Wildlife

Established plants of fernleaf biscuitroot, like other members of the Lomatium genus, begins growth very early in the spring, often just following snow melt, providing crucial early forage for many wildlife and domestic animals, It is considered a very valuable forage species due to its large stature and high biomass production levels, Ogle and Brazee (2009) rate members of the genus as desirable spring and summer forage for cattle, sheep, horses, elk, deer and antelope, Early green-up and flowering make this an important species for early spring pollinators and other insects, It is highly attractive to some bees, Pollinator surveys at native stands of fernleaf biscuitroot showed frequent visitation by several species of Andrena and Micrandrena that are oligolectic (pollen specialists) for this genus, In cultivated stands, honeybees and overwintering queens of Halictus and Lasioglossum bee species are sometimes frequent, Micrandrena spp, on fernleaf biscuitroot, Jim Cane, ARS Bee Biology and Systematics Lab, Logan, UT Fernleaf biscuitroot has been identified as an important plant species in sage-grouse habitat, Pre-laying sage-grouse hens eat the foliage (Barnett and Crawford, 1994), Use soil moisture sensors to measure the soil moisture of Fernleaf Biscuitroot., Sage-grouse chicks consume the plants, as well as associated insects (Drut et al,, 1994),

Ethnobotanic

Fernleaf biscuitroot, known as Toza by the Numic speaking tribes of the Great Basin, was commonly used for food, medicine, and ceremonial purposes (Meilleur et al., 1990). It is one of the most widely used plant species in native North American culture (Moerman, 1998).

Food

Many western Native American tribes used fernleaf biscuitroot as a food source. Gosiute Indians, Great Basin Indians, and Montana Indians used tender young shoots as cooked greens (Blankenship, 1905; Chamberlin, 1911; Nickerson, 1966). Members of the Nez Perce, Okanagon, and Thompson tribes cooked and ate the thick fleshy taproots (Perry, 1952; Hart, 1992). The seeds were used as food by the Gosiute tribe (Chamberlin, 1911), and Great Basin Indians made a beverage from boiled roots (Nickerson, 1966).

Medicinal

Fernleaf biscuitroot was commonly used by Native Americans for a wide variety of ailments. Below is a partial list of medicinal applications of fernleaf biscuitroot by various Native American Tribes compiled from Chamberlin (1911), Park and Fowler (1989), Grinnell and Fitzgerald (2008), Hart (1992), McClintock (1909), Nickerson (1966), Steedman (1928).

It is available in the commercial health market as whole root or as a tincture.

Veterinary

Paiute, Shoshoni and Ute Indians caused their horses to inhale smoke of burning roots to treat distemper (Train et al., 1941; Chamberlin, 1911). Nevada Indians administered a poultice of ground fernleaf biscuitroot chips for head troubles and sores (Murphey, 1990)

Fishing

Okanagan-Colville and Northern Paiute Indians pounded roots and soaked them in water to poison and catch fish (Turner et al., 1980; Park and Fowler, 1989).

Ceremony

Blackfeet Indians burned smashed root as incense (McClintock, 1909). Navajo Indians administered an infusion of dried and ground fernleaf biscuitroot mixed with other plants to patients as part of their Mountain Top Chant ceremony (Elmore, 1944).

Description

General: Carrot family (Apiaceae). Fernleaf biscuitroot is the largest member of the Lomatium genus. It is a perennial, herbaceous forb arising from a thickened woody taproot or caudex. Mature plants can be up to 1.3 m (51 in) tall. The leaves are ternate and pinnately compound. Blades of the larger mature leaves are 15 to 30 cm (6 to 12 in) long and the larger ultimate segments are 2 to 3 mm (0.08 to 0.12 in) wide. Flowering occurs from April through May. The flowers are yellow to purple, and born in umbels with 10 to 30 rays; each ray is 4 to 10 cm (1.6 to 3.9 in) long. Each umbel is composed of a combination of 50 to 200 male and hermaphroditic flowers (Thompson, 1998). Occasionally, all-male umbels are found, but the species is clearly hermaphroditic with both stamens and pistils in the same flower. The seeds are elliptical; 8 to 15 mm (0.6 in) long and 5 to 10 mm (0.4 in) wide with a thickened wing about 1 mm (0.04 in) wide. There are approximately 99,000 seeds per kg (45,000 seeds per lb) (USDA-NRCS, 2010). Fernleaf biscuitroot seed. Nancy Shaw, USDA-FS RMRS, Boise, ID The root is a large, sometimes branching, taproot reaching approximately 30 cm (1 ft) long and 5 cm (2 in) thick. Fernleaf biscuitroot taproots. Jim Cane, USDA-ARS Bee Biology Lab, Logan, Utah *NOTE: Fernleaf biscuit root foliage bears a strong resemblance to poison hemlock (Conium maculatum). The two can be distinguished vegetatively by the small purple spots found on hemlock stems and petioles. Hemlock also has white flowers instead of yellow or purple. Distribution: Fernleaf biscuitroot naturally occurs from British Columbia and Saskatchewan south to California and New Mexico and extends eastward to Wyoming and Colorado. For current distribution in North America, consult the Plant Profile page for this species on the PLANTS website. Habitat: This species is common in mountain and Wyoming big sagebrush, pinyon-juniper, and mountain shrub communities from 150 to 3,000 m (500 to 10,000 ft) throughout its range (Welsh et al., 2003; Hickman, 1993).

