Bioluminescent and UV Fluorescent Organisms of California

Mendocino Coast Botanical Gardens

You don’t have to travel to the tropics to see organisms that glow at night! California has organisms that are bioluminescent and produce their own light to attract mates, get rid of predators, or to help them find a new place to live. There are also plenty of organisms in California that are UV fluorescent under a black light, the biological function is a bit nebulous, but their glowing beauty is not. This talk will give a wide survey of these glowing organisms, where to find them, how to see them, and how to document them.

We will conclude the talk with a brief optional field walk to get an up-close look at some specimens and explore the Gardens. Class participants can also explore our wild mushroom collection on their own time armed with a list of species commonly found at the Gardens. The Gardens is home to more than 160 species of wild mushrooms during fall and winter!

The Details​​:

If you have one, bring a UV flashlight (recommended option).

Come prepared to use your cell phone camera to capture some of the glowing wonders and upload them to iNaturalist!

The class will include an indoor talk and a brief optional field walk outside. Be prepared for the weather with appropriate layers.

Bring a water bottle, paper, and a pencil/pen.
