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…

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…
