"OPTIONS PAPER for the First Peoples' Water Engagement Council (FPWEC)"

"DATED 20 APRIL 2012"

Abstract: This paper highlights the options for a path forward to establish an Indigenous Economic Water Fund (IEWF) through acquisition of water entitlements1 by indigenous people in systems where the consumptive pool is fully allocated. The water allocation that comes from indigenous holdings in the consumptive pool is an important mechanism for enabling Indigenous communities to achieve economic development and as such is a legitimate strategy for ‘Closing the Gap’. …

Indigenous Water Justice Symposium (June 6)

Indigenous peoples throughout the world face diverse and often formidable challenges of what might be termed “water justice.” On one hand, these challenges involve issues of distributional justice that concern Indigenous communities’ relative abilities to access and use water for self-determined purposes. On the other hand, issues of procedural justice are frequently associated with water allocation and management, encompassing fundamental matters like representation within governance entities and participation in decision-making processes. Yet another realm of water justice in which disputes are commonplace relates to the persistence of, and respect afforded to, Indigenous communities’ cultural traditions and values surrounding water—more specifically, …

Croplands are highly productive ecosystems that contribute to land–atmosphere exchange of carbon, energy, and water during their short growing seasons. We evaluated and compared net ecosystem exchange (NEE), latent heat flux (LE), and sensible heat flux (H) simulated by a suite of ecosystem models at five agricultural eddy covariance flux tower sites in the central United States as part of the North American Carbon Program Site Synthesis project. Most of the models overestimated H and underestimated LE during the growing season, leading to overall higher Bowen ratios compared to the observations. Most models systematically under predicted NEE, especially at rain-fed …


Habitat Selection Of Wild Turkeys In Burned Longleaf Pine Savannas, Andrew R. Little, Michael J. Chamberlain, L. Mike Conner, Robert J. Warren Jun 2016

Habitat Selection Of Wild Turkeys In Burned Longleaf Pine Savannas, Andrew R. Little, Michael J. Chamberlain, L. Mike Conner, Robert J. Warren

School of Natural Resources: Faculty Publications

Frequent prescribed fire (≤3 yr) and selective harvest of off-site hardwoods are the primary restoration and management tools for pine (Pinus spp.) savannas in the southeastern United States. However, a knowledge gap exists in our understanding of eastern wild turkey (Meleagris gallopavo silvestris) habitat selection in longleaf pine savannas and research is warranted to direct our future management decisions. Therefore, we investigated habitat selection of female turkeys in 2 longleaf pine savanna systems managed by frequent fire in southwestern Georgia during 2011–2013. We observed differential habitat selection across 2 scales (study area and seasonal area of use) …


Book Reviews: A Chorus Of Cranes: The Cranes Of North America And The World. Paul A. Johnsgard (With Photographs By Thomas D. Mangelsen, And Drawings And Maps By Paul A. Johnsgard)., John G. Sidle Jun 2016

Book Reviews: A Chorus Of Cranes: The Cranes Of North America And The World. Paul A. Johnsgard (With Photographs By Thomas D. Mangelsen, And Drawings And Maps By Paul A. Johnsgard)., John G. Sidle

The Prairie Naturalist

Once again, naturalist and author Paul A. Johnsgard invites us to dance and chorus with cranes, and to appreciate their beauty and links to another species, Homo sapiens. A Chorus of Cranes is about natural history but also is a plea for conservation, which is a common foreword, prologue, preface, and/or epilogue of many wildlife books. It is vintage Paul Johnsgard text from preface to epilogue, words that emerge after a long wade through countless papers and reports, and a prolonged career of observation and reflection in the field. He has beckoned us before to cherish cranes and the natural …


Distribution Of Short-Tailed Shrews (Mammalia: Soricidae: Blarina) In Missouri, Russell S. Pfau, Aaron P. Figueroa Jun 2016

Distribution Of Short-Tailed Shrews (Mammalia: Soricidae: Blarina) In Missouri, Russell S. Pfau, Aaron P. Figueroa

The Prairie Naturalist

Three species of short-tailed shrews (genus Bla- rina) occur throughout the eastern one-half of the United States and southern Canada. B. brevicauda is the most widely distributed, ranging from the Atlantic ocean to the western Great Plains. B. carolinensis occurs throughout the southeastern U.S., and B. hylophaga is found in the southern plains states. The current understanding of the geographic distributions of these species is based primarily on morphol- ogy; size is the primary characteristic used for identifica- tion with B. brevicauda the largest and B. carolinensis the smallest.

