Gradients in the matrix
• Number of species being surveyed • Information for designing unequal probability sampling • Integrating the survey designs
Discussion points
• Temporal issues
– How often to resurvey? – Linked to timescale of RPMS
• Base survey – 200 sites for 5 years will give 1000 sites • Extra surveys for species and sites of concern
• Use of qualitative vs quantitative data, volunteers etc
Where to from here?
• Many PhD ideas!! • Interesting discussions with Regional Councils • NZ-wide survey
• Integrated surveys
