Energy And Climate Change Issues Around Csudh, Alex E. Perez, Tara B. Jones, Raju Bista, Parveen K. Chhetri

CSU Journal of Sustainability and Climate Change

Climate change is posing significant challenges to California’s energy sector. Extreme weather events (heat and cold) may pressure existing infrastructure. Many studies have indicated that extreme climate events would impact the energy system by affecting peak electricity demand. However, very few studies have been conducted to understand how disadvantaged communities (DACs) will be impacted. Because of unequal access to energy infrastructure (electricity generation and battery storage), DACs are more vulnerable to power outages due to the rising number of significant weather events caused by climate change. To address the issue of how DACs are disproportionately affected by climate change-related energy …

The prevalence of special-status plants within a landscape can be an indicator of the ecological health of that site, and therefore inform restoration efforts and post-restoration monitoring. Hesperevax sparsiflora var. brevifolia (short-leaved evax) is a special status species found within the Ocean Ranch unit of Humboldt, California. A primary threat to native plant communities are invasive plant species. Coastal dune ecosystems are largely dominated by invasive species, including Ammophila arenaria (European beachgrass). To work towards the eradication of A. arenaria, the California Department of Fish and Wildlife utilized treatment combinations of herbicide and prescribed fire at Ocean Ranch in …


Analysis Of Benthic Macroinvertebrate Response To Restoration Flows And Scour In The Trinity River, Northern California, Sarah Gutierrez, Julie Avina Jan 2023

Analysis Of Benthic Macroinvertebrate Response To Restoration Flows And Scour In The Trinity River, Northern California, Sarah Gutierrez, Julie Avina

Cal Poly Humboldt Capstone Honor Roll

This study investigates the ecological impact of restoration flows and scouring events on benthic macroinvertebrate (BMI) communities within the Trinity River, an ecosystem historically impacted by anthropogenic activities. Central to this study is the examination of how hydrologic alterations, especially the construction of the Lewiston Dam, have influenced these vital ecological indicators. Using data collected earlier in 2023 from a current study by Benjamin King, we analyzed BMI samples from three river sites (Junction City, Pear Tree, and Lorenz Gulch), both prior to and following a major scouring event in January 2023. This paper utilizes statistical analyses, including ANOVA and …
