This dissertation consists of three papers on the use of incentives for conservation of endangered species on private land. The first paper examines incentives based on providing landowners with assurances regarding future regulation in exchange for their participation in a conservation agreement. The second and third papers are empirical analyses...
Species within marine ecosystems are known to be interconnected. This is
a result of many factors including predation and competition for resources.
Despite this, many fisheries are still managed using a single species
framework. This paper uses cointegration analysis to quantify the
relationship between different fish species. Cointegration is a...
During the summer of 1980 an infiltration/sedimentation study was
conducted on the Oregon Range and Related Resource Validation Project
Work Area in the Blue Mountains of east-central Oregon. A modified
Rocky Mountain infiltrometer was used to simulate a 28 minute high
intensity rainfall event to determine mean infiltration rates and...
A survey was conducted to create a comprehensive list of marine protected areas (MPAs) in Japan. There
exist more than 1,000 fishery cooperatives in Japan, and many of them have established no-take zones for
many years. Such zones are usually not reported to the government and, therefore, the complete picture...
This paper develops a count data model of target species and bycatch
production for an arbitrary number of species that handles correlation
between species and over time. The model is applied to a large observer
dataset for fishing trips taken from 1990 to 2008 for roughly 150 vessels
participating in...
In the quest to limit the bycatch of non-target species, marine protected
areas (MPAs) have been frequently utilized. MPAs are popular with
ecologists and fishery managers because of their relative ease of
administration, habitat protection benefits, and the widespread acceptance
of MPAs as an instrument of choice for the ecosystem...
The number of people traveling to other countries to volunteer for conservation or humanitarian projects has increased dramatically in the past three decades. Despite substantial interest in volunteer tourism, few researchers have examined: (a) the role of promotional material (e.g., brochures, internet websites) in motivating volunteers; (b) factors that attract...
Ruchi Glades is proposed for designation as a Research Natural Area. It is located on the upper slopes of Oregon Caves National Monument which is administered by the National Park Service. Ruchi Glads has an impressive diversity of plant communities for such a small area. The Oregon Natural Heritage Plan...
"This document is an interim report by the Heritage Program, submitted to the Oregon Parks and Recreation Branch. It summarizes: 1) the data collected on natural areas in private, county and municipal ownership throughout the state; 2) the techniques used to collect this data; 3) a system for storing, analyzing...
A qualitative research approach composed of three strategies was employed to systematically examine the politics of natural resource collaboration. First, using the Oregon Plan for Salmon and Watersheds as a case study, the behavioral assumptions of natural resource policy instruments enabling collaboration were uncovered and analyzed. Three key assumptions emerge:...
The paper reviews the management and bioeconomic modeling of the Southern Bluefin Tuna
stock. It describes two studies using simultaneous, non-cooperative, three player games to predict
revenue and stock outcomes generated by a deterministic, discrete, age-structured model of the
SBT population. Two versions of the model, corresponding to biological and...
Pacific sardine (Sardinops sagax), which is a transboundary resource
targeted by Mexican, U.S. and Canadian fisheries, has exhibited extreme
decadal variability in its abundance and geographic distribution
corresponding to water temperature regime shifts within the California
Current Ecosystem. Our study develops a three-agent bioeconomic
framework that incorporates environmental effects on...
In developed – and some less-developed – societies, managing an “open access,” renewable
natural resource sector generally involves taxes, quotas, or other government or community
restrictions. But some cultures, especially in their early years, have taken a different approach,
one that involves transfer of part of the output of the...
The last fifteen years have seen increased reference to and adoption of comanagement
in fisheries in Southern Africa, usually as a conditionality for
(national or international) development aid in the sector. Co-management is
supposed to improve the proficiency and efficiency of fisheries
management through decentralization and democratization of decisionmaking,
which...
Reefs and lagoons ecosystems of French Polynesia have been since a very
long time the support of important traditional activities. They are today
concerned by conservation public policies, which have considerable
consequences about the relations between local societies and their
environment.
The necessity to stop the degradation of marine biodiversity...
Since the seventies, the Malagasy fishery sector management has been
oriented by three paradigms: development, rationalization (looking for
economic efficiency) and attempts of sustainable development (to reconcile
economic, social and conservation goals). The institutional and legal frame
of the marine sector has been characterized by many transformations linked
to the...
Conservation goals and resource use can easily conflict when externalities
exist. This is the case in the Baltic Sea with grey seal (Halichoerus grypus)
and Atlantic salmon (Salmo salar). Both of the species have been defined
as critically endangered in the late 20th century but due to conservation
schemes, harvest...
Understanding the complexities of ecosystems is difficult enough, but when the human dimension is added to the inherent uncertainty and risk in fisheries management, the actual versus expected results move from the counter-intuitive to the paradoxical. Without an adequate understanding of the interrelationships between ecosystem components, including the human dimension,...
This thesis examines the application of findings from the social psychological field of
procedural justice to public involvement in natural resource decision making. The
methodological approach involves examining the literature of each of the fields and
developing a synthesis applicable to public involvement. The review of public involvement
literature reveals...
The Oregon Youth Conservation Corps (OYCC) is a youth work program
created by the Oregon Legislature in 1987. The OYCC provides both summer and
year-round employment programs primarily for disadvantaged and at-risk youth.
The legislatively defined purpose of the OYCC is to protect, conserve, and improve
the natural, historical, and...
Natural resource decisions require consideration at many levels, ranging from how one invertebrate will be affected by a nearby road, to how an entire watershed will be transformed by a massive clearcut. Considerations reach farther than just the local ecological community-human communities, economies, and future impacts on the communities and...
If the role of MPAs as a conservation tool is now widely demonstrated
even with some variability, their effects on fishery yields, tourism revenues
and social aspects are only confirmed by very few studies. More than 550
MPA now exist in the South Pacific mostly community based managedand
the expectations...
This study determines the optimal allocation of watershed conservation funds in the John Day River Basin, Oregon. Fund managers can use a variety of targeting schemes to allocate their limited resources. Depending on which targeting criteria is used, they may or may not be achieving the maximum environmental benefits per...
The purpose of this annotated bibliography is to guide middle school and high school students into critical thinking about environmental issues. Through keen observation of their bioregion and through an integration of interdisciplinary literature which focuses on Oregon writers, students will be challenged to think, write, and discuss current issues...
In Prek Toal, a poor subsistence fishing village on Cambodia’s Tonle Sap Lake, the conservation organization Osmose is using ecotourism revenues to finance poverty intervention programs and promote conservation in a threatened ecosystem. This thesis examines local perceptions of tourism as a measure of Osmose’s success. Limited awareness of tourism...
