There is so much about the everyday things in our lives that we don’t understand. When we see a tree, we have no idea what lives inside that tree’s trunk. Recent studies by scientists have found that inside a tree trunk there are entire communities of bacteria. A single mature tree hosts about one trillion bacteria, with different communities living in various layers.
What is especially remarkable is that some of the bacteria living deep inside a tree trunk are anaerobic, meaning they don’t need oxygen and produce methane. The outer layers of wood may absorb some of the methane, but more research is needed on that. The study’s lead author said that the inside of a tree trunk is more like a wetland, where anaerobic bacteria and methane producers thrive in low-oxygen environments.
Poets like Robert Frost and Joyce Kilmer have written famous poems about trees. While we admire the beauty of a tree and enjoy its leaves and their fall colors when they lose chlorophyll and turn vibrant, we often don’t think about what it takes to create them. In a desert, humans seek an oasis where conditions permit trees to grow. Most of the time, we take trees for granted and never consider what’s inside a tree trunk.
Genesis 1:12 tells us that God formed trees (the Hebrew word “ets”) as a special creation, separate from grasses or gymnosperms. That simple statement hides how complex it really is to make a tree trunk. As Romans 1:12 states, “We can know there is a God through the things He has made,” and the trees we see in our yard or garden demonstrate how much intelligence is needed to create a simple piece of wood.
