With peak camping season upon us, now’s an ideal time to explore one of WNC’s more mysterious + secretive residents: the native marbled salamander. Though elusive, they’re out in droves right now — so naturally we had to chat with salamander savant + UNC Asheville biology professor Rebecca Hale to learn more about the unique value of these chubby amphibians and how best to coexist with them.
What makes salamanders so valuable?
Salamanders act like amphibious tillers, aerating the ground to help oxygen reach plant roots. This is also beneficial for the animals and insects creating habitat in compacted soil. “Bacteria + fungi need oxygen for decomposition,” says Rebecca, “so the deeper the oxygen can go, the better the decomposition and the better the soil’s health, and all the life in and around it.”
They also act as pest control, eating small animals like insects, spiders + worms. By eating insects that destroy leaves, salamanders also have a real impact on reducing the impact of climate change.
Fast facts
- WNC’s mountains are home to more species of salamanders than anywhere else in the world. In fact, we’ve been referred to as the salamander capital of the world.
- There are an estimated 500 species of salamanders.
- Salamanders have the greatest collective biomass in all of WNC.
- Unlike many salamanders, marbled salamanders aren’t poisonous.
How to coexist
Avoid the seemingly innocent act of stacking or flipping river rocks when outdoors, implores Rebecca, as this can disrupt and eliminate salamanders’ habitat. She also encourages folks to avoid venturing outdoors when it’s muddy, as our shoes can compress the ground + disturb habitats.
