Many of us have a common path to commute from each day. Part of our normal routines headed both towards and back home from our place of daily work. Along my own commute I drive along this one particular highway that cuts in to the middle of some local conservation land. It’s a nice area with a lot of deciduous trees on either side of the highway and I have seen many species like Deer, Hawk and Fox on several occasions.
Some years back a project to widen the road began as a part of Massachusetts “Big Dig” project and the state began to open up the highway infrastructure in and around the city of Boston. For along time this had not impacted the commute in my area away from the city until finally they decided to work on the highways further north of Boston and then my normal predictable commute suddenly changed dramatically. That small little highway near conservation land was becoming larger and the work took off at a feverish pace for a couple of years or more. It took a long time for things to settle back down but in time, it eventually did. Although the daily roar of heavy equipment had stopped one legacy of the construction work remained, the “Jersey Barrier”. For those of you who don’t know what a Jersey barrier actually is; they are those approx 3 foot tall cement walls made of snap together sections along the highways and even secondary roadways. They are made by pouring concrete into a re bar filled mold and have become all the rage in the construction world because they can be poured “as needed”. So widespread is there use as a highway traffic barrier that there hasn’t been much thought about their ecological impact. Imagine being a Mouse, Skunk, Porcupine, Opossum etc and being on the wrong side of a 3ft high smooth surface that you absolutely can not cross.
What about a turtle trying to reach a pond? It is not a small unimportant consideration; it is becoming a very big deal. Once they were installed the forest on either side of the road was totally separated for smaller wildlife since between the north and south bound lanes were endless miles of tightly connected barriers, each tied together neatly in a long and seamless string stretching far beyond the actual conservation land and across countless towns. That habitat has been “fractionalized” into two separate non connected realms each only half of what its original size was. There are places that have water on one side in the form of a marsh and forest on the other. The problem is that often individual towns conservation commissions miss the point since they simply see this as part of the highway department and are not necessarily thinking about the “connect-ability” of protected conservation land along the highway and rather just the single parcels themselves.
One of the most important things to consider when protecting wildlife is undoubtedly the preservation of habitat and lots of it. It seems simple enough at first thought; I mean what can be so difficult about remembering to leave some forest and wetlands aside so that our wild neighbors have a place to live? The problem comes down to more of a “big picture” scenario. By that I mean most towns and municipalities make jurisdictional laws specific for their own region, and list of conservation parcels. This does not mean they consider the connection points between parcels especially when they intersect other towns or jurisdictions. Wildlife on the other hand doesn’t really care about what we humans call a town, state or nations border. They are living with something we humans often idealize and rarely actually come to know and fully understand ourselves, called “Freedom”.
They will roam wherever they need to based on food availability, the search for a mate, curiosity about a new territory etc.
They don’t worry about taxes or town councils or even passports for that matter. They live a truly “free” lifestyle and do their best to live around and with, all of us. That is, until we create a physical barrier preventing them from moving across from one side of a habitat to another. Just imagine in an urban environment, there are many roads with many Jersey Barriers.
That means we can literally create “boxes” of island habitats where nothing small and flightless can get in or out from. Keep in mind “nothing will dig under a Jersey Barrier in the middle of the asphalt highway”. Just imagine if you were a small mammal and during the night attempt to cross the road to get to your drinking water, you could be in very big trouble. Wandering miles to find a place to cross trapped up against the Jersey Barrier and traffic. Too many times I have witnessed first hand turtles, opossum, skunks etc trapped up against a miles long barrier with traffic whizzing by on one side and the cement wall trapping them on the other. That being said there is a simple solution after all; why not create gaps at every few hundred feet?
It can be done and is in some case like in the image below where a simple gap has been left for wildlife.
What is ironic is that image is actually from the “Department of Transportation” Highway Commission website and even comes with caption about the gap allowing wildlife to cross. Before any traffic engineers tell me that they need to connect to provide the safety benefit allow me to point out that I have also seen a few cases where there was gaps connected by a steel plate but leaving an obvious opening. I don’t know if that was made for wildlife or not but I assure you it works for their benefit. That simple act doesn’t come with a big price tag in fact it probably costs the same as not having them since you will save money buy needing slightly less Jersey Barriers to begin with but then buy the scrap steel connection braces (made from scraps of steel “Guard Rail” Material 2 ft or 3 ft long). A net cost of close to zero. It’s simple, it’s easy, it’s cheap and it “works”.
You can help me spread the word on this one. If you like what you read in this article and live in a region where Jersey barriers are common without a gap for wildlife to cross please call or write to your local highway Department. Let me know what response you get by sending me an email at firstname.lastname@example.org. Working together we can make a difference and it’s about time we proved it. This simple and common sense consideration and action “will” positively help the lives of wildlife thanks to your own assistance within your community.
