Wet Meadow Plant Associations, Malheur National Wildlife Refuge, Harney County, Oregon, John A. Christy

Institute for Natural Resources Publications

In July 2012, we sampled 131 plots in wet meadow habitat at the southern end of the Malheur National Wildlife Refuge. Analysis of the data identified eleven different plant associations: Alopecurus pratensis, Carex aquatilis var. aquatilis, Carex nebrascensis, Carex pellita, Carex praegracilis, Carex sheldonii, Distichlis spicata, Juncus balticus, Leymus triticoides, Phalaris arundinacea, and Sparganium eurycarpum. Plant associations spanned a wetland gradient from seasonally moist to seasonally or perennially flooded, but surface water had left most stands at time of sampling. Mean Wetland Indicator Status scores help to place the plant associations within gradients in soil moisture and alkalinity. The Alopecurus …

Evaluating The Utility Of Beaver Reintroduction Programs For Enhancing Habitat For Rainbow Trout And Steelhead, Jonathan Rodger Hegna

All Master's Theses

Beaver reintroduction programs are increasingly being viewed as a way to enhance salmonid habitat and production. However, the actual effectiveness of using beavers as a habitat enhancement tool for ESA listed steelhead Oncorhynchus mykiss populations is unknown. We examined the type of habitat, at both the microhabitat and mesohabitat levels, preferred by steelhead in three small streams in the upper Yakima Basin, WA through standard snorkel surveys and habitat measurements. Our results suggest that steelhead in small streams strongly prefer (relative to availability) microhabitats that have deeper water(> 30 cm), slow stream velocities(< 0 .05 mis), and complex cover types. Habitat partitioning among the size-classes (small< 50 mm, medium 50-90 mm, large> 90 mm total length, TL) principally operated …

The Elwha River Restoration: Landscape Change, Salmon, And Sense Of Place, Kelseyanne Johnson

All Master's Theses

Removal of the Elwha River dams to restore the ecosystem and salmon fisheries is the largest project of its kind in the history of the United States. Spanning decades and affecting generations, this project has changed and will continue to change the landscape. This research examined the influence of the anticipated return of salmon on 18 key stakeholders' sense of place of the Elwha River. For almost all stakeholders, changes to the Elwha landscape are welcomed as they expect that salmon will restore the ecosystem to its natural state. Narrative data revealed dominant themes in participants' sense of place expressed …

Spatial And Temporal Patterns In Ungulate-Ecosystem Interactions, Bryan D. Murray

Dissertations, Master's Theses and Master's Reports - Open

Ungulates are important components of a variety of ecosystems worldwide. This dissertation integrates aspects of ungulate and forest ecology to increase our understanding of how they work together in ways that are of interest to natural resource managers, educators, and those who are simply curious about nature. Although animal ecology and ecosystem ecology are often studied separately, one of the general goals of this dissertation is to examine how they interact across spatial and temporal scales. Forest ecosystems are heterogeneous across a range of scales. Spatial and temporal habitat use patterns of forest ungulates tend to be congregated in patches …

Acequias, Brigette Buynak, Jerold Widdison, Darcy S. Bushnell

Water Matters!

Acequias are community irrigation systems in the villages and pueblos of New Mexico. They have deep roots in two ancient traditions—Pueblo Indian and Spanish. The Pueblos collected and shared water for centuries before the arrival of Spanish colonists in 1598. The Spanish settlers brought technical knowledge and institutional frameworks for governing irrigation systems, which originated in the Moors’ seven-century occupation of Spain. Both traditions remain important to an understanding of New Mexico’s acequia heritage and the continuing relevance of these “water democracies.”Today, these traditions must meld with state law as the legislature has provided that acequias are “political subdivisions” or …

American Indian Water Rights, Michael Osborn, Darcy S. Bushnell

Water Matters!

Pueblos and tribal reservations are located within most of the larger stream systems in New Mexico. Each has claims to rights to use the water in its stream. In New Mexico, Indian rights are significant because of their early priority dates, because of the large amounts of water rights claimed, or both. In some instances, such claims have the potential to displace a significant number of junior water rights.

Common law theories or doctrines pertaining to Indians continue to be judicially refined and to evolve so that discussing the nature and extent of “Indian water rights” is a complex topic.

Groundwater, Darcy S. Bushnell, Diego Urbina

Water Matters!

Since the late nineteenth century, New Mexicans have been developing the state’s groundwater resources. From hand-dug wells to proposed wells that could penetrate to 12,000 feet, residents have sought sources to supplement and replace surface water. The state relies upon groundwater to supply almost 50 percent of its needs.

As the population grows and drought intensifies, groundwater sources are tapped with increasing urgency. Limited steps are being taken to preserve groundwater through conservation, groundwater recharge, and regulation.

State And Regional Water Planning, Brigette Buynak, Susan Kelly, Sarah Armstrong

Water Matters!

A statewide water planning effort was initiated by the New Mexico legislature in the 2003 session. The Interstate Stream Commission (ISC),in collaboration with the Office of the State Engineer (OSE) and the Water Trust Board, was tasked with preparing and implementing a comprehensive state water plan. Regional water planning had begun much earlier, prompted by a lawsuit that El Paso filed against New Mexico in 1983, El Paso v. Reynolds.

The State Water Plan Act of 2003 (Act) was intended to promote stewardship of the state’s water resources and to establish clear policies and strategies for management of the state’s …

Community Water Systems, Joanne Hilton, Susan Kelly, Sarah Armstrong

Water Matters!

