Researchers have designed a lightweight wooden carrier that corkscrews seeds securely into the ground, improving the odds of the landscape’s rehabilitation.
After a forest fire, land managers can speed up vegetation’s recovery by reseeding the crisped land, often from planes or helicopters. But success is uncertain. Birds eat the seeds, or they might not germinate if the soil is too hard. Now, researchers have designed a lightweight wooden carrier that corkscrews the seeds securely into the ground, improving the odds for the landscape’s rehabilitation.
To make the humanmade version, the team first softened thin strips of oak by boiling them with lye and sodium sulfite. Then, they shaped the strips by placing them on a mold, warping the wood’s internal fibers in different ways on the top and bottom so that they curl when moistened and uncurl as they dry . Over time, the seed-bearing carrier twists into a soft surface like a drill bit.
