SPECIES: Fendlera rupicola
GENERAL DISTRIBUTION : Fendlerbush is found from the Sabinal River to the Pecos River in scattered locations in Texas. It is common in the higher mountains of the Trans-Pecos region. It also occurs in the Davis, Chisos, and Guadalupe mountains; northward and westward into New Mexico, Colorado, Utah, and Arizona; and southward into Mexico [12,22]. Sickle-leaf fendlerbush is distributed through New Mexico, Arizona, Colorado, and sparsely in Texas in the Trans-Pecos mountains. Wright fendlerbush is distributed through west Texas, New Mexico, Arizona, and Chihuahua, Mexico [22].

Fendlerbush is often found associated with oneseed juniper (Juniperus monosperma), alligator juniper (J. deppeana), true pinyon (Pinus edulis), wavyleaf oak (Quercus undulata), skunkbush sumac (Rhus trilobata), mountain-mahogany (Cercocarpus breviflorus), and antelope bitterbrush (Purshia tridentata) [7,15].


SPECIES: Fendlera rupicola
IMPORTANCE TO LIVESTOCK AND WILDLIFE : Fendlerbush is browsed by goats, deer, bighorn sheep, and cattle [12]. In the San Cayetano Mountains, Arizona, fendlerbush made up 11 percent of the white-tailed deer diet during the hot, dry season (April- June); this season appears to be the most critical period of the year for deer herds in the desert southwest [1,2]. PALATABILITY : Fendlerbush palatability is high for goats in New Mexico. It is closely grazed by cattle in central Arizona [21], and is a frequent diet item of white-tailed deer in the San Cayetano Mountains, Arizona [1,2]. NUTRITIONAL VALUE : NO-ENTRY COVER VALUE : NO-ENTRY VALUE FOR REHABILITATION OF DISTURBED SITES : NO-ENTRY OTHER USES AND VALUES : Fendlerbush is grown as an ornamental. It is suitable for rock gardens in well-drained, sunny situations, and has been grown as far north as New England [4,12,18]. OTHER MANAGEMENT CONSIDERATIONS : Fendlerbush decreases in response to grazing [25]. Fendlerbush has vesicular-arbuscular endomycorrhizal associations [6,26]. These fungi increase fendlerbush growth by increasing phosphorus absorption [26].


SPECIES: Fendlera rupicola
GENERAL BOTANICAL CHARACTERISTICS : Fendlerbush is a native, deciduous, widely-branched shrub [12,22,24]. It grows 3 to 9 feet (1-3 m) high [4,12,22,24]. The leaves are thick, twisted, 0.2 to 1.6 inches (5-40 mm) long and 0.08 to 0.28 inches (2-7 mm) wide [13,24]. The flowers are solitary or two to three together at the ends of short branches [24]. The fruit is a four-celled capsule which remains on the plant all year [11,13]. Fendlerbush bark is shreddy [11]. It generally has deep roots [4]. Fendlerbush can endure intense heat and considerable drought [21]. RAUNKIAER LIFE FORM : Phanerophyte REGENERATION PROCESSES : Fendlerbush reproduces by seed [4,22]. Commercial production is accomplished through seed that is stratified at 41 degrees Fahrenheit (5 deg C) for 60 to 90 days [4]. Fendlerbush can also reproduce via branch cuttings [4,22]. SITE CHARACTERISTICS : Fendlerbush is commonly found on rocky ledges and steep slopes of cliffs and canyons at elevations of 3,000 to 7,000 feet (914-2,133 m) [16,22,23]. Fendlerbush thrives on very dry, well-drained, poor soils that may be rocky and/or alkaline [4,21,22]. Less than 15 inches (38.1 cm) of annual precipitation have been measured in its natural habitat [4]. SUCCESSIONAL STATUS : Fendlerbush occurs in nearly all stages of succession. It is most common in mid- to late-seral communities. In Mesa Verde National Park, fendlerbush maximum cover and frequency was not reached until 80 years after a fire in a pinyon-juniper community. In an adjacent 400-year-old climax pinyon-juniper stand, fendlerbush cover was only 2 percent; frequency was 8 percent [7]. SEASONAL DEVELOPMENT : Fendlerbush generally flowers from March through June, depending on the location [12,22]. In the Trans-Pecos, Texas, fendlerbush sometimes flowers through August [16]. Fendlerbush fruits mature in July and August [22].

FIRE ECOLOGY OR ADAPTATIONS : Little information is available regarding fendlerbush fire ecology and adaptations. Erdman [7] suggested that fendlerbush probably recovers after fire by sprouting from the root crown. Pinyon-juniper communities where fendlerbush is commonly found historically burned every 10 to 30 years, which favored dominance by grasses. However, for the last 70 years, heavy livestock grazing has reduced grass competition and fuel, and shrub cover has increased. This has decreased fire occurrence and lowered the intensity of fires that do occur [27,28]. On 23 grazed transects in desert shrub communities where fendlerbush occurs in the Guadalupe Mountains, New Mexico, shrubs had only 6.4 to 6.6 percent cover. Bare ground cover was 33.8 to 42.4 percent, and litter cover was 6.1 to 12 percent [25]. POSTFIRE REGENERATION STRATEGY : Small shrub, adventitious-bud root crown Secondary colonizer - off-site seed FIRE REGIMES : Find fire regime information for the plant communities in which this species may occur by entering the species name in the FEIS home page under "Find Fire Regimes".

IMMEDIATE FIRE EFFECT ON PLANT : Information was not available regarding the immediate effects of fire on fendlerbush. Fendlerbush is probably top-killed or killed by most fires. PLANT RESPONSE TO FIRE : In Mesa Verde National Park, 4 years after a July/August, 1959 natural fire in a pinyon-juniper community, fendlerbush had no significant cover. Fendlerbush frequency was 2 percent. Twenty-nine years following a July fire in a nearby pinyon-juniper community, fendlerbush made up 1 percent of the cover and had 6 percent frequency. Fendlerbush maximum cover and frequency was not reached until almost 80 years after a pinyon-juniper fire in Mesa Verde National Park. At this time fendlerbush made up 14 percent of the cover and had 48 percent frequency [7]. FIRE MANAGEMENT CONSIDERATIONS : NO-ENTRY
