ABBREVIATION : EUPCAP SYNONYMS : Eupatorium compositifolium Walt. SCS PLANT CODE : EUCA5 COMMON NAMES : dogfennel TAXONOMY : The currently accepted scientific name for dogfennel is Eupatorium capillifolium (Lam.) Small (Asteraceae) [2,6]. Eupatorium compositifolium Walt. and E. leptophyllum D.C. are closely related species which some authors include as varieties of E. capillifolium [2,11]. There are no recognized subspecies or varieties. LIFE FORM : Forb FEDERAL LEGAL STATUS : No special status OTHER STATUS : NO-ENTRY


SPECIES: Eupatorium capillifolium
GENERAL DISTRIBUTION : Dogfennel grows in the southeastern United States from southern Florida west to eastern Texas. Its range extends north to Tennesee, Virginia, and New Jersey. It is occasional farther north along the East Coast to Massachusetts [2].

SPECIES: Eupatorium capillifolium
IMPORTANCE TO LIVESTOCK AND WILDLIFE : Dogfennel has no value as forage for wildlife and livestock [9,15]. PALATABILITY : Dogfennel probably has very low palatability. Cattle graze it sparingly if at all, even when other forage is scarce [9]. NUTRITIONAL VALUE : NO-ENTRY COVER VALUE : NO-ENTRY VALUE FOR REHABILITATION OF DISTURBED SITES : NO-ENTRY OTHER USES AND VALUES : NO-ENTRY OTHER MANAGEMENT CONSIDERATIONS : Dogfennel may serve as a reservior for disease-causing pathogens when growing among food crops [4]. Dogfennel is scarce on forest ranges in good condition [9]. Grazing forage utilization in excess of 65 percent will favor dogfennel establishment [3]. Dogfennel presence may indicate overgrazing.


SPECIES: Eupatorium capillifolium
GENERAL BOTANICAL CHARACTERISTICS : Dogfennel is a common, aggressively weedy native of the southeastern United States [2,14]. It is alternately described as an annual [2,9,16] and a perennial [6,14]. It has several stems arising from a stout woody caudex. It grows in distinct colonies on favorable sites. Dogfennel normally reaches 4 to 5 feet (1.2-1.5 m) in height but can reach up to 9 feet (2.7 m) on fertile sites [9]. The fruit is a smooth achene [9]. RAUNKIAER LIFE FORM : Hemicryptophyte Therophyte REGENERATION PROCESSES : Dogfennel is wind pollinated [9]. Following the typical pattern of weedy plants, dogfennel's primary mode of regeneration is probably sexual. Its regeneration strategy probably depends on the production of a great many wind-dispersed seeds. SITE CHARACTERISTICS : Dogfennel grows on disturbed sites in the Southeast. It is common on young burns in the loblolly pine (Pinus taeda)-turkey oak (Quercus laevis) type in Florida's Ocala National Forest [10], on recent burns in the Okefenokee Swamp [1], on burned and cut Atlantic white-cedar (Chamaecyparis thyoides) sites in the Great Dismal Swamp [14], and on overgrazed sites in Louisiana [3]. Dogfennel is a frequent invader of everglades sawgrass (Cladium sp.) communities during drought [7,13]. Other dogfennel sites include meadows, swales, old fields, pond borders, ditches, disturbed or overgrazed pastures, and roadsides [9]. Although apparently able to grow on a variety of soils, it is most common on dry, sandy soils [9]. SUCCESSIONAL STATUS : Obligate Initial Community Species Dogfennel is intolerant of closed or highly structured communities [9]. It is undoubtedly an early seral, if not an invader, species in most successional progressions within its range. SEASONAL DEVELOPMENT : Dogfennel biomass peaks in the spring [14]. Its flowering period is unusually long because shaded plants bloom earlier than those in full sun. A population of dogfennel near Gainsville Florida had the following phenological sequence [3]. Phenological event Timing ------------------ ----------------------------- Flowering late August - early November Fruit ripening early - mid November Fruit dispersal late November - early December Drying late November - mid January Dormancy mid January - early March Bolting early April - June


SPECIES: Eupatorium capillifolium
FIRE ECOLOGY OR ADAPTATIONS : The fire ecology of dogfennel has not been adequately described. Dogfennel probably depends on off-site seed sources to colonize recently burned areas. Sprouting from a surviving caudex may also occur. POSTFIRE REGENERATION STRATEGY : NO-ENTRY


SPECIES: Eupatorium capillifolium
IMMEDIATE FIRE EFFECT ON PLANT : Most fires probably kill or at least top-kill dogfennel. Its caudex may survive cool fires. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : The presence of dogfennel on recently burned sites [1,10,14] indicates that seedling establishment and/or sprouting occurs following fire. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : NO-ENTRY
