One part of the urban forestry program is an ordinance which identifies Portland's Heritage Trees. Heritage Trees are "trees that - because of their age, size, type, historical association or horticultural value - are of special importance to the City". I don't remember how I first heard about the program, but it was several years ago, and I was happy to find that we lived just down the block from a Heritage Douglas fir. We've moved since then, and our nearest Heritage Tree now is a Shagbark hickory (Carya ovata). What's your closest Heritage Tree? Use this map to find out.
OPB's Oregon Field Guide recently did an interesting piece about Portland's Heritage Tree program.
Portland’s Heritage Tree program began in 1993 to recognize and preserve trees with special significance to the city... We follow the selection committee made up of citizens and botanical experts as they assess this year’s nominees, with special concentration on the Zahner family’s southern Catalpa tree.
So Portland has some pretty great trees, but what about the rest of Oregon? Turns out there's an state-wide version of Heritage Tree program as well.
You can read more about Oregon's Heritage Trees (and get that brochure Grant mentioned) at the Oregon Travel Information Council's website.
