The city of Portland is noted for its proximity to outstanding natural areas—Mt. Hood, the Columbia Gorge, Oregon's North Coast. But Portland is also a great place to live because of the abundance of natural areas within the city itself.

Why is Oaks Bottom such a treasure for Portland residents and what is being done to enhance its wildlife habitat?
