The California Phenology Network "100 Club"

The "100 Club" is an elite team of expert California botanists and naturalists who are helping to document the distributions of plant species by "georeferencing" plant specimens. Members of this team have extensive experience with one or more geographical areas, and they use this expertise to translate textual descriptions of specimen locations into latitude and longitude coordinates: dots on a map.

I chanced upon Job Kuijt’s “Parasitic Flowering Plants” at a used-book sale when I was an undergraduate, and was instantly smitten by the paradoxical concept of parasitic plants. I’ve been studying them ever since, specializing on the subterranean root-parasites in the genus Aphyllon (photo is of Aphyllon vallicola, grown from seed from Holy Jim Canyon). Because they are so dastardly hard to find, I had to rely on location information from herbarium specimens to find new populations, and that meant visiting herbaria wherever I hunted them, and before long, I was a fan of herbaria too. Since March 2020, I’ve been ensconced in my “own” herbarium and I’m finding it to be a delightful thing!

David Krause
My science interests are mostly in Botany, Ecology, and Mycology. I have long been a fan of wildflowers and mushrooms, exploring the California region from my home in Cambria. I am a long-time member of the California Native Plant Society and am active with the San Luis Obispo Chapter. Since my retirement, I have been able to enjoy more time in these pursuits. Other interests and activities include mountain biking, glamping in our travel trailer, woodworking projects, gardening, and remodeling our home.
