Doubling data on the Natural Values Atlas

​More than 1.5 million Tasmanian species records have been added to the Natural Values Atlas (NVA) from the Atlas of Living Australia (ALA).
The types of data recorded on the Tasmanian NVA includes:
  • Flora and fauna
  • Threatened species
  • Weeds
  • Tasmanian geodiversity
  • Soil surveys
  • TASVEG data
  • Threatened communities
Many data owners submit their records directly to the ALA and consequently, the Tasmanian data repository, the NVA, misses out. But that has now changed with the number of records essentially doubled since the project started in 2018.

The images below compare the number of bird observation records in the NVA before and after the addition of the ALA data. Bird records formed well over half the incoming ALA data. The number of bird observations in the NVA has increased from around 230,000 records to around 980,000 records.

​Moving the data involved a complex process that included:
  • Extracting data for the ALA
  • Quality checking and ‘cleaning’ the extracted data
  • Making the data compatible with the NVA 
  • Building a data loading tool so the records could be added to the NVA
Having these records available on the Tasmanian NVA has lots of benefits for the Tasmanian community. NVA data is regularly used for:
  • Development proposals
  • Education and research projects
  • Species conservation
The data is also used by other organisations including:
  • Tasmanian Fire Service
  • Sustainable Timber Tasmania
  • Forest Practices Authority
  • Tasmania Parks and Wildlife
The NVA team will continue to make regular updates from the ALA to ensure the data remains up-to-date. ​​
