Protocols and/or Procedures

One of the main strengths of the long term ecological research program is that it allows us to evaluate changes in the ecological community against the background of natural long-term variability. This long-term context is particularly important when we seek to distinguish between changes caused by natural processes and those caused by human activities. SBC LTER has undertaken long-term measurements of the abundance of reef algae, invertebrates and fish within permanent transects at 11 kelp forest sites in the Santa Barbara Channel. These data represent one of the core research activities of SBC LTER and they provide a relatively comprehensive description of community structure and dynamics of kelp forest communities within our study region.

Uniform Point Contact (UPC) sampling is done to determine the percentage cover of algae and sessile invertebrates and different types of bottom substrate. UPC data are collected at 80 points uniformly positioned within a 1 m wide area centered along a permanent 40 m transect. See the protocol document for more information.
