Wildlife Architecture: Building A Beaver Lodge

Beaver_lodgeAll mammals that employ the use of a shelter in winter instinctively attempt to find a place completely hidden from the view of humans for their home, except for one. When the time comes in late summer or early autumn for establishing a protective enclosure for the coming season of cold, ice and snow, only the beaver places its residence in a spot that can be readily noticed by a person passing through the area.

When hiking, canoeing, biking or driving past a stretch of quiet water, you can often see a sizeable, cone-shaped mound of sticks packed with mud jutting well above the water’s surface. This is the temporary, winter residence of a family of beaver which provides these flat-tailed creatures with shelter from the cold, and protection against their few natural enemies. » Continue Reading.

Loon Quilt Raffle to Benefit Loon Conservation

Loon QuiltThe Biodiversity Research Institute’s (BRI) Adirondack Center for Loon Conservation will be holding its first-ever Loon Quilt Raffle. The hand-made quilt depicts a pair of loons raising two chicks on an Adirondack lake. The queen-sized quilt was created by Dr. Nina Schoch, Coordinator of BRI’s Adirondack Center for Loon Conservation, based on a McKenna Ryan design, and quilted by Susan Ochs of Saranac Lake.

“The proceeds from the loon quilt raffle will help support our loon research and outreach initiatives over the coming year. It was a lot of fun making this unusual quilt,” said Dr. Schoch, “and I hope the support it provides will enable us to continue to address numerous threats to Adirondack loons and the lakes and ponds where they live.” » Continue Reading.

Small Species: Critical to Ecosystem Health

Michael Klemens sampling for amphibians(1)Small species slithering unseen within the forest leaf litter, or croaking and peeping from the edge of wetlands rarely take center stage in either conservation or Adirondack land development discussions. 

In fact, they are often completely overlooked, but that is changing with the leading work of Dr. Michael Klemens. An internationally recognized biologist, herpetologist and scientist-advocate for conservation design, Dr. Klemens has been retained by Adirondack Wild to give much needed attention to frogs, salamanders, and reptiles – key to the base of our Adirondack forest ecosystem and food chain. » Continue Reading.

Adirondack Wildlife: The American Toad

toad cropThe damp weather pattern over the Adirondacks since mid-May, while being a challenge to some creatures, has been most favorable to many others. Among those forms of wildlife that benefit from a moist atmosphere and frequent bouts of rain are the numerous terrestrial amphibians that occur in shady locations across the region.

While the Adirondacks is home to over a dozen species of these moisture-loving entities, the largest and most frequently encountered is the American Toad, a chubby and slow moving animal that is among the most recognizable members of our wildlife community. » Continue Reading.

The Crayfish: An Adirondack Crustacean

CrayfishAdirondack waterways serve as home to a wealth of invertebrates that range in size from microscopic to those that are several inches in length. Among the giants of this complex and diverse group of organisms are the crayfish, which are larger, more robust and meaty than many vertebrate forms of life in our region.

Because of their size and abundance, crayfish are an important component of all fresh water environments; however these fierce-looking entities have not been as thoroughly researched and studied as have other creatures that reside in the same general surroundings. While the basics of their biology and natural history are known, much still remains to be learned regarding the individual species that populate the many bodies of water throughout the Adirondacks. » Continue Reading.

Adirondack Wildlife: The Four-Toed Salamander

four_toed_salamanderLet’s start out with a riddle: What animal has 16 toes and a tail that breaks off when grabbed by a predator? Not sure? Here’s another clue: It’s the smallest terrestrial vertebrate in our area. If you didn’t guess four-toed salamander, don’t feel bad—it’s probably also the least-known salamander in the North Country.

The four-toed salamander (Hemidactylium scutatum) holds a number of dubious distinctions. Besides its diminutive size (a typical adult may only reach 2-3 inches in length), it is also the only terrestrial salamander with four toes on all four feet. With the exception of the aquatic mudpuppy (which happens to be our largest salamander), all other salamanders have five toes on their hind feet. Four-toeds also have specialized breeding habitat requirements, which probably accounts for their limited distributions in our region. Combine that with their small size and cryptic behavior, and you have a recipe for an animal that very few people have ever heard of, let alone encountered. » Continue Reading.

The Dragonfly: Master of Flight

Slaty_Skimmer_on_flowerThe ability of a flying animal to move through the air varies greatly, with some creatures possessing an exceptional mastery of this skill. While many forms of life simply use their aerial capabilities to quickly and efficiently travel from one place to another, others have evolved extraordinary airborne talents. Bats, swallows and swifts are all well known for their highly maneuverable style of flight, allowing these hunters to pursue and capture bugs in the air. Yet, from an aerodynamic perspective, the most unique and complex flying creature in the Adirondacks is the dragonfly, which must be considered the true master of flight.

The dragonfly actually represents a group, or order, of insects known as Odonata, which encompasses many species of both dragonflies and damselflies. All of the individuals in this category have evolved a highly complex flight style produced by their two sets of long, slender and transparent wings. » Continue Reading.

Art and Nature: Returning To the Heron Nest

Heron on nest, 2013If you’ve been reading the Adirondack Almanack for a while, you may recall my emotional writing about the heron nest I found in the spring of 2012, and the three charming youngsters that were about half-grown when nature intervened and they became dinner for some predator like a large owl or a bald eagle. I was devastated as I’d been quietly visiting the nest site for weeks, observing and photographing the heron family. You can see a YouTube video of one of the parents feeding the three youngsters here.

