A way to measure the spread of plants from a focus

  • Jones RI

The relative frequency of occurrence of plants (or plant parts) is determined at increasing distances from a focus, where the relative frequency is unity. The area under the resulting frequency/distance curve is determined, as a measure of spread. Effect of treatments on spread can be compared by comparing these areas. A rate-of-spread index can be calculated from areas determined at successive times.
