#' IBRA 7 polygons
#'
#' A SpatialPolygonsDataFrame of the Interim Biogeographic Regionalisation for
#' Australia (IBRA) version 7.0. The dataset comprises 9659 polygons
#' representing 89 biogeographic regions (419 subregions) that reflect the
#' biotic and abiotic environment across Australia. These data are provided by
#' the Australian Government Department of the Environment. More information
#' about IBRA 7 is available at
#' \url{http://www.environment.gov.au/land/nrs/science/ibra}.
#'
#' Multipart polygons were converted to single part polygons using QGIS 2.10.1,
#' and the resulting dataset was projected from GDA94 (EPSG:4283) to Australian
#' Albers (EPSG:3577) using \code{spTransform}.
