How A Warm Winter Impacts Local Wildlife

20160104_tdpt_decDuring a mild winter in our northern forests, there are those of us who cheer our lower heating bills and those who scan the forecast, hoping for cold and snow. In a classic El Niño year like this one, when we often get unseasonably mild weather well into February, there are winners and losers in the natural world, too.

El Niño refers to a natural warming of Pacific waters. This phenomenon occurs every three to seven years, when prevailing trade winds, which drive the direction and force of ocean currents, slow down. As a result, cold water from the depths doesn’t get mixed with surface water, the ocean’s surface temperature rises, and global weather patterns can be altered. This year’s strong El Niño is being complemented by a low pressure system in the far north – called the Arctic oscillation – that’s keeping polar air trapped around the North Pole. » Continue Reading.

Snakes and Toads Provide Garden Pest Control

TOS_Toad_houseEncountering a snake in the garden causes many people to shriek or even panic. Yet snakes and another often unloved creature, the American toad, are among the most effective forms of pest control.

If you tolerate these herpetological visitors – or better yet, encourage their presence – you’ll be less likely to share your garden with ravenous bugs, or bottles of pesticide. » Continue Reading.

Climate Change is Altering Nature’s Clock

Salamander-Stager-600x383Scientist Curt Stager walks along the edge of the woods, his flashlight shining into the shallow water of a leafy, roadside pool on a dark night in Paul Smiths. It’s late April, and he’s out looking for spotted salamanders, wood frogs, and spring peepers that have migrated to shallow vernal pools to breed. After poking around for a minute, he lets out an excited shout: “There’s a salamander! There he is! He’s early!”

In the water is a dark, four-inch-long creature with bright yellow spots. In the same pool not far away, wood frogs float on the surface. In another week, pools like this will be a filled with breeding frogs and salamanders, which will leave behind egg sacks that hatch into larvae.

Spotted salamanders spend most of the year underground, so seeing them is rare except during these annual breeding migrations. Their journeys are triggered by the first rains of spring. » Continue Reading.

Some (Wildlife) Gluttons I Have Known

bass-shinertail-mouthThe recent annual Nathan’s Hot-Dog Eating Contest (really, it’s a sport?) reminded me of a few gluttons from my past – of the wildlife variety. The term is used loosely here to include some ambitious and/or instinctive eaters encountered during a lifetime of hiking and a lot of fishing in my younger days. Had cameras been pocket gadgets back then like they are today, some great illustrations would be accompanying this piece. At least a few would be of bullfrogs. » Continue Reading.

Vernal Pools: Hatch, Grow and Get Out

Vernal_poolsThree things happened this week: bluebirds and tree swallows returned, my road was graded, and the red maple buds popped. It’s time to search for vernal pools.

Vernal pools are small areas of wetland that form in the spring and dry up during the summer. Water collects in saucer-shaped depressions that have an impermeable layer of soil, leaves, or debris. Snowmelt and spring rains fill these puddles. Without an inlet to replenish the supply, summer’s sun and heat eventually evaporate the water, though a dense forest canopy helps delay the inevitable drying up. Some vernal pools may refill after a heavy rain, but the main characteristic is their temporary nature. » Continue Reading.

Adirondack Painted Turtles In Spring

April24 089After a long slumber buried deep in the protective mud beneath Adirondack lakes, the painted turtle is awake. Chrysemys picta, the eastern painted turtle, is common to many of our ponds, lakes and wetlands, preferring areas with abundant aquatic plants, ample spots for sunbathing, and sunny places with sand for nests.

Painted turtles are named for their intricate shell pattern and very distinct yellow stripes on their heads. Reaching an average length of 5 to 6 inches, they can live for more than 40 years. Being omnivorous, they feed on insects, crustaceans, fish, plants and any other food (plant or animal) they can find. Like snapping turtles, painted turtles can live in a wide range of habitats. » Continue Reading.

How Wildlife Are Affected By Intense Cold

February 15 2015 Extreme ColdIntense cold is hard on all forms of wildlife, however, some of nature’s creatures are better adapted to deal with this type of adversity than others. Those animals whose geographic range extends well northward into Canada and Alaska have evolved various strategies to cope with prolonged bouts of sub-arctic weather and are quite capable of surviving the unrelenting cold that the Adirondacks has experienced this winter.

