MORRO BAY WATERSHED NATIVE PLANT SERIES: Riparian Plant Communities

    This series of native plant blog posts has explored the different plants found throughout the Morro Bay watershed. A watershed is an area where freshwater creeks and streams flow from higher ground down towards the ocean. Riparian zone plants reach deep when streams run dry In the Morro Bay Watershed, some creeks and streams flow year round, and some don’t. Even though they’re not full of water, dry creek beds are still bordered by vegetation. This is due to the presence of groundwater, which is water that exists beneath Earth’s surface in soil pore spaces (the space between …

Field Updates March 2021: Volunteer Monitoring Program Updates and Bioassessment Site Scouting

Monitoring staff conducts bioassessment site scouting in the Morro Bay watershed

  Read each month’s Field Updates post to see what our Monitoring Team have been up to.  Updates on the Volunteer Monitoring Program As of March 2nd 2021, San Luis Obispo County moved from the purple or “Widespread” tier back into the red tier. The Morro Bay National Estuary Program’s current COVID-19 Safety Policy allows for volunteer monitoring when the San Luis Obispo County risk level is at or below the red tier designation, as outlined by COVID19.ca.gov. As such, the Estuary Program has slowly begun inviting back volunteers in a limited capacity. We have coupled this change with additional …

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 …

MORRO BAY WATERSHED NATIVE PLANT SERIES: Coast Live Oak Woodlands

  Coast Live Oak Woodlands Are Unique Oak woodlands are so characteristic and unique to our state that many think the plant community should be declared California’s state vegetation type. Not sure what a plant community is? Take a look at our introductory post to the Morro Bay Native Plant Series, an exploration of our watershed’s diverse native flora! The term “woodland” is used instead of “forest” because the canopies in a woodland rarely overlap, allowing for more space and sunlight between trees. Woodlands also typically occur on drier soils and at lower elevations than forests. Where to find oak …

Updates from the Field: Monitoring Eelgrass Expansion

Makenzie, Monitoring Coordinator, takes data while monitoring eelgrass in Morro Bay.

    The Morro Bay National Estuary Program’s fieldwork has been deemed an essential service by the County of San Luis Obispo. Due to COVID-19 safety precautions, we are not working with volunteers at this time and our field staff are following updated monitoring protocols. We look forward to working with volunteers and other community members again as soon as it is safe for us to do so. Thank you, readers, for staying engaged and supporting the Estuary Program’s work on monitoring eelgrass expansion and other projects during this difficult time.  Green, green, everywhere! If you’ve been out on the …

Community Scientists Make a Difference for Morro Bay

A plastic sand toy left on rocks at the beach.

  While not everyone can be a marine biologist, a meteorologist, or a conservation ecologist, anyone can contribute to the wealth of data that these experts use and study. Our own Monitoring program uses data gathered by community scientist volunteers and staff members to keep an eye on long-term trends in water quality, bacteria levels, and other factors that influence stream and bay health. (We are not working with volunteers at this time due to COVID-19 precautions, but we look forward to having our volunteers back in the field as soon as it’s safe to do so.) Today, we’re sharing …

Morro Bay Watershed Native Plant Series: Maritime and Mixed Chaparral

  Where do chaparral plant communities grow? Covering almost nine percent of the state, chaparral is one of the most widespread plant communities in California. Take a look at our introductory post to the Morro Bay Native Plant Series, an exploration of our watershed’s diverse native flora! Where can I find chaparral plant communities in Morro Bay? In the Morro Bay watershed, we see chaparral plant communities occurring in close association with the southern coastal scrub community and on higher, drier slopes. Since they are typically further inland from the immediate coast, chaparral plants experience greater temperature fluctuations (hotter summers …

First Flush in the Morro Bay Watershed: What goes down the drain?

First Flush Embarcadero

    Each fall, many of us busily prepare for the first big rain of the wet season. Homeowners might clean out gutters and put away patio furniture. Cities often run their street sweepers and vacuum out storm drains to prevent flooding. This past fall, the Estuary Program prepared for what is known as First Flush monitoring. What’s the harm in a little runoff? In the course of daily life, pollutants build up on our streets and sidewalks. Things like oil spills from cars, fertilizer from landscaping, pet waste, and trash can gather. When the first big rain arrives, these …

Central Coast monarch butterfly sightings If you live on the Central Coast or visit during the fall or winter, you’ve likely seen monarch butterflies making their way along the annual migration path. Driving down the freeway, you might catch the bright orange and black flash of monarch wings as they flit as fast as they can across the road,  fighting the wind whipped up by traffic. These insect athletes are built for distance rather than speed. The Western monarch’s annual migration of up to 3,000 miles is the longest on record, but their estimated average flight speed of of 5.5 …
