Habitats and Rare Priority Protected Species (HaRPPS) data quality

Linkages between the species attributes in the HaRPPS database have been formed from a review of the literature, as well as from researching the experiences and expert opinions of practitioners within forest management.

The information flow model shows how the data quality value and a citation table operate as core features within the HaRPPS database. Every piece of information stored in the system has a citation and data quality value. HaRPPS therefore offers the transparency required when mixing evidence and experience-based information presented to a user or reviewer of the information.

The data quality table (below) provides a means of classifying the type and quality of information used in the database. Information is tagged in the review process to identify the source and its quality:

Classification of data quality in HaRPPS to allow the user or reviewer of the system to assess the reliability of the information provided by the system
Quality class Description


Peer reviewed papers and books


Web sites (known quality review process) and expert knowledge


Unpublished internal reports


Web sites (unknown review process)


Anecdotal experience

Information gained from the results of scientific research published in peer reviewed papers and books is given a classification 5.

Information may also be derived from un-replicated trials (3) and observations from rangers and managers (1), allowing its reliability and hence some of the uncertainty associated with the information to be considered.
