Atriplex gardneri | |
Atriplex gardneri is a species of flowering plant in the amaranth family known by the common name Gardner's saltbush. It is native to western North America from British Columbia to Saskatchewan in Canada south to Nevada and New Mexico in the United States. [1] The specific epithet of the species, gardneri, is misnamed after its first collector, Alexander Gordon. The naturalist Alfred Moquin-Tandon was under the impression that Gordon's last name was Gardner. [2] [3]
This species is currently considered to be a complex of several varieties and the species is variable in appearance. The varieties can be variable in ploidy level, with diploid, triploid, tetraploid, hexaploid, and others known. [4] Diploid and polyploid individuals may occupy different types of habitat. [1] The varieties intergrade with each other and they can hybridize with each other and with other Atriplex such as Atriplex corrugata . [4]
In general, the plant is a shrub or subshrub growing 10 centimetres (3.9 in) to 1 metre (3.3 ft) in height. The stems may be prostrate or upright. The leaves may be oppositely or alternately arranged and they vary in shape and size. They may be green or grayish green in color. The species can be dioecious or monoecious with male and female flower parts located on separate plants or on the same plant. Flower color can vary across the varieties. [4] The plant produces many seeds. The plant reproduces by seed and by resprouting and layering. [1]
In one treatment, varieties include: [4]
This plant like many other Atriplex is commonly found on salty and alkaline soils. The soils may be clay or sandy. It is a member of several types of saltbush-greasewood plant communities, the two shrub types often occurring together. In some habitats it is a climax species but it also takes hold during secondary succession after a habitat has been disturbed. This species is considered fire-resistant because it is low in flammable oils and high in ash and similar compounds. When it does burn down, the plant grows back quickly by resprouting from its roots. It is sometimes planted in fuelbreaks in California. [1]
The leaves of the plant are a fairly nutritious food source for animals including antelope, some rabbit species, and pronghorn. It is an important source of minimum nutritional requirements for ewes (female sheep) undergoing a gestation period. [1]
This species blooms from May to August.
The Great Basin Desert is part of the Great Basin between the Sierra Nevada and the Wasatch Range. The desert is a geographical region that largely overlaps the Great Basin shrub steppe defined by the World Wildlife Fund, and the Central Basin and Range ecoregion defined by the U.S. Environmental Protection Agency and United States Geological Survey. It is a temperate desert with hot, dry summers and snowy winters. The desert spans large portions of Nevada and Utah, and extends into eastern California. The desert is one of the four biologically defined deserts in North America, in addition to the Mojave, Sonoran, and Chihuahuan Deserts.
Atriplex semibaccata, commonly known as Australian saltbush, berry saltbush, or creeping saltbush, is a species of flowering plant in the family Amaranthaceae and is endemic to Australia. It is a perennial herb native to Western Australia, South Australia, Queensland and New South Wales, but has been introduced into other states and to overseas countries. It flowers and fruits in spring, and propagates from seed when the fruit splits open. This species of saltbush is adapted to inconsistent rainfall, temperature and humidity extremes and to poor soil. It is used for rehabilitation, medicine, as a cover crop and for fodder. Its introduction to other countries has had an environmental and economic impact on them.
Ericameria nauseosa, commonly known as chamisa, rubber rabbitbrush, and gray rabbitbrush, is a shrub in the sunflower family (Aster) found in the arid regions of western North America.
Atriplex hymenelytra, the desert holly, is silvery-whitish-gray shrub in the family Amaranthaceae, native to deserts of the southwestern United States. It is the most drought tolerant saltbush in North America. It can tolerate the hottest and driest sites in Death Valley, and remains active most of the year.
Ericameria cuneata is a species of flowering shrub in the family Asteraceae known by the common name cliff goldenbush. This plant is native to the southwestern United States and northwestern Mexico.
Eriogonum umbellatum is a species of wild buckwheat known by the common name sulphurflower buckwheat, or simply sulphur flower. It is native to western North America from California to Colorado to central Canada, where it is abundant and found in many habitats, including the sagebrush steppe and alpine areas. It is an extremely variable plant and hard to identify because individuals can look very different from one another. Also, there are many varieties. It may be a perennial herb blooming by summer with stems 10 centimeters tall and two to six clusters of flowers, with a whorl of leaves below the stems, or a sprawling shrub approaching two meters high and wide. The leaves are usually woolly and low on the plant, and the flowers come in many colors from white to bright yellow to purple.
Atriplex vesicaria, commonly known as bladder saltbush, is a species of flowering plant of the family Amaranthaceae and is endemic to arid and semi-arid inland regions of Australia. It is an upright or sprawling shrub with scaly leaves and separate male and female plants, the fruit often with a bladder-like appendage.
Caltha leptosepala, the white marsh marigold, twinflowered marsh marigold, or broadleaved marsh marigold, is a perennial species of flowering plant in the buttercup family. It is native to western North America from Alaska to New Mexico, where it grows in wet mountain habitats in alpine and subalpine regions. There are two general wild types of this species, one native to the interior and one that grows along the Pacific coast and coastal mountains, but these are not always treated separately.
The black-tailed jackrabbit, also known as the American desert hare, is a common hare of the western United States and Mexico, where it is found at elevations from sea level up to 10,000 ft (3,000 m). Reaching a length around 2 ft (61 cm), and a weight from 3 to 6 lb, the black-tailed jackrabbit is one of the largest North American hares. Black-tailed jackrabbits occupy mixed shrub-grassland terrains. Their breeding depends on the location; it typically peaks in spring, but may continue all year round in warm climates. Young are born fully furred with eyes open; they are well camouflaged and are mobile within minutes of birth, thus females do not protect or even stay with the young except during nursing. The average litter size is around four, but may be as low as two and as high as seven in warm regions.
