Willow Oak Leaf Litter — Temperate Leaves for Dart Frog Vivariums & Isopod Enclosures Description: Willow Oak leaves (Quercus phellos) from pesticide- and herbicide-free locations, fully desiccated. These leaves are most often between 2–5 inches long and brown/bronze in color when fully dried. Why keepers love Willow Oak leaf litter: Natural hides & stress relief — Inverts, amphibians, and small reptiles burrow under and hide among the leaves to feel secure Egg-laying sites — Dart frogs and many invertebrates naturally deposit eggs on and between leaf litter Humidity control — Holds and slowly releases moisture to help stabilize humidity swings Microfauna fuel — Feeds your cleanup crew (springtails, isopods) with constant food and shelter Mimics the wild — Recreates the deep leaf litter layer found in natural dart frog and invertebrate habitats for more naturalistic behavior Quick decomposition — Thinner than most commercially available leaf litter, decays quickly in a vivarium for fast nutrient cycling Spectacular & popular — Very popular for both vivariums and isopod enclosures Sizing: Most leaves are between 2–5 inches long. Best for: dart frog vivariums, tropical bioactive enclosures, isopod cultures, salamander terrariums, and rainforest-style naturalistic builds. Note: Only dried, brown leaves will be shipped.
