On the Skagerrak coast the kelp Saccharina latissima has suffered severe stand reductions over the last decade, resulting in loss of important habitats. In the present study, healthy kelp plants were transplanted into four deforested areas and their patterns of growth, reproduction, and survival were monitored through subsequent seasons. Our main objective was to establish whether the kelp plants were able to grow and mature in deforested areas. We observed normal patterns of growth and maturation at all study sites. However, heavy fouling by epiphytes occurred each summer, followed by high kelp mortality. The study shows that the seasonal variations and the life stage timing of S. latissima make formation of self-sustainable populations impossible in the present environment. Most noteworthy, we suggest that fouling by epiphytes is involved in the lack of kelp forest recovery in Skagerrak, Norway.

- Global patterns of kelp forest change over the past half-century (2016, background): “However, where kelp resilience is eroding and leading to declines in abundance (7, 18, 54, 64, 66, 67), impacts to ecosystem health and services can be far-reaching (19, 25, 26, 68, 69).”
- The role of kelp species as biogenic habitat formers in coastal marine ecosystems (2017, background): “…epiphytic loading on kelps has been 344 observed under stressful conditions, such as periods of intense warming or low light and high 345 nutrients (Andersen et al., 2011; Moy and Christie, 2012; Smale and Wernberg, 2012), and, in 346 perennial species, as the old blade senesces at the end of the…”
- Large-scale shift from sugar kelp (Saccharina latissima) to ephemeral algae along the south and west coast of Norway (2012, background): “Temperature may also be crucial for meiospores, gametophyte development, and germination (tom Dieck 1993; Müller et al. 2009; Roleda 2009), but reproduction in Norway takes part during the cold (winter) season (Sjøtun 1985; Andersen et al. 2011) when sea temperatures do not approach lethal levels.”
- Modelling the cultivation and bioremediation potential of the kelp Saccharina latissima in close proximity to an exposed salmon farm in Norway (2013, background): “13 & 14) fit well with previous experimental studies (Brinkhuis et al. 1984, Sjøtun 1993, Andersen et al. 2011, Forbord et al. 2012).”
