BOTANICAL AND ECOLOGICAL CHARACTERISTICS

SPECIES: Dracocephalum parviflorum
GENERAL BOTANICAL CHARACTERISTICS : American dragonhead is a native annual, biennial, or short-lived perennial forb. Solitary or clustered stems arise from a taproot and are 6 to 32 inches (15-80 cm) tall [8]. Leaves are coarsely serrate and flowers are crowded in a dense terminal or axillary cluster. The fruits are nutlets [29]. RAUNKIAER LIFE FORM : Hemicryptophyte REGENERATION PROCESSES : American dragonhead is a seedbanking species. Seeds are large and are not wind-dispersed. Buried seeds remain viable for a long period of time [13]. Seeds require fire or other disturbance for germination [20]. SITE CHARACTERISTICS : American dragonhead commonly grows on open, moist sites [8,17,20] and in disturbed areas [9,15,18]. In the Great Plains it grows on gravelly soils along streams, in open woodlands, or on moist wooded hillsides [15]. In the Northeast, American dragonhead is found on rocky or gravelly calcareous soils in recently cleared areas [12]. It occurs from 4,500 to 10,000 feet (1,360-3,000 m) elevation in Colorado [16], and from 4,850 to 10,890 feet (1,470-3,300 m) elevation in Utah [29]. Some species commonly associated with American dragonhead include russet buffaloberry (Shepherdia canadensis), Oregon-grape (Mahonia repens), snowberry (Symphoricarpos spp.), serviceberry (Amelanchier spp.), western yarrow (Achillea millefolium), strawberry (Fragaria spp.), heartleaf arnica (Arnica cordifolia), fireweed (Epilobium angustifolium), Bicknell geranium (Geranium bicknellii), and wild hollyhock (Iliamna rivularis) [1,4]. SUCCESSIONAL STATUS : Obligate Initial Community Species American dragonhead is prominent in initial or early successional communities following disturbance [26]. Its seedbanking ability allows colonization of disturbed areas even when no parent plants are present [13]. American dragonhead has usually disappeared or declined in importance within the first few years following disturbance [4]. SEASONAL DEVELOPMENT : American dragonhead flowers from June to August in the Intermountain region [8], and from June to September in the Great Plains [15].

FIRE ECOLOGY

SPECIES: Dracocephalum parviflorum
FIRE ECOLOGY OR ADAPTATIONS : Seedbanked American dragonhead seeds are fire activated, germinating after even severe fire [22]. American dragonhead flowers during the first few postfire years. New seeds remain dormant in the soil until the next stand-replacing fire or other disturbance occurs [1]. POSTFIRE REGENERATION STRATEGY : Ground residual colonizer (on-site, initial community) Secondary colonizer - on-site seed

FIRE EFFECTS

SPECIES: Dracocephalum parviflorum
IMMEDIATE FIRE EFFECT ON PLANT : NO-ENTRY DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : American dragonhead is a residual colonizer that is prominent in initial postfire communities, even after holocaustic fires [26]. After fire in Douglas-fir (Pseudotsuga menziesii) habitats in central Idaho, American dragonhead dominated the initial postfire vegetation. Plants were absent from preburn communities and adjacent 20-year-old burns. Frequencies in postfire years 1 and 2 were 96 and 100 percent, respectively. American dragonhead comprised 30 percent of all plant cover in the first postfire year and 37 percent of all cover in the second postfire year. It's cover was greatly reduced by the third growing season following the fire [21]. In ponderosa pine (Pinus ponderosa) types in the Black Hills of South Dakota, American dragonhead exhibited initial postfire prominence but disappeared or greatly declined in importance by the second or third postfire growing season [23]. It showed the same response in jack pine (Pinus banksiana) habitats in Saskatchewan [6], white spruce (Picea glauca) habitats in Alaska [28], quaking aspen (Populus tremuloides)-mixed conifer types in Idaho [5], and in Douglas-fir habitats in western Montana [7]. American dragonhead was present in 4-year-old and 29-year-old burns in pinyon (Pinus spp.)-juniper (Juniperus spp.) habitats in Colorado, but cover was sparse [10]. It played an important role in early succession after severe fires in fir (Abies spp.)-spruce (Picea spp.) habitats in Grand Teton National Park, Wyoming, but disappeared within 43 postfire years [2]. American dragonhead had greater density in moderately-burned stands compared to severely-burned lodgepole pine (Pinus contorta) stands in Yellowstone National Park [1]. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : NO-ENTRY
