DISTRIBUTION AND OCCURRENCE
SPECIES: Lycium pallidum | Pale Wolfberry
GENERAL DISTRIBUTION :
Pale wolfberry ranges from southern Colorado, Utah, and Nevada south to
California, Arizona, New Mexico, and western Texas [23,33,43,47]. The
typical variety apparently has a more southernly distribution than L.
pallidum var. oligospermum, which is found in the Mohave Desert and the
northern Sonoran Desert in California [20,31,33,43]. Pale wolfberry is
also found in Mexico in Sonora, Chihuahua, Zacatecas, and San Luis

HABITAT TYPES AND PLANT COMMUNITIES :
Pale wolfberry is characteristic of Mohave Desert vegetation and, in
addition to species already mentioned, is associated in that region with
winterfat (Ceratoides lanata), range ratany (Krameria parvifolia),
ephedra (Ephedra spp.), spiny hopsage (Grayia spinosa), Schockley
goldenhead (Acamptopappus schockleyi), Fremont dalea (Dalea fremontii),
spiny menodora (Menodora spinescens), prickly pear (Opuntia spp.), and
yucca (Yucca spp.) [1,5,8,29,40,44].
Pale wolfberry is also found throughout the Sonoran and Chihuahuan
deserts and is associated with species including ocotillo (Fouquieria
splendens), ironwood (Olneya tesota), saguaro (Carnegiea gigantea),
false-mesquite (Calliandra eriophylla), feather dalea (Dalea formosa),
brittle bush (Encelia farinosa), leatherstem (Jatropha dioica), yucca,
agave (Agave spp.), prickly pear and cholla (Opuntia spp.), and catclaw
(Acacia spp.) [9,19,32].
Pale wolfberry sometimes occurs in riparian woodlands such as those in
the Rincon Mountains of Arizona. In these habitats it is associated
with species such as sycamore (Platanus wrightii), willow (Salix spp.),
Arizona walnut (Juglans major), Fremont cottonwood (Populus fremontii),
alligator juniper (Juniperus deppeana), Arizona white oak (Quercus
arizonica), and velvet ash (Fraxinus velutina) [7].
Pale wolfberry is not listed as a dominant or codominant shrub species
in available publications.
VALUE AND USE
SPECIES: Lycium pallidum | Pale Wolfberry
WOOD PRODUCTS VALUE :
NO-ENTRY
IMPORTANCE TO LIVESTOCK AND WILDLIFE :
Pale wolfberry fruits are consumed by birds and some rodents [24,26,33],
and its foliage may be browsed by livestock [23,24,33,42,43]. It is
little used by big game, however [26].
Pale wolfberry is an important postnesting food for phainopepla in the
Colorado River Valley. The spring phainopepla diet consists mainly
of pale wolfberry fruits and insects [4].
Shrub-grasslands, in which pale wolfberry occurs, are preferred habitat
of coyotes at the Pinon Canyon Maneuver Site in southeastern Colorado
[16].
Woodrats in the Mohave Desert of California select pale wolfberry
foliage significantly (p<.001) more often than creosotebush (Larrea
tridentata) foliage [30].
PALATABILITY :
NO-ENTRY
NUTRITIONAL VALUE :
Mineral composition values of pale wolfberry collected in May in the
northern Mohave Desert are available [45].
COVER VALUE :
Dense thickets [43] of pale wolfberry probably provide cover for birds
and small mammals.
VALUE FOR REHABILITATION OF DISTURBED SITES :
Specific information regarding the use of pale wolfberry for
rehabilitating disturbed sites is not available in the literature.
Wolfberries (Lycium spp.), however, have been used to rehabilitate
abandoned farmland in the Sonoran Desert lowlands and disturbed sites
near Red Rock, Arizona. The sites were restored by establishing berms
on the contour and then seeding with wolfberry and other desert shrubs
[22].
OTHER USES AND VALUES :
Historically, Native Americans have eaten pale wolfberry berries and
have used the plant for a wide variety of medicinal purposes [23,33,43].
