For years now, local transportation agencies have embraced trees as a key component in street and path design. In Portland, there has also been a strong connection between people who ride bikes and those who care about street trees. Now a national non-profit, the Alliance for Community Trees (based in Maryland) is hosting a webinar about how tree advocates all over the country can make the bike-tree connection.
In the Portland region, trees have been part of the transportation conversation for years. The Oregon Department of Transportation has planted hundreds of trees as part of an effort to create an urban "forest" along the I-205 bike path. In 2008, Portland City Council adopted the "Grey to Green" initiative which set us on the path to planting 83,000 trees in the city — 50,000 of them in the public right of way. The Portland Bureau of Transportation (PBOT) has made new street trees a big component of their neighborhood greenways program — offering free trees to residents along the low-stress, family-friendly bike routes.
