"Fabulous! I've been on many nature walks, but rarely are they this intelligent and entertaining."
– Emma Paske, birder & Dendro Lab member
New York City is a concrete jungle and an urban forest. To better connect with the latter, we lead 14 different walks to help you learn our most common trees. Knowing them will make you a more observant naturalist, a better birder, or an all-round happier person. It's easier than you think and we can help.
See you in the park!

Getting the most out of your tree walk
Meeting Time: Please arrive 10 minutes before your start time. Walks will begin promptly at 5 minutes after the hour and routes may vary, making it difficult to find the group after we set off.
Weather Policy: Walks are rain or shine, unless lightening or high winds are present. Check the forecast and please come prepared. Tickets for cancellations will be credited toward a future walk of your choice or refunded upon request.
Come to Learn: Pure enjoyment is our #1 goal, but you're encouraged to bring a notebook, pen, and camera-phone. You'll receive far more information than you'll be able to recall later without them.
Note: All workshops are limited to 15 participants to ensure the highest quality experience and in order to be the least obtrusive to other visitors in the park's natural areas.
November Event Schedule
Nov 1st, Saturday
morning, 10am – 12
Fall Foliage &
Phenology Tree Tour
Location: Central Park, NYC
West 77th St. entrance
It’s a magical time of year to live in the northeastern temperate forest. Come walk among the trees and discover why leaves change color in the fall and why are some years and some species more vibrant, while others remain green. We will also explore other aspects of the autumnal phenophase, which for many trees includes fruiting and for a few, even flowering.
Your Guide: Carey Russell
afternoon, 1 – 3pm
Conifers, Part 1:
The Pine Family
Location: Central Park, NYC
West 77th St. entrance
Make way for some needles and cones! This walk is dedicated to one of the three native conifer families in the U.S. and Canada, which includes more than just the pines alone. Trees covered: white pines (eastern white and Himalayan pine), yellow pines (pitch pine, Austrian pine), eastern hemlock, larch, Norway and Colorado blue spruce, cedar, and Douglas-fir.

Trees covered include: eastern juniper (aka eastern red cedar), bald-cypress, dawn redwood, arborvitae, false-cypress, yew...and ginkgos (which are neither conifer nor broadleaf tree!) The pine family (pines, spruces, firs, hemlock, etc) is covered in a separate walk, Conifers, Part 1.
Your local Dendro Lab Guiding Team
Carey Russell, founder and senior guide
In a nutshell: I have a boundless love for trees and science communication. I have a MS in forestry, am a Certified Interpretive Guide (NAI), master naturalist, licensed outdoor guide in New York State, and a member of the International Dendrology Society and the North American Association for Environmental Education. My greatest pleasure comes from helping others rediscover nature in their daily lives.
My day job: I'm a photographer and filmmaker. Projects have taken me to India, Mongolia, Myanmar, Guatemala, and Antarctica. I recently published a book about the summer camps I attended in my youth. Please visit my creative projects site at careyrussell.com.
Pro-tip: Within a week, repeat the route or your walk and share as much as you can with a friend. Nothing takes learning to the next level quite like teaching something to another.
