Carbon Biogeochemical Cycling In The Sierra Nevada: How To Maintain The Sierra Nevada As Net Carbon Sink Over The Long-Term, Eric Canteenwala May 2021

Carbon Biogeochemical Cycling In The Sierra Nevada: How To Maintain The Sierra Nevada As Net Carbon Sink Over The Long-Term, Eric Canteenwala

Master's Projects and Capstones

The Sierra Nevada region is an important carbon sink, storing about 3500 MMTCO2e or eight times the total amount of carbon emitted annually throughout California. However, recent climate-driven disturbances such as wildfires, drought and bark beetle infestations threaten the stability of this carbon pool over the long-term. The existing literature on how treatments impact carbon biogeochemical cycling in the Sierra Nevada was reviewed and interviews were used to identify the top barriers to increasing the pace and scale of treatments. Combinations of forest management treatments such as thinning, prescribed fire and reforestation can help maintain the Sierra Nevada …


A Comparison Of Fuel Reduction Methods For Wildfire Risk Management And Climate Change Resiliency In Mixed Conifer Forests In The Sierra Nevada, Heather Navle May 2020

A Comparison Of Fuel Reduction Methods For Wildfire Risk Management And Climate Change Resiliency In Mixed Conifer Forests In The Sierra Nevada, Heather Navle

Master's Projects and Capstones

Wildfires in the mixed conifer forests of California’s Sierra Nevada have been a common and natural disturbance for thousands of years, historically occurring every 3 to 30 years. The flora and fauna of the mixed conifer forest have evolved to depend on low to moderate severity wildfires for reproduction, foraging, and habitat. However, the Sierra Nevada has experienced dramatic environmental changes over the past ~150 years as a result of three main factors: wildfire suppression, climate change, and habitat loss. Because of the threat wildfires pose to human lives, property and timber harvest, they have been suppressed to an extent …


The Relationship Between Wildfire Dynamics And Soil Carbon In Boreal Forests Of Alaska: Forest Management For Emissions Reduction In A Changing Climate, James D. Heaster May 2017

The Relationship Between Wildfire Dynamics And Soil Carbon In Boreal Forests Of Alaska: Forest Management For Emissions Reduction In A Changing Climate, James D. Heaster

Master's Projects and Capstones

The boreal region of Alaska has vast forests spanning hundreds of thousands of square kilometers in the central portion of the state that is prone to large stand replacing summer wildfires. The region stores considerable quantities of terrestrial carbon sequestered in soil horizons down to 1 meter in depth that are strongly influenced by a combination of climate change, permafrost dynamics, vegetative composition, and fire regimes. Data and literature establish that the boreal region of Alaska (and the rest of the Arctic) has been steadily warming at a rate nearly double that of lower latitudes. This warming has resulted in …
