Sites were chosen at progressive distances up the river in case there was some factor that moderated downstream such as pollution. Initially (1997/98 application) four transplant sites were chosen, these were Tranmere Reef, White Rock, Glenvar Bay and Black Jack Reef. The main donor site was the closest to the transplant sites with Macrocystis at the southern end of Blackman Bay. In order to determine if taking Macrocystis juveniles from donor sites had a detrimental affect on the beds at donor sites, a control donor site (Piersons Point) was chosen for monitoring. In case Macrocystis bloomed at all sites, and not just at the sites where we were trialling the planting process, thus giving a false indication of the success of the program, a control site on the eastern shore (Pidgeon Holes) was also monitored. Two surveys were done at each of the sites to account for seasonal variation (summer and winter). At each site a permanent transect line of 4 * 50m transects (a total of 200m) was laid. The transect lines were laid approximately along the 5m (+ 1m) depth contour line. This was used to conduct surveys for fish, invertebrate and algal communities at each site. Methodology was based on that used for marine park surveys (Edgar and Barrett 1997). Fish were surveyed at a scale of 500m2 per transect giving a total coverage of 2000 m2 at each site. Only mobile invertebrates were included in the benthic fauna surveys. These were conducted at 50m2 per transect giving a total coverage of 200 m2 at each site. Algal cover was measured using a 0.25m2 quadrat with 50 points. Cover was noted as the number of points intercepted and conducted one for every ten meters of the transects. Mercury Passage Four areas were chosen for the work in the Mercury Passage. These areas are Oakhampton Bay, Stapleton Point, Emerald Bay and Rheban (Graveyard Point). At each of these locations, five sites were marked by subsurface buoys attached to concrete filled tyres located at approximately 5m depth. The treatments areas were for a 5m radius around each tyre. The biologists surveyed for fish, invertebrates (1m^2) and seaweed (point intercept). Surveys were conducted at each of the sites quarterly for the first year and then annually (November - December) from then on.&rft.creator=Sanderson, Craig, Dr &rft.creator=Ibbott, Sam &rft.date=2007&rft.coverage=westlimit=147.90; southlimit=-42.65; eastlimit=148.00; northlimit=-42.55&rft.coverage=westlimit=147.90; southlimit=-42.65; eastlimit=148.00; northlimit=-42.55&rft.coverage=westlimit=148.30; southlimit=-41.300000000000004; eastlimit=148.40; northlimit=-41.20&rft.coverage=westlimit=148.30; southlimit=-41.300000000000004; eastlimit=148.40; northlimit=-41.20&rft.coverage=westlimit=147.35; southlimit=-43.05; eastlimit=147.45; northlimit=-42.95000000000001&rft.coverage=westlimit=147.35; southlimit=-43.05; eastlimit=147.45; northlimit=-42.95000000000001&rft.coverage=westlimit=147.45; southlimit=-43.10; eastlimit=147.55; northlimit=-43.00&rft.coverage=westlimit=147.45; southlimit=-43.10; eastlimit=147.55; northlimit=-43.00&rft.coverage=westlimit=147.30; southlimit=-43.10; eastlimit=147.40; northlimit=-43.00&rft.coverage=westlimit=147.30; southlimit=-43.10; eastlimit=147.40; northlimit=-43.00&rft.coverage=westlimit=147.35; southlimit=-42.95000000000001; eastlimit=147.45; northlimit=-42.85&rft.coverage=westlimit=147.35; southlimit=-42.95000000000001; eastlimit=147.45; northlimit=-42.85&rft.coverage=uplimit=6; downlimit=4&rft.coverage=uplimit=6; downlimit=4&rft_rights=Creative Commons Attribution 2.5 Australia License http://creativecommons.org/licenses/by/2.5/au/&rft_rights=The citation in a list of references is: citation author name/s (year metadata published), metadata title.

A project investigating the restoration of string kelp (Macrocystis pyrifera) habitat on Tasmania's east and south coasts. Macroalgae, fish and invertebrate counts were collected as part of the project using the Edgar Barrett transect technique in the Derwent Estuary and in the Mercury Passage on the South East Tasmania. Other fish, invertebrate and macroalgal data was also collected.