Conversely, some components of the Park’s fauna are on the northern fringe of their range and are better suited for functioning in a temperate region, such as southern New York and the mid-Atlantic States. These creatures are probably not faring well this season. » Continue Reading.

How Do Toads Avoid Croaking in Winter?

TOS_ToadOne warm fall day, while standing outside a lodge I manage, I noticed movement inside one of the window wells around the basement. Realizing that something noteworthy was about to happen, I ran inside to alert our guests.

Together we all crouched to watch the methodical shaking of the earth below us. Slowly the ground moved a little to the left, then to the right, then there was a pause, then left again, right again. Eventually something reached the surface. I reached my hand out and gently touched the rough, bumpy, and very well camouflaged back of an American toad. It continued to emerge, fully exposing its body. The guests and I started pondering all sorts of questions about toads and their habits, but the biggest question of all was: where do toads go in the winter? » Continue Reading.

Adirondack Salamanders: The Red-Spotted Newt

800px-Notophthalmus_viridescensPCCA20040816-3983AEarly autumn is the time fog frequently shrouds valleys in the morning, and a heavy dew regularly coats unprotected surfaces for several hours after sunrise. As the atmosphere begins to cool with the change in seasons, moist conditions often develop at night and can continue well after dawn. This is ideal for our various terrestrial amphibians, which require damp surroundings for their survival. Among the members of these moisture sensitive vertebrates is the red-spotted newt, a unique form of salamander that goes on the move as the foliage changes color. » Continue Reading.

Clams That Live In The Woods

TOS_clamsClambakes, fried clams, clam diggers, clam shacks ― we usually associate clams with the ocean. You may have also seen freshwater clams in rivers and lakes. But did you know there are clams that live in the woods?

In our region, there are several species of fingernail clam that inhabit vernal pools, the temporary woodland pools where frogs and salamanders lay their eggs in the spring. As temperatures warm and melting snow and rain fill depressions in the forest floor, these small clams, only the size and shape of a child’s fingernail, become active. » Continue Reading.

Adirondack Wildlife: Emerging From Dormancy

vernal pool at Huntington Wildlife ForestThe unseasonably cool and overcast weather pattern that has prevailed over the Adirondacks for the past several months has impacted many forms of wildlife, especially the cold-blooded creatures that are early to awaken from their winter dormancy. Among the organisms that return to an active state as soon as the surroundings thaw are two common and highly vocal amphibians that spend winter embedded in the upper layer of soil, or beneath a pile of rotting, organic debris on the forest floor.

Within a few days of the frost melting from the ground around them, both the wood frog and spring peeper experience biochemical changes throughout their body that reactivate the tissues and organs that became dormant for winter. As soon as their muscles are functioning again, these small vertebrates pull themselves from the covering that engulfed them since last autumn and begin their journey to the vernal pools and shallow woody wetlands that serve as their breeding grounds. » Continue Reading.

Arctic Cold And The Frost Line

frost line depth map New YorkWinter seems to have come early to the Adirondacks, as below zero temperatures and periodic bouts of measureable snowfall have been a part of our weather pattern since the last few weeks of November. The arctic air that has regularly swept across the region has made a sizeable dent in everyone’s wood pile, placed a strain on car batteries and forced many to wear Christmas sweaters on a daily basis.

The intense cold has also pushed the frost line down in numerous spots, which greatly impacts the existence of those creatures that attempt to survive this season by burrowing into the soil. It is difficult to determine how deep the frost line has advanced, as this critical feature of the winter environment varies greatly from one spot to another. » Continue Reading.

Adirondack Amphibians: The Tadpoles of Winter

tadpolesFall is in full swing: foggy mornings, cold rains, and falling leaves. Time to talk about…tadpoles!? That’s right, while we may be accustomed to discussing tadpoles in spring and summer, they’re still around and they’re gearing up for winter.

Imagine your local pond. Under a slate gray autumn sky, the pond is mostly quiet. Only an occasional peep (called the “fall echo”) escapes from the reeds, where previously an amphibian chorus declared its presence. Yet despite the chill and silence, frog life continues. Most of the summer’s broods hopped onto land at least a month ago. Others will hibernate in the coming months as polliwogs.

So how do tadpoles “decide” when to change into frogs? And why do some of them stay in tadpole form all winter? » Continue Reading.
