tie off

But the giant kelp forests have shrunk. About 90% of Tasmania's giant kelp has died off.

"A lot of fishermen refer to the fact that they used to be able to tie off at it, and it was almost thick enough to walk on. Well, the kelp hasn't come back at all."

Researchers have tried replanting giant kelp. Here, a young plant is tied to a brick, and dropped onto the sea floor.

The fishermen used to fasten a rope to the giant kelp so their ships wouldn't drift away. "At all" emphasizes the fact that the kelp nas not come back. It's your regular brick, but since it's heavy, the researchers were sure the young plants would not resurface, and thus have all the chances to sprout roots and grow again.
