Finding New Ways To Avoid Adirondack Roadkill

RoadkillMany of us are familiar with the guilt of hitting an animal while driving. The way that its body weight seems to travel through the frame of the car is difficult to forget.

But the fact remains that we have places to be and even a few well-intentioned road signs cannot slow us down. In our ceaseless efforts to connect our world, we don’t always consider the ways that our road network has fragmented the animal habitats it paves over.

The unpleasant task of shoveling the battered carrion from our roadways falls to local highway departments. But what exactly happens to the bodies from there? I reached out to representatives from a few local county highway departments and it turns out their methods vary, but most are taken to landfills or compost bins. Scavengers remove many of these animals before road crews have a chance to clear the roads, a valuable but underappreciated ecosystem service provided by crows, ravens, foxes, and the like.

A study published in the New Zealand Journal of Zoology found that seasonal peaks in road kill for specific species was dependent upon breeding periods and dispersal. Deer and moose are particularly vulnerable to vehicle collisions during their fall mating seasons, according to a representative for the New York State Department of Environmental Conservation (DEC). Disseminating information on these predictable changes in animal behavior provides some aid, but the number of incidents remains troubling. This suggests that accommodating for animal behavior could be more effective than attempting to educate human drivers. » Continue Reading.

Porcupines And Their Need For Salt

Over the next several weeks, the buds on hardwood trees and shrubs will open and the forests will again be cloaked in green, providing our many herbivores with a welcome change in their diet. While many plant eaters are able to subsist on woody buds and cellulose laden layers of inner bark throughout winter, leafy matter provides far greater levels of nourishment. The porcupine, a common denizen of the deep Northwood’s forest, is among our region’s first order consumers to ingest greens when they emerge in spring.

In winter, the porcupine settles into a routine of eating only the bark and needles of a very few species of trees in the area around its den. The stomach and small intestine of this rodent contain strains of microorganisms that act on this ultra-high fiber material in order to derive the energy needed to remain alive in this climate. Yet the limited amount of nutrients, particularly nitrogen, in such plant tissues makes this type of food less than ideal for maintaining a healthy diet. Despite ingesting large volumes of woody matter each night in winter, the porcupine often loses weight continuously as this bleak season progresses. » Continue Reading.

New Analysis: Freshwater Lakes Getting Saltier

lake mononaNorth America’s freshwater lakes are getting saltier due to development and exposure to road salt. A study of 371 lakes published in the Proceedings of the National Academy of Sciences reports that many Midwestern and Northeastern lakes are experiencing increasing chloride trends, with some 44% of lakes sampled in these regions undergoing long-term salinization.

The study is the first large-scale analysis of chloride trends in freshwater lakes. It was conducted by a team of fifteen researchers as part of the Global Lake Ecological Observatory Network (GLEON) Fellowship Program, an initiative that seeks to train the next generation of freshwater scientists and practitioners. » Continue Reading.

Lake George Towns Embrace Road Salt Reduction Strategies *winter

lg highway garageLake shore towns could reduce their salt usage by half simply by applying a liquid solution to roads before a storm arrives, highway superintendents, contractors and town officials were told at a workshop in Lake George in December.

Using the salt and water solution, commonly known as brine, as well as more advanced plows, especially when combined with conservation-minded practices, could reduce the amount of salt spread on local roads and highways even further, perhaps by 75%, said Lake George Waterkeeper Chris Navitsky, whose organization co-sponsored the workshop. “The more we learn about the impacts of road salt on the Lake George watershed, the more motivated we are to achieve road salt reductions in the earliest possible time frame,” said Navitsky. » Continue Reading.

Road Salt Impacts Waterways, Soils and Infrastructure

Living in the Northeast we depend on clear roads during winter to maintain our way of life. Organizations, agencies and municipalities throughout upstate NY and VT understand that there is an impact to the environment from road salt application practices. We must find the balance that protects the environment and still allows for safe roads.

Road salt (sodium chloride) was first utilized within the U.S. on roads in NH in 1938. By 1941 a total of 5,000 tons of salt were applied to highways nationwide. Today, between 10-20 million tons of salt are applied annually. This increase in road salt application is having a negative impact on our waterways, soils, cars, and infrastructure. Lake Champlain alone has seen a 30% increase within the past 10 years in chloride levels and many bodies of water within the Adirondack Park have levels high enough to impact native aquatic organisms including fish populations. » Continue Reading.

Peter Bauer: In Lake George Election, The Lake Won

Photo by John Warren.The election last night in Lake George was a referendum on protecting the lake and the lake won. Last night, the team that was swept into office in 2011 on a platform of real change in town government built around protection of Lake George was handily re-elected.

Dennis Dickinson won as Supervisor and Marisa Muratori and Dan Hurley won for the Town Board. Dickinson and Muratori narrowly lost the Republican primary in September, but were elected on the Reform Party line. This is the second time that Muratori has been elected on a third party line. Hurley was elected as a Democrat. » Continue Reading.

Road Salt Use Wasteful, Damaging

TOS_SALT_BRINEAll of a sudden, sap season is here and winter’s on its way out. Chances are though, a few more snow or ice squalls are still to come. The next time you find yourself driving behind a big plow truck, take a look at what’s coming out of the spreader. What is used makes a difference for wildlife, especially as the snow melts. » Continue Reading.

Fund: Lake George Salt Levels Can Be Cut 40%

Snowplow (Lake George Mirror file photo)The salt in Lake George would decrease by 40% over a ten-year period if highway departments reduce its use now, by half, says Dr. Jeff Short, a science advisor to The Fund for Lake George.

“Any actions we take will be apparent almost immediately,” said Short.  “If we cap loading now and then dial down, the results will be clear. So the incentive for taking action is huge.”

The Fund for Lake George is crafting a strategy to achieve that goal, said Eric Siy, The Fund’s executive director. » Continue Reading.

Cutting Road Salt On Adirondack Roads

Plow-600x382Standing next to a small, unnamed stream near where it empties into Mountain Pond on a cool September day, scientist Dan Kelting reads a sensor he just dipped in the water to measure electrical conductivity, which is used to gauge road-salt concentrations.

Pure water is a poor conductor of electricity, but road salt, or sodium chloride, increases conductivity. Based on the conductivity reading (285 microsiemens per centimeter), Kelting calculates that the water contains 80 milligrams of chloride per liter. This means the stream contains roughly 160 times more chloride than a similar size stream a few miles away.

Why the difference? The stream near Mountain Pond, north of Paul Smith’s College, is downstream from Route 30, a state highway that is heavily salted in the winter. The other stream, which Kelting refers to as Smitty Brook, runs through the Forest Preserve and is upstream of roads. » Continue Reading.

Adirondack Road Salt Alternatives Sought

SnowplowA conference at Paul Smith’s College this week led to the formation of a working group that will look at alternatives to applying road-salt on local roads.

The all-volunteer group, which is still being finalized, will study the costs of alternative de-icers and their impact on roads, bridges, and water quality. It will also examine roads in the Adirondacks to see where sunlight could be used to assist with snow and ice removal. It will identify funding sources for further studies of groundwater contamination, salt toxicity, public education, and training of state and municipal employees.

The group is expected to include members of local and state highway departments, environmental groups, local elected officials, and scientists. » Continue Reading.
