National weeds distribution database (NWDD)

The National Weeds Distribution Database (NWDD) briefing outlines the needs of various agencies in addressing weed management challenges. It emphasizes the importance of weed risk assessment, current vs. potential distribution analysis, and effective categorization within pest management strategies. The NWDD aims to facilitate national-scale reporting and monitor changes in weed distribution while assessing strategy effectiveness. It proposes a reliable national database reflecting accurate historical and contemporary weed distributions, leveraging diverse data collection methodologies and fostering collaborative governance for efficient data sharing.

  3. Background 1/2 • Basse et al. Envirolink report for Environment Southland • A “simple, accessible, reliable national database showing accurate current and historical distributions of weeds” • Wide range of data collection and storage systems using different standards • Authorised server to harvest data from different sources • Minimum standard of species, date, co-ordinates (+type)

  4. Background 2/2 • Cooper & Carver scoping report for TFBIS • Manual aggregation • Quality management • 2 year establishment project $700k + $70k p.a. • 6 species, current and potential maps • 2-3 year enhancement project $400-600k • Auto-harvesting, predictive models, CBA tools, crowd sourcing • Establish governance • Wide support in principle, little support in $ • Cost/benefit issues
