Under these methodologies, all threatened plants are treated as ‘species credit’ species (i.e. species that cannot be predicted by using habitat surrogates) and require appropriately timed on-ground surveys to determine the likelihood of their presence or absence at a site. This guideline has been prepared by using a variety of expert sources and should be read in conjunction with the relevant assessment methodology.
Following this guideline is not mandatory. However, proposals that fail to meet the guideline for reasons of efficiency, cost or validity will need to provide an evidence-based rationale for an alternative survey approach (e.g. an alternative published guideline or an expert report).
