Emerald Ash Borer Study (EAB) Study
The data present in this folder represent a study submitted to a peer-reviewed journal for publication in September of 2023. This study models potential impacts of emerald ash borer-mediated Oregon ash canopy loss to temperature-related water quality on two waterways in the vicinity of Portland, Oregon: Columbia Slough and Johnson Creek. We employed existing water-quality software tools maintained by the State of Oregon with a combination of remotely-sensed data and field survey data to develop forecasts of changes in thermal inputs (legally, a pollutant under the Clean Water Act) and impacts to endangered salmon and trout species. Our results indicate a significant increase in solar loading with likely negative impacts to aquatic endangered salmonids, other aquatic wildlife, and associated habitat. We forecast greater impacts to these resources outside our study scope and include management considerations and recommendations for entities such as utilities, cities, and counties with water quality-related regulatory obligations. A link to this study will be made available, here, when that paper is accepted and open-source publication of that paper is funded. The data sets here are comprised of: 1. Field data representing vegetation values; here represented in Microsoft Excel format. 2. GIS data from the field surveys including geodatabases, shapefiles, etc. (note, some private property data was expunged from the datasets). 3. R-code for reproducible analysis of the above datasets. 4. Heat Source model files. Species of interest: Emerald Ash Borer (Agrilus planipennis) Oregon ash (Fraxinus latifolia)
