What would be the best name for the experimental design for this experiment on the effects of feral predator management on native mammal populations? The aim of the experiment is to investigate whether baiting for feral predators and olfactory deterrents will increase native mammal populations. Twenty locations are chosen at random within a large national park. At each location, two separate sites were allocated, and one of the sites randomly chosen as a baiting site, where baits targeting feral predators were employed. Within each of the forty sites, whether baited or not, two separate areas were defined. One of the two areas was randomly selected at each site, for deployment of an olfactory deterrent. Within each of 80 defined areas, a single camera trap was deployed. At the end of a certain period, the number of observations of native mammals is recorded for each trap.
