From Pixels To Plants: Remote Sensing Of California Invasive Plants, Kenneth Rangel
From Pixels To Plants: Remote Sensing Of California Invasive Plants, Kenneth Rangel
Master's Projects and Capstones
Invasive plants cause significant impacts to ecosystems, the economy, and human health. California has experienced significant plant invasions and is well suited to future invasion because of its Mediterranean climate and human disturbance. Eradication or control of invasive plant species requires a detailed understanding of their spatial distribution, which typically involves on the ground surveys that can be expensive or inconsistent. Remote sensing offers a potential alternative or supplement to in-person invasive plant mapping. This study performed a comparative analysis of 41 remote sensing studies that mapped the distribution of California invasive plants. I found that while high spectral resolution …
Effects Of Land Use On Riparian Corridors In Sonoma County, Marina Davies
Effects Of Land Use On Riparian Corridors In Sonoma County, Marina Davies
Master's Projects and Capstones
Riparian corridor protection through zoning ordinances is a common best management practice to protect riparian ecosystems and function. These zoning ordinances protect riparian ecosystems by establishing setback distances where land use activities are prohibited. While management of protected riparian corridors are widely studied, recommendations for riparian corridor width vary and are often site specific. The variability of corridor widths presents a challenge to riparian corridor implementation, in addition to balancing economic needs with natural resource protection. This study evaluates the effects of land use on riparian corridors and compares the Riparian Corridor Combining Zone ordinance in Sonoma County to other …
The Potential For Marine Protected Areas In The San Francisco Bay, Samantha P. Delapena
The Potential For Marine Protected Areas In The San Francisco Bay, Samantha P. Delapena
Master's Projects and Capstones
The San Francisco Bay (the Bay) is the largest estuary on the Pacific Coast. This makes it one of country's greatest natural resources. Historical and current impacts from mining, pollution, and dredging have reduced the size of the Bay’s shallow, productive environment, which provides vital habitat for many important species. The seven and a half million people that inhabit the shores and hills surrounding the Bay, and economic activities such as commercial fishing and development continue to degrade ecosystems. Although conservation efforts have led to improvement of water quality and some habitat restoration over the past few decades, very little …
