    Abstract

    This thesis investigated the re-establishment of soil ecosystem functions and ground-dwelling invertebrate diversity in a chronosequence of restored sites within two distinctly different restoration projects (mining pits and residue sand storage areas) associated with Alcoa’s bauxite mining operation in Western Australia. Both restoration practices are improving habitat characteristics towards reference sites, but changes to soil ecosystem functions were more rapid in mining than residue restoration with invertebrate seed dispersal lacking in the residue restoration sites.
