Meron, et al, 2002

Where these equations

describe plant growth

at a constant rate, with

compenstation for dry soil,

mortality, grazing, and

saturation due to limited

nutrients.


Plant spread is modeled

through a diffusion term.


Biomass vs. Precipitation

Cellular Automata

A set of rules that set the

state of a cell based only

on the states of the bordering

cells.

Future Directions

Make predictions about microscopic

growth in the Atacama Desert between

these 2 points, based on the CA.


Ask Chris McKay to validate the

predictions.
