Dried oak leaves are often used in terrariums, especially for reptiles and amphibians. They help create a natural environment, while also providing a suitable habitat for certain species that like to hide or seek refuge under dead leaves.
 Dried oak leaves also have beneficial properties for reptiles, as they can release tannins into the surrounding moisture, which helps maintain a natural pH level and has a mild antiseptic effect. They are sometimes used for turtles, lizards, and amphibians to simulate natural conditions and create a microhabitat conducive to their well-being.
 Finally, dried oak leaves are an ecological alternative to other types of substrates and decorations in terrariums, contributing to a wilder and more aesthetic atmosphere.
