Lidar-Landsat Covariance For Predicting Canopy Fuels, Margaret D. Epstein

Graduate Student Theses, Dissertations, & Professional Papers

Managing wildfires in the western United States is becoming increasingly complex. Visualizing and quantifying canopy structures allows fire managers to both plan for fire and track recovery. Light detecting and ranging, or LiDAR can measure forests in three dimensions, but has limited spatial and temporal coverage. LiDAR-Landsat covariance uses machine learning to fill in the spatial and temporal gaps of LiDAR coverage with supplemental Landsat imagery. However, in order to capture real forest dynamics, a model needs to be stable enough to detect long term trends, sensitive to episodic disturbance, and general enough to work on multiple landcovers. The purpose …

Therefore, this study was conducted to quantify erosion rates from native and gravel surfaced forest road segments after the August Complex fire, evaluate the impact of salvage logging activities on sediment production from roads, and understand the effect of soil burn severity on sediment production from these road segments. Finally, this …

Examining The Impacts Of Beaver Dam Analogues And Groundwater Storage On Miners Creek, California, Miles Munding-Becker

Cal Poly Humboldt theses and projects

Beavers have been altering streams in North America for millions of years by impounding water behind their dams. The recent historical removal (intensely throughout the 18^th and 19^th century) of these dams altered the hydrology in low gradient streams from dynamic anastomosing streams and wet meadow complexes to incised channels with little structural diversity. Anthropogenic structures called Beaver Dam Analogues (BDAs) are used as a restorative process by mimicking natural beaver dams that can reverse channel incision, increase ponded and groundwater storage, and provide low velocity habitat for aquatic species and vegetation. A system of four original BDAs …

Protecting Public Trust Resources In America's Private Forests: Case Studies In The Diversity Of U.S. State-Level Forestry Policies, Brita Ann Goldstein

Cal Poly Humboldt theses and projects

Privately-owned forests in the U.S. provide ecological and socioeconomic benefits to Americans. At the same time, they challenge common law principles that govern the administration of public goods. There is long-standing tension between private property rights, which entitles forest landowners to make land management decisions about their properties, and the role of state governments in protecting public trust resources on behalf of the general public. Each state chooses to protect public trust resources on private lands in a different way, meaning the U.S. is a patchwork of diverse private forest policy approaches. Describing this range of approaches can help inform …
