Scientists have developed a scalable “holdfast-graft” method to reseed Tasmania’s lost giant kelp forests. By binding hatchery kelp to other seaweed stubs, divers achieved 40× higher survival. Within a year, the grafted kelp began reproducing—kick-starting self-sustaining forests. #GreatSouthernReef

A screen showing an underwater picture from the Great Southern Reef with kelp, coralline algae and an abalone. The title White Rock is centered over the picture, and there is a QR code at the bottom of the screen that says GET INVOLVED. Below the screen there are four bar stools set up for the panel after the screening.
A panel of two women and two men (from left to right) sit on barstools in front of a screen with an underwater photo from the Great Southern Reef and a QR code under the words MAKE YOUR VOICE HEARD. One of the women is holding a microphone, and the panel moderator is standing on the right of the group looking extremely thoughtful.
I really enjoyed attending a community event in #Torquay yesterday to watch #WhiteRock, a documentary with information and real solutions to combat sea urchin barrens on the #GreatSouthernReef 🪸 thank you to @greatsouthernreef.bsky.social for all their incredible efforts! #marineecology #fishsky