The only states in which all three species have been reported …


Resource Selection By Black-Backed Woodpeckers (Picoides Arcticus) And American Three-Toed Woodpeckers (P. Dorsalis) In South Dakota And Wyoming, Sean R. Mohren, Mark A. Rumble, Chadwick P. Lehman, Stanley H. Anderson Jun 2016

Resource Selection By Black-Backed Woodpeckers (Picoides Arcticus) And American Three-Toed Woodpeckers (P. Dorsalis) In South Dakota And Wyoming, Sean R. Mohren, Mark A. Rumble, Chadwick P. Lehman, Stanley H. Anderson

The Prairie Naturalist

Black-backed woodpeckers (Picoides arcticus, [BBWO]) and American three-toed woodpeckers (P. dorsalis, [ATTW]) are uncommon inhabitants of conifer forests and are sympatric in some areas, including the Black Hills. Both species exhibit genetic characteristics associated with isolated populations, are species of special management concern, and for which data are lacking concerning populations and habitats. We developed resource selection models of forest vegetation within 500 m radius plots (78.5 ha) for BBWOs and ATTWs to provide forest managers with stand-level information to estimate how forest management might affect habitat for these species in the Black Hills. Relative probability of selection by BBWOs …


Missing The Point, Christopher N. Jacques Jun 2016

Missing The Point, Christopher N. Jacques

The Prairie Naturalist

Greetings GPNSS members! I hope summer finds you well and enjoying the Great Plains in some way, whether that be getting your hands dirty with field work, a reprieve from the office, anxiously awaiting the crappie bite at your favorite lake, or taking a much needed vacation. For those who enjoy cooler temperatures, summer heat and humidity are challenging and even the most seasoned field biologists among us are tested when fighting the conditions doing what we are passionate about. I personally prefer the fall and winter seasons, though also look forward to summer because it offers me a break …


The Science Of Open Spaces: Theory And Practice For Conserving Large, Complex Systems. Charles G. Curtin., Michelle L. Hellman, Caleb P. Roberts, Hannah Birge, Zachary Warren, Craig R. Allen Jun 2016

The Science Of Open Spaces: Theory And Practice For Conserving Large, Complex Systems. Charles G. Curtin., Michelle L. Hellman, Caleb P. Roberts, Hannah Birge, Zachary Warren, Craig R. Allen

The Prairie Naturalist

The phrase “open spaces,” may bring to mind expansive tracts of prairie, rangeland, or even desert, stretching lonely and unchanged to the horizon. Open spaces also could conjure open oceans or interstitial rural lands between urbanized hubs, dotted with farms, fields, and woodlands. In an abstract sense, open spaces could represent gaps in human understanding or blank spaces on a map. In his book The Science of Open Spaces, landscape ecologist Charles Curtin combines all these perspectives, expanding the definition of “open spaces” to multi-layered and multi-scaled complex systems that are “greater than the sum of their parts.” He populates …


Isotopes From Fecal Material Provides Evidence Of Recent Diet Of Prairie Deer Mice, John W. Doudna, Brent J. Danielson Jun 2016

Isotopes From Fecal Material Provides Evidence Of Recent Diet Of Prairie Deer Mice, John W. Doudna, Brent J. Danielson

The Prairie Naturalist

Prairie deer mice are important predators in many agricultural systems, and through their diet they can help to regulate pest insect and weed populations. Our objective was to test whether fecal material is an effective means of detailing the foraging ecology of small mammals. We conducted three studies to evaluate the efficacy of this technique: 1) field-collected fecal material from unknown deer mice from late winter to early spring, 2) fecal material collected in an enclosure with mice fed a mix of C3 and C4 plant seeds, and 3) fecal material from tagged female mice in the field. We detected …


