  Citation × Citation Citation Abstract Copy Title: Hydrologic and Land Cover Effects on Sources and Fate of In-Stream Fluorescent Dissolved Organic Matter Author: Lee, Baek Soo P. Dissolved organic matter (DOM) is a critical component of the carbon cycle linking terrestrial and aquatic ecosystems. Although many factors influence DOM fluxes and quality in rivers, controls on DOM compositions in catchments of the western U.S. are poorly understood. UV and fluorescent spectroscopy is a simpler, faster, and less expensive DOM fingerprinting technique compared to techniques, such as nuclear magnetic resonance (NMR) spectroscopy or wet chemical fractionation, and could be useful for characterizing complex DOM chemistry. However, only 1 % of DOM is estimated to be fluorescent, and the utility of UV and fluorescent spectroscopy for DOM characterization needs to be further investigated. This dissertation applied UV and fluorescent spectroscopy to examine hydrologic and land cover controls on DOM chemistry in streams of 45 catchments in the forested headwaters and a mixed landscape of the Willamette River Basin, Oregon, based on two years of monitoring. This dissertation contributes three major findings. First, freezing of water alters DOM chemistry by preferentially precipitating aromatic DOM. Second, UV and fluorescent spectroscopy was able to discriminate DOM delivered from highly processed, proteinrich deep subsurface sources during dry seasons especially in forested headwater streams of the H. J. Andrews Experimental Forest (HJA), where nitrogen inputs are very low. In addition, fluorescent DOM chemistry differed among watersheds with varying forest management history. Third, although fluorescent DOM in a headwater forested system differed among land use history, fluorescent DOM composition did not vary among streams draining a well-mixed landscape of urban, pasture/hay, forest, and agricultural land cover types in the central Willamette River Basin, where nitrogen inputs to streams are relatively high. Dissolved organic carbon (DOC) concentration decreased and the fluorescent index indicated an increase in terrestrial sources of DOM from small (1st and 2nd order) to large (4th to 6th order) streams. A protein-like DOM component that was detected in the headwater forested study site (HJA) was not detected in stream samples from the middle basin study site. These findings indicate that in-stream respiration, fueled by nutrient additions from agriculture runoff, consumes bioavailable, labile DOM (proteins) preferentially relative to more recalcitrant, terrestrial sources of DOM along water flow paths from headwater streams to major rivers. This study shows the clear applicability of the fluorescent characterization of DOM in identifying hydrologic and landscape controls as well as varying DOM chemistry and functions throughout watershed ecosystems.

  Citation × Citation Citation Abstract Copy Title: Restructuring of land and community in the remote rural west : the case of Wallowa County, Oregon Author: Abrams, Jesse Since at least the 1970s, rural areas in the western United States, as elsewhere across the country and world, have been subject to social, economic, and political forces that have resulted in novel demographic and land tenure trends when compared to previous decades. Collectively, these processes of restructuring have created material effects in the form of diversifying patterns of land ownership, use, and economic relations and at the same time have precipitated social conflict regarding the legitimacy of various claims on rural space. In this case study, I examine in detail the manifestation of these interrelated material and symbolic dynamics within one particular community, Wallowa County, Oregon, as it experiences a wave of new rural landowners and associated changes in land access and use. I pay particular attention to the categories of "amenity-oriented" and "production-oriented" landowners, as well as year-round and seasonally-resident landowners, because these categories are situated at the center of local discourse regarding land tenure and use dynamics. Methods for this study include key informant interviews with 70 individuals, a mail-administered survey of 209 Wallowa County landowners, review of secondary data sources, and direct observation as a member of the Wallowa County community. This case study includes a land tenure and use history of Wallowa County, a review of pertinent quantitative land ownership and use data, and analyses of the symbolic (discursive), material (land use), and political dimensions of restructuring in Wallowa County. I discuss ways in which observed patterns of land tenure and use reflect complex influences, based ultimately in class, culture, livelihood, and associated identities and environmental ideologies. I pay particular attention to the contradictory nature of narratives of land ownership, rurality, and nonhuman nature and the ways in which these affect land uses and land use politics. I close with a series of recommendations for rural communities experiencing amenity-driven property turnover.

