Do you like climbing trees? 

Do you like being outside? 

Maybe you should consider becoming an Arborist. 


An arborist is a tree doctor, and in this activity, you will get to meet an arborist and ask him any questions you have! 


First, let’s learn a little bit more about trees. 


You can learn more on this website.

Or, watch this video about trees.

Or, watch this video to learn about what would happen if we cut down all the trees.

Now that you know a little more about trees, it’s time to meet Alec Baxt, our very own arborist in Cobble Hill. Alec takes care of trees around Brooklyn and on Governors Island. 


Meet Alec the Arborist in Carroll Park (in front of the park house) on Saturday, May 22 anytime between 2-4pm. Ask him any tree-related question. Here are some of our questions: 

  • What’s the best tree for a tree fort? 

  • How old is the oldest tree in Cobble Hill? 

  • How do you trim very high trees? 


Where: Carroll Park,  in front of the Park House

When: Saturday, May 22 between 2-4pm 

Rain date will be Sunday, May 22 between 2-4pm. 

Turn It In

Post your question and Alec’s answer on Padlet. Feel free to add pictures of trees to explain!
