Unexpected consequences of vertebrate pest control

Although indirect effects are important structuring forces in ecological communities they are seldom considered in the design of pest control operations. However, such effects may cause unpredicted and deleterious changes in other populations that could reduce or even negate the benefit to endangered species for which control is undertaken. Furthermore, the complexity and nonlinearities inherent in interacting ecological communities may cause thresholds in the strength of pest control employed to occur, on either side of which indirect effects could vary greatly in their magnitude and desirability.

We constructed a 4-species simulation model for a common pest community in New Zealand beech (Nothofagus spp.) forests – house mice, ship rats, stoats, and brushtail possums.
