SPECIES: Ilex vomitoria
WOOD PRODUCTS VALUE : The wood of yaupon is heavy, hard, strong, and close grained. It is sometimes used for turnery, inlay work, and woodenware [38]. IMPORTANCE TO LIVESTOCK AND WILDLIFE : Yaupon fruit and seed are eaten by a variety of animals such as wild turkey, racoon, squirrel, and wild hog [10,14,33]. Yaupon leaves are a high choice browse of white-tailed deer [10]. PALATABILITY : The leaves of yaupon are considered highly palatable to white-tailed deer [10]. NUTRITIONAL VALUE : Percent dry weight nutrient values for yaupon are as follows [18]. spring summer fall winter protein 9.36 8.71 8.85 6.94 fat 3.09 3.12 3.67 4.84 fiber 17.33 26.69 21.85 21.62 N-free extract 46.34 42.40 46.34 48.53 ash 8.88 4.07 4.28 3.07 phosphorus 0.11 0.07 0.06 0.07 calcium 0.27 0.23 0.62 0.41 COVER VALUE : NO-ENTRY VALUE FOR REHABILITATION OF DISTURBED SITES : Because of yaupon's ability to survive the combined effects of salt spray, constant wind, full sunlight, and high temperatures, it has been planted on the beaches and dunes of the Southeastern Coastal Plain [4,14]. In Texas, yaupon was planted to restore borrow pits for wildlife use [22]. OTHER USES AND VALUES : Yaupon leaves were used by Native Americans for their emetic and purgative qualities [38]. Yaupon is often cultivated as an ornamental because of its bright red berries and evergreen leaves [38]. It is used extensively for hedges and is also planted on seaside resorts [14,39]. OTHER MANAGEMENT CONSIDERATIONS : Yaupon is undesirable in understories of southern pine plantations. It competes with pine seedlings and contributes to an accumulation of understory fuels, which increases the potential for wildfires [12,23,34]. Aerial applications of tebuthiuron were found to control yaupon and other hardwoods effectively in eastern Texas [19,25].


SPECIES: Ilex vomitoria
GENERAL BOTANICAL CHARACTERISTICS : Yaupon is an erect, slow-growing, native evergreen shrub or small tree. It forms dense thickets about 25 feet (8 m) tall. Many stems ascend from the base, forming a low, dense, rounded crown [9]. The thick evergreen leaves are simple, alternate, leathery, and vary in size and shape on the different plants. The inconspicuous flowers are dioecious and are borne in short-stalked axils at the base of the leaves. The bark is thin, gray, and smooth. The small, shiny red fruit is a drupe [6,36,38]. RAUNKIAER LIFE FORM : Phanerophyte (microphanerophyte) Phanerophyte (nanophanerophyte) REGENERATION PROCESSES : Yaupon reproduces sexually, and vegetatively by root sprouting [9,38]. Details on the regenerative processes of this species are lacking. Birds are the primary mode of seed dispersal [31]. SITE CHARACTERISTICS : Yaupon grows best in climates with mild winters and long, hot, humid summers. It is found on coastal dunes, maritime forests, upland woodlands of various mixtures, and pine flatwoods. For the most part, yaupon inhabits well-drained sites but also occurs on streambanks, in wet woodlands, and floodplains. Yaupon commonly forms shrub thickets on coastal dunes where it is a component of the slanting, salt-spray-pruned, dense masses of shrubs characteristic of seaside communities [6,9,29,32]. Common overstory associates include flowering dogwood (Cornus florida), sweetgum (Liquidambar styraciflua), sweetbay (Persea borbonia), blackgum (Nyssa sylvatica), sassafras (Sassafras albidum), loblolly-bay (Gordonia lasianthus), hickory (Carya spp.), and oak (Quercus spp.). Understory associates include American beautyberry (Callicarpa americana), southern bayberry (Myrica cerifera), swamp fetterbush (Leucothoe racemosa), greenbrier (Smilax spp.), and poor-man's soap (Clethra alnifolia) [3,4,21,24]. SUCCESSIONAL STATUS : Yaupon occurs in early- to mid-seral communities. It grows best in sunny sites but also grows well in light shade [26]. Young [41] describes yaupon as an early invader in south-central Texas rangelands. SEASONAL DEVELOPMENT : Yaupon flowers from April through May, and its fruit ripens in September and October [1].


SPECIES: Ilex vomitoria
FIRE ECOLOGY OR ADAPTATIONS : Yaupon is only moderately well adapted to fire [28,30]. Presumably, it survives fire by sprouting from the root crown. Dense thickets of yaupon are a primary fuel source, promoting fire spread in many parts of the Southeast [23,37]. POSTFIRE REGENERATION STRATEGY : survivor species; on-site survivng root crown or caudex off-site colonizer; seed carried by animals or water; postfire year 1&2


SPECIES: Ilex vomitoria
IMMEDIATE FIRE EFFECT ON PLANT : Mild fires probably top-kill yaupon [5,11,15]. Yaupon may be killed by fires severe enough to consume the soil's organic layer. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : Sprouting and increased fruit production in yaupon following fire have been reported, but details have not been described [13,28]. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : A fire management program that precludes a build up of understory yaupon is recommended [11,40]. In Kisatchie Hill Wilderness of Louisana, crown scorch of pine resulting from 25- to 30-foot (7.5-12 m) flame heights was associated with the combustion of understory yaupon. The size and density of yaupon was a result of 30 years of fire exclusion in the area [23].