Book Review: Better Birding: Tips, Tools, And Concepts For The Field. George L. Armistead And Brian L. Sullivan., Stephen J. Dinsmore Jun 2016

Book Review: Better Birding: Tips, Tools, And Concepts For The Field. George L. Armistead And Brian L. Sullivan., Stephen J. Dinsmore

The Prairie Naturalist

George Armistead and Brian Sullivan have written a book whose aim is to provide birders with a solid foundation upon which to develop better birding skills. They advocate a more holistic approach to bird identification than simply looking at a set of predetermined field marks. To that end, their approach combines traditional field identification approaches with behavioral and habitat cues, as well as natural history, to broaden bird identification skills. This is not the first book to make a case for looking at bird identification more broadly, although their specific approach seems unique. The authors offer constructive criticism of “traditional” …


Mink Predation Of Brown Trout In A Black Hills Stream, Jake Davis, Jerry W. Wilhite, Steven R. Chipps Jun 2016

Mink Predation Of Brown Trout In A Black Hills Stream, Jake Davis, Jerry W. Wilhite, Steven R. Chipps

The Prairie Naturalist

In the early 2000’s, declines in the brown trout (Salmo trutta) fishery in Rapid Creek, South Dakota, caused concern for anglers and fisheries managers. We conducted a radio telemetry study in 2010 and 2011 to identify predation mortality associated with mink, using hatchery-reared (2010) or wild (2011) brown trout. Estimated predation rates by mink (Mustela vison) on radio-tagged brown trout were 30% for hatchery fish and 32% for wild fish. Size frequency analysis revealed that the size distribution of brown trout lost to predation was similar to that of other, radio-tagged brown trout. In both years, a higher proportion of …

Climate Ready Boston: Climate Change And Sea Level Rise Projections For Boston, The Boston Research Advisory Group Report, Ellen Douglas, Paul Kirshen, Robyn Hannigan, Rebecca Herst, Avery Palardy

School for the Environment General Publications

This report summarizes the current understanding of the local factors that influence Boston’s future exposure to climate change risks. The following four risk factors were considered most relevant to Boston and are therefore evaluated in this report: sea-level rise, extreme precipitation, coastal storms and extreme temperatures. For each risk factor, a team of scientific experts, comprised of a team leader and three or more team members, was selected to evaluate and summarize the available information contained in both grey (reports, conference proceedings and the like) and peer-reviewed literature. Each team met independently between October 2015 and January 2016, and team …


Fixed Versus Random Sampling Designs In Small South Dakota Glacial Lakes, Bradley J. Smith, Nathan S. Kruger, Nicholas S. Voss, Brian G. Blackwell Jun 2016

Fixed Versus Random Sampling Designs In Small South Dakota Glacial Lakes, Bradley J. Smith, Nathan S. Kruger, Nicholas S. Voss, Brian G. Blackwell

The Prairie Naturalist

Choice of sampling design is fundamental when planning surveys to monitor fisheries resources. However, little is known about the impact that different sampling designs may have on commonly collected fish population metrics used to index relative abundance, size structure, and diversity in small (<200 ha) glacial lakes. To address this issue, we sampled three small glacial lakes in eastern South Dakota with modified fyke nets and gill nets at fixed sites used by South Dakota Game, Fish and Parks and a complement of nets at randomized sites. Catch per unit effort (CPUE), proportional size distribution (PSD), and PSD-preferred (PSD-P) were compared between fixed and random designs for each species and gear by lake while Bray-Curtis distances were calculated between sample designs for each gear type in each lake. Precision of CPUE estimates for routinely indexed species were calculated for both gears used by each sampling design. No consistent bias in calculated population metrics was detected between sampling designs for any species collected with either gear type in the three lakes. Sampling precision of CPUE estimates were low for both gears and study designs; though randomized sites tended to yield lower precision. Power analyses indicated that current levels of sampling effort are insufficient to detect differences in CPUE or PSD/PSD-P between fixed and random sampling designs. In addition to being small, study lakes had relatively homogenous habitat allowing for effective sampling resulting in similar values of CPUE and PSD/PSD-P for both fixed and random study designs, and high assemblage overlap. We conclude that fixed sampling sites provide adequate representation of fish communities in small glacial lakes and are sufficient for monitoring temporal changes in these small, but numerous, systems.


