I made some errors in my previous email responding
to Marilyn Davis's questions.
I have since learnt that there is a formal
requirement to notify the Australian Bird and Bat Banding Scheme (ABBBS)
of mortalities resulting from cannon netting. Banding data has to be
submitted at least once a year, and they require you to notify them of all
mortalities (numbers and species), and to provide a brief description of how the
mortalities occurred.
The ABBBS also requires you to provide a project
report each year (independent of the banding submission), in which the
objectives and outcomes of the project are described. The cannon
netting permit is dependent on them receiving and approving this
report. No project, no permit. The
regulations are appropriately very tight.
I also meant to say that 3 m is about the minimum
distance you'd want the birds away from the net when firing. It is normal
to put out markers (eg. sticks in the mud), marking the danger area, the optimum
firing distance, and the outer limit of the nets range.
