Fishing Season Gets into Full Swing May 1

The New York State Environmental Conservation (DEC) is reminding anglers that fishing season in New York gets into full swing on May 1, the opening day for Walleye, Northern Pike, Pickerel and Tiger Muskellunge. Also, the catch-and-release bass season is now underway on most state water bodies.

Of the warm-water species, walleye are the traditional primary target this time of year; walleye fishing opportunities exist in more than 100 water bodies throughout the state. Over the last five years and in almost all regions of the state, DEC has stocked 60 waters with walleye fry or fingerlings. Through these and other DEC management actions, new walleye populations are being established and others are being maintained or restored. » Continue Reading.

Adirondack Bracket 2010: Blue Line 32 (UPDATED)

We enter the second round of the 2010 Adirondack Bracket with a few upsets to report. Here are the headlines:
Bad News for Nuisance Species: Watermilfoil, spiny waterflea, rock snot, Realtors, skunks and porcupines all went down to defeat.
Good News for Threatened Species: Bicknell’s thrush, timber rattlesnakes, and proposed APA boathouse regulations prevailed (though tender rattlesnake root, Prenanthes Boottii—correct spelling—proved no match for the heavier boots of Black Brook). » Continue Reading.

Bat Populations Plummet

In February 2006 a caver photographing hibernating bats in Howe Caverns near Albany noticed some bats with an unusual white substance on their muzzles. The following January New York Department of Environmental Conservation (DEC) biologists documented more bats with white noses, bats behaving erratically, and numbers of dead bats. Since then NY DEC biologists have been monitoring more than 30 winter bat “hibernacula” in New York’s caves and mines. Over the past three years 93% of the bats in the Northeast, afflicted with what is known as “white-nosed syndrome,” have died. According to the US Fish and Wildlife Service, more than a million bats have perished from New Hampshire to Virginia in the past four years! » Continue Reading.

An Invasives Barrier for the Champlain Canal

Asian carp are all over the news and will soon be all over Lake Michigan unless the Chicago canal that links the Mississippi and Great Lakes watersheds is re-engineered. It’s looking unlikely, but if the Obama administration decides to turn this dilemma into a major public works project—keeping a particularly nasty invasive species from upending the remnants of native Great Lakes fish life—there’s a canal on Lake Champlain that could use a lift too. » Continue Reading.

Lake George Counts itself a Zebra Mussel Survivor

In December 1999, researchers discovered that Lake George was not immune to Zebra mussels after all.

During an annual dive to retrieve litter from the lake bottom in Lake George Village, volunteers discovered what appeared to them to be the exotic mollusk that had already wreaked havoc in Lake Champlain and in nearby rivers, competing with native animal species for food and clogging water systems.

Diver Joe Zarzynski contacted the Darrin Fresh Water Institute, whose scientists confirmed that the brown and cream striped shell attached to a beer bottle was indeed a Zebra mussel. » Continue Reading.

North Country Hitchhikers: Getting Stuck on Seeds

There are lots of plants out there that really grab you…literally. We’ve all encountered at least one, probably more. With hooking barbs or puncturing spikes, they lam onto our shoes and socks, pant legs and shirt sleeves – and heaven help you should you be wearing a woven poncho when you have your run-in with them! Our dogs return from a romp in the field with seeds of all sorts clinging to their fur. Yep, late summer and fall are the time of year to get to know your seeds. » Continue Reading.

Another Invasive in the Adirondack Garden

“What have you got that the deer won’t like?” I asked the dude at the garden place. This was my favorite nursery, and over the years I spent hundreds of dollars there. I liked the people, I loved their display gardens, and their plant selection was terrific. Unfortunately, they included several invasive species in their stock and promoted them for garden plantings.

“The Japanese Barberry would be great – we have two colors, green and rose. The rose-colored one will look great next to your pale yellow house.” » Continue Reading.

The Silent War – Fighting Adirondack Invasives

Invasive species are everywhere: birds, bugs, fish, flowers, fungi. It seems that every time you turn around, a new invasive species has sprung up, each with its own inherent threat on the local ecosystem. What we don’t hear about, however, is often the solutions that are applied to address the problem.

Take for example the Japanese beetles in this photograph. What do you notice about them that is unusual? The white dots on their thoraxes. I pondered these, wondering if they were parasite eggs, warts or merely beauty marks. The number of dots differs on individual beetles, and some have none at all. Because of this variation, and the fact I had never seen them before, I was leaning towards parasites. » Continue Reading.

Wicked Plants – Even in the Adirondacks

Who could pass up a book titled Wicked Plants: The Weed That Killed Lincoln’s Mother and Other Botanical Atrocities? Certainly not I! Not only is the title attention-getting, but the book is a bilious acid green, the perfect color for poisonings!

I first heard about this book on the radio, and after about a month of waiting, I was able to borrow a copy from the library. After reading it, I had to get a copy for myself; no self-respecting naturalist’s arsenal of natural history reference books would be complete without it!

This tiny tome is chocked full of interesting information about some of nature’s most dangerous plants, many of which surprised me. For example, these days the news is smattered with dire warnings about giant hogweed and wild parsnip (members of the carrot family, yet capable of causing painful blisters and phototoxicity to those who brush up against them), but who knew that cashews could be problematic if not prepared correctly? Yes, cashews are related to poison ivy, poison sumac and poison oak. If eaten raw, or if they are contaminated with bits of the nut shells, the person consuming them can break out in a serious rash, which could be exacerbated if one is strongly allergic to urushiol, the irritating oil.

