Land use and land cover (LULC) mapping plays a vital role in understanding the state of the world, showing us a visual representation of the natural and anthropogenic features covering our planet. Northern California in the United States is home to many critical habitats that provide for a variety of endemic and some threatened and engendered species, making it an area of particular concern to better understand and monitor. There is a greater need to identify specific methods for vegetation modeling in Northern California due to its unique species; to do this we examined two case studies with the following …
Can A Remote Sensing Approach With Hyperspectral Data Provide Early Detection And Mapping Of Spatial Patterns Of Black Bear Bark Stripping In Coast Redwoods?, Shayne R. Magstadt
Can A Remote Sensing Approach With Hyperspectral Data Provide Early Detection And Mapping Of Spatial Patterns Of Black Bear Bark Stripping In Coast Redwoods?, Shayne R. Magstadt

The prevalence of black bear (Ursus americanus) bark stripping in commercial redwood (Sequoia sempervirens) timer stands has been increasing in recent years. This stripping is a threat to commercial timber production because of the deleterious effects on redwood tree fitness. This study sought to unveil a remote sensing method to detect these damaged trees early and map their spatial patterns. By developing a timely monitoring method, forest timber companies can manipulate their timber harvesting routines to adapt to the consequences of the problem. We explored the utility of high spatial resolution UAV-collected hyperspectral imagery as a …
Effects Of Thinning And Prescribed Burning On Tree Resistance To Extreme Drought In A Sierra Nevada Mixed-Conifer Forest, California Usa, Chance C. Callahan
Effects Of Thinning And Prescribed Burning On Tree Resistance To Extreme Drought In A Sierra Nevada Mixed-Conifer Forest, California Usa, Chance C. Callahan

Drought-induced tree mortality can drastically alter forest composition, structure, carbon dynamics, and ecosystem function. Increasingly, forest policy and management focuses on how to improve forest resistance and resilience to drought stress. This study used tree ring data at Teakettle Experimental Forest (TEF), a historically frequent fire mixed-conifer forest in the California Sierra Nevada, to quantify how prescribed fire and mechanical thinning conducted in 2001-2002 influenced stand and tree-level growth responses to the extreme California drought of 2012-2016. Overstory thinning and understory thinning significantly enhanced growth responses to treatments alone and treatments during the drought at the stand-level. In each year …
