Wild Carrot is a very common plant that occurs in every county of Illinois (see Distribution Map). It is adventive from Europe and has existed in the United States for quite some time. Habitats include thickets, degraded prairies or meadows, areas along railroads and roadsides, lawns, pastures, abandoned fields, fence rows, vacant lots, junk yards, and other waste areas. Fire is not very effective in removing this plant from natural habitats, however it tends to decline in such habitats in the absence of disturbance.

Comments: It is often found on calcareous soil, but not restricted to it. It apparently prefers fine-particled soil and a high nutrient status, but endures a wide range of conditions (Dale 1974). Ahrenhoerster (pers. comm.) suggested that it may be more persistent on heavy soils with a good clay content. Gross and Werner (1982) stated that D. carota normally does not occur on newly abandoned fields because seeds do not survive for more than 1-2 years and are not often present in a newly disturbed area. Once dispersed to an area, the seedlings can emerge and survive in several types of ground cover, including those with thick vegetation. It is commonly found in fields 4-7 years after abandonment (Gross and Werner 1982).

Comments: Daucus carota populations have a large proportion of annuals under favorable conditions and low density. At high densities intraspecific competition causes plants to become less vigorous, flower late, and set fewer seeds. Flowering may be delayed to a third or fourth season if conditions are unfavorable (Dale 1974). Attacks by the nymphal stage of the plant bug, Lygus spp., on the seed destroys the seed embryo. Roots are eaten by carrot rust fly larvae (Psila rosae), and lesion nematode adults and larvae (Protyleachus spp.), and the root knot nematode (Meloidogyne spp.). The aster yellow fungus, a mycoplasm transmitted mainly by leaf hoppers (Macrostelos) can damage 25-90% of a wild carrot patch (Dale 1974).

Management Requirements: Daucus carota can be controlled along paths or in small patches by hand-pulling or mowing in mid-to-late summer before seed set. It is an early successional invader, but does not appear to significantly inhibit the establishment and recovery of native prairie species. Abundance in sandy soil generally declines on its own as natives become reestablished (Huffman, pers. comm.). It is more persistent in soils with a good clay content, and active management may be necessary in such areas (Ahrenhoerster, pers. comm.). It is particularly troublesome when it occurs on railroad and highway rights-of-way with heavy soils where frequent mowing keeps the area bare and, since incorrectly timed, simply allows for germination or scatters seeds. Ahrenhoerster (pers. comm.) recommended hand-pulling or mowing close to the ground in the first year of growth when plants are 7-10 inches high.
Management Programs: On the Kitty Todd Nature Preserve in Ohio, Daucus carota was abundant in 1985, on relatively bare soil of a field abandoned from cultivation just two years before. Mowing was considered, but by 1987, abundance had significantly decreased on its own. Contact: Mary Huffman, Manager and Research Associate, Kitty Todd Nature Preserve, 10270 Old State Line Rd., Swanton, OH 43558. 419-867-0619.
Daucus carota is more persistent on the heavier soils of southeastern Wisconsin. Ahrenhoerster (pers. comm.) recommended hand-pulling or mowing close to the ground in the first year of growth when plants are 7-10 inches high. Contact: Bob Ahrenhoerster, P.O. Box 83, Northlake, WI 53064. 414-673-5878.
Management Research Needs: The persistence of Daucus in prairies is apparently unknown. How well does it compete with native species for available resources? Is it a concern on good quality prairies? Is active management, other than encouraging good recovery of the native community, required? How does fire affect Daucus, and can prescribed burns enhance or deter its growth?

Global Range: Introduced and naturalized from Europe, Daucus carota inhabits dry fields and waste places at low altitudes throughout the northern United State from Vermont to Virginia west to Washington and California and north into Canada (Fernald 1951).