Adaptation

Fernleaf biscuitroot is adapted to coarse- to fine-textured soils with pH of 6.5 to 7.5. It can be found in a variety of plant communities in areas receiving 360 to 760 mm (14 to 30 in) or more mean annual precipitation (USDA-NRCS, 2010).

Establishment

Seed can be broadcast or drilled to 0.3 to 0.6 cm (1/8 to 1/4 in) into a well prepared, weed-free seedbed. This species should be seeded in late fall as a dormant planting to allow for natural stratification of the seed over winter.

Management

Once established, fernleaf biscuitroot is very competitive against weeds due to its long taproot; however additional measures to control weeds are necessary for seed production.

Pests and Potential Problems

Thompson (1998) conducted plant pest surveys at a natural stand of fernleaf biscuitroot near Pullman, Washington over a 10 year period. He found that the greatest threat to fernleaf biscuitroot was pocket gophers, which accounted for 43% of the plant mortality observed in his study. Plants were grazed by rabbits and deer. They were also attacked by leaf miners, gall causing flies and Puccinia rust. Additionally, fernleaf biscuitroot can be a host to ant-tended aphids, and the seeds are consumed by Smicronyx seed weevils (Cane, unpubl.). Colonization by the basidiomycete fungus Rhizoctonia solani has been observed following wet spring conditions (Tisserat, unpubl.).

Seed and Plant Production

Plant Production

Plant Production

Small scale production Seed matures in July into August. Wildland seed disarticulates readily and is easily hand collected. Very clean collections can be made by shaking ripened inflorescences over a bag or tarp. Minor screening to remove sticks provides excellent purity. Extended seed stratification is required for successful propagation of fernleaf biscuitroot. At the time of dispersal, the seeds have underdeveloped embryos which require a trigger for growth prior to germination. Scholten et al. (2009) observed that greatest embryo elongation occurred at temperatures of 3.4 to 5.5° C (38 to 42° F). The best germination percentages occurred at 3.4 C (38° F) with approximately 16 weeks of cold/moist stratification. Baskin and Baskin (2002) recommend a cold moist stratification for 330 days followed by 18° C germination conditions. In Pullman, Washington, best results were obtained when seed was sown into containers in the fall that were left outside to overwinter. Germination begins in March and growth continues for 3 to 4 months until the plants go dormant in late July or August. Containerized plants should be left outside in a lath house for an additional winter before transplanting the following spring. Flowering and seed production typically begins 3 years after transplanting (Skinner, 2004). Large scale production Seed can be drilled in rows at 82 to 98 PLS/m (25- 30 PLS/ft) or into weed barrier fabric at 45 to 60 cm (18 to 24 in) spacing. Dormant fall seedings are recommended to permit over-winter stratification. Three year old plants grown in weed barrier fabric. Loren St. John, USDA-NRCS, Aberdeen, ID PMC Above ground growth is slow as young plants invest significant resources to produce a substantial taproot. Plants grow in early spring into summer and go dormant in mid-summer, giving the appearance of mortality. During the first year of establishment, most plants will only produce a few leaves. Seed production fields at Aberdeen, Idaho did not produce flowers or seed until the fourth year of production. Similarly, organic herb growers report 4 year old plants which are still not ready for harvest, but it was not indicated if these plants were from seed or transplants (Lomatium.com, 2010). Experimental plots at Ontario, Oregon, using supplemental irrigation produced seed in the fourth season with peak yields of 482 kg/ha (430 lb/ac) (Shock et al. 2010). Fernleaf biscuitroot production field. Nancy Shaw, USDA-FS RMRS, Boise, Idaho Good weed control can be achieved through the use of weed barrier fabric and hand roguing. Because fernleaf biscuitroot enters dormancy in early summer, foliar herbicide applications of glyphosate to surrounding weeds are possible after senescence. Always read and follow label and safety instructions for each control method. USDA-NRCS does not guarantee or warranty any products or control methods named, and other products may be equally effective. New techniques are being investigated regarding the feasibility of growing fernleaf biscuitroot densely in rooting beds prior to field establishment. This method would allow a grower to sacrifice a much smaller area in the first 1 to 2 years of plant development while the plants are not producing seed. Trials indicate that taproots transplanted in autumn establish well (Jensen, 2010). Shock et al. (2010) at Ontario, Oregon showed a significant positive response to irrigation with 10 and 20 cm (4 and 8 in) additional water. Ontario has a mean annual precipitation of 24 cm (9.5 in) (U.S. Climate Data, 2010), bringing the total received water to approximately 46 cm (18 in) for optimum seed production. Though fernleaf biscuitroot flowers are self-fertile, they still require visitation by pollinators for fertilization to occur. Cane (2007) showed a 60X increase in seed set in the presence of pollinators. Fernleaf biscuitroot has a very restricted range of natural pollinators; primarily the oligolectic Andrena and Micrandrena spp., thus developing a manageable pollinator for seed production is unlikely. In cultivation, honey bees and sweat bees may suffice, but a planting trial is recommended. Seed can be harvested in production fields via a vacuum type harvester or flail vac (Bair and Tilley, 2010). Seed can be cleaned using an air screen cleaner. Purities approximating 100% are achievable with minimal effort. Cultivars, Improved and Selected Materials (and area of origin) Common wildland collected seed is available from commercial sources. There are currently no commercial releases of fernleaf biscuitroot. Commercial growers are producing pooled Source Identified seed representative of Omernik Ecoregion 12 (Snake River Plain) and 80 (Northern Basin and Range).
