Spatially explicit disturbance/recovery models

Spatially explicit disturbance/recovery models are a cellular automaton that uses a mechanistic approach to investigate recovery rates of benthic species following disturbance events.

Complex interactions such as competition, facilitation, predation, density dependent growth as well as interactions to determine larvae settlement success are included.

Model summary

At NIWA, we used the spatially explicit/recovery models to assess the vulnerability of the benthic communities to disturbances. To do this, we simulate various disturbance regimes at different temporal and spatial sizes (Lundquist et al. 2010).
