Graduation date: 2003 / Presentation date: 2002-06-03

This presentation was prepared and given during a meeting in 2004 between the United States Forest Service, Southern Paiute tribal members, and the BARA research team. The power point presents the summary of key findings from the report entitled Puha Flows from It: The Spring Mountains Cultural Landscape Study.

This thesis is the culmination of a graduate research project involving a floristic survey of the lichens of the Spring Mountain National Recreation Area (SMNRA), Humboldt-Toiyabe National Forest, Nevada. The project was based on extensive collections made between 1997 and 2007 as part of an air pollution biomonitoring program and a baseline established by Larry St. Clair (BYU). The Spring Mountains are a sky island mountain range in the Mojave Desert located less than an hour northwest of Las Vegas. A floristic survey of the lichen communities in the Spring Mountains represents a major addition to our understanding of the lichen flora of the Mojave Desert, a poorly studied region in western North America. This thesis also compares the lichen flora of the SMNRA with other lichen floras of the Mojave Desert based on a literature survey of all the lichen studies conducted in the Mojave Desert. The SMNRA species list represents 58% of the 217 species in 68 genera reported for the Mojave Desert. This survey of all reported Mojave lichen species reveals several interesting interactions related to species diversity, substrate, and growth form distribution patterns. These interactions appear to be influenced by two general factors: Microhabitat conditions and available substrates – which are further defined by differences in geological substrates, occurrence and development of woody plant communities, and a combination of environmental factors – elevation, temperature, precipitation, and insolation. Drier and warmer habitats are generally dominated by crustose species with some, mostly smaller, foliose taxa in protected microhabitats usually with shaded or northern exposures. Fruticose species are generally lacking or sparse with smaller thalli when found in hot and dry habitats. All the fruticose species reported from the Mojave Desert sites were rare and had very small thalli. Many foliose and fruticose species, with larger, more complex thalli and thus greater surface area, are more susceptible to higher rates of water loss and therefore occur less frequently in extreme arid locations. The lichen communities in the Mojave Desert respond to sharp contrasts in microhabitat conditions with exposed, lower elevation sites having lower numbers of species along with more drought resistant growth forms – crustose and squamulose species. The Spring Mountains NRA, with high elevation mountains and well developed woody plant communities, accommodates a large variety of microhabitat conditions spread over a complex temperature and moisture gradient. These conditions have resulted in the highest species diversity (124 species in 48 genera) and the greatest number of foliose and corticolous species when compared with all of the other Mojave Desert lichen floras.

Nuwuvi (Southern Paiute) have inhabited the southern Great Basin for thousands of years, and consider Nuvagantu (where snow sits) in the Spring Mountains landscape to be the locus of their creation as a people. Their ancestral territory spans parts of Nevada, Utah, Arizona, and California. My research identifies and describes the heterogeneous character of Nuwuvi ecological knowledge (NEK) of piñon-juniper woodland ecosystems within two federal protected areas (PAs) in southeastern Nevada, the Spring Mountains National Recreation Area (SMNRA) and the Desert National Wildlife Refuge (DNWR), as remembered and practiced to varying degrees by 22 select Nuwuvi knowledge holders. I focus my investigation on four primary aspects of NEK. First, drawing from data obtained through ethnoecological research, I discuss how Nuwuvi ecological knowledge evolved through protracted observation and learning from past resource depletions, and adapted to various environmental and socio-economic drivers of change induced since Euro-American incursion. Second, I argue that Nuwuvi management practices operate largely within a framework of non-equilibrium ecology, marked by low to intermediate disturbances and guided by Nuwuvi conceptions of environmental health and balance. These practices favor landscape heterogeneity and patchiness, and engender ecosystem renewal, expanded ecotones, and increased biodiversity. I then consider the third and fourth aspects of NEK as two case studies that consider NEK at the individual, species, population, habitat, and landscape scales. These case studies operationalize NEK as a relevant body of knowledge and techniques conducive to collaborative resource stewardship initiatives with federal land management agency partners. In the first case study I suggest that the Great Basin piñon pines are Nuwuvi cultural keystone species (CKS), evaluating their central importance to Nuwuvi according to several criteria including number of uses, role in ritual and story, and uniqueness relative to other species. In the second case study I contend that local social institutions regulated Nuwuvi resource use in the past and in some cases continued to do so at the time of study. These local social institutions included a system of resource extraction and habitat entrance taboos that may have mitigated impacts and supported sustainable resource use and conservation. The implications of this research are that Nuwuvi ecological knowledge, disturbance-based adaptive management practices, and resource and habitat taboos are relevant to contemporary land management concerns in piñon-juniper woodlands, offering complementary approaches to adaptive management as practiced in the SMNRA and the DNWR despite divergent epistemological foundations. My research contributed to the Nuwuvi Knowledge-to-Action Project, an applied government-to-government consultation, collaborative resource stewardship, and cultural revitalization project facilitated by The Mountain Institute among seven Nuwuvi Nations, the U.S. Forest Service, and the U.S. Fish and Wildlife Service.

In the arid landscapes of the southern Great Basin and northern Mojave Desert, issues surrounding water resource management are often politically contentious. Nuwuvi (Southern Paiute) have known and managed these resources for thousands of years prior to Euro-American arrival in the region. A variety of factors, including federal policies that resulted in the creation of reservations and forced placement in boarding schools, as well as contemporary resource commodification, have influenced Nuwuvi knowledge and practice. In this thesis, I examined the character of Nuwuvi ethnohydrological knowledge, including management knowledge, of two protected areas: Spring Mountains National Recreation Area (SMNRA), managed by the U.S. Forest Service (USFS) and Desert National Wildlife Refuge (DNWR), managed by the U.S. Fish and Wildlife Service (USFWS). In addition, I investigated perceptions of water health and restoration among participants from the two managing agencies and six Nuwuvi Nations. I addressed these topics using the theoretical framework of political ecology and a methodology that included semi-structured interviews and demographic questionnaires with 16 Nuwuvi knowledge holders and four federal agency participants. I conducted text analysis of partial interview transcripts using the inductive coding method in order to identify recurring themes and concepts related to hydrology, management, and restoration. My results illustrated that Nuwuvi ethnohydrological knowledge, which developed incrementally over time, conceptualized water as a sentient being that required human interaction to remain healthy. There was also evidence that Nuwuvi knowledge of water was changing as a result of political, economic, and social forces. Furthermore, these findings suggest that Nuwuvi and agency approaches to hydrological management and restoration were built upon differing epistemologies, though there was convergence among specific management and restoration techniques. Based on these results, a report of findings from the Nuwuvi Knowledge-to-Action project, including recommendations for collaborative stewardship approaches, was delivered to participants in August 2013.
