Fig. 4: Kelp forest distribution and associated economic value by region.
From: The value of ecosystem services in global marine kelp forests

Map of kelp distribution, total economic value per m2 per year (k), regional value (B). Lighter shade colours are for regions where distribution estimates were not available and therefore these values were not included in the regional value calculation.
