In January 2016, armed militants occupied the Malheur National Wildlife Refuge, demanding an end to government control of the Refuge and other similarly protected public lands. Public discourse about the occupation highlights ongoing tensions around land use, property rights, and government overreach. The discourse foregrounds human animal concerns and all but erases nonhuman animal agency. This essay considers nonhuman animal agency and the entanglement of humans, nonhumans, and the land as seen in the occupation and surrounding discourse. We draw from critical animal studies and feminist posthuman theory to examine how discourses of the occupation produce and reinforce a sense of human exceptionalism that elides a more useful and nuanced understanding of human–nonhuman–land relatedness and agency. The analysis shows how, in the case of the Malheur occupation, occupiers and critics alike rely on discourses of “othering” towards both nonhuman animals and other humans. We take a “birding” perspective on the occupation to show how the webs of relationality that connect humans, nonhumans, and the land might be activated as an antidote to destructive discourses of human exceptionalism. 相似文献

Social vulnerability indicators can assist with informing disaster relief preparation. Certain demographic segments of a population may suffer disproportionately during disaster events, and a geographical understanding of them can help to determine where to place strategically logistical assets and to target disaster‐awareness outreach endeavours. Records of house fire events and American Red Cross aid provision over a five‐year period were mapped for the County of Los Angeles, California, United States, to examine the congruence between actual events and expectations of risk based on vulnerability theory. The geographical context provided by the data was compared with spatially‐explicit indicators of vulnerability, such as age, race, and wealth. Fire events were found to occur more frequently in more vulnerable areas, and Red Cross aid was found to have an even stronger relationship to those places. The findings suggest that these indicators speak beyond vulnerability and relate to patterns of fire risk. 相似文献

We estimate an individual travel cost model for Great Sand Dunes National Park and Preserve (GSD) in Colorado using on-site,
secondary data. The purpose of the on-site survey was to help the National Park Service better understand the visitors of
GSD; it was not intended for a travel cost model. Variables such as travel cost and income were estimated based on respondents’
Zip Codes. Following approaches found in the literature, a negative binomial model corrected for truncation and endogenous
stratification fit the data the best. We estimate a recreational benefit of U.S. $89/visitor/year or U.S. $54/visitor/24-h
recreational day (in 2002 U.S. $). Based on the approach presented here, there are other data sets for national parks, preserves,
and battlefields where travel cost models could be estimated and used to support National Park Service management decisions. 相似文献

We conducted a natural resource assessment at two national parks, New River Gorge National River and Shenandoah National Park,
to help meet the goals of the Natural Resource Challenge—a program to help strengthen natural resource management at national
parks. We met this challenge by synthesizing and interpreting natural resource information for planning purposes and we identified
information gaps and natural significance of resources. We identified a variety of natural resources at both parks as being
globally and/or nationally significant, including large expanses of unfragmented, mixed-mesophytic forests that qualify for
wilderness protection, rare plant communities, diverse assemblages of neotropical migratory birds and salamanders, and outstanding
aquatic recreational resources. In addition, these parks function, in part, as ecological reserves for plants in and wildlife.
With these significant natural resources in mind, we also developed a suite of natural resource management recommendations
in light of increasing threats from within and outside park boundaries. We hope that our approach can provide a blueprint
for natural resource conservation at publically owned lands. 相似文献

In the United States, the common interest often is conceived as a by-product of the pluralist, interest-group-driven democratic
process. Special interests dominate in many political arenas. Consequently, we have lost the language, vocabulary, and ability
to talk about the common interest. The way to reverse this trend is to develop and practice with new tools that allow us to
articulate what we mean by the common interest in specific contexts. In this article, we leveraged the literature on procedural,
substantive, and pragmatic decision making to illustrate how they work together to demonstrate whether and how the common
interest was served in three case studies of Healthy Forests Restoration Act implementation on the Apache-Sitgreaves National
Forest in Arizona. In two of the cases we found that the common interest was mostly served, while in the third case it was
not. Our results raise questions about the ability of procedural criteria or substantive criteria alone to determine effectiveness
in decision making. When evaluated together they provide a more complete understanding of how the common interest is or is
not served.

