About This Project

Mendocino County, California, is home to several native and non-native carnivorous plant species. This project aims to create a comprehensive set of herbarium voucher specimens representing Mendocino's carnivorous plant diversity. I hypothesize these vouchers will reveal previously unrecognized patterns of species distribution, hybridization, or invasion. This work will fill a critical gap in under-documented species to support ongoing research and management.

Ask the Scientists

What is the context of this research?

There is increased concern with the loss of fen habitat along the Mendocino County coast with the expansion of anthropogenic disturbance. These habitats hold host to a native carnivorous sundew, Drosera rotundifolia, which are well-adapted to the waterlogged environments of fens through their use of carnivory. As this species can only survive in these vulnerable habitats, they can be valuable indicators of environmental change. The primary threats to these ecosystems are the introduction of non-native species and anthropogenic land use changes, such as infrastructure development and the recreational use of ATVs. As the peat formations and hardpan soil of the pygmy forest take thousands of years to accumulate, alterations to these soils and hydrologic function can have major repercussions on the distribution, ecosystem function, and overall success of these species. This project was inspired by this ecological novelty and the opportunity to contribute to long-term botanical records.

What is the significance of this project?

Many of the carnivorous plant species in Mendocino County are under-documented in herbarium collections. Existing records often lack detailed locality data and can be outdated, inaccurate, or missing entirely. Collecting new voucher specimens can help a wide range of scientists and land managers verify which species are still present at historical sites or if non-native species have been introduced to sites. Having a more robust herbarium collection can inform land managers and researchers working on restoration efforts, wetland conservation, and understanding these sensitive botanical ecosystems to ensure they remain protected.

What are the goals of the project?

During the peak blooming season in July-August 2026, I will collect plant specimens that have their inflorescences attached and, if possible, plants that are in seed. All plant specimens will be pressed and submitted to the University and Jepson Herbaria within 120 days of collection. The Herbaria should make these specimens available on their online database as well. I aim to collect all species that have been distributed in mass at each site. There are at least 3 sites that have approved permits, and I'm aiming to include an additional 2-3 sites pending permit approval and feasible site access.
