MANAGEMENT CONSIDERATIONS
SPECIES: Liriodendron tulipifera
WOOD PRODUCTS VALUE:
Tuliptree wood is used for construction grade lumber and plywood
[1]. It has straight grain, little shrinkage, and excellent gluing
qualities [2]. In the past is was used for carriage bodies, shingles,
saddle frames, and interior finish wood. It is currently used for
cabinets, veneer, furniture, and pulp [2]. Tuliptree has only fair
value as a fuelwood but good value as kindling [4].
IMPORTANCE TO LIVESTOCK AND WILDLIFE:
Livestock prefer the foliage and stems of tuliptree over those of
other tree species. Young trees are often heavily browsed, and
seedlings are frequently eliminated by browsing or trampling [1].
Cattle or other browsers create "browse lines" on older trees [2].
White-tailed deer browse tuliptree during all seasons [23].
Northern bobwhites, purple finches, cottontails, red squirrels, gray
squirrels, and white-footed mice consume the samaras [2].
Yellow-bellied sapsuckers use the phloem, and ruby-throated hummingbirds
consume nectar from the flowers [21].
PALATABILITY:
Tuliptree has been rated fair in palatability for livestock,
white-tailed deer, small mammals, upland game birds, and songbirds [4].
NUTRITIONAL VALUE:
NO-ENTRY
COVER VALUE:
Tuliptrees in various stages of growth provide hiding and thermal
cover for white-tailed deer, small mammals, upland game birds,
waterfowl, and nongame birds [21]. They provide habitat for the
endangered red-cockaded woodpecker [15].
VALUE FOR REHABILITATION OF DISTURBED SITES:
Tuliptree has been planted onto surface coal mine reclamation sites
with variable results, but total failures are rare [7,29]. One-year-old
seedlings planted on sites in Kentucky and Illinois showed good survival
rates (24 percent) for 30 years after planting. Tuliptree should be
planted in mixtures with other hardwoods. Tuliptree growth under
decadent black locust (Robinia pseudoacacia) in Indiana was good. In
eastern Kentucky height growth nearly doubled when tuliptree was
interplanted with European alder (Alnus glutinosa) [29]. One-year-old
seedlings are recommended for planting [29].
The lower pH limit for tuliptree on acid mine spoils is 4.5 [29].
Liming the spoils before planting has improved tuliptree
establishment on acid spoils in Pennsylvania [14].
OTHER USES AND VALUES:
Tuliptree has been valued as an ornamental since 1663. The
tuliplike flowers and leaves are aesthetically pleasing [2]. The
flowers are also valuable nectar producers. The flowers from a
20-year-old tree produce enough nectar to yield 4 pounds (1.8 kg) of
honey [1].
Tuliptree was used medicinally in the late 1800's: a heart
stimulant was extracted from the inner bark of the root [13], and a
tonic for treating rheumatism and dyspepsia was extracted from stem bark
[28].
OTHER MANAGEMENT CONSIDERATIONS:
Insects: Compared with other commercial species, tuliptree is
relatively free of pests. Only four insect species have important
impact on harvest. Tuliptree scale (Toumeyella liriodendri) and
tuliptree weevil (Odontopus calceatus) feed on the buds and stems.
Root collar borer (Euzophera ostricolorella) and Columbian timber beetle
(Corthtlus columbianus) bore into the bole and root crown, providing
pathways for other pathogens to enter the tree. The Columbian timber
beetle also lowers lumber grade by creating a large black streak above
and below beetle burrow entries [1,2,24].
Silviculture: Clearcutting is the recommended harvest method for
tuliptree. Its seeds survive for 4 to 8 years on the forest floor,
making seed tree cuts unnecessary [6]. When tuliptree is harvested
in warm seasons, the wood is susceptible to a wood-staining fungi
(Ceratocystis spp.) which lowers the lumber grade. Rapid processing of
the logs in warm seasons reduces monetary losses from staining [2].
