Standard methodologies
presently supported in NVS Express User Interface (UI):
– Recce inventory (Hurst & Allen 2007)
– Permanent plot method (Hurst & Allen 2007)
presently supported in the Main NVS database UI:
– EBEX21 (Richardson et al. 2004)
– Carbon Monitoring System or LUCAS (Payton et al.
2004)
examples of other standard methods:
– Wraight 20 x 20m quadrat (Wiser & Rose 1997)
– Scott height frequency (Wiser & Rose 1997)
Recce inventory
All vegetation types as per
Hurst & Allen 2007
Permanent Plot method
• Permanent 20 x 20m plots as per Hurst &
Allen 2007

entered via NVS Express?
