Crossings
Ben Goldfarb
Based on how many references to books I've read and loved, it seemed almost inevitable that I would find Crossings by Ben Goldfarb engaging and compelling. And with such fantastic phrases as "the ungulate panopticon," it was a delightful read as well, despite the often dire messages of the book.
Diving deep into road ecology, a discipline I'd never have imagined existed, provided a fascinating view into how humans have constructed boundaries that impact nearly all other animals on the planet. In the western world roads are so ubiquitous as to be nearly invisible, especially in reference to their impact on the natural world. Paved roads cover about one percent of the land area of the United States, but the ecological effect zone around them covers something closer to twenty. They divide the land into unnatural parcels, and it's the division that matters most.
What I didn't expect was how far the effect reaches past the roadbed itself. Traffic noise degrades habitat for animals that never go near the pavement—songbirds that can't hear each other over the drone, prey species that can't hear what's coming. The barrier directly harms, but the noise reaches much farther.
On a personal level, the chapter about forest roads was especially fascinating given how much time I've spent riding bikes on them. I had assumed (incorrectly) that because they weren't paved the impact would be somewhat lessened, but those negative impacts were just different.
I would have liked a section about the impact of roads on plants, but perhaps that's just because I recently read The Light Eaters by Zoë Schlanger, which I recommend strongly.
I would also recommend the following books as accompaniments to Crossings: An Immense World by Ed Yong to help provide context for the impact of road sounds, and Braiding Sweetgrass by Robin Wall Kimmerer, which Goldfarb cites directly, for its case that our obligation to land runs toward reciprocity rather than management.
