National weeds distribution database (NWDD)

Briefing for Dataversity

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

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)

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

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

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
