Uber-urban South Philadelphia might seem an unlikely place to find the next generation of naturalists, environmentalists and outdoor aficionados. But over the past four years, Adam Forbes, founder and director of the Philadelphia-based nonprofit Discovery Pathways, has done exactly that. After early career stops working with migrants, secondary school students and English language learners, Forbes

On an April morning, Nick Macelko was scouring the Assunpink Creek in Lawrence Township, New Jersey. It was a successful search. He found an acuminate crayfish (Cambarus acuminatus) on the creek bottom. “You can tell because he has that rostrum [part of the head that projects forward] that doesn’t have little spines on it. Cool.”

I parked my bike at nine in the morning on a heat-dome summer day and walked down the path into the University of Pennsylvania’s James G. Kaskey Memorial Park (better known as the BioPond).

Ever since Elizabeth Luce began training to become a yoga teacher, she wanted to teach classes outside. Now, every Tuesday evening, she leads a class right on the Delaware riverfront. “The best part about being in this location is it’s so active,” says Luce. “Everyone is out. If they’re not here doing yoga, they’re out

Lately, as I’ve walked through the city, I’ve found myself crisscrossing from one side of the street to the other based on the angle of the sun and how much shade the street trees offer. We’ve had a hot, humid stretch here in July, recalling the fierce heat wave in June. It did occur to

The concrete jungle isn’t for everyone, or welcoming to anyone, really. Especially in the summer, a landscape of asphalt, concrete, metal and glass doesn’t meet all of our needs. Nor do the indoor spaces — all stale air and artificial lighting — where we spend most of our sleeping and waking hours. But being outside

On an unseasonably cool Saturday during one of this spring’s stretches of wet weather, Yazmine Acosta, a 14-year-old from South Philadelphia, greeted visitors at a lakeside dock at Franklin Delano Roosevelt Park, just across Broad Street from the Wells Fargo Center. Her slender arms outstretched, she demonstrated how to swoop a paddle’s ends in and
