There are data from 30 quadrats in the TGB Osborn Vegetation Reserve, varying in size and duration of measurements, several of which are shown in the Reserve map. They range in size from large quadrats (100 x100 m), one 60 x80m, to intermediate (10 x10 m) and small (1x1m and irregular). Most quadrats are inside the reserve but some lie adjacent outside the fenced area.

The data from the quadrats is presented in three different files:(a) the abundance (numbers) of individuals of species within the quadrat, (b) a selection of species measured within the quadrat (subplot), and (c) individual plant locations within the quadrats.

This is version 2.1 of the TGB Osborn Vegetation Quadrat data release and supersedes any previous versions. Change log for the metadata for the collection:

  • V3, 2026-03-26; Specht and Arun Singh Ramesh; Update to accompany V2.1 data files. Referenced geolocation file (https://doi.org/10.5281/zenodo.19177115). Changed the name 'subplot' to 'subquadrat' as an identifier. Removed data quality columns as no evidence to support them.
  • V2.1, 2026-02-06; Specht, Miranda Fittock and Arun Singh Ramesh; Ensured dates recorded were in ISO format YYYY-MM-DD. Updated geolocations, including two new columns, with NA used throughout for missing information. Expanded metadata text to explain better. Updated species list. Checked field comments for accuracy. Added data quality columns.  
  • V2, 2025-0701; Alison Specht; Digitised existing files, splitting them into synchronous categories, removing duplications and correcting errors to comply with FAIR standards. Aligned vocabularies with the TERN vocabularies, updated species names and created comprehensive metadata. Locations verified with David Ladd.  
  • V1, 2008-2014; Russell Sinclair; digitised field data sheets and computer records delivered to the AEKOS TERN portal. Added required V1 metadata in the AEKOS portal.
