Brief description

Maintenance and Update Frequency: notPlanned
Statement: A pilot study was conducted in November and December 2001 from February 2002 - June 2003, the Swan River was surveyed on 192 days.
The surveys occurred at least weekly, but often they were performed on several days within a week. The surveys were conducted in several habitat blocks:
1) Port Blackwall Reach
2) Mosman Bay and Freshwater Bay
3) Melville Waters: Lucky Bay - South of Perth YC 4) Milyu
5) Matilida Bay
6) Meville Waters: pelican Point and Perth Flying Squadron
Many of the survey days did not sample all habitat blocks as the sampling protocol was to stop the survey route if an appropriate focal animal was located (~50 focal follows over the study) or if sighting conditions were poor. The sampling effort was uneven across habitat blocks and was highest in the lower reaches of the Swan River. The majority of sampling occurred in the morning, particularly during summer (due to the sea breeze)
