The foreground is created to mimic the ground, plants and other accessories to scenery. The ground, hills, rocks, and large trees are created with wood, wire mesh, and plaster. Smaller trees are either used in their entirety or replicated using casts. Grasses and shrubs can be preserved in solution or dried to then be added to the diorama. Ground debris, such as leaf litter, is collected on site and soaked in wallpaper paste for preservation and presentation in the diorama. Water is simulated using glass or plexiglass with ripples carved on the surface. For a diorama to be successful, the foreground and background must merge, so both artists have to work together.
