By visiting the same sites each year, we can see how the eelgrass beds change over time. Data collected by the Estuary Program in previous years documented a steady decline in eelgrass from 2007 to 2017 as well as a small resurgence that began in 2019. Based on our observations so far, it appears that eelgrass continues to reclaim lost acreage, …

Bioassessment 2021: the results are in! How healthy are local creeks? Plus a new video!

Click here to watch the new bioassessment video now, or find it at the end of this post.   Annual bioassessment monitoring tells us about creek health Each spring, the Estuary Program heads up a bioassessment monitoring effort in our local creeks. The data helps us understand the health of our creeks and how conditions are changing over time. The effort has two main components. We collect benthic macroinvertebrates, which are bottom-dwelling animals visible to the naked eye that lack a backbone. These include creatures such as stoneflies, dragonflies, and aquatic snails. We also collect habitat measurements such as whether …
