Leave the leaves – northwestern salamanders need these!
Northwestern salamanders are abundant west of the cascades. You may spot them under logs or among leaf litter, but the best time to see them is when they migrate to breeding ponds January to March. They migrate hundreds to thousands of feet, leaving the safety of their logs and leaves to cross lawns, streams, and even roads! When threatened, a northwestern salamander will arch its back and push its head towards the ground to release a white poison to coat its back.
Leaf litter provides shelter, food, moisture, and warmth for these salamanders. They can hide from predators amongst the leaves and use the leaves to hunt prey. Northwestern salamanders are carnivores, preying upon the insects, worms, spiders, and slugs that frequent leaf piles. The salamanders also need the moisture that builds up in the leaves and the insulated warmth of the leaf litter.
Northwestern salamanders aren’t the only wildlife that need leaf litter to survive! Ground nesting pollinators, small mammals, and other amphibians thrive in leaf litter.
You can support northwestern salamanders and other wildlife by leaving the leaves this fall. If you must rake the leaves, leave smaller leaf piles around the space. Even small piles host a variety of wildlife! Find more information on how to support wildlife where you live, work, and play by visiting https://wdfw.wa.gov/species-habitats/living/habitat-at-home
