AGFD Plant Abstract

Lupinus flavoculatus
TOTAL RANGE:
California (White and Inyo Mountains, eastern Mohave Desert), scattered
throughout southern Nevada, extreme SW Utah, and NW Arizona (Grand Canyon NP and the
Arizona Strip).
RANGE WITHIN ARIZONA:
NW corner of state, Mohave and Coconino counties.
SPECIES BIOLOGY AND POPULATION TRENDS
GROWTH FORM: Low, annual herb.
PHENOLOGY:
Flowering: from April to June, and especially May.
BIOLOGY:
HABITAT:
Mid-elevation desert scrub to pinyon-juniper communities on igneous
and/or limestone gravels. Predominantly a plant of the Mohave Desert and Great Basin of
Nevada and California.
ELEVATION:
Known range in California up to 7215 feet (2200m) and may extend
higher based on specimens currently being reviewed. Arizona collections range from 2785 –
5575 feet (850-1700m).
EXPOSURE:
Usually not specified, although two Arizona collections noted an east
facing exposure.
SUBSTRATE:
Variable. Arizona collections reported volcanic pumice and limestone
gravels, nearly barren balsaltic cinders, and limestone gravels and ledges. One collection
specified a red clay loam soil.
PLANT COMMUNITY:
Communities identified with L. flavoculatus in Arizona range from
pinyon-juniper, blackbrush-yucca-Ambrosia-Atriplex to Larrea (creosote)-mixed desert scrub.
Other plant species listed from Arizona collections sites include: Artemisia tridentata,
Thamnosma montana, Grayia spinosa, Cryptantha angustifolia, Ephedra fasciculate,
Mentzelia multiflora, Brickelia oblongifolia var. linifolia, Yucca baccata, Eriogonum
davidsonii, Ipomopsis polycladon, Lupinus brevicaulis, Cowania and Opuntia.
POPULATION HISTORY AND TRENDS:
Although first collected and identified at the
turn of the century (1909) in Nevada, the species has only been collected in Arizona since
2000. More recent collections (2008) extend the known range about 100km to the southeast,
but there is no data on populations and trends (Christie et al 2011).

SPECIES PROTECTION AND CONSERVATION
ENDANGERED SPECIES ACT STATUS:
None.
STATE STATUS:
None.
OTHER STATUS:
None.
MANAGEMENT FACTORS:
Unknown.
PROTECTIVE MEASURES TAKEN:
None.
SUGGESTED PROJECTS:
Continue to search for species during field expeditions in
NW Arizona to determine if range can be expanded. Collect data on abundance to begin
assessment of populations.
LAND MANAGEMENT/OWNERSHIP: All collections in Arizona have been from USNPS
(Grand Canyon NP) or BLM (Arizona Strip) lands.
