||Baseline surveys for the Brown Toadlet, Pseudophryne bibronii, commenced on the 13th May 2009 and concluded on 2 July 2009. Surveys were primarily conducted by two people (one experienced herpetologist, and one volunteer or DEH staff member) although additional observers were sometimes also present. Surveys were focussed in parks in the central Mount Lofty Ranges. Within each park, sections of drainage lines and dams that were easily accessible from vehicles tracks (i.e. within short walking distance) were surveyed. Particular attention was paid to surveying areas within close proximity to existing records.
At each survey site the survey personnel listened for calling male Pseudophryne for a short period of time (1-2 minutes). If no calls were heard, or if calls were heard but verification was required, survey personnel imitated a Pseudophryne call or used recorded call playback (using an ipod and portable speakers) to try and elicit a response from resident male toadlets. After a short period of listening for responses, survey personnel then left the site, or if the habitat appeared suitable, continued searching further along the drainage line. On some occasions, calling individuals were precisely located by removing the surface soil and leaf litter covering them. Efforts were made to undertake surveys soon after periods of rain when possible. Surveys were not undertaken during unsuitable weather conditions i.e. during heavy rain and/or strong wind.
