Instead of counting the Weedy Seadragon numbers in Sydney dive sites, we will focus on monitoring just 5 key sites. We will do repeat visits to those sites 3 times a year and collect weedy density figure, ie. how many weedies per area.
The best way to do this is to use swim time along the sand-line where we typically find weedy seadragon for these sites. We each need to calibrate the general swim time so we know how long it takes to swim approx 50m with our own typical swim speed. This can be done during the survey exercise (beforehand) or individuals can do it before the surveys in their own time.
