Typical output produced by the stochastic, individual-based model when naïve, unvaccinated animals are turned out on to contaminated pasture on 1^st April and followed until 31^st October.

Initially, the pasture contained 50,000 metacercariae. A further 500,000 were added between 18^th August and 13^th October. (a) shows the change in mean fluke burdens over time, (b) shows the change in individual mature fluke burdens (grey) with the change in the mean mature fluke burden (black as in (a)), (c) shows the mean distribution of total fluke burden on 31^st October.
