The incorporation of landscape management into Conservation Biological Control
(CBC) strategies is a priority area of research but is hindered by a lack of harmonisation of the
means to describe and measure the effectiveness of CBC, the organisms under focus and the
landscape. This paper provides a set of recommendations that represents the consensus amongst
experts of the ENDURE network. The most important data values that were identified were: pest
population level; natural enemy population or % parasitism/predation; crop damage; estimate of
mobility of study organisms (dispersal function) and non-explicit spatial measurements such as
the proportion of the landscape offering resources and the connectivity between resource patches.
For all these measurements, careful consideration should be given to the appropriate spatial and
temporal scale of assessment. For analysis, we advocate an iterative use of modeling tools,
particularly individual-based models, and statistical approaches: the former to understand
mechanisms underlying the population dynamics of pests and their natural enemies in landscapes
and the latter to characterize the observed patterns of these populations in a given landscape.
