QUAVONZ: Quaternary Vegetation of New Zealand

Establishing a database for New Zealand’s vegetation history over the past 50,000 years

New Zealand’s vegetation communities have undergone significant changes in composition and distribution during the past 50,000 years. These changes have culminated in the widespread loss of forests and expansion of grasslands following human settlement. The history of vegetation change is recorded by pollen grains and seeds preserved in swamps, and charcoal fragments and ancient DNA preserved in soils. Hundreds of these palaeovegetation records exist from across New Zealand, but are often difficult to locate in the scientific literature, or exist only as unpublished files, in ageing file formats, or on storage media that are fast becoming obsolete. Collation and preservation of these data are therefore of high necessity.

In order to address these issues, we are developing a databank and associated online interface for the collation and visualisation of data relating to the vegetation of New Zealand during the Quaternary (with a main focus on the past 50,000 years) (QUAVONZ: Quaternary Vegetation of New Zealand). The databank will allow contributors to log on, upload files and metadata, manage their datasets, and set security levels. This will ensure the data are protected for the future and available for easy access. The public online interface will use unrestricted data from the databank, and allow users to query records for particular locations, plant taxa or time periods of interest. Users will also be able to create customised diagrams, maps and animations, and if further details are required (e.g. for research purposes or publication) to apply to contributors for access and permission to use raw datasets.
