THE DENDRO LAB
 
 
 

Yes, New York City is a concrete jungle, but it's also an urban forest. To help you connect with the latter, we lead 14 unique walks to help you learn our most common tree species. 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're here to help.

See you in the park!


 
 

"Fabulous! I've been on many nature walks, but rarely are they this intelligent and entertaining."

– Emma Paske, birder & Dendro Laber

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.

Your Local Dendro Lab, NYC Guiding Team

 

Carey Russell, founder and senior guide

In a nutshell: I have a boundless enthusiasm 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. 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.

 

Marc Leone, guide

In a nutshell: Birding, baseball, and dart throwing extraordaire.

My day job: Working to make the internet a safer and kinder place.

Pro-tip: One way or another, be it pressings, rubbings, or illustrations, start a leaf colletion!
