Abstract

To develop a robust, generic approach to modelling uncertain processes that can be used in real landscapes, we constructed two spatial models. Both involved a sub-population model running simultaneously in parcels across a coverage, with movement into randomly chosen neighbours. An exploratory model investigated the dynamics of the sub-population process in a homogeneous (raster) landscape and explored how density dependence and movement interacted with spatial scale to affect model output. The second model applied the same sub-population dynamic across a spatially irregular, heterogeneous landscape based on UK habitat data. Wild boar (Sus scrofa) was chosen as a model species and the spread and abundance predicted by the applied model were compared with the limited field data suitable for this species in the UK.
