A Rediscovery of the Elusive Wood Frog: A 20-Year Surprise
Written on
Chapter 1: The Unexpected Encounter
Recently, I made an astonishing discovery: a frog species not documented in my area for over two decades. Current research and maps suggest it shouldn’t be present, yet there it was.
As an avid nature enthusiast, frogs are my favorite wildlife, and while I’m not a specialist, I’ve become quite familiar with the various species in my locality. Upon first glance, I noticed something peculiar about this frog, specifically its striking dark red eye mask. Typically, such vibrant colors can indicate toxicity, which made me cautious; however, I later learned that these frogs are not harmful to humans, though it's still wise to keep pets away.
I encountered a wood frog, an intriguing creature known for its remarkable adaptations. These frogs have a unique ability to survive harsh winters by storing glucose in their bodies, which acts like antifreeze, allowing them to endure freezing temperatures.
The wood frog can exhibit a range of colors, including tan, brown, and even shades of red or pink. What truly captivated me was the distinctive dark red mask on its face. My initial reaction was one of alarm—“Poison!? Avoid this creature!”—a feeling that seems out of place in the American Midwest.
I also noticed its more elongated facial structure compared to the rounder frogs I usually see around here. As a passionate frog admirer (a self-proclaimed “amateur frog scientist”), I was intrigued by this pointy-faced frog. It was evident that this wasn’t one of the common local species, such as green tree frogs or gray tree frogs—my favorite being the Cope's gray tree frog.
I also recalled the rare, hefty American bullfrog, which I only spotted once during a run. Mistaking it for a baby skunk due to its size, it leaped dramatically away before I could react. This exciting encounter left me eager to learn more about the wood frog!
Curious about how frogs survive in frigid climates, I discovered that the wood frog employs an extraordinary hibernation technique. These frogs can endure freezing conditions by allowing up to 65% of their body to freeze. They achieve this with cryoprotectants—natural substances that prevent freezing. The wood frog’s liver converts glycogen into glucose, which not only inhibits freezing but also combats dehydration and cellular damage. As temperatures drop, their liver and heart store extra glucose, ensuring that vital organs thaw first as temperatures rise again.
Unlike many frogs that hibernate in cold water without freezing, the wood frog’s unique strategy is quite remarkable. I feel fortunate to have encountered one of these cool little creatures!
From my research, it appears that the wood frog hasn’t been spotted in my area for approximately 20 years. However, the data available dates back to 2001, so it could be even longer. It’s possible that I may have stumbled upon a frog that hasn’t been seen in my county for four decades. If anyone has contradicting information, I’d love to know!
Although the wood frog isn’t classified as endangered, habitat fragmentation has significantly affected their populations. They are particularly vulnerable to the dangers posed by roads, not only due to habitat loss but also because road salt contaminates their wetlands, potentially harming their tadpoles.
Seeing one of these frogs is a promising sign, and I hope to encounter more in the future! This year has been fantastic for frog sightings; I’ve even observed countless baby frogs on certain days. Frogs hold a special place in my heart, and each sighting brings a smile to my face.
I owe my love for frogs to my fourth-grade teacher, Mrs. D., who instilled in me a passion for both frogs and writing. She once predicted that she would read my published work one day. While I have plenty of book ideas in mind, I believe a piece about frogs serves as a fitting tribute to her influence.
Mrs. D.’s classroom was a haven for animal lovers, adorned with frog statues, toys, and stuffed animals, creating a paradise for a kid like me. Her enthusiasm was infectious, and here I am years later, writing about the fascinating frog I discovered.
Have you spotted any interesting frogs lately? I would love to hear your stories about any animals that bring you joy!

Thank you for taking the time to read my reflections!