Assessing Genetic Variation Of Rocky Mountain Bighorn Sheep At Elk Mountain, Brynn L. Parr, Rebeca L. Juarez, Jonathan A. Jenks Jun 2016

Assessing Genetic Variation Of Rocky Mountain Bighorn Sheep At Elk Mountain, Brynn L. Parr, Rebeca L. Juarez, Jonathan A. Jenks

The Prairie Naturalist

The bighorn sheep (Ovis canadensis canadensis) herd occupying the Elk Mountain Region of South Dakota and Wyoming was established in 2001 with 20 individuals. An additional 7 ewes were released in 2004. The population increased to approximately 120 individuals in 2009, but subsequently declined to an estimated 80 individuals. Because of the low population size used to establish the herd and relative isolation of the Elk Mountain Region, potential factors associated with the population decline included reduced genetic diversity. Our objectives were to: 1) assess genetic diversity, 2) measure effective population size (Ne), and 3) compare the genetic diversity of …


Keys To Lichens Of North America, Revised And Expand- Ed. Irwin M. Brodo (Photographs By Sylvia Duran Sharnoff And Stephen Sharnoff; Drawings By Susan Laurie-Bourque)., Caleb A. Morse Jun 2016

Keys To Lichens Of North America, Revised And Expand- Ed. Irwin M. Brodo (Photographs By Sylvia Duran Sharnoff And Stephen Sharnoff; Drawings By Susan Laurie-Bourque)., Caleb A. Morse

The Prairie Naturalist

It would be hard to overestimate the importance of the 2001 publication of Lichens of North America (hereafter LNA) by Irwin Brodo, Silvia Duran Sharnoff, and Stephen Sharnoff (Brodo et al. 2001). Beautifully illustrated, LNA included both an excellent overview to lichenology—including such diverse topics as chemistry, ecology, ethnolichenology, and specimen preparation—and descriptions of more than 800 of the common and charismatic lichens of North Ameri- ca. It is the rare book that provides a good introduction to the discipline, while serving as an essential tool for lichenologists. LNA is frequently cited in journals as an authoritative source on spot …


Varmints And Victims: Predator Control In The Ameri- Can West. Frank Van Nuys., Phil Mastrangelo Jun 2016

Varmints And Victims: Predator Control In The Ameri- Can West. Frank Van Nuys., Phil Mastrangelo

The Prairie Naturalist

Having recently retired after 30+ years working in the field of human-wildlife conflicts, including predator conflicts with livestock, I looked forward to reading Varmints and Victims: Predator Control in the American West by Frank Van Nuys. As a wildlife biologist with an interest in the history of wildlife management in North America, I was further intrigued by the subject matter selected by Van Nuys.

In the book’s introduction, Van Nuys explains how the issue of mountain lion (Puma concolor) management in his home state of South Dakota sparked his interest in further exploring the history of predators and their management …


Notes: Comparisons Of Catch Between Two Bait Types With An Emphasis On Pallid Stur- Geon, Thad W. Huenemann, Kirk D. Steffensen Jun 2016

Notes: Comparisons Of Catch Between Two Bait Types With An Emphasis On Pallid Stur- Geon, Thad W. Huenemann, Kirk D. Steffensen

The Prairie Naturalist

Trotline sampling has been a common practice used by commercial and recreational anglers to target specific fish species (e.g. Ictaluridae and Acipenseridae), while biologists have used them as a management tool to monitor and evaluate fish populations (Graham 1997, Vokoun and Rabeni 1999, Arterburn and Berry 2002, Steffensen et al. 2011). Different trotline configurations have been evaluated to determine which combination of hook type and bait produces higher catch rates for catfish species (Johnson 1987, Arterburn and Berry 2002) but this information is lacking for sturgeon species. For example, Arterburn and Berry (2002) concluded that channel catfish (Ictalurus punctatus) were …


