Save Our Bees

Many bees on a honeycomb. One bee, marked with a yellow dot, is the queen.

  Bees are part of the food cycle in one of the most essential ways—they help pollinate our food. Why is this important? In order for plants to produce the fruits, nuts, and vegetables that we eat, bees (more specifically, worker bees) collect nectar and pollen from flowers. When they fly to another flower, they unintentionally rub that pollen onto the new flower, pollinating it [i]. There is more to the science, but basically, by doing this, the bee has fertilized the flower, making it possible for the plant to produce food. The lifeline of the bee Worker bees, which …

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 …

San Luis Obispo County’s Stealth Trees—Our Native Conifers

Monterey Pine

Guest post by Chris Hamma, biography below. San Luis Obispo County’s Stealth Trees—Our Native Conifers Overview of the trees of San Luis Obispo County In many ways, San Luis Obispo County is a throwback to “Old California,” with its beautiful landscapes of oak woodlands, chaparral, and grassland. If asked to describe the county’s flora, many of us might not think to mention… conifer forests? Though our county’s coast ranges are home to a variety of native coniferous trees, for the most part, they’re overshadowed by our more prolific native species. Our iconic oaks—coast live oak, valley oak, blue oak—virtually define …

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 …
