MBHdesign: an R-package for efficient spatial survey designs
Abstract:
A considered survey design will generate data that are representative of the population that the sample is taken from. All good design takes is a little thought, some information and some good software tools.
Spatially balanced randomisation with unequal inclusion probabilities is a modern and efficient design method. These designs are embedded within sampling theory and should be easy to generate.
The R-package MBHdesign allows field researchers easy access to these designs. It implements point-based and transect-based methods and allows for the incorporation of legacy sites.
The functionality of the package is illustrated with example designs in an environmentally heterogeneous region.
A pilot survey in the Beagle Commonwealth Marine Reserve has found an unusually large group of Port Jackson sharks among sponge-covered deep rocky reefs.
