| Abstract: | The BCD (Biological Conservation Division) have conducted a series of aerial and ground surveys in several regions of the state to gain some idea of the extent and distribution of the Hairy-Nosed Wombat. These areas are: Eyre Peninsula, Far West Coast, Gawler Ranges - 2 surveys, Murraylands, Nullarbor and Yorke Peninsula. The information was plotted onto various different media, including photo mosaics, 1:250,000 photocopies. These bases were not vary spatially accurate. These maps were digitized and projected into a Lamberts cover, to be displayed at A3 scale. There maps were then converted to slides for a national conference on wombats at which Barb St John presented. Data Set comprises series of transects along which Southern Hairy nosed Wombat warrens were recorded at regular intervals. Transects were located in clusters at: Nullarbor region, Far West Eyre Peninsula, Eyre Peninsula (inland from Streaky Bay to Venus) and Murray Mallee.On average within each region there were 400 - 600 recording points along about 12 transects. The density of warrens per km has been recorded against these points. Survey dates range from 1980 to 1988. For each region, isolated records (outside of the transects) have also been noted (and additionally for Yorke Peninsula). Data entry notes: Observers have been entered as initials only. Other than BStJ (Barb St John) observers are unknown. For transect records, the density of warrens per km has been recorded. For numbers present, these should be entered as present but not counted, and the density of warrens entered against species comments |

| Fauna: | A separate project directory was created for each region and all work for that area done under the appropriate directory. The information was digitized with the naming convention of DIGIT1, TRANS1 etc. This was used because of the large number of mapsheets for each area. After the cover has been digitized an atool aml called WOMRUN.AML was run for the arc prompt. This aml processed the cover, transforming, buffering, adding items and coding the coverage. The next step was to run another atool aml in arcedit called WOMEDIT.AML which allowed the cover to be split at every segment and to be build as poly. Another aml called ADDSEG.AML added individual segment numbers to each transect, this had to be run for each transect in the coverage. This process was repeated for each mapsheet. When all were completed they were transformed into lamberts and appended into one coverage. The points were then reselected and put into a final TRANSECT coverage. The isolated points were also buffered transformed and appended to become a polygon coverage called ISOLATED. The trend analysis in grid was used to try to get some sort of distribution, and to do this another atool aml ISOWOM was run. | ||
