On a large scale, we identified borders for kelp recovery and sea urchin persistence along the north-south gradient. Urchins move in "herds," and enough urchins may remain in the "barrens" of a former kelp forest to negate any attempt at regrowth. Obviously, the rock would be an abiotic factor. Abiotic Factors that Affect Kelp Health, Density, and Population Nutrient Availability Not unlike terrestrial plants, kelp requires nutrients such as Nitrogen and Phosphorus to grow and reproduce. The spatial distribution of kelp (Laminaria hyperborea) and sea urchins (Strongylocentrotus droebachiensis) in the NE Atlantic are highly related to physical factors and to temporal changes in temperature. Crude oil normally penetrates the fur of the otter destroying the air layer that is trapped next to its skin.
