The negative binomial distribution function is used to characterize quantitatively the time-space distribution of excreta from freely-grazing animals over long periods of time; the Poisson distribution function was found to be reasonably accurate over short periods. Proportion of pasture covered by 0, 1, 2, . . . excretions during a grazing period appears to depend primarily on mean excretal density at the end of the period, and to be practically independent of the size and shape of the pasture.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
