We are working with the state's SWAMP program to implement and refine newly developed protocols for phytoplankton sampling. Sampling began in Deer Creek in 2010 and will continue monthly from May to October each year at all our monitoring sites. Beginning with diatoms, our staff scientists have begun to identify the organisms found in the initial samples and to develop an identification key in the style of The Bug Book. This preliminary identification work marks the beginning of such efforts on the west coast, and as such provides a critical foundation for future phytoplankton identification by watershed groups and others throughout the region. Scientific leadership of this type is at the core of Sierra Streams' mission.
