Forest Friends Website Gets an Update!


We’ve updated our Forest Friends sign-up map! The new version still shows the green trees available for care and yellow trees that are already being looked after. Search for your address and click on a green tree near you to get started. When you select an available tree, details such as the tree species and closest address will automatically appear in the Forest Friends form. If it’s a tree you’d like to care for, simply scroll down to enter your contact information and submit your form.


If you already signed up to care for a tree on our old website, you do not need to sign up again.



Every Forest Friend helps maintain a healthy, resilient urban forest! Thank you for supporting our City’s trees. Access our new Forest Friends map here.

Many trees in East Cambridge are available to be cared for by a Forest Friend!

 

Cambridge’s Urban Forest Master Plan Gets a 5-Year Update!


Public Works is excited to share that the City’s 5-year update to the Urban Forest Master Plan (UFMP) is now underway! Released in 2019, the UFMP is a comprehensive study of the past, present, and future of Cambridge’s tree canopy. It established goals and priorities for City staff, residents, businesses, and other stakeholders to maintain and grow a healthy, resilient urban forest.


The UFMP emphasizes equity, resilience, and shared responsibility, recognizing that everyone plays a role in supporting our trees. The City is once again partnering with the local landscape architecture firm Reed Hilderbrand and their team to lead this important update.


The 5-year update will assess progress since 2019, evaluate existing strategies, and recommend new or refined approaches to achieve our canopy goals. The process includes three phases—Analysis and Evaluation, Recommendations, and Documentation—and is expected to conclude in Spring 2026.



🌳 Interested in learning more? Join us for the first public meeting on Thursday, November 20 from 6-8pm at the CRLS main cafeteria at 459 Broadway to hear from the team and share your input! 

Get a Tree Planted on your Property!


The City of Cambridge's Department of Public Works (DPW) and the non-profit Green Cambridge invite you to be a crucial partner in growing our city's tree canopy. You can receive a tree to be planted on your property in Spring 2026 by the Canopy Crew!

 

What is Canopy Crew?

Canopy Crew is Green Cambridge’s 8-month paid urban forestry internship for Cambridge high school students. On Saturdays during the fall and spring, the crew goes out to properties across Cambridge and plants trees! Your yard could be one of these properties…

 

Why Your Yard Matters

Did you know that approximately 80% of Cambridge’s tree canopy is on private residential land? That's why your participation is essential!


This fall, Canopy Crew is planting 50 trees on private properties across Cambridge. Join the 150 residents who have already received a tree on their property and sign up to receive a tree in Spring 2026.

 

How to Get Your Tree

Whether you live in an apartment, condo, or house, if you have space on your grounds, you qualify!


The tree is planted and provided at no cost. To sustain this vital youth employment and tree planting program, we rely on community support: we ask for a voluntary, sliding-scale donation.


The process is simple:


  1. Request: Fill out the Tree Recipient Interest Form online at greencambridge.org/canopycrew. You will also find the list of trees we offer at this link.
  2. Site Visit: Crew staff will contact you in February to visit your property and finalize your site and tree selection.
  3. Plant: The Crew will plant the tree on a Saturday in the spring—all we ask is that you commit to watering and caring for it afterward!


“This organization is fantastic. The staff coordination and student planting made this project very enjoyable to be a part of. Many residents of this building have expressed their appreciation for all the efforts and look forward to a new landscape next year and beyond.” - Anne Jeka, JFK Apartments.

 

Teens: Join the Crew



“There’s such a strong community around it, and we are doing really important work. Before Canopy Crew, I didn’t think I would be interested in it, but then I did it, and I was like, ‘this is awesome.’” - Dante Randall, 2nd year Canopy Crew member, senior at CRLS.


Do you know a high schooler interested in a paid internship opportunity to plant trees, and develop hands-on and professional development skills in the environmental field? Applications for the Fall 2026 term opens on August 15th, 2026, and can be found at greencambridge.org/canopycrew.

Danehy Park’s Miyawaki Forest Update

Planted in September 2021, Danehy Park is home to Cambridge’s first Miyawaki Forest.

Recently, 15 sumac trees were removed from the forest, chipped, and the chips were spread in the forest. 20 mid-canopy trees were planted to fill in the gaps left by the sumac removal.


The forest was initially overplanted with sumac, and drought conditions allowed the sumac to thrive and outcompete other trees in the forest. To ensure proper forest succession and the establishment of climax shade trees, the sumacs needed to be removed.


This work had been postponed for several growing seasons in hopes that climax species would establish themselves on the forest floor, but through investigation, no seedlings had established themselves.



As the first Miyawaki Forest in the Northeast, there has been a learning curve; these lessons have been applied to the two subsequent forests installed in the City at Greene-Rose Heritage Park and the Peabody School.

Species Highlight: (Ginkgo biloba)

The award for the oldest tree species in the world goes to Ginkgo biloba, or the maidenhair tree. The ginkgo may also win the less-than-coveted award for smelliest fruit! Native to eastern Asia, ginkgos are known for their tolerance of pollution, poor soils, salt, and drought, beautiful foliage, and the fruit that falls from female trees. Ginkgos are dioecious, meaning it has separate male and female trees. Most of the ginkgos you’ll see around Cambridge are male. This is to avoid the annual smelly fruit drop from the female trees this time of year. Both male and female trees turn bright yellow in the fall and tend to drop their leaves almost all at once. Are there any ginkgo trees near you? Check out our tree species map to find some!

Forest Foe: Spotted Lanternfly (SLF)

You may recall that SLF was our Forest Foe for September 2025, so why are we featuring it again? Unfortunately, Cambridge was recently added to the list of many Massachusetts municipalities with confirmed SLF infestations. SLF is an invasive insect pest that has the potential to harm the agricultural industry and make it unpleasant to be outside in residential areas with large infestations. Massachusetts Department of Agricultural Resources (MDAR) closely monitors SLF and many other pests. They request that residents report any sightings of SLF. You can report sightings here: https://massnrc.org/pests/slfreport.aspx


More information on SLF is available from MDAR: https://www.mass.gov/spotted-lanternfly


This time of year, the adults and egg masses are visible. 

Upcoming Event: UFMP 5-Year Update – First Public Meeting 11/20

Join us on Thursday, November 20 from 6-8pm at the CRLS Main Cafeteria to learn about the Cambridge Urban Forest Master Plan 5-Year Update! Thanks to years of effort, Cambridge reached a major milestone in 2024: 30% of the City is now shaded by tree canopy! Join us to learn what helped us reach this milestone, share your experiences from the past five years, and help shape priorities for the years ahead!

Stumped! Urban Forestry Treevia


Learn a fun fact about urban forestry in Cambridge! 

Ginkgo trees have existed as a species, virtually unchanged, for how many years?

The trivia answer will be revealed in next month’s newsletter! 


Last month's question was " Which one of these leaves is not like the other? All these leaves are from a species of maple except one!?” and the answer was "E". A is a Red maple, B is a Silver maple, C is a Norway maple, D is a Sugar maple, E is an American sycamore (Platanus occidentalis), and F is a Sycamore maple. Did you get it right? 

Become a Cambridge Urban Forest Friend

We need your help to maintain a healthy, vibrant urban forest! Any Cambridge resident willing to regularly water the tree and provide some general care for the tree is welcome to become a Cambridge Urban Forest Friend.
