  Citation × Citation Citation Abstract Copy Title: Classifying Oregon lake-watershed ecosystems for regional water resources assessment Author: Jones, Randall Alan Year: 1987 Natural lake-watershed ecosystems in Oregon compose a diverse and valuable assemblage of land and water resources. With an increasing demand on lakes for recreation, water supplies, and aesthetic values and an increase in available data on Oregon lake systems, there is a need for applicable and timely scientific water management information about lake conditions statewide. This thesis is an attempt to summarize some of the data collected on natural Oregon lake-watershed ecosystems. The purpose of the thesis is to identify the most typical natural systems out of an initial data base of twenty-four variables, measured over ninety-eight lake-watershed ecosystems. The selected variables are reduced to five common factors using principal components factor analysis. K-means cluster analysis is used to create similar groups of lake systems. These groups are compared to ecoregions in Oregon and a typical, representative lake ecosystem is identified for each group. Results show that several lake systems of the state are unique.

  Citation × Citation Citation Abstract Copy Title: Mapping Human-Environment Connections on the Olympic Peninsula: An Atlas of Landscape Values Author: McLain, Rebecca J., Cerveny, Lee, Besser, Diane, Banis, David, Todd, Alexa, Rohdy, Stephanie, Kimball-Brown, Corinna Year: 2013 Occasional Papers in Geography Publication No. 7 The advent of computerized mapping has land managers’ ability to map the biophysical services provided by forested ecosystems. However, mapping the cultural services of those systems is more challenging. Human ecology mapping (HEM), which provides spatially-explicit depictions of the complex connections between humans and their environment, is an approach that can be used to improve understandings of the cultural services associated with landscapes. This atlas provides an overview of what HEM is and draws on experiences with a pilot project on the Olympic Peninsula in western Washington to illustrate what HEM data looks like and some of the ways in which it can be analyzed. Values and activity data were collected during 2010 and 2011 from 169 residents through a series of community workshops held on the peninsula. Density and diversity analysis indicated that the type of values and activities mapped as well as their spatial configuration and distribution differed depending on factors such as place of residence and gender. Values and activities were most strongly associated with national forest and state lands, and moderate to moderately steep terrain. The analyses exploring the relationship between values/activities and vegetation type and proximity to roads were inconclusive. Results from the pilot project indicated that HEM is not only useful for identifying where meaningful places and activities are concentrated, but also can help reveal important differences among subgroups as well as areas where conflicts in values and activities exist.
