Marc DeWerth is on a mission.
From forests to river valleys, farms to private properties, he鈥檚 scouring the state in search of some of Ohio鈥檚 oldest living things: big trees.
鈥淭here are gems, monster-sized trees hidden everywhere you can think,鈥� he said. 鈥淚t鈥檚 just a matter of thinking outside the box to find them.鈥�
So far, he鈥檚 found some behemoths, from the 114-foot-tall eastern cottonwood in northeast Ohio to a sycamore with a 430-inch circumference in the southwest.
鈥淚 mean, the stem on that is just absolutely massive,鈥� DeWerth said. 鈥淭rees like sycamores, they love to be by water. And if they sit there for many years, they just get bigger and bigger and bigger.鈥�
To him, trees aren鈥檛 just a pastime, they鈥檙e a lifeline 鈥� literally releasing oxygen into the air, sheltering bugs and birds and standing tall for generations.
鈥淥ne large tree can outproduce 50 tiny trees,鈥� he said. 鈥淭hey鈥檙e beautiful. They鈥檙e big. They鈥檙e discussion pieces.鈥�
The start of the search
DeWerth describes himself as an avid outdoorsman.
鈥淚'm constantly hiking and searching Ohio's deep forests for just about any kind of subject matter possible,鈥� he said. 鈥淎nd it seems like I always stumble upon these trees.鈥�
He started taking pictures of them and posting his finds to personal social media pages. They quickly gained traction.
鈥淧eople were overwhelming me with questions about them,鈥� he said.
So DeWerth made separate and pages just for trees, called Big Trees Ohio.
鈥淔rom there, it just went bonkers,鈥� he remembered.
Years later, he now has tens of thousands of followers on both platforms, and he estimates that he鈥檚 documented over 1,500 big trees. Some of which, he said, the state had never recorded.
Teaching about trees
Many of the big trees DeWerth has found grow on private property. When he spots them, he鈥檚 quick to knock on owners鈥� doors. Most people he meets are excited to talk about their trees.
鈥淎 lot of times they don't know what kind of tree it is, so they want to learn more,鈥� DeWerth said. 鈥淎nd once you clean the area up and they realize what they have, then they become what I call 鈥榩roud big tree owners'. They go on to keep maintaining it, and I will give them advice on what they can do to keep the tree healthy.鈥�
Often, DeWerth will also report his finds to the Ohio Division of Forestry鈥檚 , a volunteer-led effort to measure and record the largest trees of every species in the state.
Four of the trees DeWerth has found in Ohio are current 鈥� the biggest trees of their species in the country. These trees don鈥檛 receive any special protection, but they do offer valuable insight, DeWerth said.
鈥淚t gives you an idea of what's growing in what areas of the state, which species are dominant, subdominant and codominant and what species are only growing in certain regions, maybe due to climate zones or soil quality.鈥�
All along the way, DeWerth shares his discoveries online, posting daily pictures of big trees and hoping his enthusiasm for them catches.
鈥淲hen you have something that makes you happy and smile,鈥� he said, 鈥渋t's going to make you want to plant more of them and continue propagating them.鈥�
That鈥檚 exactly what he wants: to ensure big trees are around for future generations to find too.
