In the Intermountain region and the northern Rocky Mountains, small 
camas is usually found in mountain grassland and prairie communities.
West of the Cascade-Sierra Nevada crest, it occurs in both forest and
grassland types [10,13,22].


SPECIES: Camassia quamash
IMPORTANCE TO LIVESTOCK AND WILDLIFE: Livestock, elk, moose, and caribou graze small camas [23]. Pigs consume the bulbs [6]. PALATABILITY: Small camas provides fair to good graze for sheep and cattle [23]. NUTRITIONAL VALUE: Small camas forage is poor in energy and protein value [26]. The nutrient composition of fresh bulbs (per gram dry weight) is as follows [14]: calories 3.90 calcium (mg) 1.76 protein (g) 0.13 iron (mg) 0.23 carbohydrate (g) 0.80 magnesium (mg) 0.40 lipid (g) 0.03 zinc (mg) 0.03 COVER VALUE: NO-ENTRY VALUE FOR REHABILITATION OF DISTURBED SITES: Small camas was planted for mountain grassland restoration in western Washington, using bulbs salvaged from a nearby area undergoing subdivision [1]. Plants can also be established by fall planting of seed [20]. OTHER USES AND VALUES: Small camas bulbs were eaten by western Indians, trappers, and early settlers [3,6,22,23]. Many western Indian tribes also used the bulbs as a trade item [22]. Small camas is planted as an ornamental [3]. OTHER MANAGEMENT CONSIDERATIONS: Small camas decreases under sheep grazing [22].


SPECIES: Camassia quamash
GENERAL BOTANICAL CHARACTERISTICS: Small camas is a native perennial forb. Its peduncle is from 8 to 20 inches (20-50 cm) in height and supports a terminal raceme. The peduncle and basal leaves attach to a bulb that is up to 1.5 inches (6 cm) across. Its roots are fibrous. The fruit is a three-celled capsule with 5 to 10 seeds per cell [12,13,23]. RAUNKIAER LIFE FORM: Geophyte REGENERATION PROCESSES: Small camas reproduces from seed and bulb offsets [18,22]. Clones flower at age 2 or 3 years [18]. SITE CHARACTERISTICS: Small camas grows on sites that are moist to wet in spring but dry by late spring or summer [4,6,8,12,25]. It is commonly found near vernal pools, springs, and intermittent streams [10]. It occurs at elevations ranging from sea level to 7,000 feet (2,134 m) in California [13] and from 6,240 to 7,950 feet (1,890-2,410 m) in Utah [25]. Associated species in the Intermountain region are snowberry (Symphoricarpos albus), bluebunch wheatgrass (Pseudoroegneria spicata), Idaho fescue (Festuca idahoensis), Douglas grass-widow (Sisyrinchium douglasii), Hooker balsamroot (Balsamorhiza hookeri), rush pussytoes (Antennaria luzuloides), Wyeth buckwheat (Eriogonum heracleoides), and western yarrow (Achillea millefolium) [17]. SUCCESSIONAL STATUS: Small camas is shade intolerant [10]. In forested areas, it is found on open sites created by disturbance. In grasslands and meadows, it is most prevalent in initial and early seral communities but also occurs in later seres [1,10,22]. SEASONAL DEVELOPMENT: Small camas flowers from May to July, depending upon elevation and snow cover [4,9,12]. Leaves die and seeds are dispersed from late May to August [22].


SPECIES: Camassia quamash
FIRE ECOLOGY OR ADAPTATIONS: Soil insulates the meristematic tissue in small camas bulbs from damage by fire [22]. 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". POSTFIRE REGENERATION STRATEGY: Geophyte, growing points deep in soil


SPECIES: Camassia quamash
IMMEDIATE FIRE EFFECT ON PLANT: Fire presumably top-kills small camas. DISCUSSION AND QUALIFICATION OF FIRE EFFECT: NO-ENTRY PLANT RESPONSE TO FIRE: Small camas on the Palouse prairie of eastern Washington increases with frequent fire [1]. Data regarding small camas postfire recovery are lacking. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE: NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS: Because growth and flowering occur in spring and early summer, short-interval fires in spring or early summer would probably reduce small camas populations. Northwest Coast Indians reportedly set fires annually. This optimized small camas production by maintaining an open prairie [20,21].
