All macroalgae and Centrostephanus and Heliocidaris urchins were cleared from this area immediately prior outplanting, to minimise the negative effects of competition and grazing on the planted juvenile Macrocystis. Within the cleared patch, the central 10 x 10 m area was to be used for outplanting while the 1 m ‘buffer’ on each side was intended to limit edge effects and allow assessment of any subsequent Macrocystis recruitment and patch expansion. Within that 10 x 10 m area, 100 expansion bolts were drilled into the rock substratum using a Nemo underwater rotary hammer drill. Bolts were separated by ~1m and arranged in a 10 x 10 grid and acted as the anchor point to install the planting substrates. The 10 ‘super kelp’ family-lines were cultivated to the sporophyte stage using the same methods as described above for the thermal tolerance experiment, with 10 replicates of each to be outplanted at each site. Plastic plates (40 x 40 x 1.5 mm) were used at the planting substrate. After being cultivated in the lab for 11 ± 2 weeks, each plate was transported to the field site in the individually sealed and labelled containers in which they were cultivated. At this time, sporophyte size was ~1–4 mm. The containers were then taken underwater, and each plate bolted to a random position on the reef and then labelled with a uniquely numbered cable tie. Each site was revisited ~3 weeks after outplanting to qualitatively assess kelp survivorship (since the kelp were still too small and delicate to accurately count), followed by a quarterly assessment thereafter.&rft.creator=Layton, Cayne &rft.creator=Johnson, Craig &rft.date=2021&rft.coverage=westlimit=147.944824219; southlimit=-43.146432197; eastlimit=147.991516113; northlimit=-43.1158001359&rft.coverage=westlimit=147.944824219; southlimit=-43.146432197; eastlimit=147.991516113; northlimit=-43.1158001359&rft.coverage=westlimit=147.386695089; southlimit=-43.1754747365; eastlimit=147.41416091; northlimit=-43.1544402157&rft.coverage=westlimit=147.386695089; southlimit=-43.1754747365; eastlimit=147.41416091; northlimit=-43.1544402157&rft_rights=Creative Commons Attribution 4.0 International License http://creativecommons.org/licenses/by/4.0/&rft_rights=The citation in a list of references is: citation author name/s (year metadata published), metadata title.

NESP Marine Biodiversity Hub Project E7. Results from the outplanting of lab-selected and cultivated warm-adapted genotypes of giant kelp (Macrocystis pyrifera), at two trial restoration sites. A third restoration trial site had no surviving kelp, so those data were not included here.
