Field Updates September 2017: Pikeminnow and Eelgrass

Collected seeds are held in mesh bags in the estuary until they mature. Mature seeds will have a hard, longitudinally ribbed coat and can vary in color, including olive, dark brown and black.

    Protecting and restoring the bay and estuary takes a lot of boots on the ground. See what our volunteers and field staff have been working on during the past month. Pikeminnow Management Chorro Creek used to be home to a healthy population of steelhead trout (Oncorhynchus mykiss), however their numbers have declined. While there are multiple factors that contribute to this, a fish called the Sacramento pikeminnow (Ptychocheilus grandis) put pressure on steelhead. Pikeminnow eat juvenile steelhead and compete with steelhead for food and habitat. While native to other parts of California, pikeminnow are not native to the Morro …

Field Updates August 2017: Eelgrass and Creeks

Matt, our Field Technician, works to identify and count the stages of the flowering shoots in a one-meter by one-meter plot.

  See what our volunteers and field staff have been working on during the past month. Eelgrass We completed our second round of 2017 small-scale experimental eelgrass transplanting in July, in collaboration with Cal Poly and California Sea Grant. In total, we planted seventeen one-meter by one-meter plots of eelgrass including nine in the forebay (across from the Tidelands boat launch) and eight in the midbay (across from Morro Bay Oyster Company). Though our midbay location was not as successful as the forebay site, we were able to glean useful information from these efforts, including which areas to target and …

Field Updates July 2017

George and Estuary Program volunteer, Nick, finish planting eelgrass shoots within a one-meter squared plot.

    Estuary Program staff and volunteers were hard at work in the field this past month. Fieldwork in July focused on preparing for a second round of eelgrass restoration. As you may recall, we collaborated with CalPoly on a similar effort in March, 2017. This effort was conducted earlier in the year than in past efforts in hopes that the eelgrass would become established before large macroalgae blooms, which typically occur during the summer here in Morro Bay. After four months, we were seeing growth and expansion of eelgrass at our forebay plot (or, eelgrass had expanded outside of …

“Time and tide will wait for no man, saith the adage. But all men have to wait for time and tide.” —Charles Dickens, The Life and Adventures of Martin Chuzzlewit   This saying about the inevitable march of time and the seasons can be traced back to the 1200s, but it felt very relevant at 5:00 this morning when Estuary Program staff and a few stout-hearted and warmly-dressed volunteers ventured out to the beach near Target Rock. There, we began the second round of the small-scale eelgrass transplant project that began back in March. Before setting the date for work to begin, staff had to monitor …

Field Updates June 2017

This dragonfly landed on a tree leaf, allowing us to see its intricate wing detail up close.

See what our volunteers and staff have been working on in the bay and watershed during the past month. Bioassessment The 2017 Bioassessment field season extended from April all the way into June. In June, we completed the final two surveys and then shipped off our bugs to the lab! We expect to have the bug scores sometime in the fall. One of our last surveys was on Upper Chorro Creek. The riparian corridor was teeming with dragonflies. Dragonflies are in the Order Odonata, which vary greatly in their tolerance level. Though the presence of these primitive creatures doesn’t necessarily …

Eelgrass Restoration in Morro Bay Spring 2017

Eelgrass isopod (Idotea resecata).

    Greetings, readers! This is Catie, the Morro Bay National Estuary Program’s Communications and Outreach Intern. I had the privilege of participating in the Estuary Program’s most recent small-scale experimental eelgrass restoration effort. We want to fill you in on the process here. Eelgrass (Zostera marina) plays a number of important roles in the function and health of the Morro Bay ecosystem.   Its long blades form an underwater forest, which provides a diverse crowd of creatures a place to rest, find food, and spawn. These are some of the creatures that we found during the replanting effort: The …

Field Updates February 2017

Carolyn does a test planting using bamboo garden stakes as an anchor and twine to mimic eelgrass.

Fulfilling our mission to protect and restore the Morro Bay estuary for people and animals requires a lot of hard work in the field. Read on to see what our staff and volunteers have been up to during the month of February. Sediment monitoring February was a quieter month for sediment monitoring, compared to January. We monitored two storms on Walters Creek in February, and we spent plenty of time processing sample bottles at our lab at Cuesta College, trying to empty them for future rounds of monitoring. Karissa went out with Catie, our Communications and Outreach Intern, to pick up bottles from …

December Field Updates, 2016

This horn shark hid in the eelgrass bed at State Park Marina as the tide receded. Horn sharks aren’t known for their speed and graceful swimming. Rather, they move slowly and like to hide among crevices in rocks, in kelp, and in eelgrass beds like this one was doing.

Fulfilling our mission to protect and restore the Morro Bay estuary for people and animals requires a lot of hard work in the field. Read on to see what our staff and volunteers have been up to during the month of December. Eelgrass Monitoring In 2005, with help from the Battelle Marine Sciences staff, we established four permanent transects for annual eelgrass monitoring in Morro Bay. These transects were chosen to represent different zones of the bay and capture differences between these zones. We added an additional transect in 2012. In December, we monitored two of these transects along with our other surveys. …

November Field Updates, 2016

Fulfilling our mission to protect and restore the Morro Bay estuary for people and wildlife requires a lot of hard work in the field. Read on to see what our staff and volunteers have been up to during the month of November.   Eelgrass Monitoring November was a busy month of eelgrass fieldwork for the monitoring staff. We continued monitoring the eelgrass restoration bed near Coleman beach and also took advantage of the great negative tides to conduct bed condition monitoring. These negative tides are great for fieldwork because of how much of the intertidal zone (the area that is exposed at a …

October Field Updates, 2016

Here, Shane places the quadrat at meter 75 of our 150-meter transect.

Fulfilling our mission to protect and restore the Morro Bay estuary for people and animals requires a lot of hard work in the field. Read on to see what our staff and volunteers have been up to during the month of October.   Fish trawl study We started off the month by helping Cal Poly Professor and California Sea Grant Extension Specialist Dr. Jennifer O’Leary conduct fish trawls in Morro Bay. In 2007, seven different sites around Morro Bay were trawled to catalog what species were present. Now, after the decline of eelgrass beds in the bay, the same sites are being trawled again …
