Field Updates, June & July 2019: Creeks, Road Restoration, Eelgrass

Shows a volunteer conducting water quality monitoring

  With summer in full swing, field staff at the Morro Bay National Estuary Program have greatly appreciated the long days. As always, we have been busy out in the field, collecting data from the watershed. Here are some of the things we’ve been up to recently. Creeks Our ongoing monitoring effort of the two subwatersheds, Chorro Creek and Los Osos Creek, that drain into Morro Bay allow long term trends to be established and we can see if current conditions vary from historical patterns. Chorro Creek is the main creek in our watershed, draining about 60% of the total …

Field updates April & May 2019: Monitoring Eelgrass and Creek Health

Two members from the Watershed Stewards Program lay out eelgrass blades on a white board for counting and photographing.

    Fieldwork season is in full swing now for us here at the Morro Bay National Estuary Program, and we have been busy hiking around the creeks and estuary to continue monitoring our local watershed. In April and May, we monitored eelgrass and conducted bioassessment monitoring to help us see how healthy our creeks are. Eelgrass monitoring Eelgrass monitoring continues as usual when the tides are low enough to let us collect data. This past month, there was a good window spanning multiple days where we were able to monitor for a couple hours each day to check on …

Field Updates February 2019: Wet weather, eelgrass restoration, and creek monitoring

A picture from the bridge at our monitoring site on Canet Road, overlooking Chorro Creek. What a difference a week and some good rain storms will do!

    Fulfilling our mission to protect and restore the Morro Bay estuary for people and wildlife requires a lot of hard work in the field. At the Estuary Program, that often entails doing research, restoration, and monitoring work out on the estuary and along the creeks that feed into it. Read on to see what we’ve been up to during the past month during this wet weather. Eelgrass February eelgrass restoration details This past month, we have been busy taking advantage of some of the year’s lowest tides to replant eelgrass throughout the estuary. The weather didn’t want to …

Field Updates January 2019: Eelgrass, Stormy Monitoring, Wildlife

Once the water levels dropped to safe wading levels, we went out to check on equipment and measure stream flow on Pennington Creek. This is at the site that previously had a fish passage barrier. The barrier was removed over the fall, opening up miles of Pennington Creek for migrating steelhead trout. Partners at other organizations have seen returning adult steelhead in a few other creeks in the county, so we are keeping our eyes open for ones in our watershed as well.

In the first two blog posts of the Factors that Affect Eelgrass Growth in Morro Bay series, we learned that there are many factors that influence eelgrass growth in estuaries. In this two-part post, PhD candidate Erin Aiello explores the importance of light levels and sediment properties and how they change across the bay. This is the second half of the post; read the first half here. Erin Aiello, Guest Author Erin Aiello is a native of the central coast, having grown up in Cambria. She spent most of her childhood running barefoot through pine forests, which instilled in her an undying …

Field Updates December 2018: Eelgrass, Wildlife Sightings, Creeks, and Rainfall Totals

Watershed Stewards Program members Melia and Doug work on counting the number of eelgrass shoots within a 0.5m by 0.5m area.

Fulfilling our mission to protect and restore the Morro Bay estuary for people and wildlife requires a lot of hard work in the field. At the Estuary Program, that often entails doing research, restoration, and monitoring work out on the estuary and along the creeks that feed into it. Read on to see what we’ve been up to during the past month.  Eelgrass monitoring Each fall, we monitor eelgrass on our permanent transects. These transects are sample areas across the bay where eelgrass has grown historically. We chose the specific locations of the transects to represent different zones in the …

Factors That Affect Eelgrass Growth in Morro Bay #2: Biological Conditions and Human Factors

    There are a variety of physical, biological, and direct human factors that affect eelgrass growth in estuaries. We have partnered with researchers at Cal Poly and Cuesta College to better understand these conditions in Morro Bay. This blog series, Factors that Affect Eelgrass Growth in Morro Bay, highlights our partners’ research. This second post will introduce you to the biological conditions and human factors that can impact eelgrass in our estuary. You can find the first post on physical conditions that affect eelgrass here.   Biological conditions Disturbance caused by crabs Crabs can disturb eelgrass blades by clipping them. However, …
