Forest fragmentation in Vermont

I wrote this column earlier this year. Afterwards, nothing changed. The bulldozers keep on churning.



The wildlife-unfriendly issue of “forest fragmentation” just went before the Vermont Senate in Montpelier in the form of legislation to stop it in the Green Mountain State.
Too bad, though, for the state’s natural heritage that in the end corporate powers won and the legislation was tabled.
But, the very fact that proposed legislation focused on the issue is remarkable. The Vermont Senate may have set a “Ripley’s Believe It Or Not” record as the first state legislative body anywhere in the U.S. to address the issue.
“A proposal to limit forest fragmentation was thwarted by developers who oppose using the state’s land and development laws as a tool to keep woodlands intact, according to the lead sponsor of the bill that was gutted on the Senate floor Wednesday,” the Web-based news magazine VTDigger reported March 19.
“There’s nothing ‘complicated’ about stopping forest fragmentation,” one Vermonter commented. “This is just another episode of legislators kow-towing to the corporate interests that make campaign contributions.”
State Sen. Peter Gailbraith wrote, “The Audubon Society points out that Vermont has the most diversity of bird species of any state in the continental U.S., and the reason is our large inter-connected forests. The (Gov. Peter Shumlin) administration has itself identified fragmentation as the number one threat to biological diversity in our forests, and yet neither the administration nor the legislature is willing to do anything to prevent it. This is a tragedy.”
Galbraith also noted that the legislature’s nod to “study” the issue is only cover. “A study is the legislature’s way of killing a proposal while pretending to the voters that it is concerned about the issue.”
The bill would have required development already undergoing the Act 250 review process to maintain forest integrity, VTdigger reported. “If development must alter forests, the developer could purchase a conservation offset at another site to balance the impact.”
Act 250, a state Website explains, is “Vermont’s development and control law, established in 1970. The law provides a public, quasi-judicial process for reviewing and managing the environmental, social and fiscal consequences of major subdivisions and development in Vermont through the issuance of land use permits.”
Converting large, continuous forests into smaller woodlots (islands) has many negative impacts, especially on bird species whose reproductive success plummets in fragmented landscapes.
The Cornell Lab of Ornithology: “Forest fragmentation occurs when large, continuous forests are divided into smaller blocks, either by roads, clearing for agriculture, urbanization, or other human development. Ornithologists suspect that fragmentation harms many woodland birds by increasing their susceptibility to predation and nest parasitism.
“Predators such as jays, crows, raccoons, and cats, as well as the parasitic Brown-headed Cowbird, typically are not abundant in extensive forests. But when a forest is fragmented, predators and cowbirds gain more access to the woodland. The importance of large areas of continuous forest for maintaining forest-interior bird species has been demonstrated in the eastern United States during the past 15 years.”
The chopping (literally) of forests into smaller blocks is a top cause behind population declines of many native North American birds. They include the state bird of Vermont, the Hermit Thrush.
“Forest fragmentation remains an important conservation issue for many species of wildlife, including the Hermit Thrush, which prefers large tracts of forests,” wrote ornithologist Douglas P. Kibbe in “The Second Atlas of Breeding Birds of Vermont.”
The rate at which fragmentation is occurring is substantial greater in Pennsylvania. I know there are some folks in Harrisburg who understand the threat to the commonwealth’s natural heritage. But I’d bet that none sit in the legislature or statehouse.

Roads and the future of wildlife

This is a fresh newspaper column from me




Almost from the moment in 1988 when my late wife and I moved to Conyngham from the Air Force base at Plattsburgh, N.Y., I began keeping track of roadkill – the native wildlife species I came across while hiking and fitness-walking on the many rural roads surrounding the borough in both Sugarloaf and Butler townships.
The list-keeping has continued ever since and also includes roadkills found in other states, both East and West. Most of the species I annotated in field notebooks (I’m now in my fourth volume) were, however, found on Pennsylvania roads. That’s simply a matter of having spent more time exploring, hiking, walking and cycling in Pennsylvania than elsewhere.
It takes very little to stir my memories of those journeys on foot. It happened again this week as I scanned through my photo library, coming across images of dead wildlife from those years.
There, see those eyes? I wonder what that Eastern Cottontail (that’s the official name for a creature most folks label a “rabbit”) would say if it had a chance? The photo, snapped with a first-generation digital camera on West County Road in Sugarloaf, shows the cottontail on the asphalt ribbon’s shoulder, its dark eyes staring upward, frozen in time.
Most roadkill, whether found on Butler Drive in Conyngham or on any other road, amounts to a carcass flattened almost to the point of making species identification difficult. But not this cottontail.
Even making a good guess at the roadkill data in Pennsylvania, or any other state, is hard-to-impossible as even keeping track of the dead of one species – the white-tailed deer – is tricky and time consumptive.
One thing for sure, though. Pennsylvania has to be the dead white-tailed deer champion throughout the species’ wide range. There are several factors at play in that estimation. From the ecological side is this: Pennsylvania has a lot of edge habitat; edge habitat favors habitat generalists, like the white-tail and raccoons, squirrels, opossums, skunks and more. And just like in other eastern states, Pennsylvania keeps on creating even more edge habitat (e.e., the zone between one habitat type (forest) and another (the shoulder of a road). Our society’s zeal for sprawl development and our reliance on the private automobile (the machine that made sprawl happen) mean even more edge habitat and more deer.
My field notebooks tell me this: I’ve now tallied the roadkill dead of 157 animal species, from bumblebees and green darners up to sapsuckers, screech owls, Canada goose, and on and on and on. My overall tally (and, again, most of those numbers were tallied in Pennsylvania) is, surely, quite conservative in scope.
If we were ever able to put together an entire team of naturalists to go out and, say, over a 24-hour period, keep track of every roadkill species found, the final tally would be much higher than what my own field notes reflect.
The solution?
Walk, not drive your car, when you can. Live in already established neighborhoods. Tell your borough council or township supers you do not like the idea of more sprawl development.
And tell them you want our community to be as friendly as it can be toward bicyclists and walkers – forms of transportation that keep practitioners slim, fight obesity, and burn calories, not fossil fuels.
And which save wildlife – our natural heritage.
Look carefully at the accompanying photo of an Eastern Cottontail: What do those eyes tell you?

