The land side should ideally have a couple of holes drilled in the bottom of the tank to ensure good drainage. Put coarse sand or washed aquarium gravel in the bottom to a depth of about two inches. Top this with a piece of turf or clumps of moss. Some small potted terrestrial plants may be planted on this side. You will need a fitted lid for the tank.
Salamanders can climb, using body secretions for suction.
The lid is also a useful place on which the required lighting can be placed. Terrestrial sallies do require high humidity, so plants and moss will help achieve this, as will a dish of water. The evaporation will help maintain humidity levels. As with the vivaria, the terraria also requires a lid. Heating Salamanders from temperate climates will not need special heating as long as they can be kept at the same temperatures they would encounter in their native habitat.
