  Citation × Citation Citation Abstract Copy Title: Watershed Management and Private Lands: Moving Beyond Financial Incentives to Encourage Land Stewardship Author: DeAngelo, Matthew Thomas Year: 2016 Public water utilities are tasked with providing high quality, inexpensive water often sourced from watersheds representing a diverse mix of public and private land ownership. There is increasing recognition amongst water resource managers of the role that private landowners play in determining downstream water quality, but bringing together landowners with a wide variety of land management objectives under the umbrella of watershed stewardship has proven difficult. Recently, a large number of "Payment for Watershed Services" programs have aimed to engage private landowners in watershed stewardship initiatives by offering financial incentives for adopting watershed best management practices. However, a growing field of research suggests that financial incentives alone may be of limited utility to encourage widespread and long-standing behavior change, and instead understanding landowner attitudes and non-financial barriers to stewardship program enrollment has become a focus of research. This research examines a population of rural landowners representing a diversity of agricultural, forestry, recreational, and investment objectives in the Clackamas River watershed, Oregon. I designed and distributed a mail and web-based survey instrument intended to measure land uses and land ownership objectives, attitudes towards watershed stewardship programs, barriers to enrollment in stewardship programs, and preferred incentives and goals that would promote enrollment. I received 281 valid responses for a response rate of 29%. I conducted two primary analyses: one focused on relating attitudes and barriers to intent to enroll in a watershed stewardship program, and one focused on identifying how diverse landowners differ according to factors influencing enrollment in stewardship programs. I found that landowners did not report financial considerations to be a primary barrier to enrollment and expressed low interest in receiving financial incentives. Instead, landowners reported that primary barriers related to lack of trust, ecological understanding, and concerns that stewardship program enrollment would be incompatible with their land management objectives. I do not discount the potential utility of financial incentives under certain circumstances, but emphasize the importance of addressing these other considerations before incentives can make a meaningful impact. I compared how barriers to enrollment were perceived by landowners with different land management objectives relating to production, investment, and conservation. I found that landowner attitudes were differentiated from one another primarily by their use of land for production purposes; however, I found a large amount of diversity between producers and non-producers in the degree to which they considered investment and conservation objectives in their land management, and these two variables added further explanatory power to understanding fine-scale differences in how landowner typologies relate to conservation programs.

Morgan, Knudson, Chris, Groffman, Peter M., Bettez, Neil D., Cavender-Bares, Jeannine, Hall, Sharon J., Heffernan, James B., Hobbie, Sarah E., Larson, Kelli L., Morse, Jennifer L., Neill, Christopher, Nelson, Kristen C., Ogden, Laura A., O'Neil-Dunne, Jarlath, Pataki, Diane E., Chowdhury, Rinku Roy, Steele, Meredith K. Year: 2014 Changes in land use, land cover, and land management present some of the greatest potential global environmental challenges of the 21st century. Urbanization, one of the principal drivers of these transformations, is commonly thought to be generating land changes that are increasingly similar. An implication of this multiscale homogenization hypothesis is that the ecosystem structure and function and human behaviors associated with urbanization should be more similar in certain kinds of urbanized locations across biogeophysical gradients than across urbanization gradients in places with similar biogeophysical characteristics. This paper introduces an analytical framework for testing this hypothesis, and applies the framework to the case of residential lawn care. This set of land management behaviors are often assumed-not demonstrated-to exhibit homogeneity. Multivariate analyses are conducted on telephone survey responses from a geographically stratified random sample of homeowners (n = 9,480), equally distributed across six US metropolitan areas. Two behaviors are examined: lawn fertilizing and irrigating. Limited support for strong homogenization is found at two scales (i.e., multi- and single-city; 2 of 36 cases), but significant support is found for homogenization at only one scale (22 cases) or at neither scale (12 cases). These results suggest that US lawn care behaviors are more differentiated in practice than in theory. Thus, even if the biophysical outcomes of urbanization are homogenizing, managing the associated sustainability implications may require a multiscale, differentiated approach because the underlying social practices appear relatively varied. The analytical approach introduced here should also be productive for other facets of urban-ecological homogenization Title: Assessing the Homogenization of Urban Land Management With an Application to US Residential Lawn Care Author: Polsky, Colin, Grove, J.

  Citation × Citation Citation Abstract Copy Title: Contested Landscapes: An Analysis of Using the National Historic Preservation Act (NHPA) for Traditional Cultural Properties (TCPs) in the Western United States Author: Barcalow, Kate Monti Year: 2015 In this paper, I predominately use a political ecology lens to evaluate the use of the National Historic Preservation Act (NHPA) in facilitating American Indians' engagement with ancestral lands now federally governed. I look at how agencies can implement effective consultation that lessens the power imbalance between tribes and the federal government that is inherent in the NHPA, as well as help alleviate conflict between tribes, agencies, and various public interest groups regarding proper land management and use. From July 2014 through December 2014, I conducted eleven semi-structured interviews of participants involved with five Traditional Cultural Places or Properties (TCPs) in the Pacific Northwest and Southwest, as well as fourteen other individuals involved with TCPs. I used inductive coding to identify themes related to contextual factors that support effective consultation, and thus management, of TCPs. The themes I identified include federal agencies facilitating stronger relationships through effective communication and cultivating cultural understanding, incorporating the way tribes view the landscape into consultation and management practices, and proactively building relationships outside the compliance context. I argue that these themes support a more collaborative approach in managing these culturally important places, which facilitates tribes' reconnection with traditional areas, lessens conflict regarding proper land management and use, and strengthens self-determination through increased recognition of tribal sovereignty. This research further adds to the discussion of power dynamics between indigenous peoples and national governments regarding the management and governance of indigenous ancestral lands.

