Intertidal species abundances facing a multiple stress/disturbance experiment in St. Lawrence Estuary (Sainte-Flavie, QC, Canada) 2012-2013

Abundances (percent cover, counts or biomass) of rocky mid-intertidal macro-species measured through a multi-factorial in situ experiment of 14 months in 2012-2013 in Sainte-Flavie, Québec, Canada (48°37'42.5″ N, 68°11'55.7″ W).

Using 0.25-m² plots, we ran an in situ one-pulse experiment (removal of all materials to bare rock and then burning of the surface) followed by a full orthogonal factorial design of three press-type disturbances or stresses: grazer reduction, canopy removal, and nutrient enrichment. We evaluated percentage cover visually. Counts and biomass were obtained destructively at the end of the experiment.
