Deciding on appropriate scales – using the Surveillance
Hierarchy
The Surveillance Hierarchy is a first version of
one of the decision tools in the surveillance strategy. It
was produced as a response to the gap analysis that was conducted
at the
Vegetation Surveillance Workshop. The
hierarchy helps those who are commissioning or designing a
surveillance scheme to identify the appropriate scale for
surveillance. The scale will vary according to the type of
question that is being addressed. This paper will be updated
according to user feedback.
