Wait… “tree hunting?”…. What’s that all about you ask? Well, as a naturalist at Fernbank Museum I have many myriad interests in nature and one of those happens to be trees. Many people get images of dinosaurs in their heads when they think about Fernbank (rightly so!), but as the only natural history museum to arise from an old growth forest, we’re so much more than just dinosaurs! In the late 19th century, the Harrison family purchased the property that we now call Fernbank Forest. Their daughter Emily loved to explore the forest and grew up to be a teacher. It’s because of the work of Ms. Emily that Fernbank Forest was protected as a “school in the woods” for future generations. We now have 67 acres that are open to both the public and school groups. One of my most enjoyable duties as the Environmental Education Programs Manager here at Fernbank is leading students through Fernbank Forest and teaching them about the natural history of a Piedmont forest. I also get to work with student and volunteer “citizen scientists” through the museum’s UrbanWatch program to collect data in the forest and elsewhere across metro-Atlanta. This is where “tree hunting” comes in!
From when the leaves drop in the fall until when new growth appears in spring is the perfect time to “hunt” trees. By hunt, I mean searching for giant trees in Fernbank Forest and other areas around metro-Atlanta. Along with the staff at Trees Atlanta and the help of community volunteers (“citizen scientists”) I’m working to update the Champion Tree List for Atlanta. So what is a champion tree and why do we only hunt them in the winter? I’m glad you asked.
An Atlanta champion tree is one that has the highest tree score of that species in the city. The score is calculated through a point system based on its height, diameter (at 4.5’ above the ground), and crown spread. With these three numbers in hand trees can be given a specific score that can be compared to other individuals of that species. The tree with the highest number is the “Champion Tree.” The picture below is of the champion Tulip Poplar in Atlanta.
The reason we “hunt” trees in the winter is because when the leaves are down, trees are easiest to measure. Plus the snakes are inactive, poison ivy has lost its leaves, the mosquitoes are gone, and it’s not so darn hot and humid!
On a recent outing to Fernbank Forest I was able to measure a few Loblolly Pines (Pinus teada) and Tulip Poplars (Liriodendron tulipifera) while searching for new champion trees. The heights for the pines approached 135 feet! Some of the Tulip Poplars were nearly 5 feet in diameter! It’s like a treasure hunt without knowing exactly what the treasure is or where it will be found. Each outing in the forest teaches me something new. As I compile more data I can share this information with the public, students, families, and other scientists and educators. The more people we can get excited about trees, the more they will understand the importance of trees in our ecosystems (especially the biodiversity of old growth forests). Sadly, no champion trees were to be found on this last outing, but more data was collected to compare these trees to others throughout the city and this winter’s tree hunting season has officially begun!
***Update*** On a recent New Year’s Day outing with members of the Eastern Native Tree Society in Fernbank Forest we measured the tallest known White Oak’s (Quercus alba) in the state- up to 141 feet tall! These even surpass those in the Blue Ridge/Appalachian region!
Do you know of a champion tree in your back yard or local green space? If you have a tree you think could be a contender or if you have any other tree questions, please contact me at firstname.lastname@example.org or Robby Astrove at email@example.com.

The pumpkin splits open, and the fresh scent of pumpkin fills the air as several excited staff members and volunteers begin to scoop the pulpy gooey mess from the inside. After much squishiness and a few laughs, the pumpkins are finally prepared for Bugs, Bats & Bones Day—Fernbank’s annual Halloween event for families.
I’m happy I didn’t have to carve all the pumpkins (that will be used to decorate the Museum during the event) myself. My secret? I’m really not a good carver, but I love all the fun designs staff come up.
I can always tell when Bugs, Bats & Bones Day is getting close. The air gets a little crisper outside, the kids go back to school, and I find myself eyeing every Halloween catalogue and display that crosses my path. I’m drawn to all things skeleton, bat, insect, and of course, pumpkin.
“Would that make a neat game? How can I sneak some education into Plinko? How much fake spider web does one need so the insects will get stuck on a 20 foot web?” These are my dilemmas. My office shelves are piled high with bat craft supplies, plastic insects, and various candy and treats.
This has to be one of my favorite events of the year. Watching Museum guests come through the door with wide smiles dressed in costumes is plenty reward for all of the planning. We’ve seen dinosaurs, lady bugs, princesses, fire fighters and a very convincing lobster. I think one of my favorite moments was watching a 1-year-old ballerina in a pink tutu hug “Rantula,” our human sized tarantula costumed character. She looked so utterly delighted with herself that I think we might have a future entomologist on our hands. You know, only if she studies insects after ballet practice.
I love watching the kid’s eyes go wide as they explore animal x-rays, touch live insects, and try to toss a ring around a real pumpkin stem. Wait we’re learning?? This seems like so much fun!
For now I’ll munch on my pumpkin seeds, smile at the cat ears sitting on the corner of my desk and wait for next October, when I can share all of Fernbank’s Halloween fun.
Just don’t tell anyone I can’t carve a pumpkin very well.
