While reducing non-climate drivers can help prevent kelp loss from warming and MHWs, there is limited potential for restoration of kelp ecosystems after transition to urchin-dominant ecosystems . Current restoration efforts are generally small scale  and less advanced than those in ecosystems like coral reefs . Although abundance of herbivores limits kelp populations, there is limited evidence that restoring predators of herbivores by creating marine reserves, or directly removing grazing species, will increase kelp forest resilience to warming and extremes . Active reseeding of wild kelp populations through transplantation and propagation of warm-tolerant genotypes  can overcome low dispersal rates of many kelp species and facilitate effective restoration  .
