A mechanic model explaining the effect of two-dimensional diffusion of a herd on biomass of natural grasses

If the natural grassland is a horizontal plane, then the grazing diffusion of the herd from a livestock shed is similar to the two-dimensional diffusion of heat and mass. This paper propounds four concepts: "almost grazing radius," "degeneration radius," "inflectional radius...

Description
Summary:If the natural grassland is a horizontal plane, then the grazing diffusion of the herd from a livestock shed is similar to the two-dimensional diffusion of heat and mass. This paper propounds four concepts: "almost grazing radius," "degeneration radius," "inflectional radius" and "stableness radius," and gives the corresponding expressions for all the radii.
