The Relationship Between Forest Management And Stream Discharge In Mazumbai And Baga Ii Forest Reserves, Tanga Region, Tanzania, Shannon Duffy
The Relationship Between Forest Management And Stream Discharge In Mazumbai And Baga Ii Forest Reserves, Tanga Region, Tanzania, Shannon Duffy
Independent Study Project (ISP) Collection
Deforestation is known to alter hydrology by reducing interception, transpiration and infiltration capacity, and increasing runoff which all leads to higher stream discharge. For rural Tanzanian communities, surface water resources are crucial for meeting basic needs, so the integrity of headwater catchments need to be maintained to ensure their reliability. The objectives of this study were to a) map the streams in the two forests because none currently exist and b) determine the effect of deforestation on discharge variability. Over fifteen days of data collection, this study analyzed variability of discharge and the degree of correlation between discharge and rainfall …
Wildfire Exposure To Critical Habitat Of Endangered And Threatened Species In California, Kristin Butcher
Wildfire Exposure To Critical Habitat Of Endangered And Threatened Species In California, Kristin Butcher
Master's Theses
Researchers, fire ecologists and wildlife managers are concerned about impact to endangered and threatened species and their critical habitat due to the projected increase in future wildfires. Wildfires have been studied in California for the last six decades and have been increasing at an alarming rate since the 1980’s. In this study, I use the 2018 spatial dataset for critical habitat of federally endangered and threatened species located in the state boundaries of California and compare it to a spatial dataset for wildfires that have occurred over the span of 32 years (1984 to 2016). Trends are derived from spatial …

Virginia Non-Tidal Wetland Condition Assessment 2016, Tamia Rudnicky, Kirk J. Havens, Michelle Henicheck, Dave Davis, Kory Angstadt, David Stanhope
Data
This data set is a GIS-based landscape (Level one) assessment of the water quality and habitat benefits of non-tidal wetlands from the National Wetlands Inventory (NWI) in Virginia utilizing the 2016 National Land Cover Dataset (NLCD) and 2016 Tiger/Line roads. The model assessment uses remote sensing and GIS technology to characterize land use patterns and features around wetlands such as surrounding land cover and density of roads as well as individual wetland characteristics such as wetland size and type to determine the wetlands overall condition as related to habitat and water quality functions. The water quality analysis determines the percentages …
