Vegetation Stripes in Somaliland

Abstract

The occurrence in the western part of the former Somaliland Protectorate of patterns of parallel stripes of vegetation separated by lanes of bare or nearly bare ground is described. The stripes and lanes are several miles long, from 50 to 200 yards (45 to 180 m) wide, and run in straight lines up and down the direction of steepest slope. They occur in Acacia bussei-Chrysopogon aucheri or Acacia tortilis-Andropogon cyrtocladus bush communities and in Chrysopogon aucheri grassland. The soils of the bare lanes are lighter textured and have a deeper topsoil than the adjoining vegetation stripe soils. Soluble salts are leached to a greater depth in the lanes. The vegetation patterns are thought to be due to the variation in texture of the soil parent material.
