These data are taxon-specific estimates of macroalgal standing biomass (grams dry mass m-2) recorded in 40 m x 2 m transects in of each sampling plot at SBC LTER's long-term kelp removal experiment sites. Estimates of macroalgal biomass are derived from measurements of abundance that are recorded as either density or percent cover. Density data are combined with allometric measurements to yield estimates of standing dry mass for taxa whose abundance is measured as density. Mean dry mass per individual is also reported for taxa whose abundance is measured as density. Taxon-specific data of percent cover are converted to biomass using relationships derived from field measurements of percent cover and laboratory measurements of dry mass. Data are updated annually.

The kelp removal experiment was initiated in 2008 at four reef sites along the mainland coast of the Santa Barbara Channel. The following three giant kelp manipulations are maintained in sampling plots at each site:

- Control: Macrocystis pyriferais left intact in a 2000 m2plot.

- Annual removal: Macrocystis pyriferais removed from an adjacent 2000 m2plot once each winter and allowed to re-colonize over the course of the year.

- Continuous removal: Macrocystis pyriferais removed from a 200 m2area within the 2000 m2 plot on each sampling date.
