Southern California Walnut
''Juglans californica'', the California black walnut, also called the California walnut, or the Southern California black walnut, is a large shrub or small tree (about ) of the walnut family, Juglandaceae, endemic to the Central Valley and the Coast Range valleys from Northern to Southern California. Distribution ''Juglans californica'' is generally found in the valleys and adjacent slopes of the California Coast Ranges, Transverse Ranges, and Peninsular Ranges. It grows as part of mixed woodlands, and also on slopes and in valleys wherever conditions are favorable. It is threatened by development and overgrazing. Some native stands remain in urban Los Angeles in the Santa Monica Mountains, Hollywood Hills, and Repetto Hills. ''J. californica'' grows in riparian woodlands, either in single species stands or mixed with California's oaks (''Quercus'' spp.) and cottonwoods (''Populus fremontii''). Climate model predictions indicate that *Juglans californica* may expand its range no ...

Sereno Watson
Sereno Watson (December 1, 1826 – March 9, 1892) was an American botanist. Life Watson was born on December 1, 1826, in East Windsor Hill, Connecticut. Graduating from Yale in 1847 in biology, he drifted through various occupations until, in California, he joined the Clarence King Expedition and eventually became its expedition botanist. Appointed by Asa Gray as assistant in the Gray Herbarium of Harvard University in 1873, he later became its curator, a position he maintained until his death. Watson was elected a Fellow of the American Academy of Arts and Sciences in 1874, and a member of the National Academy of Sciences in 1889.

Chumash (tribe)
The Chumash are a Native American people of the central and southern coastal regions of California, in portions of what is now Kern, San Luis Obispo, Santa Barbara, Ventura and Los Angeles counties, extending from Morro Bay in the north to Malibu in the south to Mt Pinos in the east. Their territory includes three of the Channel Islands: Santa Cruz, Santa Rosa, and San Miguel; the smaller island of Anacapa was likely inhabited seasonally due to the lack of a consistent water source. Modern place names with Chumash origins include Malibu, Nipomo, Lompoc, Ojai, Pismo Beach, Point Mugu, Port Hueneme, Piru, Lake Castaic, Saticoy, Simi Valley, and Somis. Archaeological research shows that the Chumash people have deep roots in the Santa Barbara Channel area and have lived along the southern California coast for millennia. History Prior to European contact (pre-1542) Indigenous peoples have lived along the California coast for at least 11,000 years. Sites of the M ...

Natural History Of The California Coast Ranges
Nature is an inherent character or constitution, particularly of the ecosphere or the universe as a whole. In this general sense nature refers to the laws, elements and phenomena of the physical world, including life. Although humans are part of nature, human activity or humans as a whole are often described as at times at odds, or outright separate and even superior to nature. During the advent of modern scientific method in the last several centuries, nature became the passive reality, organized and moved by divine laws. With the Industrial Revolution, nature increasingly became seen as the part of reality deprived from intentional intervention: it was hence considered as sacred by some traditions ( Rousseau, American transcendentalism) or a mere decorum for divine providence or human history (Hegel, Marx). However, a vitalist vision of nature, closer to the pre-Socratic one, got reborn at the same time, especially after Charles Darwin. Within the various uses of the word ...

Trees Of Northern America
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear o ...

Endemic Flora Of California
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomi ...

Juglans
Walnut trees are any species of tree in the plant genus ''Juglans'', the type genus of the family (biology), family Juglandaceae, the seeds of which are referred to as walnuts. All species are deciduous trees, tall, with pinnate leaves , with 5–25 leaflets; the shoots have chambered pith, a character shared with the wingnut (plant), wingnuts (''Pterocarya''), but not the hickory, hickories (''Carya'') in the same family. The 21 species in the genus range across the north temperate Old World from southeast Europe east to Japan, and more widely in the New World from southeast Canada west to California and south to Argentina. Edible walnuts, which are consumed worldwide, are usually harvested from cultivated varieties of the species ''Juglans regia''. China produces half of the world total of walnuts. Etymology The common name ''walnut'' derives from Old English language, Old English ''wealhhnutu'', literally 'foreign nut' (from ''wealh'' 'foreign' + ''hnutu'' 'nut'), because ...

