Aerial seeding is a crucial way to cover large and otherwise inaccessible areas, and can facilitate post-fire reforestation or wildland restoration. However, when a seed lies on the surface, it can be damaged by weather conditions or eaten by wildlife, resulting in low germination rates.

A new biodegradable seed carrier design inspired by the self-drilling behaviour of Erodium seeds is described in a paper in Nature. The seed carrier has a higher implantation success rate than that of Erodium seeds. This technology may improve the effectiveness of aerial seeding to address agricultural and environmental stresses in degraded regions.