The dual goals of the Organic Act of 1916 and Wilderness Act of 1964 are to protect natural resources and provide quality
visitor experiences. Park managers need metrics of trail conditions to protect park resources and quality of visitor experiences.
A few methods of sampling design for trails have been developed. Here, we describe a relatively new method, spatially balanced
sampling, and compare it to systematic sampling. We evaluated the efficiency of sampling designs to measure recreation-related
impacts in Rocky Mountain National Park. This study addressed two objectives: first, it compared estimates of trail conditions
from data collected from systematic versus spatially balanced sampling data; second, it examined the relationship between
sampling precision and sampling efficiency. No statistically significant differences in trail condition were found between
the 100-m interval and the spatially balanced datasets. The spatially balanced probability-based dataset was found to be a
good estimate of trail conditions when analyses were conducted with fewer sample points. Moreover, spatially balanced probability-based
sampling is flexible and allows additional sample points to be added to a sample. 相似文献

This paper examines the attitudes and perceptions of local people about ecological resources, environmental hazards, and future land use of the Idaho National Engineering and Environmental Laboratory (INEEL). Such monitoring of attitudes is an important aspect of environmental assessment. We interviewed 262 people who attended the 42nd Annual Free Fishermen's Breakfast at St. Anthony, Idaho, on 23 March 1997. We tested the null hypotheses that there were no differences in perceptions about ecological resources, hazards and future land use of INEEL as a function of gender, age, education, and place of residence. Dumping trash in the ocean and cutting rainforests rated as the environmental problems of highest concern, and ozone, radon and high voltage lines rated the lowest; cleaning up Department of Energy sites rated intermediate. Respondents were most willing to expend government funds to make drinking water clean. Three significant differences were found: 1) women rated environmental problems as more severe than did men, and women were more willing to expend federal funds to solve these problems, 2) respondents under 30 years of age rated environmental problems as more severe than older people, and they were more willing to spend money to solve them, and, 3) respondents who had not finished high school were more concerned with environmental problems and were more willing to spend money to solve them than respondents with a high school education. Maintaining INEEL as a National Environmental Research Park (NERP) rated as the most preferred future land use, followed by continued reprocessing of nuclear materials and hunting. Using INEEL for housing and additional nuclear waste storage rated the lowest. Men rated grazing livestock and additional nuclear waste storage higher than did women. In general, respondents from 30 – 49 rated several economic uses (hunting, grazing livestock, growing crops) higher than did people in other age groups. Respondents with some college rated these economic uses higher than did respondents who had not graduated from high school. These results indicate that respondents living around INEEL believe that INEEL should continue with a reprocessing and NERP mission, but that other peripheral uses, such as hunting, hiking and grazing, should be allowed on some of the land. These views should aid in environmental assessment of the site, and in developing further management plans for INEEL. 相似文献

This paper describes one example of how the UK National Air Quality Strategy (NAQS) is implemented in a local urban environment. The paper reviews the beginning of this process, by examining the review and assessment procedures of the NAQS in the London Borough of Barnet. By the application of available UK tools of local air quality management (LAQM), the process began through analysis of the levels of local emissions and progressed onto modelling of current and future air quality. A map showing combined emission hotspot areas for the Borough indicated and higher emission rates occur in the south of the Borough and along the major transport corridors, as road sources dominate emissions. Dispersion modelling studies were also conducted for this purpose, using the screening models GRAM, PGRAM and ADMS Urban for an in-depth assessment. These analyses found that some local point sources and the majority of Borough roads with over 20,000 vehicles per day produced exceedances of the future objectives for air quality for some pollutants.Recommendations for the progression of LAQM in the Borough are made and include the update and expansion of the emissions information held for use in future modelling studies. The paper demonstrates the experience of implementing the Strategy, using the tools and procedures available for this purpose, in a local urban environment that is similar to many in the UK. 相似文献
