Archiving historic New Zealand Forest Service and Timberlands West Coast Forest Surveys

This project aimed to improve Metadata on some historical forest vegetation plot datasets archived in NVS. The New Zealand Forest Service (NZFS) and Timberlands West Coast (TWC, a former state-owned enterprise) established extensive sample plot networks throughout West Coast forests for informing sustainable timber production. We identified 67 datasets collected between 1962-1999. These extended from the Buller and Maruia catchments in the north, the Inangahua and Grey valleys in central Westland, to the Mahinapua, Mikonui, Wanganui, Whataroa and Karangarua districts to the south.

Once these datasets had been identified, our goal was to improve their future utility by ensuring that Metadata is as comprehensive as possible. We recently interviewed former staff of NZFS, who were involved in designing or implementing forest plot surveys on the West Coast. Key individuals visited the archive, poured over field-sheets and maps, and added any information that they could.

We acknowledge the Brian Mason Scientific and Technical Trust for funding for this work.

Missing Metadata are still an issue for some of these surveys. If you were involved in forest timber cruising or vegetation surveys for the NZFS, and may be able to help, please contact Jenny Hurst (nvs@landcareresearch.co.nz).

The NVS team has created an EXCEL template for entering data that are compatible with NVS that can be downloaded here. The files created can be readily uploaded into the databank. To achieve the highest level of data validation and integrity, the NVS team still recommends the use of NVS Express for data entry.

sPlot a new tool for global vegetation analyses

This paper presents the sPlot database that has collated vegetation plots globally as a tool to explore global patterns in taxonomic, functional and phylogenetic diversity at the plant community level. The NVS databank has contributed some public domain datasets to sPlot and is a member of the sPlot consortium. Click here to view.

New NVS search tool released

We have redeveloped the online search tool to make it easier for data users to discover data to meet their needs. The tool allows both text-based and map-based searching. Text-based searching uses intelligent syntax that is more user-friendly than previously. Users can search with any relevant word or phrase and users can narrow down search results by applying multiple filters, including species names. Map-based searching allows a user to browse plot locations across the entire map display or to focus on a specific area that they delineate. As with text searching, results from the map search can be refined by applying multiple filters. Search results identify what datasets are available, and how many plots within them meet the user’s criteria. We welcome any feedback you may have.

NVS User Survey needs you!

Periodically the team that manages the National Vegetation Survey (NVS) databank seeks input from users to help steer our direction for future years. We have designed a short survey to help our users provide this valuable input. Please take the survey here: https://www.surveymonkey.com/r/GWH3YXM Feel free to pass this survey on to others who may be interested
