Terminal Bud Scar: A Tree's Health Chart

Scarred for Life

Paul Hetzler, ISA Certified Arborist

It makes sense that dying trees have terminal bud scars. Sounds like an awful condition – my condolences. But the healthiest trees have them, too (terminal scars, not condolences). It’s a good thing, since terminal bud (aka bud-scale) scars provide an excellent way to leaf through a tree’s health records going back 5 to 10 years.

After a woody plant has its full complement of leaves, and they have hardened off, that…

Treeconomics 101: Early Fall Color Explained

Treeconomics 101: Color-Coded Prosperity



Deciduous trees, lakeside ice-cream stands, and marinas all close down each autumn for the same reason: as daylight dwindles and cold creeps in, their outfits become less and less profitable. At a certain point it makes sense to batten the hatches until the following spring.



Some enterprising holdouts stay open longer; perhaps they have a cost advantage others do not, or have less competition. A few are the opposite, closing shop…

Invasives decreasing carbon stored in US forests

"In addition to cleaning the air and water, forests hold a tremendous amount of sequestered carbon. When trees die and then decay on the forest floor, that carbon is released into the atmosphere, a phenomenon that is one of the drivers of climate change. A first-of-its-kind study by a team that included the United States Department of Agriculture’s Forest Service and Purdue University scientists finds that non-native invasive insects and diseases are reducing the amount of…

Hardly as drastic as the headline would make you think. More like fine tuning and the results really only applicable for Northern hardwoods such as the beech, sugar maples and yellow birch.---LEW…

NYFOA WFL Firewood 4 Charity Initiative

On Weds, Sep 11 a little over two face cords were cut between 9AM and about 11:30.  David D, Jim M., Greg L. and Dave K. worked the shift.  A neighbor from down the street stopped in and worked for about an hour.

During the break we discussed the need for more volunteers.  Get in touch if you would like to volunteer or get more information.…

New Beech Threat Nothing to Sneeze At

Beech Health Update

Paul Hetzler, ISA Certified Arborist

In the early 19th century, a Prussian diplomat asserted that “when France sneezes, the whole of Europe catches a cold.” Things changed, obviously. For a long while it has been an American financial sneeze able to make the world ill. Though China’s economy is projected to soon zip past ours, other countries still put hankies to their faces when the USA coughs.

Canada has been covering up for some time…

Forest Pests are Exploding

Forest Health Forecast

If you’re tired of hearing about new invasive forest pests, I’m right there with you. Seems they arrive at an ever-increasing pace, and the harm potential ratchets up with each newcomer. At this rate maybe we’ll get a wood-boring beetle whose larvae explode, which would put things in perspective. As distasteful as it is to peer at the cast of ugly new characters, it’s better to know what we’re up against.

Novel pests put everyone on a steep learning…

Emerald Ash Borer and Ash Management

Currently there are some ares of NY (and the NE) where the emerald ash borer (EAB) impact has resulted in significant mortality of ash, yet other areas without evidence of mortality. The unfortunate reality is that EAB will almost certainly infest all acres of NY woodlands that have ash, and the result will be widespread mortality. 

There are efforts at finding biocontrol agents, and we can remain optimistic that those will prove effective. These scientists are suggesting that while…

Preventing Anthracnose and Apple Scab

Crabby Apples and Other Complaints

We waited a long time for summer to arrive this year, so it is unfair that some flowering crabapples are turning yellow and brown and shedding their leaves already. Mountain-ash, serviceberry, and hawthorn are also affected by the same disorder. Here and there a few maples and other species are also dropping random leaves, which are for the most part still green, often with patches of black or brown. The latter situation has a different origin, but…

Oak Wilt: You Can Make a Difference

Oak Wilt

It’s hard to be cheerful in a job where I am expected to keep up on each newly arrived or imminent threat from invasive insects, novel plant diseases, and worrisome trends in the environment. Although I typically deflate everyone’s happy-bubble when I give a talk, I’ve discovered we need not fret that the sky is going to fall.

Healthy Forests, Healthy Fish

Fish Forestry

As many anglers know, trees and fish are closely related. Really; it goes way beyond basswood. The relationship is not in the sense of phylum or family, of course. And it's not like the way in which tomatoes and fish were briefly married in a 1996 experiment at Oakland, California-based DNA Plant Technology in an attempt to get a frost-tolerant tomato (or possibly a saucy fish). If it weren’t for tree cover, cold-water fish species would not survive in most of the…

Trees Are Sick of the Weather

Maple Motion Sickness

No one wants to be told they have a weathered complexion, but many trees this summer, especially maples, are looking a bit worse for the wear as a result of conditions earlier in the season. “Leaf tatter” is a term used to describe foliage which may be torn and bedraggled-looking, distorted, sometimes with blackened spots or zones. It can easily look like a disease or mysterious pest is ravaging the tree.

As tree buds open and young leaves begin to unfurl,…

Ice Meadows

(N)ice Meadows

Now that the weather has finally warmed up, we can appreciate ice a little more. Among other things, ice greatly improves summertime drinks, and an icy watermelon is hands-down better than a warm one. And in this part of the world, ice also provides us with unique wildflower meadows. Along stretches of riverbank in the southern Adirondacks, rare Arctic-type flowers are blooming now in the fragile slices of native grasslands that are meticulously groomed each year by the…

Perennial Pet Peeves

Local Volcanoes



When you think about it, landscape trees have a rough life. Firstly they don’t get to choose their neighborhood, whether good, bad or indifferent. Depending where they are planted, they may need to contend with helpful watering by territorial dogs, materials-testing by energetic kids, entanglements with errant kites, or other issues.



Rooted in one spot day in and day out, year after year, they suffer from – well, boredom, I imagine. And from restricted root… Continue

Helping Trees Recover from Flooding

Most Things in Moderation

As a teenager, my son had a saying, whether original or borrowed I don’t know (the saying, that is), which went something like “All things in moderation. Especially moderation.” It would seem Mother Nature took that to heart, and dispensed with moderate rainfall and snow melt this spring. If not her, then maybe it was Creepy Uncle Climate Change. At any rate, the resultant flooding has been heartbreaking to observe.

While I am of course sensitive to…

How tree diversity affects invasive forest pests

Started by Brett Chedzoy in Woodlot Management. Last reply by Brett Chedzoy Mar 27. 1 Reply
