| Survey/Project Name: | Re-sample Nullarbor survey sites for monitoring potential |
| Abstract: | Resample sites established for "A biological survey of the Nullarbor Region South and Western Australia in 1984" (McKenzie and Robinson 1987) to evaluate survey site potential for long term monitoring at a regional scale. Sites will be resampled using original methods where practical. Refinements in methodology and new metrics have been incorporated into the 2012 program to increase its applicability to monitoring potential changes related to long term climatic variation, and to assess the potential impact of some of the other drivers in this system. This survey builds on the infrastructure and information collected for Survey No. 14 (1984). |

| Objectives | |||
| Vegetation: | The original 2km x 2km vegetation quadrat (site) has been reduced to a more manageable 1km x 1km site and will only be systematically sampled at traplines for vertebrates and assocaited 1 ha quadrats for vascular plants. Details of methodology will be published in final report as a journal article. | ||
| Fauna: | The sites used in this survey will have identical locational information for Photo Monitoring Points and the location of permanent pitfall lines | ||
| Methodology | |||
| Vegetation: | Vegetation - standard 100m x100m quadrat for arid areas. Included trial of quantitative overstorey and understorey measures using a restricted wandering point transect method. Tree measures were abandoned because of time constraints but target species were GPS located to enable species cover to be monitored using staellite imagery. | ||
| Fauna: | Fauna sampling: Mammals and reptiles - standard pitfall and elliot trapping (6 pits + 15 Elliotts and no cage traps) over 4 nights. Mammal search restricted to sign in 16 x 4m wide x 25m long strip segments along the 400m perimeter of the vegetation quadrat. Only sign for medium to large mammals was recorded as tracks, scats, diggings or burrows. Data entered into BDBSA as species - method and the number of segments with presence for that method (maximum possible = 16) sign transect data indicated in comments for data retrieval. No searching for mammals and reptiles other than whilst checking traplines. | ||
