Opinion: Wildlife Need More Adirondack Clear-Cuts

Bicknells thrush In the September-October edition of the Adirondack Explorer, ecologist Charles Canham says there are legitimate concerns about over-harvesting trees in the Adirondack Park, and that there is no good ecological or silvicultural rationale for clear-cuts.

I must disagree with these suppositions by Mr. Canham. With millions of acres of state land preserved within the Adirondack Park and never to be managed (harvested), Adirondack Park Agency oversight of larger clear-cuts on non-state-owned lands, and best management practices in place for forest harvests, there should not be great concern for over-harvesting. This is not the days of old, when massive cuts were done on steep slopes with no effort to stabilize the soil. Methods are much more environmentally friendly these days. » Continue Reading.

Run, Dorothy – Emerald City is Falling

Watertown is poised to become an Emerald City, but that’s not good news. Jefferson and Lewis will soon be Emerald Counties, and St. Lawrence County began the process of change two years ago. Unfortunately, this kind of transformation does not involve happy endings.

When the emerald ash borer (EAB) kills an ash, something happens never before seen — the tree becomes brittle and hazardous very quickly, beyond anything in our experience in North America prior to this. Municipal leaders, DOT officials, woodlot owners, loggers, farmers and other land managers need to be well-informed in order to stay safe and avoid liability. » Continue Reading.

Opinion: The Adirondacks Does Not Need More Clear-Cuts

Bicknells thrushNew Yorkers think of the Adirondacks first and foremost as a preserve, but working forests on private lands have always been an important part of the Park. There has been a sea-change in ownership in recent years, with timber investment firms now controlling the bulk of working forests. And harvest rates throughout the Northeast have been steadily increasing.

So much so that logging rates are at unsustainably high levels in many places. This is most readily apparent to the public in the growing acreage of clear-cuts in the Adirondacks and Maine. But it doesn’t take clear-cutting to overharvest a region’s forests. Forest biomass is declining in Connecticut due to high-grading—the highly selective logging of just the largest and most valuable trees. To most foresters, that is a far worse sin than clear-cutting. » Continue Reading.

DEC: Avoid Caves and Mines to Protect NY Bats

At the start of National Bat Week, the New York State Department of Environmental Conservation (DEC) has urged outdoor adventurers to suspend exploration of cave and mine sites that may serve as seasonal homes for hibernating bats.

Human disturbances are especially harmful to the State’s bat population since the arrival of the disease known as white-nose syndrome, which has killed more than 90 percent of bats at hibernation sites in New York. » Continue Reading.

Boxelder and its Namesake Bugs

Boxelder bug Comedian Rodney Dangerfield’s shtick was the phrase, “I don’t get no respect,” always followed by one of his great self-deprecatory one-liners.

If Rodney Dangerfield were a tree, he might be Acer negundo – the boxelder, which also gets no respect. When boxelder isn’t being ignored, it’s being disparaged, dismissed, or damned with faint praise.

Boxelder, also known as ash-leaved maple, can be a fairly big tree: it can grow 50 to 75 feet tall and more than two feet in diameter, though it often has multiple trunks. » Continue Reading.

Study: Widely Used Repellent Lethal For Salamanders

Salamander Insect repellents containing picaridin can be lethal to salamanders. So reports a new study published in Biology Letters that investigated how exposure to two common insect repellents influenced the survival of aquatic salamander and mosquito larvae.

Insect repellents are a defense against mosquito bites and mosquito-borne diseases like dengue, chikungunya, Zika, and West Nile virus. Salamanders provide natural mosquito control. During their aquatic juvenile phase, they forage on mosquito larvae, keeping populations of these nuisance insects in check. » Continue Reading.

Tiny Owls Are On The Move

Saw Whet Owl Every autumn, when the air tastes of apples and leaves crunch underfoot, my thoughts turn to tiny owls – northern saw-whet owls (Aegolius acadicus) to be exact. Just eight inches in length with a round head and bright yellow eyes, the saw-whet is arguably New England’s most endearing owl. Deer mice, I suspect, would beg to differ.

Saw-whets are small, secretive, nocturnal, and very often silent. As a result, until relatively recently, their migration patterns were poorly understood. Project Owlnet, a network of researchers spanning much of North America with a particular concentration in the northeastern U.S., is changing that. » Continue Reading.

Animal Intelligence: Head of the Class

brain sizesWhen the topic of animal intelligence comes up, we might argue whether a crow or a parrot is the more clever, or if dolphins are smarter than manatees. Seldom do we ascribe smarts to life-forms such as insects, plants or fungi. And it is rare indeed that we question our intellectual primacy among animals. It is true that no other species can point to monumental achievements such as the Colosseum, acid rain, nerve gas and atomic bombs. But that does not mean other species are bird-brained. Metaphorically speaking.

