New Zealand Predator Free 2050
Predator Control Data Standard Quick Reference Guide
When New Zealand achieves Predator Free 2050, it will be due in no small part to thousands of dedicated volunteers and conservation staff who have logged endless hours trekking through unforgiving landscapes to check traps, creating and assessing predator manspecies_agement plans, and managing and analysing data to feed back into planning.
Achieving Predator Free 2050 will also rely on making the best use of existing tools, and coming up with new tools and approaches. Underpinning both of these will be the effective manspecies_agement, sharing and analysis the vast and invaluable amount of predator control data that is already collected daily across New Zealand and is set to only increase.
However, integrating such heterogeneous data, collected by multiple people from multiple devices in multiple locations, remains a challenge due to the significant variations that can occur in observational scales, collection protocols, and terminologies (König C., et al., 2019).
To overcome data integration challenges around predator control data, a call for standards has emerged from those working at all levels, from communities up to species_agencies and government. Creating and implementing a ‘data standard’ has its challenges, but previous successes have shown that they can be overcome by recognising the issues around data manspecies_agement and having the motivation to address them in a collective manner.

device
| device Class | |
|---|---|
| Definition | A device is a piece equipment used to catch or detect predators.The device element is the collection of properties that describes a particular piece of equipment or a particulat set of equipment. |