  Citation × Citation Citation Abstract Copy Title: The Wilderness Problem: A Narrative of Contested Landscapes in San Juan County, Utah Author: Banis, David Year: 2004 Wilderness preservation has been at the center of debates about public land policy for almost half a century, and nowhere has the controversy been more intractable than in Utah. Despite its vast expanses of unsetded and undeveloped red rock desert, managed primarily by the Bureau of Land Management (BLM), Utah has less designated wilderness than in any other state in the West. In this study, I focus on San Juan County in southeast Utah to study the conflict over the designation of wilderness. The controversy pits local residents and state politicians against state and national environmental groups, with the BLM shifting positions in between. I analyze and interpret the wilderness debate from three different perspectives. The fIrst explores the history of the Utah wilderness debate from the first BLM wilderness inventory in the 1970's through its re-inventory in the 1990's. I examine the influence of national, regional, and local forces such as institutional change within the BLM, in-fIghting among Utah-based environmental interest groups, and the sagebrush rebellion and county supremacy movements. The second perspective incorporates the spatial analytical techniques of geographical information systems to provide a relatively objective view of landscape characteristics used to defIne wilderness. I interpret the landscape as a continuum of varying degrees of wildness, a product of inherent naturalness and the influences of human impacts. Lastly, I examine the personal views of the meaning of wilderness through the words of actual participants in the debate. In an analysis of the statements of both county residents as well as the Southern Utah Wilderness Alliance, I explore the mental images and ideas that influence the ways in which people value and understand the desert environment.

  Citation × Citation Citation Abstract Copy Title: The Role of Habitat Restoration and Conservation in the Changing Socio-economic Conditions of Grant County, Oregon Author: Senkyr, Kristen Lauren Year: 2012 Habitat restoration has socio-economic as well as biophysical impacts. In Grant County, Oregon a recent influx of funding and technical resources for habitat restoration has led to focused monitoring efforts there to better understand the impacts. This study explores how local land use and land management practices are changing in Grant County as a result of restoration and other drivers. In-depth interviews were conducted with 17 landowners, land managers, and long time residents to document the change they have observed and identify how they are adapting. The results suggest that many interconnected social, economic, and ecological changes have taken place in Grant County in the recent past, of which the increased focus on restoration and conservation is just one. Other significant changes include the decline of the timber industry, shifting land ownership patterns, intensified regulation of natural resources, and increased environmental awareness. Ways that the community is adapting and additional ways in which they might more successfully adapt to these changes were identified. Recommendations for how to contribute to a more resilient Grant County are presented for the regulatory, academic, and scientific communities.

  Citation × Citation Citation Abstract Copy Title: Pine Creek Conservation Area: 2013 Mapping and Monitoring Report Author: Nielsen, Eric M., Noone, Matthew D., Kagan, James S., Lee, Matthew T. Year: 2013 Pine Creek Conservation Area (PCCA), just northeast of the John Day River in Wheeler County, Oregon, was acquired in 1999-2001 by the Confederate Tribes of Warm Springs with support from the Bonneville Power Administration (BPA), to mitigate for wildlife losses created by the large, hydropower Columbia River Dams, particularly the Bonneville, Dalles and John Day Dams. Many thousands of acres of grassland, shrub steppe and riparian habitats were lost due to inundation, and the objectives of the acquisition included restoration of similar habitats. As part of an interagency agreement created in 2002, the Oregon Natural Heritage Information Center established a baseline monitoring program in 2002. This effort included the establishment of permanent monitoring plots to allow for a detailed assessment of vegetation change in the plant communities occurring at the site. It also included the development of an existing vegetation map, hopefully to allow for an analysis of overall vegetation change across the conservation area. The map showed the distribution of western juniper, native grasslands, big sagebrush, and weed-dominated areas at the site. In the eight years since the original map was made, a series of management actions, including juniper clearing, prescribed fires, and riparian restoration activities have significantly changed the vegetation at PCCA. In the spring and summer of 2010, the Oregon Natural Heritage Information Center, now the Oregon Biodiversity Information Center at Portland State University, visited the area to assist the land manager in developing a strategy for meeting the information needs of the Tribes and BPA in evaluating the success of the first decade of restoration. This report details that effort, which incorporated a combination of field inspection, photo-interpretation, and remote sensing-based mapping to assess change since the establishment of the conservation area, to lay a new baseline against which to measure future change, and most importantly to provide detailed information useful for land management decision making in the continuing restoration efforts.

IAPS can displace native aquatic plant species, impair recreation, and degrade water quality. Early detection of new invasions can improve chances for successful eradication or containment to reduce the risk of IAPS spread. The Oregon Department of Agriculture (ODA) lists the most egregious offenders as “Noxious Weeds” which are defined as plants classified by the Oregon State Weed Board that are injurious to public health, agriculture, recreation, wildlife, or any public or private property (ODA 2011). Several IAPS classified as noxious have been detected within the Medford District of the Bureau of Land Management (BLM) in Southern Oregon including yellow floating heart (Nymphoides peltata) and yellow flag iris (Iris pseudacorus). During the summers of 2010 and 2011, IAPS surveys were conducted at selected reservoirs, lakes, and river boat launches within the Medford District to determine the extent of IAPS infestations as well as the distributions of native aquatic plant species. This report summarizes results of the surveys and provides recommendations for management of IAPS within the Medford District. Observations of any invasive aquatic animal species such as New Zealand mudsnails (Potamopyrgus antipodarum) are also reported.
