- Desert Tortoise Density Maps -
These GRASS output maps show the results of the simulation
over time at current levels of military activity.
- Juvenile Tortoises -
The tortoise population is very patchy across the Fort Irwin landscape, even
though the density of juveniles increases over time.
- Adult Tortoises -
Adult tortoise densities also increased over time, but in a patchy distribution
similar to the juvenile tortoises.

A One Year Simulation Of The Total Number Of Eggs, Hatchlings, Juveniles, And Adults. (Each frame represents one month) |

At the start of the simulation, in January, there are no eggs or hatchlings. When the breeding season starts eggs are laid and they grow into hatchlings. There is not a big influx of hatchlings into juveniles and adults because there is a hight mortality rate for hatchlings.
