The Distribution of Plant Populations

In studying the distribution of plant species in sample quadratsit may be assumed that the individuals are aggregated into groupsshowing a Poisson distribution, while the number of individualsin each group follows a logarithmic distribution. The resultingcompound distribution of individuals per quadrat is the negativebinomial. Evidence is produced to show that the distributionscalculated on this basis agree with those actually obtainedin the cases examined.
