ABBREVIATION : CORAUR SYNONYMS : Capnoides aureum (Willd.) Kuntze [13] SCS PLANT CODE : COAU2 COMMON NAMES : golden corydalis golden smoke TAXONOMY : The currently accepted scientific name of golden corydalis is Corydalis aurea Willd. [9,11,20]. The following subspecies are recognized [12,16,27]: C. aurea ssp. aurea --racemes generally surpassed by leaves C. aurea ssp. occidentalis (Engelm.) Ownbey --racemes generally surpassing leaves Some authors, however, make this distiction at the varietal level [9,11]. LIFE FORM : Forb FEDERAL LEGAL STATUS : No special status OTHER STATUS : Golden corydalis is classified as threatened in New York. Its state rank there is listed as S1 (critically imperiled in New York State because of extreme rarity or is extremely vulnerable to extirpation from the New York State due to biological factors [29].


SPECIES: Corydalis aurea
GENERAL DISTRIBUTION : Golden corydalis is distributed from Quebec west to Alaska and south (from east of the Cascade Mountains) to California [14,16,20,28]. In the central United States it is found to Texas and Missouri. Golden corydalis also occurs through the New England states to West Virginia [9,11,12]. Corydalis aurea ssp. occidentalis has more western and southern distribution than C. aurea spp. aurea [14,11,12].

SPECIES: Corydalis aurea
IMPORTANCE TO LIVESTOCK AND WILDLIFE : Golden corydalis produces several alkaloids and may be poisonous to sheep and cattle [5,16,17]. PALATABILITY : Golden corydalis is unpalatable to horses, sheep, and cattle [6]. NUTRITIONAL VALUE : Golden corydalis is poor in energy and protein value [6]. COVER VALUE : NO-ENTRY VALUE FOR REHABILITATION OF DISTURBED SITES : NO-ENTRY OTHER USES AND VALUES : NO-ENTRY OTHER MANAGEMENT CONSIDERATIONS : NO-ENTRY


SPECIES: Corydalis aurea
GENERAL BOTANICAL CHARACTERISTICS : Golden corydalis is a winter annual or biennial forb. It is highly branched with stems usually 4 to 20 inches (10-50 cm) tall, but becoming prostrate with age [11,12,20]. Leaves are one to four times pinnately compound [12,20,28]. Flowers are borne in racemes. The fruits are capsules with seeds about 0.08 inches (0.2 cm) in diameter [11,20]. Golden corydalis has a slender taproot [5,28]. RAUNKIAER LIFE FORM : Hemicryptophyte Therophyte REGENERATION PROCESSES : Golden corydalis reproduces by long-lived, wind-dispersed seed [2,4,6,15]. Seeds may lie dormant for over 160 years [15]. SITE CHARACTERISTICS : Golden corydalis grows on open prairies and hillsides, along streams and rocky banks or shores, and in open woodlands [9,11,12,13,26]. It is also often found on disturbed sites such as along roads, in clearings, and around gravel or sand pits [7,22,26,27]. It grows well on moderate to steep slopes [6]. Golden corydalis grows in moist to dry, well-drained rocky, gravelly, or sandy soil [6,14]. Lower and upper elevational limits of golden corydalis in a few western states are as follows: Feet Meters Arizona 1,500-9,500 454-2,878 [16] California 5,000-7,500 1,515-2,272 [20] Colorado 5,000-10,500 1,515-3,181 [13] Utah 2,640-11,071 800-3,355 [28] SUCCESSIONAL STATUS : Obligate Initial Community Species Golden corydalis usually appears in communities following disturbance and dies out within a few years if conditions are stable [26]. SEASONAL DEVELOPMENT : Depending on latitude, golden corydalis generally flowers from May to June or July [9,11,12,14,20]. In Arizona, however, it blooms from February to June [16].


SPECIES: Corydalis aurea
FIRE ECOLOGY OR ADAPTATIONS : Golden corydalis reproduces from long-lived seeds. It may also invade recently burned areas by wind-dispersed seed [2]. Germination of seeds of other corydalis species (C. sempervirens) is stimulated by fire [25]. Anderson [1] stated that golden corydalis regenerates vegetatively following fire, but no specific information was given. 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 : Ground residual colonizer (on-site, initial community) Initial-offsite colonizer (off-site, initial community)


SPECIES: Corydalis aurea
IMMEDIATE FIRE EFFECT ON PLANT : Golden corydalis is probably always killed by fire. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : Golden corydalis quickly invades recently burned areas by seed. However, its survival in the postfire community appears to be very short lived. Golden corydalis invaded recently burned areas by wind-dispersed seed after stand-replacing summer fire in lodgepole pine (Pinus contorta) stands in Colorado. It was not present in adjacent unburned stands, but in burned areas it had a frequency of 27.9 percent in the first postfire year. By the second postfire year, frequency had diminished to 9.7 percent, and it was thereafter eliminated from the postfire community [2]. Golden corydalis was also present 1 year after moderate-severity fires in lodgepole stands in Yellowstone National Park. Information for response after postfire year 1, however, was not given [1]. Golden corydalis bloomed and set seed in the first growing season following severe fire in Douglas-fir (Pseudotsuga menziesii)/ninebark (Physocarpus malvaceus) habitats in western Montana. However, it had almost completely disappeared from the postfire community by the second growing season. The origin of the postfire seedlings was unknown, but it may have been soil-stored seed [4]. Golden corydalis flowered the August following a May fire in black spruce (Picea mariana)-white spruce (P. glauca) stands in Alaska [15]. No additional information was given. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : NO-ENTRY
