Despite the rain, we were out planting this #tree in the West Village with 8 more set to go in the ground in Red Hook before we close out this year!

Congratulations to our first cohort of Urban Forest Fellows - Jose, Mariya, and Julien! They helped us expand our programming, resulting in thousands of stewarded trees, as they trained 16 YUF Interns who helped us care for 399 trees we planted with our Trees For NYCHA project.

Outdoor learning is turning NYC students into urban environmental champions! Our youth programs have inspired young NY'ers for nearly 20 years, and empowered them to steward hundreds of trees in 2025! Support our mission—every donation helps! 🙌 Thank you! https://t.co/90vI4aywAD

This mixed-media art exhibit by Nina Browne, a woodworker turned urban naturalist, invites us inside the artist’s life and inside wood to reflect on our living relationships with trees and the Earth.

A #scarletoak, #Quercuscoccinea, showing how it got its common name in Bed-Stuy, Brooklyn. Great to see these as #streettrees - thank you @NYCParks!

What an amazing accomplishment! This fall, we worked with over 20 schools, 2000 students, and cared for 110 #trees with the help of students.

Did you explore the #urbanforest this weekend? If so, you likely noticed that some #trees don’t drop their leaves in the fall but keep most of them on the tree through the winter, like this #swampwhiteoak. This is called marcescence, and why some #tree species do it is unknown!

We're so grateful to our TreesNY educators & teachers at the schools we work with, who recognize the value of youth environmental education, and the students and future environmental leaders who help us steward hundreds of #trees each year. Thank you all so much for your support!

Woodpeckers love to drill virtually straight rows like the one displayed here on this #LittleleafLinden, into the bark of #trees to search for sap and insects trapped within the #tree as a food source. Enjoy our #urbanforest this weekend and see what other wonders you can find!

Enjoy the #urbanforest this weekend! #Ginkgotrees are a historic native of NY State although their modern native range stretches across Asia. Found as #streettrees in NYC, they feature a unique #whorledleafing arrangement, and in November, their #leaves are likely already yellow!

#Plantingtrees in the West Village is the perfect way to spend a fall day! Last week, we #planted four #streettrees! We were joined by #CitizenPruners, and they learned how a #streettree gets planted.

Enjoy the #urbanforest this weekend! #GreenAsh #Trees are one of the few w/#compoundleaves you can find in NYC. They are a known target of the #EmeraldAshBorer, a beetle that creates markings underneath the bark in the larval stage and leaves exit holes as it emerges as an adult.

Our #TreesforNYHCHA project has been a huge success! As we continue putting forth #treestewardship initiatives to maintain this historic investment, we are still prioritizing #wateringtrees to ensure they survive and thrive through ongoing dry weather conditions.

Congratulations to the volunteers who recently joined our cohort of #CitizenPruners, seen here #pruningtrees during their field outing in Brooklyn as part of their training. We are so grateful to them and the 300+ volunteers that signed up this year for the #CitizenPruner course!

Go outside and enjoy the #urbanforest this weekend! The #Sweetgumtree features star-shaped leaves and spiky, gumball-sized fruits. The #tree earned its name from its fragrantly sweet sap that was historically used as chewing gum. Crush a leaf to enjoy its aromatic scent!
