We all know that trees provide all sorts of benefits to people, right? But different trees provide different benefits and trees will only provide those benefits if we can make sure they stay healthy.

In this episode, Stephen Elser (@stephen_elser) interviews Jenna Rindy (@msjerindy), a PhD student at Boston University, about her research urban tree research. She tells us about how two species of oak tree vary in how much soot they remove from the air, and why that's so important for human health. We then discuss how human-caused fragmentation of forests affects tree health, and how that in turn affects us. We wrap up with a brief conversation about some challenges that climate change brings to urban forests.

Jenna wrote a haiku about her research:

Trees help cities to breath
But cities can hurt trees too.
What is the real cost?