While many of the plants mentioned in this book by Amy Stewart come from lands far from the Adirondacks, there are a fair number that can be found within the Blue Line. Take, for example, elderberry. I remember collecting elderberry blossoms for my grandfather down along the railroad tracks that follow the Mohawk River. He used to make wine from the lacy white flowers. Well, it turns out that most of the plant’s parts (leaves, roots, stems, etc.) contain cyanide. This is especially true of the raw fruits. Cooked, the fruits are rendered more or less harmless, but when consumed raw they could send one to the hospital in a great deal of pain and discomfort.

How about cardinal flower? This brilliantly scarlet member of the genus Lobelia is found fairly commonly along waterways within the Park. As lovely as it is, the red color should be a warning. It contains poisons that are similar to nicotine, and if one were to eat it (although I don’t know why one would), one would likely suffer from tremors, nausea and vomiting, paralysis, and heart problems.

Not only does Ms. Stewart point out plants that are deadly, she includes those that are destructive (like purple loosestrife and kudzu), those that are offensive to the nose (purple trillium and skunk cabbage, among others), and those that actively cause problems (killer algae and gas plant).

I was so surprised at some of the nastiness that Mother Nature has in store for us that I was hesitant to burn the invasive honeysuckles we cut down last year. What if this aggressive non-native plant harbored some sort of chemical that was dangerous when set on fire? Nonetheless, burn it we did (the cut logs had started to sprout and had to be destroyed), and I can report that although I got a snoot full of smoke on several occasions, I have not suffered any ill effects.

Whether you are a plant aficionado, or a nature enthusiast in general, you will not want to pass up this delightful little book.

Fall Webworms: Our Invasive Insect Export

It almost seems too early, but there they were, web and all, clinging to my Royalty Crabapple: fall webworms (Hyphantria cunea).

For most folks, the sight of a webby mass clinging to the branches of a deciduous tree brings on thoughts of tent caterpillars. I learned early on in my youth that if you see this mass in the spring, it is tent caterpillars, but if it is late summer or fall, you are looking at fall webworm, an entirely different insect. If you’re still not sure, you can verify which insect it is be monitoring the movements of the caterpillars. Fall webworms stay within their webby nest all the time, eating and sleeping there. They do not leave until they are ready to pupate. Tent caterpillars, on the other hand, only use their webby nest for shelter at night and during inclement weather. When they get hungry, they must leave the nest to forage on nearby leaves. » Continue Reading.

Emerald Ash Borers and the Purple Triangles

Emerald Ash Borer Trap Hanging in Chestertown in June 2017 (photo courtesy Greg Dower)The purple triangles seen hanging on trees along Adirondack roads are traps designed to lure and capture emerald ash borers (Agrilus planipennis). Emerald ash borers are small (half-inch long) metallic green insects that are coming to us from Asia via Michigan and wreaking havoc on the ash trees of North America.

Recently I wrote a piece on the American elm and its decline thanks to an insect and a fungus. The same thing is happening today with the American beech. But the emerald ash borer (EAB) acts alone. This insect overwinters under the bark of the ash tree (black, green and white ash are all susceptible) and emerges as an adult in the spring. After mating, the female lays her eggs in the crevices of the bark and about ten days later they hatch. The larvae now begin their devastating work, tunneling under the bark, eating as they go. When winter comes, the larvae become dormant, waiting for spring to arrive, at which point they emerge as adults and the cycle begins again. » Continue Reading.

Hawthorn vs Hawthorn – Avoiding The Invasives

I took a few moments this morning to read the comments on past posts to the Almanack (thank you, all) and found a potentially distressing note on my deer-proofing post. I had mentioned that a good deer proof plant to include in your arsenal was hawthorn, and someone commented that we need to be careful about invasive hawthorns. Invasive hawthorns? I didn’t know there were such things, so I had to look it up.

Lo! and behold, the anonymous commenter was correct: there is an invasive hawthorn out there. It is Crataegus monogyna, the oneseed hawthorn, aka: English hawthorn. This plant has become quite the pest out in California, but it seems to have made inroads throughout the West as well as the East. According to the range map I saw, the middle of the US seems to be free of this invasive so far. » Continue Reading.

Lake Placid Closes One Boat Launch, Surveys Milfoil

On Lake Placid yesterday, efforts to contain recently discovered variable leaf milfoil moved forward on two fronts. As village officials prepared to close the village-owned launch on Victor Herbert Road—redirecting boat traffic to the NYSDEC launch next to the Lake Placid Marina—the Lake Placid Shore Owner’s Association released the first aerial photograph of the milfoil bed on Paradox Bay.


The photo, taken by the volunteer team of Lake Placid-based environmentalist and aviator Ed McNeil and Dr. Charles D. Canham, a forest ecologist with the Cary Institue of Ecosystem Studies, in Millbrook, was from a survey of the lake’s littoral regions in search of secondary establishments of the invasive weed. None were discovered. According to McNeil, the the favorable angle of the sun and the transparency of the lake water allowed them to survey to depths of about 12 feet. » Continue Reading.