Apart from the major cities along the Rio Grande corridor, much of New Mexico remains relatively rural. Recent studies estimate a 2013population of around 2,085,500 statewide. In the state fiscal year 2011,about 1,836,000 people, or 88 percent of New Mexico’s population obtain their water from community water systems. Approximately 284,000 people, or about14 percent of the population, receive their drinking water from community water systems serving fewer than 5,000 people. As of 2012, there are 1,148 public water systems that provide drinking water in New Mexico. Of these systems, 593are community water systems; of these, 546 serve fewer than 5,000 …

Deep Water Regulation, Paul Bossert, Kari Olson

Water Matters!

With most of the surface water in New Mexico fully appropriated and with groundwater sources being drawn down and becoming less reliable, the search for new sources of water is reaching further and further afield of traditional sources and methods. Water wells deeper than 2,000 feet have been rare due to the expense of deep drilling and the uncertainty of finding potable water. Yet the combined circumstances of advances in hydrology and the escalating demand for new water have driven the search for water deeper than was previously considered practical.

Water Marketing, Jeremy Oat, Laura Paskus

Water Matters!

Water doesn’t just flow around New Mexico in streams and rivers: it also moves around on paper. Since all of the state’s surface-water and most of its groundwater have already been allocated, the only way for cities, developers, or conservation organizations to find new water supplies is to buy and transfer water rights from old uses and places to new uses and places. The N.M. Office of the State Engineer (OSE) approves each of these transfers, most of which are relatively small, but the numbers can add up over time. Between 1982 and 2011, for instance, 21,000 acre-feet of Middle …

Water Quality Regulation, Joanne Hilton, Susan Kelly, James Hogan, Kimberly Kirby, Jerry Schoeppner

Water Matters!

While many of the water issues in New Mexico center around having an adequate supply of water, the quality of the water is just as important as the quantity in supplying water for drinking and other uses that rely on clean water. Protecting water quality is financially more feasible than conducting expensive cleanup programs. New Mexico has a strong interest in water quality regulation to protect public health and the environment and to minimize expenditures for mitigation of contaminated supplies. Water quality is a difficult subject to navigate; there is a complex web of statutes and agency involvement. This paper …

Water Litigation In The Lower Rio Grande, Darcy S. Bushnell

Water Matters!

The water allocation issues are hotly contested in south-central New Mexico and the surrounding area. Today, the river and those who depend on it face more administrative challenges in the face of shrinking water supplies and increased population. These challenges have given rise to two ongoing lawsuits: the Lower Rio Grande Adjudication,New Mexico v. EBID, et al., 96-CV-888 (1996) (N.M. v. EBID) in the New Mexico Third Judicial District Court (adjudication court) and the New Mexico v. United States,et al., D.N.M. 11-CV-691 (2011) (N.M. v.U.S.) in United States District Court of New Mexico (U.S. District Court).

Eastern New Mexico Rural Water System (Ute Pipeline Project), Jerold Widdison, Paul Van Gulick, Darcy S. Bushnell

Water Matters!

The Ute Pipeline Project (Project), officially known as the Eastern New Mexico Rural Water System (ENMRWS),is a 151-mile-long pipeline project to provide a sustainable municipal and industrial water supply for several eastern New Mexico communities and a military base. The Congress authorized major federal funding for the Ute Pipeline in the Omnibus Public Land Management Act of 2009. This important milestone for the project was reached after about 45 years of effort.Attention now shifts to myriad details involved in actually constructing, financing,and administering the project.

The Rio Grande As An International River, Margaret J. Vick

Water Matters!

The Rio Grande is divided into two major river reaches and has different legal regimes for each. New Mexico is primarily concerned with the Rio Grande from the headwaters in Colorado to Ft. Quitman in Texas, a distance of approximately 670 miles. This section of the river is the subject of the1906 Rio Grande Convention (Treaty) between the United States and Mexico. The lower section of the Rio Grande from Ft. Quitman to the Gulf of Mexico is the subject of the 1944 Rivers Treaty between the United States and Mexico; the 1944 Rivers Treaty also includes the Colorado and …

Improving Model Performance For Invasive Plant Species Distribution Using Global-Scale Presence-Only Data: Parameterization And Data Quality, Feng Yu

Open Access Theses

Invasive species have significant ecological and economic impacts. To control species' invasion, risk assessment provides the most essential information for identification and evaluation of the potential risk of the invasive species, especially in their early invasion stages. Species distribution models (SDMs) is the foundation for risk assessment, in terms of both the practical and theoretical interest in our understanding of species invasion process. SDMs contribute to the proactive invasion management and the test of ecological or biogeographical hypotheses about species distributions in relation to their environment.

However, modeling of invasive species at large spatial scale (i.e., cross-continental) is rarely discussed. …

Factors Influencing The Establishment And Survival Of Native Hardwood Tree Seedlings Of The Kentucky Inner Bluegrass Blue Ash-Oak Savanna-Woodland, James D. Shaffer

Theses and Dissertations--Biology

Historically, the Kentucky Inner Bluegrass blue ash-oak savanna-woodland was the primary ecosystem of the Inner Bluegrass Region (IBR) of Kentucky. After European settlement, the majority (>99%) of Bluegrass savanna was converted to agricultural and urban land uses. Currently remnant savanna tree species are failing to recruit. Therefore, a long-term restoration ecology project researching competition and disturbance on seedling establishment, survival, and growth has been established at Griffith Woods (the largest remaining savanna in Kentucky) in Harrison Co., KY. Fourteen native hardwood tree species (a total of 6,168 seedlings) have been experimentally planted. Light, soil, surrounding vegetation, and herbivory, factors …