I’m happy to say, the herons are back on the nest. Or more accurately, according to what I’ve read, a male heron, perhaps the same one, returned to this nest site, made sure the nest was in tip-top shape, and then courted a female (who may not be the same one as last year) and convinced her to join him for mating season. I trust those close friends who know where this pond is will keep it quiet and not disturb this nesting pair. » Continue Reading.

Adirondack Insects: Mayflies

DSCN1675As the water warms in streams, rivers and lakes, there is an explosion of invertebrate activity, when the hoards of aquatic bugs that pass much of the year on the bottom are stimulated by the favorable thermal conditions which allow them to continue with their life cycle. Among the insects preparing to leave the safety of some protective nook, or transition into a stage that no longer perfectly matches the surroundings, are the mayflies, an exceptionally prolific and ecologically significant group of aquatic organisms.

Mayflies form a category, or order, of insects known as Ephemeroptera, which literally translates into the short-lived insects. This label is somewhat a misnomer, as most mayflies have a life span of one full year. Nearly this entire period, however, is spent underwater, initially in the embryonic form of an egg and then as a naiad passing from one nymph stage into another as they consume and convert microscopic matter in the water into body tissue. » Continue Reading.

Some Beaver Dams I Have Known

BeaverDam WLate last week, I found myself gazing into the woods as we headed down the Northway, en route to the Crandall Library Folk Life Center for a pleasant evening of entertainment. It was partially a business trip, but after listening to Dan Berggren and friends sing, alternating with readings by Carol Gregson from her first book (Leaky Boots) and her new release (Wet Socks), it sure didn’t feel like business. A good time was had by all, as evidenced by a very appreciative crowd.

During the ride south from the Plattsburgh area, my partner, Jill, handled the driving, which allowed me to enjoy uninterrupted views of the scenery. Included were some roadside marshes with beaver dams and lodges, prompting a flood of memories tied to my history with beaver dams. » Continue Reading.

Shoreline Regs Are About Water Quality

WaterQuality-3The protection of water quality is of singular great importance for the Adirondack Park and Adirondack communities. In the coming decades, if we are able to maintain stable water quality trends, this will help Adirondack communities enormously, not only for protecting the area’s high quality of life, but economically too. Clean water will be our edge.

Clean water is going to be a commodity that becomes less plentiful in the future. Communities that provide good stewardship for their waters will be communities that have something special to offer in the coming years. » Continue Reading.

New Report: Lake Champlain Basin Flood Resilience

Lake Champlain FloodingThe Lake Champlain Basin Program (LCBP) has released a new report, Flood Resilience in the Lake Champlain Basin and Upper Richelieu River. The report presents results of an LCBP flood conference held in 2012 at the request of Vermont Governor Shumlin and Quebec’s (former) Premier Charest, following the spring 2011 flooding of Lake Champlain and the Richelieu River Valley. The report provides a review of the 2011 flooding impacts and includes specific recommendations to help inform flood resilience policies and management strategies to reduce the impact of major floods anticipated in the future. » Continue Reading.

Adirondack Amphibians: Spring Peepers

Silence still prevails along the shores of marshes clad in alders, willows, dogwoods and wild raisins, but this will change shortly. The warmth forecast for the coming week should be sufficient to finally melt any remaining patches of snow and ice still on the edge of open wetlands. Additionally, the appearance of the sun and a period of mild showers should help eliminate the remnants of frost in the upper parts of the soil.

As the ground loses its winter characteristics, the spring peeper is quick to awaken from its winter dormancy, crawl from its shallow, subterranean shelter along with countless numbers of fellow peepers, and travel to a nearby marshy setting. Once it arrives at the water’s edge, this amphibian loudly announces its presence and willingness to breed. » Continue Reading.

The Outside Story: Pussy Willow’s Time to Shine

pussy_willowLast fall, I went to a nearby wetland with a pair of clippers and cut twigs from one willow shrub after another. It wasn’t hard to tell the willows from the non-willows because willows are the only woody plants in this area whose buds are covered by a single bud scale.

These cute, pointy caps are very different from the overlapping scales that protect most buds through the winter. And the few woody plants with no protective scales are easily recognizable: their naked, embryonic leaves rely on a coating of woolliness to keep them from desiccating or freezing. » Continue Reading.

Commentary: We Should Protect Vulnerable Vernal Pools

This Spotted Salamander just crossed Ski Tow Road, Tupper Lake, en route to a vernal poolWander into a wood with your ears open in early spring  and you are likely to quizzically turn your head to try and locate an indistinct sound, far off but not too far off, remarkable but subtle, an undertone of  – castanets? That’s how we described the sound 29 years ago when as new homeowners we explored our forest and discovered the breeding quacks of the wood frog.

I learned by wandering that wood frogs bred in the hundreds, not just in that one forest pond (a vernal pool), but in several others hundreds of yards apart – but not in every pool, just in some. Twenty-nine years later, they continue to breed just in those same pools between March 15 (the earliest date I’ve recorded their sounds) and April 15 (the latest), depending on temperature. » Continue Reading.
