Longterm Mushroom Monitoring in the Santa Cruz Mountains

As mushroom hunters, we enjoy traveling far and wide, bouncing from place to place and following the rains to stay with the season. But what happens when we focus on revisiting the same small areas whether there has been rain or not? And what if we take it a step further, and rather than just harvesting chanterelles or photographing the flashiest species, we take the time to pay attention to everything, counting individual fruitbodies and keeping track of changes from year to to year? Christian Schwarz undertook a project  to diligently quantify the mushrooms of the Santa Cruz Mountains over three years, supported by a grant from the Save the Redwoods League, and in 2020, some of his survey transects were burned in the CZU Lightning Complex fires. During this talk he shares the discoveries, lessons, and patterns that have emerged from this ambitious project.

About the Speaker

Christian Schwarz is a naturalist currently living in Santa Cruz, the land of milk (caps) and honey (mushrooms). He studied Ecology and Evolution at UCSC, and now spends his time photographing, teaching about, collecting, and researching macrofungi. He is coauthor of Mushrooms of the Redwood Coast. Fungi satisfy his curiosity with their seemingly endless forms – from the grotesque to the bizarre to the sublimely beautiful. Besides dabbling in mushroom taxonomy, he loves fish, plants, nudibranchs, moths, and dragonflies. He is passionate about citizen science, especially iNaturalist.

This program was part of a series in support of the exhibit Look. Act. Inspire. and was presented in partnership between the Norris Center, the San Lorenzo Valley Museum and the Santa Cruz Museum of Natural History.
