Transnational networks of oil rush under our feet every day. Millions of barrels. Does the presence of pipelines affect activity above ground?
I'm writing an article about pipeline construction in my state, and I've been interested in that very question. Can pipelines can affect local wildlife in the long-term? Other than at large pumping stations, it shouldn't have a huge impact (unless that oil or gas surfaces, of course). But maybe so.
In order to inspect their lines, companies clear their right-of-way of brush. This is great for general pipeline safety (although in some wetland-type areas — like in the picture above — plants grow so fast they quickly cover the area back up), but it ends up fragmenting habitat and increasing the matrix, which certain species really, really don't like. My ecology professor just taught us how
ovenbirds won't build nests near the forest edge, for instance. Now, does the 50-foot right-of-way like the one shone above really make a difference for wildlife abundance? The ovenbird would say yes. Does the ovenbird get a say?
In Vancouver, wildlife managers are faced with the question,
"Caribou, wolves or development?"
