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?

Plant a tree: Here's why

All the way back to my days as a college student in the early 1970s, I pondered Americans’ love affair with the lawn – the greenest, purest, most dandelion-free turf that money (and lots of chemicals) could produce. Earning my tuition by mowing turf farms (a k a city parks) for the city of Pocatello, Idaho, just helped solidify my mental picture of it all.

In two-plus years of living in an on-base house on Robins Air Force Base, Ga., 1980-82) I finally formulated a more pleasing-to-the-eye scene: Urban trees as places liked by fellow creatures of Earth. In the case of that residential duplex, the Georgia wildlife the live oak tree attracted was enough to generate page after page of notes in an early field notebook that still has a prominent place in my home library.

Field naturalists are big note takers, recording a lot more than just the day’s high and low temperatures, but also signs of Wild Nature like the first day of swelling buds, the first early-spring appearance outside its winter burrow of the local woodchuck, and new signs of the spread of kudzu, the non-native vine that ate the South.

By planting trees native to our region of the continent (and the list of plants native to Pennsylvania alone is exhaustive), the homeowner can take pride in accomplishing many objectives.

Trees in the home yard do these things and a whole lot more:

- Trees release oxygen and absorb carbon dioxide to freshen the air.

- They trap dust and dirt, and remove pollution particles from the air.

- Trees increase property values. (Read a Wall Street Journal article about this at http://online.wsj.com/news/articles/SB10001424052702303722604579113230353966564)

- They provide shade in the summer, protection from wind in the winter.

- Trees give us leaves to make the best compost.

- Trees provide habitat for birds.

-        Trees make your neighborhood a more beautiful place.

-        Trees whose spring flowers show off for humans also offer food to native pollinators.

-        Neighborhoods and homes that are barren are known to have a greater incidence of violence in and out of the home than their greener counterparts. Trees and landscaping help reduce the level of fear.

The organization Tree People (treepeople.org) notes on its Web site: “Average temperatures in Los Angeles have risen 6 degrees F in the last 50 years as tree coverage has declined and the number of heat-absorbing roads and buildings has increased.
“Trees cool the city by up to 10 degrees, by shading our homes and streets, breaking up urban ‘heat islands’ and releasing water vapor into the air through their leaves.”
Most importantly in this age of Earth’s changing climate, trees do this: “Global warming is the result of excess greenhouse gases, created by burning fossil fuels and destroying tropical rainforests. Heat from the sun, reflected back from the earth, is trapped in this thickening layer of gases, causing global temperatures to rise.
“Carbon dioxide (CO2) is a major greenhouse gas. Trees absorb CO2, removing and storing the carbon while releasing the oxygen back into the air. In one year, an acre of mature trees absorbs the amount of CO2 produced when you drive your car 26,000 miles.”

So this spring, let’s plant a tree, or, better yet, a whole bunch of trees. You can learn about Pennsylvania’s native trees from the state Department of Conservation and Natural Resources at www.dcnr.state.pa.us/cs/groups/public/documents/document/dcnr_003489.pdf
