3
Gradients in the matrix Number of species being surveyed Information for designing unequal probability sampling Integrating the survey designs
4
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
5
Where to from here? Many PhD ideas!! Interesting discussions with Regional Councils NZ-wide survey Integrated surveys
