Christmas tree farming as a seasonal business, which it certainly isn’t.

To be successful, year-round management and maintenance are needed. And the work is often labor-intensive, and/or needing to be completed under adverse weather conditions. » Continue Reading.

Marcescence: An Ecological Mystery

Young beech trees retain their leaves throughout the winter monthsWe’re blessed to live in an area that offers some of the most beautiful fall foliage found anywhere in the world. And this fall proved to be one of the most remarkably enduring that I’ve ever experienced; the maples, birches, poplars, oaks, and beeches creating a landscape literally exploding in shades of gold, crimson, and orange, which lasted for several weeks.

As cold weather approaches, many species of trees shed their leaves as a strategy to reduce water loss and frost damage. Triggered by hormone change (the balance of auxin levels between leaves and branches), it’s all part of an important and complicated process known as abscission; in which trees seal off the point where the leaf petiole connects to the twig (the abscission layer). » Continue Reading.

Succession: How A Forest Can Create and Re-Create Itself

forest succession A few years ago, I started an observational experiment in forest succession on a couple of acres where we once pastured sheep and goats. Rocky and wet, without livestock it was hard to keep cleared. So, I let the forest recreate itself and just watched the process unfold.

It’s a process that has taken place across much of the Northeast since the mid-1800s. » Continue Reading.

Ecology of Adirondack Wildfires

orthway Fire Just South of Pottersville, April 2012 (Jonathan Sinopoli Photo)There are several natural disasters that can alter the ecological make-up of an area. Widespread tree disease, severe winds, and intense ice storms can all seriously damage or destroy the dominant members of a forest community. However, the most catastrophic force of nature is fire, as a major blaze can significantly impact more than just the composition of trees that cover a given location.

Unlike other natural calamities, fire can wipe out most of the plants that root in an area. In an ice storm, or a major wind event, it is primarily the older and taller trees that are subject to the greatest devastation. Seedlings, saplings, the various shrubs that form the understory and the array of herbaceous plants that grow on the forest floor often benefit from the increase in sunlight that result when the canopy has been drastically thinned or eliminated. During an intense fire, however, the entire plant community can be obliterated. » Continue Reading.

Adirondack Ecology: Wildlife, Wilderness and Dead Wood

Discussions regarding the ecological value of wilderness compared to an actively managed forest often centers around the health and well being of specific members of the wildlife community. While the flora and fauna that a tract of wilderness supports may be strikingly similar to that which occurs in periodically logged woodlands, the relative abundance of the various plants and animals contained in each is often quite different. In wilderness regions, there eventually develops a much higher concentration of those organisms whose lives are connected either directly or indirectly to the presence of dead wood. » Continue Reading.

Seeing Red: Adirondack Foliage Season

We need to figure out how to put Amazon in charge of delivering the weather in the future. Whatever service Ma Nature is using seems to be falling down on the job lately. I don’t believe she intended to give us a record-setting wet summer; I just think all the good weather probably got misplaced on a loading dock in Topeka, or something like that. The spate of mild sunny weather in mid-September, while very enjoyable, was clearly meant to be dispersed over the course of June and July to break up the nonstop rain, some of which was no doubt tagged for 2016. I’d be willing to pay a premium for timely delivery next year.

In addition to widespread euphoria, dusty cars, and dry laundry, another effect of all this sunshine is red leaves. This requires a bit of explanation, given that sunlight typically makes leaves green by activating chlorophyll. This verdant molecule at the center of the photosynthesis miracle is what makes the world go ’round. Some claim it is money, but they need a reality check (so to speak). Without chlorophyll the sole life on Earth would be bacteria, whereas without money we’d merely have to adopt a barter system. Given that chlorophyll and currency are both green, it’s easy to forgive the mistake. » Continue Reading.

Emerald Ash Borer Confirmed in Northern New York

emerald ash borer photo courtesy DECThe New York State Department of Environmental Conservation (DEC) has announced that invasive pest emerald ash borer (EAB) has been found and confirmed for the first time in Franklin and St. Lawrence counties. DEC captured the insects in monitoring traps at the two locations.

DEC confirmed the specimens as adult EABs on August 25. The invasive pest was found within a few miles of the Canadian border and may represent an expansion of Canadian infestations into New York. » Continue Reading.

Only Bury Your Tree After It’s Dead

4H volunteer planting a tree in WarrensburgIn springtime, driving around on weekends makes me sad. Invariably I’ll pass someone out in their yard, shovel in hand, maybe with their kids or spouse, and they have a cute little tree from the garden center on one side of them, and a wicked deep hole in the ground on the other. If I wasn’t so shy, I’d stop and offer my condolences, because clearly they are having a funeral for the tree.

Here’s an arborist joke: What do you call a three-foot deep planting hole for a tree? Its grave. Tree root systems are broad — three times the branch length, barring an impediment — and shallow. Ninety percent of tree roots are in the top ten inches of soil, and 98% are in the top eighteen inches. Tree roots are shallow because they like to breathe on a regular basis. I think we can all relate to that. » Continue Reading.