Pale wolfberry is grown as an ornamental [33,43].
MANAGEMENT CONSIDERATIONS :
NO-ENTRY
BOTANICAL AND ECOLOGICAL CHARACTERISTICS
SPECIES: Lycium pallidum | Pale Wolfberry
GENERAL BOTANICAL CHARACTERISTICS :
Pale wolfberry is a spiny, densely branched shrub with stems 3.3 to 9.9
feet (1-3 m) tall. Branches may be spreading to erect. The axillary
flowers are bell-shaped and are borne singly or in clusters. The fruit
is a red juicy berry with 20 to 50 seeds [20,31,33,43,47]. Pale
wolfberry may form dense thickets [43].
The distribution of small and large roots of pale wolfberry on desert
pavement underlain by caliche at 20 to 40 inches (50-100 cm) [2] at Rock
Valley, Nevada follows (values are percent of total root system weight)
[44]:
Depth
0-10 cm 10-20 cm 20-30 cm 30-40 cm 40-50 cm 50+ cm
______________________________________________________________________
large 27.5 28.3 9.8 5.4 3.5 0
small 2.9 10.5 6.5 3.2 2.6 0
The exact sizes of large and small roots were not given.
The roots of wolfberry species are tough and fibrous. Root systems are
relatively extensive in comparison with aerial portions, often extending
25 to 30 feet (7.5-9.0 m) from the plant [42].
Phytomass measurements for new leaf, stem, flower, and fruit
productivity of pale wolfberry at Rock Valley, Nevada in wet and dry
years are available in the literature [5]. Estimated aboveground net
productivity values of pale wolfberry at the same site for the period
1971 to 1976 are also available [39].
RAUNKIAER LIFE FORM :
Phanerophyte
REGENERATION PROCESSES :
Pale wolfberry regenerates from cuttings, root suckering, and layering. It
also sprouts from the base when damaged [42,43].
Pale wolfberry seeds are probably dispersed by birds and other animals,
like those of other wolfberry species [28].
Three pale wolfberry seedlings established at a Rock Valley, Nevada, site
in 1972, but none survived to the following year [2].
Good seed crops are produced by wolfberry species almost every year.
After extraction, seeds should be dried and stored in sealed containers
at 41 degrees Fahrenheit (5 deg C), or stratified in moist sand.
Stratified seeds of other wolfberry species maintain good viability for
6 months. Dormancy in wolfberry seeds is variable. Some wolfberry
species seeds germinate well without pretreatment, while germination of
others is improved by stratification. Seeds can be sown in the fall as
soon as the fruits ripen, or stratified seed can be sown in the spring
and covered lightly with about 0.25-inch (0.64-cm) of soil.
Two-year-old seedlings may be outplanted [36].
SITE CHARACTERISTICS :
Pale wolfberry is found on plains and flats, along washes and arroyos,
on dry rocky hills, mesas, and bajadas, and on rocky slopes and canyons
of hills and mountains [18,19,29,23,31,33,46]. It is tolerant of saline
soils [45].
In the Mohave Desert at Rock Valley, Nevada, pale wolfberry occurs in
desert scrub vegetation on sites at 3,300 feet (1,000 m) elevation with
soils derived from calcareous alluvium. The soil surface is
well-developed desert pavement underlain by a caliche layer that
prevents root penetration [2,3,40].
Pale wolfberry mostly occurs at the following elevations:
feet meters
_____________________________________________________________________
Arizona 3,500-7,000 1,060-2,120 [23]
California below 2,500 below 757 [31]
below 3,960 below 1,200 [20]
Colorado 5,000-7,000 1,500-2,120 [18]
Texas 3,000-7,000 900-2,120 [43]
Trans-Pecos, TX 400-5,200 120-1,575 [33]
Utah 3,300-6,170 1,000-1,870 [47]
SUCCESSIONAL STATUS :
Little information is available on the successional status of pale
wolfberry. It occurs in mid-seral and late seral communities of the
upper Rio Puerco watershed in New Mexico that are dominated by oneseed
juniper (Juniperus monosperma), broom snakeweed (Gutierrezia sarothrae),
or alkali sacaton (Sporobolus airoides) [14].
