So, now that you have decided where your enclosure will be, and that the substrate and any plants within that area are safe, you will need to decide what materials to use to build your perimeters. There are many to choose from, some more permanent than others.
Take into account, before you decide, that tortoises are good climbers and do not like being able to see through their boundaries. If they can, they will become very frustrated as they will continually try to get beyond them.
Donít put any boundaries up against a tree, for example, as this will become a ladder for them to escape. Keep shrubs trimmed that are near boundary fencing.
The most popular materials are bricks, breeze blocks, wooden fencing and new railway sleepers (not used sleepers as they will have been coated with creosote which is very poisonous). Whatever you choose to use must be sturdy, safe, high enough that your tortoise cannot see over and impossible to climb up! A lip around the top of the perimeter boundary will help prevent any potential escapees. When you have finished your enclosure, always double-check for gaps: if you donít find them, your tortoise will.