It makes sense that elephants and whales are whiz-kids, given the size of their heads. Depending on species, whale brains weigh between 12 and 18 pounds (5.4-8 kg.), and Dumbo’s cranium would tip the scale at around 11 lbs. (5.1 kg.). Compared to them, our 3-pound (1.3 kg.) brains are small potatoes. What sets mammal brains apart from other classes of animal is the neocortex, the outermost region of the brain responsible for higher functions such as language and abstract thinking. » Continue Reading.

Mallards: The Chevy Impala of Ducks

Mallard Ducks My francophone wife is often amused as I commence à apprendre la langue, like the time I said connard when I meant canard. For the monolingual English-speakers out there, canard means duck, while the rough equivalent of connard is a word that rhymes with “spithead,” and that you don’t want your kids to say. But where mallards and other puddle-ducks are concerned, the two are related. The drake (male) can be an absolute connard sometimes.

The Darwinian principle “survival of the fittest” is not always about who wins the antler fight or arm-wresting contest. Fitness means being well-suited to one’s environment so as to live long enough to reproduce and thus pass on one’s DNA. Above all else, it means being adaptable. » Continue Reading.

Toad Toxin: Don’t Mess with Anaxyrus

american toad When my kids were toddlers, they discovered, quite happily, a toad in a damp corner of their sandbox, tucked into the shade beneath the small, triangular piece of wood that served as a seat. The toad seemed to spend most days there, probably waiting until dark to emerge and hunt bugs and slugs.

Thankfully, back then, we had a more mature dog who was wise in the ways of the world – not the goofy pup we have now, who I’m sure will learn the hard way not to eat toads. Many a clueless canine has clamped its mouth around an American toad – the species found most commonly in our region – only to be introduced to bufotoxins, a toad’s best defense against being eaten. » Continue Reading.

Indian Pipe: Ghost Flowers of the Forest

indian pipe On a walk in the woods in early fall, you may see a cluster of waxy, white stems with tiny, scale-like leaves rising out of the leaf litter or pine needles. At the end of each translucent stem is an odd, bell-shaped flower. This is Indian pipe, named for its resemblance to the clay pipes once smoked by Native Americans and early settlers.

Indian pipe, also known as corpse plant and ghost flower, has an unusual strategy for survival. It lacks the green pigment chlorophyll, and therefore cannot make its own food through photosynthesis as most plants do. Indian pipe and its relatives were formerly believed to live off decaying organic matter and were called saprophytes. However, more recent research has revealed that the plant is a parasite, sucking up nutrients from mycorrhizal fungi in the soil. Trees and mycorrhizal fungi have a symbiotic relationship: the fungi absorb nutrients from the trees; the trees benefit by increasing the surface area of their root systems, allowing them to drink in more water and minerals. Indian pipe interjects itself into this relationship, absorbing nutrients from the mycorrhizal fungi but giving nothing back. » Continue Reading.

DEC Advises Public To Watch for Adirondack Moose

Adirondack moose 3 (DEC Photo)Motorists should be alert for moose on roadways in the Adirondacks and surrounding areas at this time of year during peak moose activity, advises the New York State Department of Environmental Conservation (DEC).

Early fall is the breeding season for moose in northern New York. During this time moose are wandering looking for mates, leading them to areas where they are not typically seen. While this improves the opportunities for people to enjoy sighting of a moose, it also increases the danger of colliding with one on the roadway. » Continue Reading.

Stings and Stingers: An Outside Story

hornet stinging apparatusAs a boy, I was exploring the loft of my grandmother’s barn when I disturbed a bumblebee nest among the moldering hay bales. In my memory, I leap stuntman-like from the haymow and hit the ground 10 feet below running flat out, rounding the corner of the barn then glancing back to see if anyone is in pursuit. There is an angry bumbler coming up fast. I vault the rusty ornamental fence and am steps from the screen door and safety when … I get nailed in the neck. Ow!

When we lived in Louisiana, I scalped a fire-ant nest while mowing the lawn and got stung a few hundred times as the ants swarmed up my legs. Vivid memory. I’ve been stung by several varieties of wasps and, as a beekeeper, I periodically get stung by my honey bees. Yes, it still hurts. » Continue Reading.

Early Success In Grasse River Freshwater Mussel Relocation

East elliptio mussel East elliptio mussel provided by DECNew York State Department of Environmental Conservation (DEC) has announced that an innovative project that is relocating freshwater mussels in the Grasse River during an ongoing river remediation project is showing early signs of success and reporting a 98 percent survival rate.

As part of an U.S. Environmental Protection Agency (EPA)-led cleanup project to remove polychlorinated biphenyls (PCBs) from river sediments, a seven-mile stretch of the lower Grasse River in northern New York in being dredged and capped starting next year. Before dredging begins, DEC is collecting mussels from the river bottom and temporarily placing them in areas that won’t be subject to capping or dredging. The New York State Museum, St. Regis Mohawk Tribe, and SUNY Cobleskill are collaborating with DEC on the project. » Continue Reading.
