Pattern in a High-Level Juncus Squarrosus Community

Abstract

The structure of a Festuca ovina - Juncus squarrosus association is examined and a series of mosaic patches is described. The mosaic patches are visually indistinguishable, consisting of areas where the density, vigor, and pattern of J. squarrosus varies, expressing the different times of colonization. The mosaic patches are probably maintained by varying depths and water-holding capacities of the soil and show a general trend of reduction of pattern with their increasing development.