SEASONAL DEVELOPMENT :
Pale wolfberry flowers from February to May or June throughout its
range [23,31,33,43]. In the Mohave Desert pale wolfberry is one of the
first plants to break dormancy, and does so when night temperatures are
around freezing and maximum air temperatures average 60 degrees
Fahrenheit (15 deg C) [1,3,38]. It is also one of the first species to
shed its leaves when air and soil temperatures increase above 86 degrees
Fahrenheit (30 deg C). Pale wolfberry may produce leaf and flower buds
after summer and fall rains [1,3]. The following dates were recorded
for phenological development of pale wolfberry at Rock Valley, Nevada,
over an 8-year period [38]:
Year first leaf first flower first fruit

FIRE ECOLOGY
SPECIES: Lycium pallidum | Pale Wolfberry
FIRE ECOLOGY OR ADAPTATIONS :
Many perennial desert shrubs are not well adapted to fire [12], but some
exhibit fire adaptive traits [27]. These traits are generally only
weakly developed [35].
Since pale wolfberry sprouts from the root crown following damage [43],
it probably sprouts after fire [27]. However, it may take many years
for desert shrubs to regain their former densities on burned sites [35].
The sprouting ability of pale wolfberry is most likely dependent on fire
severity. Dense clumps of brush containing pale wolfberry may be
somewhat impervious to fire, as are clumps containing Berlandier
wolfberry (L. berlandieri) [10].
Wolfberry species seedling establishment was noted after a fire at a
Sonoran Desert site. The seeds may have survived fire in the soil or on
burned plants, or may have been dispersed from adjacent unburned areas
[35].
POSTFIRE REGENERATION STRATEGY :
Tall shrub, adventitious-bud root crown
Secondary colonizer - off-site seed
FIRE EFFECTS
SPECIES: Lycium pallidum | Pale Wolfberry
IMMEDIATE FIRE EFFECT ON PLANT :
Severe fires may kill pale wolfberry, but low- to moderate-severity fires
probably only consume its aerial portions.
DISCUSSION AND QUALIFICATION OF FIRE EFFECT :
NO-ENTRY
PLANT RESPONSE TO FIRE :
Specific information on the response of pale wolfberry to fire is not
available in the literature. In general, wolfberry species sprouted
rapidly after controlled June fires in Sonoran Desert scrub vegetation
near Phoenix, Arizona. The well developed wolfberry root systems
escaped damage from the fire, allowing them to capitalize on increased
water and nitrogen availability in the postfire environment.
Wolfberries had established their former density and cover by 35
postfire months. Wolfberry plants had similiar responses in both open
shrub and tree microhabitats [27].
Wolfberry species sprouted and seedlings established within 3 years
following a June wildfire in a Sonoran desert scrub community near
Phoenix, Arizona. No information was given on fire severity or
intensity [35].
Berlandier wolfberry, a related species, was reduced by prescribed
fires in southern Texas [10,11,17], but the effects were short-lived and
canopy diameter had recovered to prefire levels by the end of the first
growing season following the fire [17].
DISCUSSION AND QUALIFICATION OF PLANT RESPONSE :
NO-ENTRY
FIRE MANAGEMENT CONSIDERATIONS :
Fires are not prevalent in many desert communities due wide spacing
between shrubs and sparse ground cover [12,21]. Unusually heavy winter
rains, however, may produce a cover of annual species dense enough to
carry a fire when cured [21]. Many perennial desert shrubs are poorly
adapted to fire [12]. Wolfberries in particular may be susceptible to
repeated burning [27]. Postfire colonization by desert shrubs is very
slow initially and may take hundreds of years [12,35]. Rogers and
Steele [35] suggested a conservative approach when using fire to manage
desert regions.