Lower Scotts Creek Floodplain And Habitat Enhancement Project, Benjmain O. Cook Jun 2016

Lower Scotts Creek Floodplain And Habitat Enhancement Project, Benjmain O. Cook

Master's Theses

Scotts Creek, located in northern Santa Cruz County, maintains the southernmost persistent population of Central California Coast (CCC) Coho Salmon (endangered) in addition to CCC steelhead (threatened). Fisheries biologists believe overwinter mortality due to lack of refuge habitat is the primary factor limiting salmonid production. Instream rearing habitat may also be limiting, especially during drought years. The legacy effects of historic land use practices, including dredging, wood removal, and the construction of levees, continued to limit refuge and rearing opportunities. A restoration project was implemented to improve refuge and rearing opportunities for salmonids along lower Scotts Creek by removing portions …


Relationships That Extend Beyond The Fence-Line: Private Landowner Attitudes And Interest In Conservation Easements, Ashley Lyn Vizek May 2016

Relationships That Extend Beyond The Fence-Line: Private Landowner Attitudes And Interest In Conservation Easements, Ashley Lyn Vizek

Dissertations and Theses

Private land conservation provides an opportunity to address problems of habitat fragmentation and biodiversity loss caused by an increase in the development and parcelization of private land. Conservation easements (CEs) are an innovative tool used by land trusts to protect significant natural qualities of private land in perpetuity, while also allowing the land to remain in private ownership. Traditionally, property represents an individualistic relationship, however, CEs redefine this relationship by seeking to maximize the overlap in private and public goods in property. In this study, I explore the relationship between the common good and private property through an analysis of …


Assessing Non-Market Benefits Of Seagrass Restoration In The Gulf Of Gdańsk, Tobias Börger, Joanna Piwowarczyk May 2016

Assessing Non-Market Benefits Of Seagrass Restoration In The Gulf Of Gdańsk, Tobias Börger, Joanna Piwowarczyk

Journal of Ocean and Coastal Economics

Seagrass meadows (Zostera marina) are an important ecosystem in the coastal environment of the Baltic Sea. This study employs a discrete choice experiment to value a set of non-market benefits provided by seagrass meadows in the Gulf of Gdańsk, Poland. The benefits valued in this study are a reduction of filamentous algae in the water and on the beach; access to seagrass meadows for boaters and divers; and improved water clarity. Results show significant willingness to pay for each attribute and differences of value estimates across different groups of survey respondents. It is discussed how to link choice …

Forestry and Natural Resources Faculty Publications

Since amphibian declines were first proposed as a global phenomenon over a quarter century ago, the conservation community has made little progress in halting or reversing these trends. The early search for a “smoking gun” was replaced with the expectation that declines are caused by multiple drivers. While field observations and experiments have identified factors leading to increased local extinction risk, evidence for effects of these drivers is lacking at large spatial scales. Here, we use observations of 389 time-series of 83 species and complexes from 61 study areas across North America to test the effects of 4 of the …


Preserving Biodiversity For A Climate Change Future: A Resilience Assessment Of Three Bay Area Species--Adenostoma Fasciculatum (Chamise), Arctostaphylos Canescens (Hoary Manzanita), And Arctostaphylos Virgata (Marin Manzanita), Alison S. Pollack May 2016

Preserving Biodiversity For A Climate Change Future: A Resilience Assessment Of Three Bay Area Species--Adenostoma Fasciculatum (Chamise), Arctostaphylos Canescens (Hoary Manzanita), And Arctostaphylos Virgata (Marin Manzanita), Alison S. Pollack

Master's Projects and Capstones

Anthropogenic climate change is an undeniable threat to the future of the natural world and human civilization. These shifts will have profound impacts on vegetation, especially for species endemic to isolated regions or sensitive to climate change factors. However, species resilience can predict success into the next century. Resilience is defined as the ability to withstand climate change factors, whereas vulnerability is defined as susceptibility to climate induced stress or damage.

Chaparral and coastal scrub ecosystems within the Bay Area of California provide a unique context for examining resilience, as many species are adapted to high temperatures, drought, and wildfire—all …
