Our Forest Service colleague Geoffrey Donovan has been studying the impacts of trees on property values in Portland. Catch a first glimpse of the results in Community Tree Connections, the newsletter of the Oregon Dept. of Forestry Urban and Community Forestry Program. "On average, trees add $7,020 to the price of a house in Portland, which is equivalent to increasing the size of the house by 106 square feet."
The Urban Forest Greenhouse Gas Reporting Protocol moves forward with the California Climate Action Registry! The Registry has made some changes to our final draft of the Protocol and released their version for a period of review and public comment. We hope you'll take the time to review it and share it widely. Comments are due August 4 and can be addressed to firstname.lastname@example.org. The California Registry will hold a public workshop on Tuesday, July 29 at 1 PM - 4 PM (PDT) at the Cal/EPA Headquarters in Sacramento to discuss the Urban Forest Project Reporting Protocol and answer questions.
Urban Forest Greenhouse Gas Reporting Protocol: We've completed the final draft of the Urban Forest Protocol and have presented it to the California Climate Action Registry for their review. They will hold a public comment period this summer and then will vote to adopt during their August board meeting. We'll provide the details of the public comment period when they become available.

San Francisco Bay Area State of the Urban Forest Final Report: We've just released our study of the urban tree canopy of the San Francisco Bay area. The report had three goals: (1) to describe the historic changes to the region's urban canopy cover and amount of impervious surface, (2) to quantify the value of ecosystem services the current forest provides, and (3) to estimate future benefits based on possible expansion of the urban forest. It's full of interesting information for Bay area residents and anyone who would like to know more about the benefits of trees. For a quick review, read our one-page summary.
Unraveling the Debate: Some of you may have been following recent controversies in the media regarding the role of trees in the fight against global climate change. Read our take on the subject in the fall issue of California Trees. "Trees and alternative energy sources
