  1. National weeds distribution database (NWDD) Briefing for Dataversity

  2. Identified agency needs • Weed risk assessment • Current vs. potential distributions • Weed categorization in pest management strategies • National-scale reporting • Changes in distribution • Effectiveness of strategies • Distribution data to parameterise models • Habitat/niche • Weed spread

  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

  5. First step solution • Online NWDD tool • Consistent with Australian approaches • Appropriate scale/resolution for identified needs • Leverage off DoC project (Howell) 180 spp • Hosted by developer • Cost $35k to date

  7. Next steps • Migrate to AgR management • Agency data sharing to generate data layers in Enterprise GIS • Stakeholder prioritization of development (GW and ES) • Relationships with other initiatives • Regional council data sharing (LAWA) • National science challenge (BioDiv & BioSec) • National Land Resource Centre • NZ Plant Conservation Network • PestWeb
