Sehome Hill Arboretum Trail Decommissioning Follow Up, Calvin Heslop
Sehome Hill Arboretum Trail Decommissioning Follow Up, Calvin Heslop
WWU Honors College Senior Projects
Maintaining accessible trail networks for recreation and travel is an important part of management in the Sehome Hill Arboretum in Bellingham Washington. Trails aid in bringing people into the arboretum so they can appreciate and enjoy what it has to offer. Additionally trails serve the purpose of limiting human impact to known and maintained areas. Unofficial “social” trails can be detrimental to both the accessibility and ecological function of the Arboretum. By adding to the existing trail network, these social trails can confuse park visitors as well as decrease the aesthetic value of the arboretum. Additionally, repeated traffic by hikers …
Fish Abundance And Habitat Recommendations Of The Lake Whatcom Tributaries, Ariel Edwards
Fish Abundance And Habitat Recommendations Of The Lake Whatcom Tributaries, Ariel Edwards
WWU Honors College Senior Projects
The tributaries of Lake Whatcom, Austin/Beaver, Anderson, Olsen, and Smith Creeks, provide essential habitat for many fish species native to the Pacific Northwest. However, development in the watershed has contributed to habitat alterations and even degradation of habitat quality. In this report, fish abundance and diversity, and habitat quality is compared both temporally, and among different streams. Anderson Creek was found to have the greatest species diversity. Cutthroat trout was the most abundant fish at each stream throughout the study period and was observed at every study site. Restoration recommendations for each stream were aimed at supporting existing native fish …
Soil Conditions And Arbuscular Mycorrhizal Fungal Spore Abundance And Distribution In Dewatered Reservoir Sediments After Dam Removal, Kari Clausen
WWU Honors College Senior Projects
Many dams in the U.S. are reaching the ends of their lifespans and dam removal as a form of river ecosystem restoration is becoming more prevalent. Revegetation of newly exposed sediments is an important aspect of ecosystem recovery after dam removal. Understanding the soil environment left behind after dam removal is important for understanding revegetation and ecosystem recovery trends. Physical soil properties and soil biota communities help to determine the success of plants colonizing exposed sediments after reservoirs are drained. I investigated soil properties and biota after dam removal by looking at the Elwha Dam Removal in Olympic National Park, …
Summer Climate And Western Spruce Budworm Outbreaks In The Pacific Northwest, Melinda Vickers
Summer Climate And Western Spruce Budworm Outbreaks In The Pacific Northwest, Melinda Vickers
WWU Honors College Senior Projects
Western spruce budworm outbreaks occur yearly with devastating effects for forests across Oregon, Washington, and British Columbia. However, as of yet, the relationship between these outbreaks and summer climate is poorly understood. In this study, I compared western spruce budworm outbreak records from Oregon, Washington, and British Columbia with June-August temperature and precipitation records between 1975 and 1995. This research reveals interesting patterns in the correlation between drought conditions and western spruce budworm outbreaks. My results necessitate further study examining the potentially significant relationship between summer drought conditions and western spruce budworm outbreaks.
