海带森林在全球范围内正在减少，可能需要大规模的干预措施来阻止这些宝贵的生态系统的丧失。到目前为止，海藻森林的恢复取得的成功有限，而且费用昂贵，无法解决生态系统日益恶化的问题。在这里，我们开发并测试了一种新的方法：“绿色砾石”。在实验室里，将海带播种在小石头上，直到2-3厘米长，然后种植到田间。外植海带在9个月内有很高的存活率和生长，即使从表面掉下来。这种技术便宜，简单，不需要潜水或训练有素的现场工作人员。它可以扩大规模，以处理大面积，甚至用于将更具弹性的海带种群的基因引入脆弱的珊瑚礁。因此，绿色砾石克服了目前海带恢复的一些主要限制，并提供了一个有前途的新的防御海带森林衰退。
Kelp forests are in decline globally and large-scale intervention could be required to halt the loss of these valuable ecosystems. To date kelp forest restoration has had limited success and been expensive and unable to address the increasing scale of ecosystem deterioration. Here we developed and tested a new approach: "green gravel". Small rocks were seeded with kelp and reared in the laboratory until 2-3 cm, before out-planting to the field. The out-planted kelp had high survival and growth over 9 months, even when dropped from the surface. This technique is cheap, simple, and does not require scuba diving or highly trained field workers. It can be up-scaled to treat large areas or even used to introduce genes from more resilient kelp populations onto vulnerable reefs. Green gravel thus overcomes some of the current major limitations of kelp restoration and provides a promising new defense against kelp forest decline.
