Using standard collecting methods for Namibian desert areas, 6595 invertebrate specimens were collected in the Trekkopje Mining Area over a four week period in May-June 2008. This collection is intended to function as a pre-mining baseline for eventual use in the evaluation of the effectiveness of post-mining restoration. At least 135 taxa (= large unspecified groups of organisms) were recorded. Material has been deposited in the National Museum of Namibia, for distribution to taxonomic experts worldwide. The actual number of invertebrate species known from the area is expected to increase as these experts subject the 135 broad taxa to a detailed identification process.
