One of the Biosecurity Surveillance in Agriculture and Environment drawbacks of IDEs is that they are deterministic and provide for a continuous distribution of organisms rather than a discrete distribution of individuals. , 2001, 2003). While continuous space models can have attractive mathematical properties, their application to heterogeneous environments can be problematic. As biosecurity programmes frequently deal with spread through geographically fragmented host landscapes, another option is to look at the transfer rates of propagules between discrete areas.

5 Systematic analysis of risks and risk management We have already touched on the inherent need for systematic analysis as a cornerstone to biosecurity, and the following sections elaborate this theme. The lack of ongoing surveillance of wild populations of animals is considered a serious weakness to the early alert of new human diseases, because so many new epidemics arise from zoonoses (Office of Science and Innovation, 2006). This study in future synergies between human, animal and plant surveillance names three principles for improvement: • making better use of existing data; • • focusing monitoring better; and ensuring that the mandates and resources of key organizations match the need.

In this simplified framework, colonization deals with the internal processes within a defined area while dispersal deals with the exchange of organisms between areas. In simplest terms, colonization is the process of a defined area going from uninfested to infested. As any infested area poses a biosecurity risk, estimating colonization events is fundamental to the spatial management of invasive pests. , 2009; Simberloff, 2009). The 27 IPPC adopts the terminology of endangered areas to identify a region that favours the establishment of a pest of concern, while establishment is defined as the perpetuation of a pest in an area for the foreseeable future (FAO, 2012).
