When there is no directional resource flow across the landscape, spatial patterns may still appear in various regular and irregular forms along the rainfall gradient, including, in particular, hexagonal gap patterns at relatively high rainfall rates, stripe patterns at intermediate rates, and hexagonal spot patterns at low rates.
Spatial patterns may arise on the landscape even when there is no directional resource flow, and these can take various forms as you progress along the rainfall gradient. For instance, hexagonal gaps are typical at higher rainfall levels, stripes emerge at intermediate levels, and hexagonal spots occur at lower rainfall rates.
