Fire Ecology
provided by Fire Effects Information System Plants
More info for the terms:
litter,
root crown,
seedSpecific information is not available regarding the fire ecology and
adaptations of Mohave rabbitbrush. However, most rabbitbrush species
vigorously sprout from the root crown after fire and therefore establish
well on burned sites. They also have prolific seed production and
vigorous spring growth [
20].
Rabbitbrush species are prolific litter producers and investigations
have shown that this has contributed to excessive fire fuels on some
sites [
20].

Importance to Livestock and Wildlife
provided by Fire Effects Information System Plants
Mohave rabbitbrush communities provide a home for many bird species. In
Mohave rabbitbrush washes in the Mojave Desert, winter bird densities
were 50 to 60 times higher and the number of species was eight times higher
than in the surrounding open desert. At the same site, breeding bird
densities were 15 times higher with 6 times the number of species [

Other uses and values

Mohave rabbitbrush reportedly has a rubber content of 2.5 percent or
more [
11].
Rabbitbrush species are burned by the Hopi in religious ceremonies. The
Hopi also use them in windbreaks, for making arrows, and in wicker work.
A yellow dye is obtained from the flowers, and a green dye from the
inner bark [
11].

Phenology
provided by Fire Effects Information System Plants

may also flower in May and June [
11,
16,

rabbitbrush species ripen over 2 to 4 weeks, and many are dislodged from
the bush during that time. Seeds normally ripen in the late fall and
early winter [

Plant Response to Fire
provided by Fire Effects Information System Plants
More info for the term:
root crownInformation is not available regarding Mohave rabbitbrush response to
fire. However, if consistent with other rabbitbrush species, desert
rabbitbrush probably recovers well after fire by sprouting from the root
crown. Mohave rabbitbrush sprouts and seedlings are probably abundant
the first years after fire.

Regeneration Processes
provided by Fire Effects Information System Plants
More info for the terms:
root crown,
seedMohave rabbitbrush reproduces by seed. Ripe achenes are easily
dislodged from the plant by wind or any abrasive action [
15]. The
majority of rabbitbrush (Chrysothamnus spp.) seeds are wind
disseminated. Dissemination distances ranging from 130 to 165 yards
(117-148 m) have been recorded for other species of rabbitbrush [
26].
No specific information was available on germination or viability of
Mohave rabbitbrush seeds; however, information is available on other
rabbitbrush species [
15,
24,
26]. Stevens and others [
27] found that 80
percent of rubber rabbitbrush (Chrysothamnus nauseosus) seeds stored for
2 years germinated, but seeds stored for 3 and 4 years had reduced
germination of 65 and 34 percent, respectively. Seedlings of most
rabbitbrush species are easily established by shallow planting on rough
soil surfaces [
15].
If consistent with other rabbitbrush species, Mohave rabbitbrush can
also reproduce by sprouting from the root crown [
20].

Value for rehabilitation of disturbed sites
provided by Fire Effects Information System Plants
More info for the terms:
litter,
seedRabbitbrush species (Chrysothamnus spp.) are useful for erosion control
because of their deep roots, heavy litter production, and ability to
establish on harsh sites. They establish well naturally from seed and
artificially by transplanting [
20]. Mohave rabbitbrush has been used for
revegetation of sulfur mine spoils in Nevada. One year following
planting container-grown Mohave rabbitbrush on the Leviathan Mine in
Nevada, Mohave rabbitbrush showed 88 percent survival; 4 years later,
survival had decreased to 9 percent. Mohave rabbitbrush can be
transplanted on spoils without site preparation [
5].

Ericameria paniculata
provided by wikipedia EN
Ericameria paniculata (formerly Chrysothamnus paniculatus)[4] is a species of flowering plant in the sunflower family Asteraceae, native to the southwestern United States. It is an evergreen yellow-flowered desert shrub.
It is known by several common names, including black-banded rabbitbrush, Mojave rabbitbrush,[5] and punctate rabbitbrush.[6][7] The stems often have black, gummy bands.[7]
Description
Ericameria paniculata is a branching shrub reaching up to 2 meters (80 inches) tall. The spreading or erect stems are glandular and resinous and are often banded or splotched with black from a smut fungus Puccinia splendens.[8] The glandular leaves are filiform (thread-shaped or narrowly oblanceolate) up to 3.5 centimeters (1.4 inches) in length.[6]
The inflorescence is an array of small, yellow flower heads, each of which contains 5 to 8 disc florets but no ray florets. The fruit is up to a centimeter (0.4 inches) long including its long pappus. They are wind-dispersed.[9][6][10]
It flowers from June to December.[7]
Range and habitat
Ericameria paniculata is native to the deserts of Arizona, Nevada, southern California, southwestern Utah. It is particularly common in the Mojave Desert.[9][11][12]
It is found in a great variety of habitats, including disturbed areas such as roadsides. It tolerates poor soils. Its companions may include Larrea tridentata (creosote), Yucca brevifolia (Joshua tree), Baccharis, Hymenoclea salsola (white burrobush), Atriplex polycarpa (desert saltbush), and Acacia greggii (catclaw acacia).[9][6]
