Northern Kelp

Laminaria hyperborea

Sighting evidence at Mire Loch Wall, St. Abbs Head

Laminaria hyperborea forms the structural backbone of the upper Mire Loch Wall ecosystem, creating a forest with fronds up to 3 m long that casts deep shade and provides settlement substrate for hundreds of associated invertebrate species. Individual kelp plants are estimated to live 15 years or more and their holdfasts harbour an entire community of invertebrates — sea urchins grazing on the stipes, brittlestars clinging to the fronds, and wrasse hunting beneath the canopy. The reserve's protection has allowed this kelp forest to reach an ecological density rarely seen on the fished Scottish coast.

How is this calculated?

Sighting evidence is compiled from iNaturalist observation records within a set proximity radius, filtered for quality-grade observations. “Last confirmed” is the date of the most recent research-grade record. Record count covers a rolling 24-month window. Confidence reflects record count, recency, and consistency of seasonal signal.
