  Nonuniform spatial distributions of vegetation in scarce environments consist
of either gaps, bands often called tiger bush or patches that can be either
self-organized or spatially localized in space. When the level of aridity is
increased, the uniform vegetation cover develops localized regions of lower
biomass. These spatial structures are generically called vegetation gaps. They
are embedded in a uniform vegetation cover. The spatial distribution of
vegetation gaps can be either periodic or randomly distributed. We investigate
the combined influence of the facilitative and the competitive nonlocal
interactions between plants, and the role of crow/root allometry, on the
formation of gapped vegetation patterns. We characterize first the formation of
the periodic distribution of gaps by drawing their bifurcation diagram. We then
characterize localized and aperiodic distributions of vegetation gaps in terms
of their snaking bifurcation diagram.
