Botany

More than 500 species of plants are found on the UCSC campus! On just a short walk, you can travel through several ecologically diverse plant communities, including moist redwood ravines, mixed evergreen forests, knobcone pine forests, chaparral, grasslands, coastal prairie, and riparian/wetland areas. This astonishing botanical diversity is due in part to the diverse underlying geologic formations, topographic relief, and local climatic conditions found on campus.

 

Norris Center Resources 

The Norris Center is a member of the Consortium of California Herbaria (CCH). As part of the CCH, the Norris Center maintains an herbarium collection of over 8,000 fully cataloged vascular plant specimens, which can be searched online through the Jepson online interchange hosted at UC Berkeley. The collection focuses on Santa Cruz County plants, primarily collected by local naturalist Randall Morgan over the last 40 years. Morgan’s collecting especially concentrated on plants in rare habitats, such as coastal prairie, coastal dune, riparian, maritime chaparral, and sandhill chaparral. There are also extensive collections of the genera TrifoliumArctostaphylos, and Piperia. The museum has approximately 2,000 additional collected specimens waiting to be processed. With the help of volunteers and interns from UCSC, the Santa Cruz Chapter of the California Native Plant Society, and the community, the Norris Center processes and catalogs a few hundred plant specimens per quarter.

Nectar By Night: Nectar Patterns of a Trioecious Bat-Pollinated Cactus in Baja California Sur, Mexico

Norris Center Student Award winner Rozy Bathrick studied how different sexes of the Cardón Cactus (Pachycereus pringlei) produce nector for bat pollinators. Rozy found that female flowers produce significantly more nectar than male or hermaphrodite flowers. She also found that, by experimentally removing nectar to simulate bat visitation, that earlier bats may get more nectar than later ones. 

Identification Guide to Native and Non-Native Grasses at Younger Lagoon

UCSC undergraduate Michael Baca designed a helpful key and field guide to the grasses of Younger Lagoon.

Do Serpentine Specialists Have Weakened Competitive Ability and Higher Stress-Tolerant Traits Than Serpentine Generalists?

Norris Center Student Award winner Nate Blackmore used greenhouse experiments to test how competitive ability, water use and root/shoot ratios differed between serpentine endemics and serpentine tolerator species that were in competition with eachother. Blackmore found that there was no difference in root/shoot ratios or competitive abilities, but that endemics had a lower water use efficiency when in the presence of competitors. 

A Guide to Common Vegetation of the UC Santa Cruz Farm

Norris Center Student Award winner Michael MacDonald made a field guide to the common non-crop plants of the UCSC Center for Agroecology and Sustainable Food Systems.

California Conifers: Conifer Communities of the Santa Cruz Mountains and Interpretive Signage for the UCSC Arboretum and Botanic Garden

Norris Center Student Award winner Erika (Rikki) Lougee summarizes the conifer communities and species of Santa Cruz County, and highlights her experience designing signs to help others understand confier diversity at the UCSC Arboretum.

Heteroanthery in Clarkia cylindrica

Norris Center Student Award winner Diana Tataru created this multi-day time lapse video of a Clarkia cylindrica blooming to show off its two types of anthers. While watching, pay attention to the comparative phenology of the yellow, inner anthers and the purple, outer anthers. 

Soil Carbon Content of Sequoia sempervirens Forest Habitat

Norris Center Student Award winner Lilianne de la Espriella studied how soil carbon content varies along the range of Coast Redwoods. She found that soil carbon decreased moving higher in latitude, with implications for climate change in the northerly range shifts of Coast Redwoods.

Restoring California's Grasslands

Norris Center-affiliated graduate student Justin Luong talks at Grad Slam about his work measuring success in grassland restoration. Justin covers how grassland restoration occurs, and how we can adapt practices under climate change.