Effort to avoid vote on fracking falters in Colo.

We keep on poking holes in Earth to (1) get natural gas and(2) make money. Meantime, wildlife habitat is irretrievably fragmented, destroyed, and otherwise kissed off. In the end, America's natural heritage continues slipping into "threatened and endangered" states. Read about what just transpired in Colorado right here.

Stopping forest fragmentation by legislation?

Roadkill victim in Nebraska: A mountain lion

More roads means more dead wildlife. And birds, too. And amphibians and reptiles, too. Read about the cougar that was struck and killed in northwestern Nebraska.

A good walk yields surprises



Parking, roads, sprawl housing and highways equal traffic congestion.

That’s what I see daily on one particular highway in Vermont.

And just as I used to do while walking along Route 93 in and near Conyngham, Pa., I look closely at each passing car to determine how many people are in it. My conservative estimate is this: Only one of every 99 motor vehicles that zips past me as I walk the shared walkway/bicycle path has more than one person – the driver – inside the cab of the hurtling 2,000-pound hunk of steel, plastic and glass.

That tells me this: There is no ride-sharing or carpooling to speak of. Vermonters, just like most Americans across the land, are true believers in the “freedom to pollute” philosophy I first heard about while a college student at Idaho State University in the early 970s.

(I write to air some personal thoughts, not pass on those of any organization).

After having my new passport photo taken at the town hall in early July (yes, Vermont has “towns;” Pennsylvania has one, Bloomsburg), I walked across the street to the Williston library to get a new library card. And it will let me borrow books from other local libraries, like the one in Essex Junction village to the north, which I actually live closer to and can walk to, not drive.

I could walk as well to the Williston library, but doing so would pose all sorts of safety hazards – all created by the absence of sidewalks or walkway.

When parking at a grocery store two miles from home, I always shake my head in wonderment at the home builder’s sign stuck into the turf across the road I just traveled, for that is a perfect example of what helps generate more vehicular traffic in the first place: Sprawl development.

It’s the same “highway-leads-to-sprawl-and-more-cars” situation I saw for years snaking across the Nescopeck Creek valley outside Conyngham.

Yes, I know everyone deserves a nice home. It’s American, after all. But yet I see, while walking, more than a few nice places for sale these days, both in Williston and in Essex Junction. It was much the same situation in the Hazleton area during my two decades there.

How about we try and get people into these existing houses before more natural land is chewed up for a new sprawl neighborhood and its attendant automobiles? Will there be yet another “meadows” development in Sugarloaf? It’s inevitable, I guess.

So, I offer some suggestions: Put walkways, bicycle paths and sidewalks at the top of the funding heap. And remember that spending less on roads means more for public health and environmental mitigation.

Don’t allow any more trees to be felled. Trees native to Pennsylvania (just as those native to northern New England) are carbon dioxide sinks and yield oxygen in the bargain.

The objective of our municipal planning staffs should be to give people the freedom to move about freely without the burden of enormous gasoline and automobile expenses. What could be more American than that?

P.S. Experts recommend at least 2½ hours of moderate activity (such as brisk walking, brisk cycling, or yard work) a week.  It's fine to walk in blocks of 10 minutes or more throughout your day and week. If you're worried about how brisk walking might affect your health, talk with your doctor before you start a walking program. Daily dog walks are also a great way to keep up your walking routine.

And walking helps you meet other folks. You can’t do that when behind the wheel of your car, truck or SUV.
Vermont, I grant, is a leader in alternative transportation choices, but widening highways or building new ones simply to relieve congestion does not work – regardless of the state.
