5000-acre Forest Park is the crown jewel of Portland's parks system. It's an incredibly popular destination for walkers, joggers, cyclists, wildlife viewers, and more. Commissioner Fish has been working hard to balance these increasing recreation demands while improving the ecological health of the park.

This week, OPB's Oregon Field Guide explores the challenges and opportunities facing the park in "Forest Park: Portland's Backyard Gem."

The show airs this Thursday night at 8:30. We hope you'll tune in!
