A Vascular Flora Of The South Fork Tule River, Southern Sierra Nevada, Tulare County, California, Jessica M. Orozco
A Vascular Flora Of The South Fork Tule River, Southern Sierra Nevada, Tulare County, California, Jessica M. Orozco
Aliso: A Journal of Systematic and Floristic Botany
I conducted a floristic study of the South Fork Tule River watershed, located in the southern Sierra Nevada in Tulare County, California. The primary objectives of this floristic study were to document and catalogue all vascular plant taxa that occur in the watershed, describe the plant communities, analyze the flora and its affinities with other areas, and establish a herbarium for the Tule River Indian Reservation. The upper reaches of the South Fork Tule River originate on the western slope of Slate Mountain in the Sequoia National Forest and drain west through the Tule River Indian Reservation into Lake Success. …
A Flora Of Coyote Ridge And Flat, Inyo County, California, Martin Purdy
A Flora Of Coyote Ridge And Flat, Inyo County, California, Martin Purdy
CGU Theses & Dissertations
California’s Sierra Nevada mountain range contains a disproportionate share of the state’s plant diversity and is one of the most floristically diverse regions of its size in the United States. The high Sierra Nevada, in particular, has been identified as an important center of species richness and endemism within California. Anthropogenic climate warming is expected to disproportionately affect mountain ecosystems, and models have predicted serious habitat contraction and extirpation for many alpine plant taxa. A specimen-based inventory of the vascular and non-vascular plants of Coyote Ridge and Flat was conducted to establish baseline data for one such sensitive alpine and …
Vascular Flora Of Adobe Valley And Surrounding Hills, Mono County, California, Sophie E. Winitsky
Vascular Flora Of Adobe Valley And Surrounding Hills, Mono County, California, Sophie E. Winitsky
Aliso: A Journal of Systematic and Floristic Botany
Adobe Valley and the Adobe Hills lie east of the Sierra Nevada in Mono County, California, and are within the Great Basin Floristic Province. The flora of Adobe Valley and the surrounding hills is influenced by the Great Basin Desert to the east, the Sierra Nevada to the west and the northern Mojave Desert to the south. Adobe Valley is surrounded by the Adobe Hills, Benton Range and Glass Mountain region, creating a circular closed basin with many small tributaries feeding into it. This topography contributes to the creation of a rare wetland complex, including alkali meadows, marshes, and lakes …
New Additions To The Flora Of San Nicolas Island, Ventura County, California, Benjamin E. Carter, William F. Hoyer Iii, Jonathan Dunn, C. Matt Guilliams
New Additions To The Flora Of San Nicolas Island, Ventura County, California, Benjamin E. Carter, William F. Hoyer Iii, Jonathan Dunn, C. Matt Guilliams
Aliso: A Journal of Systematic and Floristic Botany
Ongoing collecting efforts on San Nicolas Island have substantially increased the number of plant species documented from the island. Here we report thirty-one plants previously unrecorded from the island. The list includes six eudicots, one monocot, four liverworts and twenty mosses. Five of these species are understood to be introduced on San Nicolas and the remainder are believed to be native. The native vascular plants are Logfia filaginoides, Cistanthe maritima and Muhlenbergia microsperma. Of the twenty-four new bryophytes, one—Asterella bolanderi—is the first record from the Channel Islands. Specific ecological and locality information are provided for the …
Vascular Flora Of The Upper Rock Creek Watershed, Eastern Sierra Nevada, California, Joy D. England
Vascular Flora Of The Upper Rock Creek Watershed, Eastern Sierra Nevada, California, Joy D. England
Aliso: A Journal of Systematic and Floristic Botany
The upper Rock Creek watershed is located on the east slope of the Sierra Nevada in Inyo and Mono counties. It is ca. 36.5 square miles (94.5 square km) in area and varies in elevation from 7360 to 13,750 ft (2243 to 4191 m). Quaternary glacial erosion and deposition produced striking landscape features, including alpine fell fields and numerous small lakes. Previous floristic inventories in Rock Creek recorded a combined 396 minimum-rank taxa (species, subspecies, varieties, named hybrids) but were restricted to Little Lakes Valley and the surrounding high areas. An updated, annotated checklist of vascular plants is presented, based …

Aliso: A Journal of Systematic and Floristic Botany
The Sierra San Pedro Mártir (SSPM) is the highest mountain range in Baja California, Mexico, the summit of Picacho del Diablo peak attaining 3095 meters. An annotated checklist describes the vascular flora of the SSPM high country, defined here as above 1800 m. It comprises almost 500 species in 251 genera and 78 families. The high country is dominated by coniferous forest species known from montane California and Arizona whose southern ranges terminate in the SSPM. The annotated checklist identifies 453 species in 236 genera as indigenous, of which 23 species and one variety are endemic to the SSPM. Over …
The Vascular Flora Of The Owens Peak Eastern Watershed, Southern Sierra Nevada, California, Naomi S. Fraga
The Vascular Flora Of The Owens Peak Eastern Watershed, Southern Sierra Nevada, California, Naomi S. Fraga
Aliso: A Journal of Systematic and Floristic Botany
Owens Peak lies at the southern end of the Sierra Nevada within the Bureau of Land Management’s Owens Peak Wilderness Area in Kern County, California. The study site, ca. 50 square miles, encompasses Owens Peak’s eastern watershed, and ranges in elevation from 800–2600 m (2600–8400 ft). Granite rocks of the Sierra Nevada batholith underlie the study area. The eastern watershed of Owens Peak is botanically diverse, with 64 families, 230 genera, and 440 taxa currently documented. Floristic elements within the study area include the southern Sierra Nevada, Great Basin, and Mojave Desert. The flora previously was poorly documented, as discovered …
Distribution Patterns Of Great Basin Conifers: Implications Of Extinction And Immigration, David A. Charlet
Distribution Patterns Of Great Basin Conifers: Implications Of Extinction And Immigration, David A. Charlet
Aliso: A Journal of Systematic and Floristic Botany
Factors influencing the distribution of scattered montane conifers on mountaintops in the Great Basin of North America were investigated. The sources of data were collections and observations on more than 300 mountain ranges in the region. All mountains in the region with at least one montane conifer species and all adjacent source areas were included in the data set. In all, 164 montane island sites and 40 mainland sites were used in the analyses. Physical data for each site were compiled and regression analyses were conducted to test the predictions of three island biogeography models: immigration, extinction, and equilibrium. These …
Vascular Flora Of The Glass Mountain Region, Mono County, California, Michael A. Honer
Vascular Flora Of The Glass Mountain Region, Mono County, California, Michael A. Honer
Aliso: A Journal of Systematic and Floristic Botany
The purpose of this study is to document the vascular flora of the Glass Mountain region of Mono County, California. Little focused botanical attention has been given to this remote volcanic mountain range between the Sierra Nevada and White Mountains of eastern California. The majority of collecting in the area was done from the 1960s through 1998 by Dean W. Taylor, Mary DeDecker, and Jack Reveal, providing good documentation of a few scattered localities of the range. This study circumscribes a large area around the Glass Mountain range, and attempts to catalog the diversity of vascular plants with vouchered collections …
