Bioassessment Survey Results 2020: Tracking the Health of Local Creeks

  One of the goals of the Estuary Program is to monitor the bay and the lands that surround it to better understand conditions and how they are changing over time. As part of this effort, the Estuary Program conducts spring bioassessment surveys. This data allows us to assess the health of our creeks and determine if they support sensitive aquatic life. What is bioassessment? Each spring, staff and volunteers head out to local creeks to collect habitat measurements. These measurements include the depth of the water, the size of the rocks in the stream, and the amount of tree cover …

  The California Rapid Assessment Method, or CRAM for short, is used to determine ecosystem quality for aquatic habitats. These habitats include wetlands, rivers, estuaries, and lakes. The Morro Bay National Estuary Program has used the CRAM assessment both before and after habitat restoration projects throughout the Morro Bay watershed to monitor habitat improvements over time. This method involves evaluating stretches of streams for their vegetation, stream bed complexity, bank stability, and the health of the surrounding ecosystem. To truly determine how healthy a stretch of stream is, you have to get your feet wet! Estuary Program staff have recently …
