Ryan Bradley, writing for the New York Times:
Soon, thanks to a series of city- and state-sponsored greenway projects, the woods in the highlands that spill down to the Hudson will be interconnected, and a path will run along the river from the northernmost point of Manhattan down to the Battery — a great route for a bike ride or run, and a new, complete byway for the wild things coming down from the north. A fisher, a sort of weasel that preys on rodents, was seen in the Bronx last summer. That was unusual, but there could be more, moving farther south, as the paths into the city ease.
Interesting to think of NYC as a new type of habitat for animals, changing over time.
Also, I had no idea that earthworms are not native to North America!