Juglans Hindsii
''Juglans hindsii'', commonly called the Northern California black walnut and Hinds's black walnut, is a species of walnut tree native to the western United States (California and Oregon). It is commonly called claro walnut by the lumber industry and woodworkers, and is the subject of some confusion over its being used as rootstock for English walnut. Description ''Juglans hindsii'' is a large tree that grows up to tall and may reach over with enough shade. The species normally has a single erect trunk, commonly without branches in the lower half of the tree, and a crown that can be wider than the tree is tall. Trunks may reach in diameter near the base of the tree. The leaf is approximately long, with 13–21 leaflets per leaf, each long, with dentate margins. The vein axils bear tufts of hair underneath, differentiating the species from the Southern California walnut. The species is monoecious, with male flowers in yellow-green catkins up to long and females stemming ...

California Native Plant Society
The California Native Plant Society (CNPS) is a California environmental non-profit organization (501(c)(3)) that seeks to increase understanding of California's native flora and to preserve it for future generations. The mission of CNPS is to conserve California native plants and their natural habitats, and increase understanding, appreciation, and horticultural use of native plants throughout the entire state and the California Floristic Province. History California Native Plant Society was founded in 1965 by professional botanists and grassroots activists who, after saving an important native plant garden in Berkeley's Tilden Regional Park, were inspired to create an ongoing organization with the mission to save and promote the native plants of California. Structure For 50 years, professional CNPS staff and volunteers have worked alongside scientists, government officials, and regional planners to protect habitats and species, and to advocate for well-informed environmental ...

Natural Landscaping
Natural landscaping, also called native gardening, is the use of native plants including trees, shrubs, groundcover, and grasses which are local to the geographic area of the garden. Benefits Maintenance Natural landscaping is adapted to the climate, geography and hydrology and should require no pesticides, fertilizers and watering to maintain, given that native plants have adapted and evolved to local conditions over thousands of years. However, these applications may be necessary for some preventive care of trees and other vegetation. Native plants suit today's interest in "low-maintenance" gardening and landscaping, with many species vigorous and hardy and able to survive winter cold and summer heat. Once established, they can flourish without irrigation or fertilization, and are resistant to most pests and diseases. Many municipalities have quickly recognized the benefits of natural landscaping due to municipal budget constraints and reductions and the general public ...

Backyard Wildlife Habitat
The Backyard Wildlife Habitat is a program of the National Wildlife Federation that encourages homeowners in the United States to manage their gardens and yards as a wildlife garden, with the goal of maintaining healthy and diverse animal habitats and ecosystems. The program began in 1973. By 1998, it had impacted more than 21,000 yards and, as of 2006, has certified over 60,000 'backyards'. Certification To be a certified Backyard Wildlife Habitat, a garden or yard, or any outdoor space from a balcony up to a multi-acre tract of land, must offer food, water, shelter, and a place for raising young to beneficial insects or animals. Over time the Federation has introduced variants or expansions of the program for schoolyards and for communities. In order for a backyard to be certified as a Backyard Wildlife Habitat by the National Wildlife Federation, the space must do all of the following: provide food, water, cover, a place to raise young, and be maintained in a way that has a ...

Xeriscaping
Xeriscaping is the process of Garden design, landscaping, or gardening, that reduces or eliminates the need for irrigation. It is promoted in regions that do not have accessible, plentiful, or reliable supplies of fresh water and has gained acceptance in other regions as access to irrigation water has become limited, though it is not limited to such climates. Xeriscaping may be an alternative to various types of traditional gardening. In some areas, terms such as ''water conservation, water-conserving landscaping'', ''drought-tolerant landscaping'', and ''smart scaping'' are used instead. The use of plants whose natural requirements are appropriate to the local climate is emphasized, and care is taken to avoid losing water to evaporation and surface runoff, runoff. However, the specific plants used in xeriscaping vary based on climate as this strategy can be used in xeric, mesic, and hydric environments. Xeriscaping is different from natural landscaping, because the emphasis in x ...
