Abstract

A population of plants may be regarded as consisting of a two-phase patchwork in which areas of ground occupied by the species (`patches') alternate with unoccupied areas (`gaps'). A method of studying such patch-and-gap patterns is proposed. In this method, neither the number of individuals, nor the quantity of plant material in a patch, is taken into account. Instead, the patches themselves are treated as the primary units. They may be of various shapes and sizes and their boundaries will usually be ill-defined. Circumstances in which such patch-and-gap patterns may be considered random are suggested, and the causes and effects of non-randomness investigated. For random populations, a method of estimating the mean dimensions of the patches and gaps has been devised.
