BDBSA Project Metadata Detail

Survey/Project Number: 431          Total No. of Sites: 24755
Survey/Project Name: Kangaroo Aerial Survey
Abstract: The Kangaroo aerial survey project contains approximately 20 years (Starting from 1978) of data that has been collected by various people. Whilst counting Western Grey and Red Kangaroo numbers, counts for Emu's and camels were also collected and any other significant sightings. The flight path varies from year to year so anyone trying to interpret population numbers or compare years needs to contact the custodians about exact methodology. The Kangaroo count data is used to Prepare Management Plans to set annual harvest quotas and sustainably manage kangaroo populations on pastoral properties.
Start Date: 01/01/1978      End Date: 01/01/2020
Survey Type: Vertebrates only
Study Area Description: see map in Corporate Storage Area
         Vegetation: The Start date is approximate. When receive data, amend this date. Now known to be 01-Jan-1978. End survey date has been amended to accomodate more recent data and data collected into the future.
         Fauna: *** No fauna survey objectives recorded
         Vegetation: *** No vegetation methodology recorded
         Fauna: Survey method: - Consists of flying transects west to east or east to west across the four commercial harvest regions of SA - Fixed-wing plane is used for surveys with two (one on each side of plane) observers counting animals on either side of the aircraft within 200 m belt transect (400 m in total separated by approx. 200 m underneath the plane). Plane travels at 100 knots (185 km/hr) and 250 ft (76 m) above ground. - The smallest unit used is a 5km length (measured with a timer as 97 sec) with 7 sec break between each unit, therefore there is approx. 300 m between each unit not counted. - Each transect is made up of several to many units (uneven between transects). - Transects are 28 km apart (15 nautical miles, see map attached). Gawler sub-region lines flown annually since 1978. EP sub-region lines flown tri-annually since 1997. The method of survey is consistent, however the frequency of survey has varied between sub-regions due to differences in harvest rates. BDBSA does not store the absence data for this project yet.
