We need tree lovers -- both experts and nonexperts -- for an urban forest research project!  

Here's how it will work:

  • We'll send you a list of 10-20 trees in the neighborhood of your choice.
  • You'll go out within the next few weeks and measure a few aspects of the tree and its surroundings, such as its trunk size, type, presence of overhead wires, etc. (details to follow). If you can snap a picture, that would be great, but it's optional.
  • You'll return to your computer and either enter the trees into a special page on the Urban Forest Map or into an online spreadsheet (depending on which group you are assigned to).
  • We'll analyze the data with our partners at the U.S. Forest Service, and publish a report on the use of amateur and professional  tree lovers to gather data about trees, a comparison of that data to data based on aerial photos, and differences in data collection for trees of different species and sizes.  This knowledge will lead to improvements in planning, research and policy-making related to urban forests.

Out measuring trees

If you're worried that you don't have the necessary skills, don't be! We'll give you the tools you need, including the Urban Tree Key, a video about how to measure the trunk, and more. And we're here to answer any questions.

Interested? Thanks! Just drop me, Kelaine, a line at This e-mail address is being protected from spambots. You need JavaScript enabled to view it  before October 27 and I'll send you a few questions about your tree knowledge and a list of neighborhoods to choose from!

We are proud to announce that the San Francisco Urban Forest Map has won an award! The California Urban Forest Council has recognized the Map as The Outstanding Urban Forest Project of the Year for 2010. We are grateful for the honor and grateful to all of you who helped make it happen. We'll keep up the good work together!

We've had a great outpouring of responses and a lot of interest in the Map. Thank you everyone who has stopped by to explore San Francisco's urban forest. A number of you sent me questions using our Contact page, but didn't leave your email addresses so I could respond. I thought I would tackle a few of your questions here because others may be wondering the same things (new questions at the top):

I live in Toronto and am close to a variety of urban living groups. We also have a LOT of trees. Is there now, or in the future, a model to license this platform to other municipalities? Is there a way we could share costs, etc.

If you're interested in bringing the Urban Forest Map to Toronto, there are two routes forward: (1) The underlying software is open source and will shortly be available to anyone who wishes to make use of it. (2) Unfortunately, our grant is about to run out, but for projects with funding, our team can also be available to help. One little glitch to an international expansion relates to the eco impact values that are calculated for each tree. These are estimated using a U.S.-specific model created by the US Forest Service. There has been some talk recently of expanding the models to other countries and I would be happy to discuss more with anyone who is interested.

I don't see any of the Mayor's Trees for Tomorrow Trees that have been planted in the last 5 years.  That's a lot of missing trees.

Right now the trees on the Map are only from the databases of the Bureau of Urban Forestry and Friends of the Urban Forest. And of course any that have been added by tree lovers since yesterday. We reached out to many city agencies asking for their data and have had great support from BUF and FUF. We hope now that other agencies have seen the Urban Forest Map they will want to contribute.

For some reason, I can't seem to sign up. I keeping getting an oops.

In cases like these, please leave your email address so I can ask you a few questions. If you really don't want to, give us a few more details. What were you trying to use for a user name? When in the process did you get the oops? How many times did you try? Since we have just launched our site to the public there will be a few bugs along the way and more details will really help us figure out what is causing them.

Hi! I believe that the tree in front of my condo is a Princeton Sentry Ginkgo. I do not see this scientific type as an option for ginkgos in the drop-down menu. Would you mind adding it?

I'll be adding new species in the next week or two as requested, but in the mean time, feel free to add your tree as a ginkgo of the regular sort.

Add "has been cut down" to tree status field.

One of the choices under "Actions" is "Tree has been removed."

More as they come in...

Some of you have been wondering why most of the trees appear on top of the houses, as in the image below.

Most of the data that we have seeded (pun intended) the Urban Forest Map with comes from the San Francisco Bureau of Urban Forestry and Friends of the Urban Forest. Both groups keep track of their trees based on the street address, not the exact latitude and longitude of the tree to several decimal places. In order for us to get them on the map, we had to geocode them, which is a method of translating addresses into lat/long. The geocoder's default is to place things in the middle of the parcel.

So one of the most helpful things we can do as Urban Forest Mappers is help move the trees to the right place. Any tree on top of a house belongs out on the sidewalk. (We know this because the data sources only include street trees.) So log in and use the satellite imagery to help us shift the trees to their proper spots! I took care of the one at the bottom:

Welcome tree lovers--new and old! Some of you reading this have been following us for a while and others might just have found us today. Either way, we are glad to have you here on our big day to celebrate!

We celebrated the launch with a press conference this morning. Benton, a local fifth-grader was the highlight, demonstrating how easy the Map is to use.

We hope you'll log in and "log" a tree...on the Map too! And drop us a line if you have any feedback, questions, or ideas. We would love to hear them!
