Mean kelp density (ind. m−2) at Fort Wetherill from 1980–81 in Brady-Campbell et al. (ref.19) and 2017–18 in this study. Error bars are SE for n = 2–3 belt transects or 10–20 quadrats (some errors within the diameter of the symbol). The gray horizontal dashed lines indicate mean densities from 1980 to 1981 and 2017 to 2018.
