The present invention incorporates rocks that are different sizes, shapes, and rock types which are arranged to produce an environment with a relatively high surface area, and such that numerous microhabitats are incorporated in the form of shelters, cracks, crevices, and holes. Also incorporated is variation in slope angle and aspect in the rocks that slope. On some or all of the rock surfaces is topsoil which is of different depths, below which can be mineral soil which is variable in physical and/or chemical condition. |
