It’s normal to tune out all the Chicken Littles (such as yours truly) who run around squawking about this or that invasive forest pest or disease that pose a threat to trees. I mean, how many times can the sky fall, anyway? But the real danger is when we feel so overwhelmed that we throw up our hands. Thinking we can’t make a difference could result in more harm to forests than the pests themselves.

Hetzler: Go Ahead, Paint That Oak Stump
Each time I present on invasive pests, it begins with a slide of Chicken Little, a character who fomented mass hysteria by convincing other animals the sky was falling. It’s usually good for a chuckle. Inevitably I then proceed to unload a barrage of bar graphs, pie charts, alarming statistics, and photos of mayhem wrought by the featured pest. A final slide shows the position of the sky, with arrows in the direction of gravitational pull at 9.8 m/s/s, proof that the sky is indeed falling. For some reason, fewer people laugh at the end. Go figure.
Threats to forest health posed by invasive species are no joke. Yet I think we educators often come across like Chicken Little, squawking about yet another threat to trees.

Oak Wilt And Invasive Species Vigilance
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.
The National Atmospheric Deposition Program (NADP) is a joint effort of research institutions, government agencies and nonprofit groups; their mission is to monitor stuff which falls to Earth that is not some form of water. Since one of the NADP’s tasks is to study tiny particles of pollutants in the air, they will certainly notice if the sky starts to fall, and give us ample time to take cover. » Continue Reading.

The New York State Department of Environmental Conservation (DEC) has announced that oak wilt, a tree fungus that causes disease in oak trees, has been detected in Canandaigua, Ontario County.

Reading Bug Tracks on Tea Leaves
From palm-reading to watching Fox News, humans throughout the ages have sought knowledge through some decidedly irrational means. But every now and then, superstition pays off. For example, studying the pattern of coffee grounds in the bottom of one’s cup, a practice known as tasseomancy, will nearly always reveal that someone forgot to put a filter in the coffeemaker basket. And haruspicy, the study of the fresh entrails of a gutted animal, is consistently right in concluding the animal is dead.
