Distressing Colors: Early Leaf Change An Unhealthy Sign

Early leaf colorIf trees held a race to see which would be among the first to have their leaves turn color, the winners would be losers. Premature leaf color change is a reliable indicator of failing health, and the worse a tree’s condition, the sooner it begins to turn.

Precious few places in the world have a fall color show like ours, and the display that northern hardwoods produce each autumn never fails to fill me with awe and appreciation. But when it starts in July, as was the case again this year on some roadside maples, I know those trees aren’t long for this world. In early August even some forest hardwoods growing on thin rocky soils began to show color, which is also unusual. » Continue Reading.

Wild Foods: Cattails

TOS_CattailsLast winter I spent three months exploring East Africa, traveling through ten different countries and covering over 8,077 miles. I was continuously impressed with how much local guides knew about their surroundings, in particular the human uses of various plants. In some instances we could not walk more than ten feet without stopping to learn about another plant and all the ways it could save your life.

This experience made me curious about plants in my own backyard. A quick skim of foraging articles on the Internet revealed that cattails, with their various edible parts, are often referred to as “nature’s supermarket.” I was thrilled to learn that I had a 40-acre produce section right outside the back door. » Continue Reading.

Afflictions Of Late Summer Tree Leaves Only Skin Deep

330px-RhytismaAcerinumDetailUBeing an arborist, I’m of course very mindful of complexion. Things like bruises and blemishes catch my eye, in addition to scabs, cuts, and even those out-of-place whiskers that appear out of nowhere. It sounds like a description of my aging skin, but I’m talking about blotches, warts and cuts that accumulate on tree leaves over the summer.

I suppose if we had to stand outside day and night all season, our skin would develop issues too. Those who work or play much outdoors need to be concerned about skin spots that suddenly show up. With tree leaves, that’s not the case – even the ugliest “skin” condition is generally no cause for concern. » Continue Reading.

Jewelweed: Definitely Not A Weed

JewelweedBy definition, a weed is any plant growing where you don’t want it. To clarify, this holds true only in the garden beds or acreage under your cultivation. “Weeding” flowers in a park planter because they offend your sense of aesthetics is frowned upon.

To a plant, having “weed” embedded right in its name is probably akin to having a “Kick Me” sign on your back. Right out of the box there is bound to be a bit of prejudice against you, fair or unfair. Spotted knapweed, goutweed and Japanese knotweed are all pernicious invasive species, and deserve all the bad press they get. But occasionally an innocent bystander suffers from this name game. » Continue Reading.

Cattails: A Culinary Tale of Nine Lives

cattailsThe two cats at my place have survived many life-threatening traumas such as falls, fights and even the compulsory “devotions” of small children. It’s amazing the hazards they can evade. I think if pets could drive, only dogs would get speeding tickets – cats would always find ways to wriggle out of a citation. Sadly, my contacts in the veterinary field continue to assert that cats have but a single life, and that the whole “nine lives” thing is just a cat tale.

However, the story about cattails having (at least) nine lives is no yarn. An obligate wetland plant, the common cattail (Typha latifolia) is native to the Americas as well as to Europe, Africa and most of Asia – basically the planet minus Australia, all Pacific Islands and most Polar regions. It can be found growing along wetland margins and into water up to 30 inches deep, from hot climates to Canada’s Yukon Territory. » Continue Reading.

Wild Salads: Eat Your Weedies

TOS_wild_saladIn the early 1960s, Euell Gibbons wrote Stalking the Wild Asparagus and introduced millions of North Americans to the virtues of harvesting wild foods. Since that time, gathering wild edibles has become increasingly popular, and in our region, woods-grown delicacies such as ramps and fiddlehead ferns appear in grocery stores each spring.

Yet you don’t have to lace up your hiking boots to enjoy the wild repast. If you resist the urge to use herbicides, you are likely to find a diverse array of edible wild plants growing in your lawn and vegetable garden. » Continue Reading.

Coltsfoot: Eye Candy and Cough Syrup

ColtsfootI haven’t checked with an optometrist, but I may have a winter-related vision problem. When five or six months of winter-white finally give way to a mostly brown world each early spring, my eyeballs hurt – they ache for something bright in the landscape. That’s probably why I plant a few additional crocus bulbs in the yard every fall, and why I search out early-blooming native wildflowers like bloodroot and Carolina spring beauty.

But what thrills me most is how clumps of yellow coltsfoot flowers emerge, long before their leaves come out, from muddy roadside ditches, rail embankments and other sites with a history of soil disturbance. Coltsfoot flowers look a bit like small dandelions, but without any leaves in sight. Maybe it’s the contrast between their bright color and the sepia environs, or perhaps it’s their audacity at blooming so early, but these tiny sunbursts do much to dispel my winter fatigue. » Continue Reading.

A Late Maple Sap Run For Syrup Makers

Sugar Shack 2015In spite of deep snow and frigid temps through early 2015, most maple producers in northern New York have been ready for sugaring season since early February, but they had to wait for the right weather to trigger sap flow.

Until this past week, sap runs in the region had for the most part been sporadic and brief, and producers at higher elevations where it is a bit colder have seen very little action until now. » Continue Reading.

Identifying Trees In Winter Using Buds

Tree BudsEvery winter I teach several tree identification classes to biology students. Cold or colder, it’s always outdoors, but if student evaluations are on the level, it’s always fun. Demonstrating how to tell one leaf-bereft hardwood from another is one thing.

Bark is not the best feature for identifying trees. Sure, white bark means birch, but some birches have black, yellow or reddish bark. Typical bark patterns, such as diamond-shaped furrows for ash, can be absent depending on site conditions and tree health. Cherry and ironwood bark have light-colored horizontal dashes called lenticels, but only on young wood. Not all hickories have shaggy bark. Bark may provide a clue, but it’s not to be trusted as a sole, or even a primary, source of information. » Continue Reading.

Are Snowshoes, Microspikes Damaging Alpine Zones?

BW - Algonquin Snowshoe Trail Close(1)The last several years have seen a boom in winter hiking in the Adirondacks.

The Adirondack Mountain Club and Adirondack 46ers both report more people on the trails in the High Peaks Region. Along with this hiking boom there’s been an increasing number of winter traction devices hitting the market. » Continue Reading.
