Collection Description Metadata and Data
SBC LTER: Ongoing time-series of giant kelp forest community dynamics (KFCD) Data on the abundance (density or percent cover), size and biomass of ~250 species of kelp forest algae, invertebrates and fish, and the type and percent cover of bottom substrate are collected annually in summer within replicate 40 m x 2 m permanent transects at 11 sites in the Santa Barbara Channel (n = 2 to 8 transects per site). Data collection began in the summer of 2000 and continues annually to provide information on community structure, population dynamics and species change. Measurements of the bottom topography of each transect collected on a single occasion are also included. KFCD percent cover of algae, invertebrates and bottom substrate

SBC LTER: Ongoing long-term experiment of kelp removal (LTE KR) This collection includes data from a long-term experiment designed to test the ecological consequences of increased storm disturbance on the structure, dynamics and productivity of the kelp forest community. The experiment consists of paired 40 m x 40 m plots at five kelp forest sites located along the mainland coast of the Santa Barbara Channel. Increased disturbance frequency is simulated in one of the plots in each pair by removing giant kelp annually in winter while the other plot in each pair serves as a control that experiences natural levels of disturbance. Changes in the structure (e.g. species abundance, diversity) and function (e.g. primary production of understory algae, detrital accumulation) of the kelp forest community are measured 1 to 2 times per season in permanent 40 m x 2 m transects centered within each plot. Giant kelp is continually removed each seasonal within an additional transect in the annual kelp removal plot to evaluate the overall effects of giant kelp on the reef community.
