Forb INFORMATION AVAILABLE:
In October of 2012 an extensive search was done to locate information on Cushenbury milkvetch (see FEIS's list of source literature), with few results. The following paragraphs provide details of the available information.
DISTRIBUTION AND OCCURRENCE SPECIES: Astragalus albens GENERAL DISTRIBUTION:
Cushenbury milkvetch is endemic to the northeastern San Bernardino Mountains [9,12,16]. It is known from fewer than 33 occurrences from Furnace Canyon southeast to the head of Lone Valley, a range of 15 miles (24 km) [16]. In 1992, Cushenbury milkvetch populations were estimated at 5,000 to 10,000 individuals [16,17].

Distribution of Cushenbury milkvetch. Map courtesy of the Jepson Herbarium [11]. States [14]:
CA SITE CHARACTERISTICS:
Cushenbury milkvetch occurs on gentle, rocky slopes and canyon washes composed of limestone and dolomite (carbonate) soils at elevations of 5,000 to 6,600 feet (1,500-2,000 m) [6,16,17]. A few occurrences are found below 5,000 feet in rocky drainages that receive limestone outwash from higher drainages [17]. Populations of Cushenbury milkvetch have also been documented on granitic soils [12,16]. Cushenbury milkvetch prefers an open canopy, rock cover greater than 75%, and 21.3% calcium [3,6] and little accumulation of organic material [3,6,16,17] in the soil.

PLANT COMMUNITIES:
Cushenbury milkvetch grows in Joshua tree (Yucca brevifolia) woodland, singleleaf pinyon-Utah juniper (Pinus monophylla-Juniperus osteosperma) woodland, and Mojavean desert scrub [2,12]. Plant species commonly associated with Cushenbury milkvetch plants in the carbonate habitats are Utah juniper, singleleaf pinyon, Joshua tree, curlleaf mountain-mahogany (Cercocarpus ledifolius), blackbrush (Coleogyne ramosissima), Mojave mound cactus (Echinocereus mojavensis), desert almond (Prunus fasciculata), Mojave yucca (Yucca schidigera), sand dropseed (Sporobolus cryptandrus), and desert needlegrass (Achnatherum speciosum) [3]. Cushenbury milkvetch often occurs with 2 other federally listed species, Cushenbury buckwheat (Eriogonum ovalifolium var. vineum) and Parish’s daisy (Erigeron parishii) [16].

Astragalus albens ( الإنجليزية )

المقدمة من wikipedia EN

Astragalus albens is a species of milkvetch known by the common names Cushenbury milkvetch and silvery-white milkvetch.

Distribution

It is endemic to San Bernardino County, California, where it is known from the northern slopes of the San Bernardino Mountains near the settlement of Cushenbury. Most of the plants are located in the woodland and scrub of the slopes between Big Bear in the mountains and Lucerne Valley in the Mojave Desert at the foot of the range.

It grows in habitat rich in carbonate rock. It is a federally listed endangered species which is known from 30 to 50 populations.[1] There are a total of about 7000 plants, fewer in drought years.[2]

Description

Astragalus albens is an annual or perennial herb producing a prostrate mat of delicate stems coated densely in silvery hairs. The leaves are generally a few centimeters long and made up of several gray-green oval-shaped leaflets less than a centimeter long each. The inflorescence arises upright from the low patch of foliage and bears up to 14 pealike flowers. Each flower is dark-veined light to deep purple with a spot of white or light pink in the throat.

The fruit is a legume pod between one and two centimeters long. It is roughly hairy and crescent-shaped, drying to a thick papery texture.[3]

Conservation

The main threat to this species is limestone mining, a large industry in this part of the San Bernardino Mountains. This form of mining alters the local habitat by physically removing plant life for quarries, road construction, and load dumping. It also produces major changes in the hydrology of the area and releases large amounts of carbonate dust into the air which combines with water and forms a very thin layer of what is essentially cement over the habitat.[1] Most of the populations of this plant are located on sites of active mining or sites which are targeted for mining in the future.[1]

Most of these sites are part of San Bernardino National Forest, and there are plans to set aside pieces of habitat for this and other endemics. Other threats to the species include off-road vehicle use and urban development.

Astragalus albens ( الإسبانية، القشتالية )

المقدمة من wikipedia ES

Astragalus albens es una especie de planta herbácea perteneciente a la familia de las leguminosas. Es originaria de Norteamérica.

 src=
Vista de la planta

Distribución

Es endémica del Condado de San Bernardino, California , donde se conoce en la vertiente norte de las Montañas de San Bernardino. La mayoría de las plantas se encuentran en los bosques y matorrales de las laderas entre Big Bear, en las montañas y el valle de Lucerna en el desierto de Mojave, al pie de la cordillera. Crece en hábitats de rocas ricas en carbonato. Se encuentra en una lista federal de especies en peligro de extinción, ya que solo se conoce 30 a 50 poblaciones.[1]​ Hay un total de cerca de 7.000 plantas, menos en años de sequía.[2]

Descripción

Es una planta herbácea anual o perenne, produciendo una alfombra de delicados tallos postrados, densamente cubiertos de pelos plateados. Las hojas son, por lo general, de unos pocos centímetros de largo y constan de varios foliolos en forma de óvalo, son de color verde-gris y menos de un centímetro de largo cada uno. La inflorescencia se presenta en posición vertical desde la parte baja del follaje y lleva hasta 14 flores. Cada flor es de color morado oscuro con una mancha de color blanco o rosa pálido en la garganta. El fruto es una legumbre en forma de vaina de entre uno y dos centímetros de largo. Es más o menos peludo y con forma de media luna, secado tiene una textura parecida al papel grueso.

Conservación

La principal amenaza para esta especie es la minería de piedra caliza, que es una gran industria en esta parte de las montañas de San Bernardino. Esta forma de minería altera el hábitat local, la eliminación física de vida de las plantas de las canteras, la construcción de carreteras y el vertido de carga. También produce grandes cambios en la hidrología de la zona y libera grandes cantidades de polvo de carbonato en el aire que se combina con agua y forma una fina capa de lo que es esencialmente cemento sobre el hábitat.[1]​ La mayoría de las poblaciones de esta planta se encuentran en los sitios de la actividad minera o sitios que están señalados para la minería en el futuro.[1]​ La mayoría de estos sitios son parte del Bosque Nacional San Bernardino, y hay planes para dejar de lado las plantas del hábitat y otras especies endémicas de este. Otras amenazas para la especie son el uso de todoterrenos y el desarrollo urbano .

Taxonomía

Astragalus albens fue descrita por Edward Lee Greene y publicado en Bulletin of the California Academy of Sciences 1(3): 156. 1885.[3]

Etimología

Astragalus: nombre genérico derivado del griego clásico άστράγαλος y luego del Latín astrăgălus aplicado ya en la antigüedad, entre otras cosas, a algunas plantas de la familia Fabaceae, debido a la forma cúbica de sus semillas parecidas a un hueso del pie.[4]

albens: epíteto latino que significa "blanquecino".[5]
