Leaves are out, flowers are opening, and fruit is forming. Hope you are enjoying making observations! We'd especially love photos of tree flowers and pollen this season, so if you have good pictures, please post them. (Review the guidelines first, though!) Thanks :-)

Group Description

This group is for members of the Arnold Arboretum's Tree Spotters Citizen Science program to share photos of the trees we are observing, as well as photos of Tree Spotter events (e.g., Tree of the Month Gatherings). Each tree photo must be tagged as described in the Group Rules section below.

The Tree Spotters program is open to anyone, but you must be trained in order to participate. For more information, see

Group Rules

You must tag each photo of a specific tree with the Accession Number and the date on which the photo was taken, using the DD-MON-YYYY format (e.g., 03-DEC-2016).

We also encourage you to use the following optional tags, as appropriate: Your first and last name (e.g., "Suzanne Mrozak"), Route Name (e.g., "Beech Route"), Common name (e.g., "American beech"), Scientific name (e.g., "Fagus grandifolia"), and "Tree Spotter Event" for organized Tree Spotter activities (e.g., Training classes, Focus Tree Gatherings). Note that you will have less clutter in your tags if you enclose strings of words in quotes, as shown above. If you forget to do that, each individual word becomes a tag, which can be a little overwhelming.

if you have any questions regarding tags, please email us at
