Faculty Jeff Kane Forestry, Fire & Rangeland Management In partnership with Redwood National Park and the United States Geological Survey- Arcata Field Office, Jeff Kane and graduate student Megan Joyce from the Department of Forestry, Fire, and Rangeland Management will be examining the impacts of restoration thinning treatments that burned in the 2023 Lost Fire on surface fuel changes, tree mortality, regeneration, and secondary redwood forests. Information from this study will aid managers in determining the ability of restoration thinning treatments to mitigate impacts from wildfire and will advance our understanding of fire effects in secondary redwood forests.

Faculty Dr. Lucy Kerhoulas Forestry, Fire & Rangeland Management Lucy Kerhoulas received a $180,000 grant from the Columbia Land Trust to investigate white oak responses to forest restoration thinning treatments aiming to reduce fire fuels, overstory competition, and tree drought vulnerability. This project will measure oak physiology before treatments and two years after treatments; findings will help hone management prescriptions to maximize Oregon white oak resiliency at the eastern edge of the species' range. The project is in collaboration with Oregon State University, the Natural Resources Conservation Service, the Columbia Land Trust, and the East Cascades Oak Partnership and will support one graduate student and numerous undergraduate students.

Student Regina Khoury, Brandon Browne Geology Regina Khoury (MS Student, Environmental Systems - Geology) and professor Brandon Browne (Geology Department) presented their original research poster in Spokane, WA, at the May 15-17, 2024 Geological Society of America Cordilleran Section Meeting. Their research poster, titled "Petrologic and Geochemical Constraints on Pre-Eruptive Storage Conditions of Magmas Erupted During the ~12.5 ka Flare Up of Medicine Lake Volcano, CA," described the results of Regina's MS thesis, including detailed field mapping of lavas and vents, whole-rock geochemical analysis of lavas and pyroclasts, and in situ chemical analysis of tiny crystals within lavas and pyroclasts.

Faculty Lucy Kerhoulas Forestry, Fire & Rangeland Management Lucy Kerhoulas received a $50,000 grant from Save the Redwoods League to examine the influences of Redwoods Rising restoration treatments on forest water sources and drought responses in Redwood National and State Parks near Orick, CA. Tree-rings, stable isotopes, and physiological measurements will all be a part of this work. Findings will help foster drought-resilient ecosystems by informing managers about how treatments influence forest water sources and what treatments most effectively maximize water availability for plants. Collaborators include Anthony Ambrose, Andrew Stubblefield, Alana Chin, Phil van Mantgem, Lathrop Leonard, and Jason Teraoka.

Faculty Pedro Peloso, Gisele Santana, Davi Pantoja, Geovania da Silva, Maiume da Silva, Gleomar Maschio (only Peloso is CSU faculty). Biological Sciences Professor Pedro Peloso was a co-author in the paper "Endemic amphibians of the Cerrado and Caatinga: species richness, geographic range and conservation" published in the Herpetological Journal. Their work highlights the distribution and conservation status of all species of amphibians that exist in two major ecoregions in Brazil (Cerrado and Caatinga). Based on geographic distribution data, they recorded 100 species that do not exist anywhere else in the world: 82 from the Cerrado and 18 from the Caatinga. They also discuss the role of formally protected areas in safeguarding threatened species in these ecoregions.

Student Kenia Gomez, Gabriel Abundis, Ernesto Chavez-Velasco Forestry, Fire & Rangeland Management Kenia Gomez, Gabriel Abundis & (graduate student) Ernesto Chavez-Velasco received research grants from the California Native Grassland Association to examine pressing issues on various California rangelands. Kenia will explore how drought and woody debris affect a local threatened species, North Coast Semaphore Grass; Gabriel will explore how local photovoltaic grids affect rangeland plant communities; Ernesto will work to develop field methods for selecting plants that will match with environmental characteristics for context-specific management to promote biodiversity and drought resilience on rangelands.

Faculty Lucy Kerhoulas, Rosemary Sherriff, Erik Jules, and Michael Kauffmann Forestry, Fire & Rangeland Management Lucy Kerhoulas, Rosemary Sherriff, Erik Jules, and Michael Kauffmann were awarded a $1.1 million grant to complete extensive vegetation mapping in the Klamath Mountains Ecoregion. Project vegetation surveys will be compared to vegetation surveys from the 1960s, 1980s, and 2010s to evaluate the influences of fire and climate change on high elevation plant communities.

The work will support three graduate students and numerous undergraduate students and will contribute substantially to the Cal Poly Humboldt Vascular Plant Herbarium; Robin Bencie and the California Native Plant Society are also project collaborators. Funding comes from the CA Department of Fish & Wildlife.

Faculty Alana Chin Biological Sciences Dr. Alana Chin received a grant to support research looking into factors impacting redwood tree fog-uptake. Redwood trees absorb water from fog, making it a key provider of water in the summer months. However, as the climate changes, so have fog characteristics, increasing the need to understand how redwoods are acclimating to changes in fog. The project will assess and monitor fog absorption capacity in redwoods, and is a critical next step in our ability to predict the impacts of climate change on redwoods and select nursery stock for restoration.

Funding comes from the Save the Redwoods League.
