Oak Canyon Nature Center
Oak Canyon Nature Center is a nature preserve located in Anaheim, California, Anaheim, Southern California. Owned by the city, the park spans an area of 58-acres (23 hectares), comprising three adjoining canyons of the Santa Ana foothills. It has an elevation range from 525 to 825 feet (160 to 251 m)., and contains three major vegetation zones: coastal sage scrub, California oak woodland, oak woodland and Riparian zone, riparian. Open on weekends, the John J. Collier Interpretive Center features a museum with live animal and regional natural history exhibits. The center offers nature education programs and summer camp programs. Ecology Precipitation The annual precipitation average per rainfall year (July 1 to June 30) within a 20-year period between 1982 and 2002. Most of the precipitation occurs during the November–April rainy season. Vegetation The Oak Canyon ridge is covered in oak woodland on its northern side and coastal sage scrub habitat on its southern side. Due to t ...

Oak Canyon Nature Center Interpretive Center
An oak is a tree or shrub in the genus ''Quercus'' (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably ''Lithocarpus'' (stone oaks), as well as in those of unrelated species such as ''Grevillea robusta'' (silky oaks) and the Casuarinaceae (she-oaks). The genus ''Quercus'' is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from temperateness, cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America has the largest number of oak species, with approximately 160 species in Mexico of which 109 are endemic and about 90 in the United States. The second greatest area of oak diversity is China, with approximately 100 species. Description Oaks have spirally arranged Leaf, leaves, with Dentate leaf, lobate margins in many species; some have serrated leaves or enti ...

Eriogonum Fasciculatum
''Eriogonum fasciculatum'' is a species of wild buckwheat known by the common names California buckwheat and flat-topped buckwheat. Characterized by small, white and pink flower clusters that give off a cottony effect, this species grows variably from a patchy mat to a wide shrub, with the flowers turning a rusty color after blooming. This plant is of great benefit across its various habitats, providing an important food resource for a diversity of insect and mammal species. It also provides numerous ecosystem services for humans, including erosion control, post-fire mitigation, increases in crop yields when planted in hedgerows, and high habitat restoration value.Montalvo, A.

Geography Of Anaheim, California
Anaheim ( ) is a city in northern Orange County, California, part of the Los Angeles metropolitan area. As of the 2020 United States Census, the city had a population of 346,824, making it the most populous city in Orange County, the 10th-most populous city in California, and the 56th-most populous city in the United States. Anaheim is the second-largest city in Orange County in terms of land area, and is known for being the home of the Disneyland Resort, the Anaheim Convention Center, and two major sports teams: the Los Angeles Angels baseball team and the Anaheim Ducks ice hockey club. Anaheim was founded by fifty German families in 1857 and incorporated as the second city in Los Angeles County on March 18, 1876; Orange County was split off from Los Angeles County in 1889. Anaheim remained largely an agricultural community until Disneyland opened in 1955. This led to the construction of several hotels and motels around the area, and residential districts in Anaheim soon fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nature Centers In California
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Protected Areas Of Orange County, California
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servin ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrophyte
Pyrophytes are plants which have adapted to tolerate fire. Fire acts favourably for some species. "Passive pyrophytes" resist the effects of fire, particularly when it passes over quickly, and hence can out-compete less resistant plants, which are damaged. "Active pyrophytes" have a similar competing advantage to passive pyrophytes, but they also contain volatile oils and hence encourage the incidence of fires which are beneficial to them. "Pyrophile" plants are plants which require fire in order to complete their cycle of reproduction. Passive pyrophytes These resist fire with adaptations including thick bark, tissue with high moisture content, or underground storage structures. Examples include: * Longleaf pine (''Pinus palustris'') * Giant sequoia (''Sequoiadendron giganteum'') * Coast redwood (''Sequoia sempervirens'') * Cork oak (''Quercus suber'') * Niaouli (''Melaleuca quinquenervia'') which is extending in areas where bush fires are a mode of clearing (e.g. New Caledoni ...

Xerophyte
A xerophyte (from Ancient Greek language, Greek ξηρός ''xeros'' 'dry' + φυτόν ''phuton'' 'plant') is a species of plant that has adaptations to survive in an environment with little liquid water, such as a desert such as the Sahara or places in the Alps or the Arctic. Popular examples of xerophytes are cactus, cacti, pineapple and some Gymnosperm, Gymnosperm plants. The structural features (morphology (biology), morphology) and fundamental chemical processes (physiology) of xerophytes are variously adapted to conserve water, also common to store large quantities of water, during dry periods. Other species are able to survive long periods of extreme dryness or desiccation of their Tissue (biology)#Plant tissue, tissues, during which their metabolism, metabolic activity may effectively shut down. Plants with such morphological and physiological adaptations are .” Xeromorphic”, The Cambridge Illustrated Glossary of Botanical Terms, Michael Hickey, Clive King, Cambridge U ...