  Citation × Citation Citation Abstract Copy Title: Forests, farms & people: Land use change on non-federal land in Oregon 1974-2014 Author: Hubner, Dan, McKay, Neil, Gray, Andrew N., Lettman, Gary J., Thompson, Joel L. Oregon has done remarkably well in preserving forests, farms, and rangeland from development. Ninety-seven percent of all non-Federal land in Oregon that was in resource land uses in 1974 remained in those uses in 2014. Ninety-nine percent of all non-Federal land in Oregon that was in resource land uses in 1984, after comprehensive land use plans were implemented, remained in these uses in 2014. With the housing industry still reeling from the 2007 financial crisis and subsequent Great Recession, development of resource lands in Oregon hit a record low between 2009 and 2014. Development of resource land to low-density residential or urban uses is consistent with land use goals, plans, and zoning. Most development of resource lands occurs adjacent or close to existing developed areas, thereby minimizing development scattered though Oregon’s forests and farm lands. Structures continue to be built on lands remaining in forest, agricultural, and range uses at high rates, even after the implementation of county comprehensive land use plans. However, the impact of these additional structures on management of Oregon’s resource lands is lessened because most of the structures built are relatively close to land in low-density residential or urban uses. It is notable that for land in wildland forest use owned by forest industry and non-Federal public owners, both the rate of development of wildland forest to low-density residential and urban uses and the number of structures built on land remaining in wildland forest use remained low over the study period. Most development of land in wildland forest use occurred on other private (non-industrial) ownerships.

  Citation × Citation Citation Abstract Copy Title: Essays on the economics of land use regulation Author: Lai, Jiayin This dissertation consists of three papers on land use economics and regulation. The first paper reviews numerous past literatures on how land-use regulation, agricultural subsidies, and use-value assessment method affect land values. The second paper uses a theoretical model to analyze how imposing minimum-lot-size zoning and different designs of minimum-lot-size zoning policies affects land value. The third papers use land data from Oregon to investigate the price effect of minimum-lot-size zoning and potential impact of Measure 37 and 49. The first essay reviews an extensive collection of literature from most major applied economics journals in recent years. These past studies attempted to investigate the impacts of various land use policies, including minimum-lot-size zoning, open space protection, wetland conservation, etc. These studies demonstrate how land use policies might affect residents' land consumption, social welfare, land markets, local government finance, and urban development patterns. Various econometric and mathematical models have been used to overcome problems related to modeling and data, such as spatial correlation. The objective of the second essay is to investigate the effect of the minimum-lot-size zoning on land values versus the value of individual exemptions from the regulations. The study first assumes all residents live in a monocentric city and have the same income constraints, and then assumes that there are two income groups living in the monocentric city. Minimum-lot-size zoning is applied to the periphery of the city. As stated in the study by Jaeger and Plantinga (special report, June 2007), distinguishing between two concepts - the change in property value due to regulation and the value to a landowner of an individual exemption to a regulation – is important to estimate the potential impact of Measure 37 and 49. Therefore, this study will explore both cases: 1) the removal of minimum-lot-size zoning from all parcels, and 2) having a single parcel exempted from zoning. Both open-city and closed-city scenarios will be considered. The comparative statics will show how the zoning policy influences urban land values. In addition, a simulation will help to demonstrate the impact of policy changes. The third essay uses the two-stage hedonic model to estimate the demand for lot size. The first stage estimation allows us to estimate the marginal impact of zoning policies, while the second stage estimation is used to investigate how land values are affected by the non-marginal change in zoning policies, such as the elimination of zoning or changes related to Measure 37. In the first stage estimation, the zoning policy is assumed to have two conflicting impacts on the land value; the regulation reduces development opportunities while it also may provide more environmental benefits. In the empirical model, four Oregon counties are considered as separate land markets, and the distribution of consumers' tastes are assumed to be the same across the counties. This provides a tool for solving the identification problem in the second stage estimation.
