The Chumash Heritage National Marine Sanctuary: An Exploration Of Changing The Discourse On Conservation, Arielle Ben-Hur

Pitzer Senior Theses

In 2015, the Northern Chumash Tribal Council submitted a National Marine Sanctuary Nomination to establish the Chumash Heritage National Marine Sanctuary– a means by which to ensure the protection of one of the most culturally and biologically diverse coastlines in the world. On October 5, 2015, John Armor of the National Oceanic and Atmospheric Administration (NOAA) responded to the nomination, adding it to the inventory of areas NOAA may consider in the future for national marine sanctuary designation.

In my thesis, I explore how the nomination of the Chumash Heritage National Marine Sanctuary acts as a platform from which Traditional …

Island Invasion: The Silent Crisis In Hawaii, Sophia Janssen

Pomona Senior Theses

Keeping out invasive species may, upon first review, seem like a trivial environmental cry from ecologists and deep environmentalists; a belated wish to return to an undeveloped world where nature was pristine. However invasive species create problems that impact all of us and can have far more severe consequences than changing a stunning landscape. These problems are heightened in islands like Hawaii, where the fragile ecosystems have developed over centuries of evolution and adaptation. The introduction of a disease-carrying mosquito can put the people of Hawaii at risk to many vector-born illnesses and create an epidemic, taking human life. The …

Adapting To The Changing Tide: An Evaluation Of California’S Drought Policies And Future Mitigation Strategies, Lauren Dorsey

CMC Senior Theses

California endured an extreme and prolonged drought from 2012 until the winter of 2017, offering a fascinating yet tragic example of how drought impacts lives. Despite this recent and stark phenomenon, there is surprisingly little information about its effects and implications. This thesis aims to lessen this knowledge gap by asking how severe the drought was, how well the state responded, and what policies would increase California’s water security. It answers these questions by exploring the Golden State’s long and complicated water management history, which is necessary to understand the current drought policy framework; then, it collects the emerging literature …

An Examination Of El Niño's And Agricultural Runoff's Effect On Harmful Algal Blooms And California Sea Lion (Zalophus Californianus) Health In Monterey Bay, Nadine Lafeber

Scripps Senior Theses

An increase in marine mammal stranding and die-off events has been observed along the California coast. The exact cause to explain for these recent events is unknown, but El Niño and harmful algal blooms are established sources for temporary decreases in marine mammal health. To determine whether El Niño could be causing and amplifying harmful algal blooms, particularly in Monterey Bay where they occur frequently, data was analyzed from the Marine Mammal Center in Sausalito, California. Data analysis focused on California sea lions (Zalophus californianus), because they have the largest data set and are directly affected by harmful …

The Environmental, Social, And Economic Impacts Of Hydraulic Fracturing, Horizontal Drilling, And Acidization In California, Christina Whalen

CMC Senior Theses

The oil extraction mechanisms of hydraulic fracturing, horizontal drilling, and acidization have recently spread throughout the state of California. This thesis explores and assesses whether federal and state legislation should approve of fracking operations in California after studying its effects on human health, the environment, and the economy. This thesis assesses the impacts of fracking; analyzes the role of current legislation and regulation; compares California fracking to fracking in other states and countries; and provides recommendations for future action.

Sediment Removal From The San Gabriel Mountains, Mary C. Ferguson

Pitzer Senior Theses

The issue of sediment removal from the San Gabriel Mountains has been a complex issue that has created problems with beach replenishment, habitat destruction and the need to spend millions of dollars at regular intervals to avoid safety hazards. Most recently 11 acres of riparian habitat, including 179 oaks and 70 sycamores, were removed for sediment placement. Other sites including Hahamongna Watershed Park and La Tuna Canyon also face a similar fate. This thesis questions: How did we get to this point of destroying habitat to dump sediment which is viewed as waste product? What are the barriers for creating …
