#' Invertebrate abundances in a revegetation study
#'
#' Data from a study looking at the effect of revegetation on invertebrate communities 
#' (data from Anthony Pik, Macquarie University). Invertebrates were sampled in 4-5 pitfall
#' traps at eight sites that had undergone revegetation, and two sites that hadn't, and it
#' was of interest to see what the effect of revegetation was on the invertebrate community.
