Dryland ecosystems commonly exhibit periodic bands of vegetation, thought to form due to competition between individual plants for heterogeneously distributed water. In this paper, we develop a Fourier method for locally identifying the pattern wavenumber and orientation, and apply it to aerial images from a region of vegetation patterning near Fort Stockton, TX, USA. We find that the local pattern wavelength and orientation are typically coherent, but exhibit both rapid and gradual variation… 

Topics from this paper

A topographic mechanism for arcing of dryland vegetation bands
The water transport in the Klausmeier model of water–biomass interactions is modified to qualitatively capture the influence of terrain curvature on the vegetation patterns, and it is shown that whether bands grow on ridges, valleys or both depends on the precipitation level.
The effect of landform variation on vegetation patterning and related sediment dynamics
Semi‐arid ecosystems are often spatially self‐organized in typical patterns of vegetation bands with high plant cover interspersed with bare soil areas, also known as ‘tiger bush’. In modelling
A morphometric analysis of vegetation patterns in dryland ecosystems
Vegetation in dryland ecosystems often forms remarkable spatial patterns. These range from regular bands of vegetation alternating with bare ground, to vegetated spots and labyrinths, to regular gaps

The conditions under which colonisation leads to patterning on sloping ground are investigated, showing that the slope also has an important effect on colonisation, since the uphill and downhill edges of an isolated vegetation patch have different dynamics.
Effects of precipitation intermittency on vegetation patterns in semi-arid landscapes
Results show that decay-type processes associated with a low frequency of precipitation pulses inhibit the onset of patterns and that under intermittent rainfall regimes, a spatially uniform solution is sustained at lower total precipitation volumes than under continuous rainfall, if plant species are unable to efficiently use low soil moisture levels.
Conservation of pattern as a tool for inference on spatial snapshots in ecological data
This work describes a new method for rigorous quantitative estimation of biological parameters from a single spatial snapshot of sessile communities, and formulates a synthetic likelihood through consideration of the expected change in the correlation structure of the spatial pattern.
Dynamics and resilience of vegetation bands in the Horn of Africa
Photographs taken in the 1950s over the Horn of Africa together with present-day satellite imagery are brought together to assess vegetation change over six decades, suggesting that band widths respond to human impacts on time scales relevant for remote monitoring.
Secondary seed dispersal in the Klausmeier model of vegetation for sloped semi-arid environments
Abstract The effects of secondary seed dispersal on the dynamics of banded vegetation are investigated in the framework of a generalized version of one of the easiest tools for the description of
Signatures of human impact on self-organized vegetation in the Horn of Africa
This study characterize vegetation change in areas of the Horn of Africa where imagery taken in the early 1950s is available and finds that substantial change is associated with steep increases in human activity, which is infer primarily through the extent of road and dirt track development.
Long-distance seed dispersal affects the resilience of banded vegetation patterns in semi-deserts.
It is shown that long-distance seed dispersal permits the formation of patterns with a very slow (possibly undetectable) migration speed, and even stationary patterns which could explain the inconsistencies in the empirical data.


Microtopography alters self‐organized vegetation patterns in water‐limited ecosystems
[1] In terrestrial systems limited by water availability the spatial distribution of vegetation can self-organize into a mosaic of vegetated patches and bare soil. Spatially extensive competition for
Role of biomass spread in vegetation pattern formation within arid ecosystems
[1] The spatial organization of biomass resulting from plant-water feedbacks in arid ecosystems, “patterned vegetation,” provides a macroscopic signal of nonlinear plant-water interactions and
Spatial decoupling of facilitation and competition at the origin of gapped vegetation patterns.
This study contributes to the growing awareness that combined facilitative and competitive plant interactions can induce landscape-scale patterns and shape the two-way feedback loops between environment and vegetation.
A Putative Mechanism for Bog Patterning
This work reports on regular “maze patterns” on flat ground, consisting of bands densely vegetated by vascular plants in a more sparsely vegetated matrix of nonvascular plant communities, and proposes that the patterns are self‐organized and originate from a nutrient accumulation mechanism.
Environmental modulation of self‐organized periodic vegetation patterns in Sudan
Spatially periodic vegetation patterns in arid to semi-arid regions have inspired numerous mechanistic models in the last decade. All embody a common principle of self-organization and make
Periodic versus scale-free patterns in dryland vegetation
Using a spatially explicit mathematical model for vegetation dynamics in water-limited systems, a general mechanism for global competition is unraveled: fast spatial distribution of the water resource relative to processes that exploit or absorb it.
Vegetation patterns along a rainfall gradient
A continuum model for vegetation patterns in water limited systems is presented. The model involves two variables, the vegetation biomass density and the soil water density, and takes into account
Determinants and dynamics of banded vegetation pattern migration in arid climates
Dense vegetation bands aligned to contour levels and alternating at regular intervals with relatively barren interbands have been reported at the margins of all tropical deserts. Since their
Periodic spotted patterns in semi-arid vegetation explained by a propagation-inhibition model
Summary 1  Vegetation cover regularly punctuated by spots of bare soil is a frequent feature of certain semi-arid African landscapes, which are also characterized by banded vegetation patterns
Soil and water components of banded vegetation patterns
Abstract Banded landscapes are comprised of alternating bands of vegetation and bare ground aligned along the contours in arid and semi-arid regions (50–750 mm rainfall), on very gentle and uniform