Season of harvest can have an impact on establishment and growth of
tuliptree seedlings. In stands logged in late spring or summer,
seeds may not germinate until the following year; these seedlings may
not be able to compete with vegetation started the previous year.
However, where a good seed source was previously present, summer
cuttings usually produce an adequate number of seedlings. If the seed
supply in the litter is scarce, fall, winter, or early spring harvesting
may aid in seedling establishment [2].
Tuliptree is shade intolerant and responds well to overstory
thinning. Tuliptree was four times taller and five times larger in
dbh in an 18-year-old stand where all the overstory vegetation had been
removed than in the control [2]. Lamson [18] has provided information
on thinning. Tuliptree responds well to fertilization. It grew
twice as tall on sites fertilized with diammonium phosphate at a rate of
500 pounds per acre (562 kg/ha) than on control sites [10].
Pollution: Tuliptree is very sensitive to high ozone concentrations [8].

GENERAL BOTANICAL CHARACTERISTICS:
Tuliptree is a tall, deciduous, long-lived, broadleaf tree. The
leaves are alternate with a distinctive tuliplike shape. In forest
stands tuliptree is one of the straightest and tallest trees, with
approximately 66 percent of the bole free of lateral branches [1,2]. It
can reach heights of 200 feet (61 m) and a dbh greater than 10 feet (3
m) [13]. The flowers are tuliplike in size and shape [1,2,11]. The
fruit is a conelike structure consisting of many winged samaras on a
central stalk [2].
RAUNKIAER LIFE FORM:
Phanerophyte
REGENERATION PROCESSES:
Tuliptree is mainly insect pollinated, with some selfing. It a
prolific seed producer. It first produces seed at 15 to 20 years of age
and continues to do so for more than 200 years [1]. Heavy seed crops
tend to compensate for low seed viability (around 5-20 percent) [26].
The samaras are wind dispersed to distances 4 and 5 times the height of
the parent tree. The samaras remain viable in the seedbank for up to 8
years [5,16,19]. Seeds require a cold stratification period, and
germination rates vary with time and temperature. Generally as
temperature decreases and time increases the germination rate increases;
for example, 90 percent germination occurred after 140 days at 36
degrees Fahrenheit (2 deg C) [1,3]. Germination is epigeal and occurs
when seeds remain constantly moist for several weeks [3,5]. Germination
is enhanced on mineral soil or on well-decomposed humus [2].
Tuliptree sprouts from dormant buds located on the root crown after
cutting and/or fire. Sprouting decreases with age, as the bark becomes
too thick for the bud to break through [2,16]. Initially sprout growth
surpasses seedling growth, but at 25 to 35 years seedling regeneration
height catches and surpasses sprout regeneration height [2].
SITE CHARACTERISTICS:
Tuliptree grows best on north and east aspects, lower slopes,
sheltered coves, and gentle concave slopes [1,27].
Soils: Growth is best on moderately deep loams that are moderately
moist, well drained, and loose textured [1,27].
Associated species: Overstory associates include baldcypress (Taxodium
distichum), tupelo (Nyssa spp.), loblolly pine (Pinus taeda), shortleaf
pine (P. echinata), eastern white pine (P. strobus), oaks (Quercus
spp.), white ash (Fraxinus americana), American beech (Fagus
grandifolia), black walnut (Juglans nigra), and hickory (Carya spp.)
[1,2].
Climate: Tuliptree grows under a variety of climatic conditions due
its broad geographic distribution. The average rainfall varies from 30
to 80 inches (760-2030 mm), and the number of frost-free days varies from
150 to 310 days [1].
Elevation: Tuliptree grows near sea level in Florida to 4,500 feet
(1,364 m) in the Appalachian Mountains [3].
SUCCESSIONAL STATUS:
Tuliptree is a shade-intolerant, pioneer species. It often invades
open sites, and in old-field succession it occurs in pure or nearly pure
stands [1,16].
SEASONAL DEVELOPMENT:
Yellow poplar flowers from April to June; seeds mature from August to
late October. Peak samara dispersal is from October to November, with a
few falling as late as March [2,26].
FIRE ECOLOGY
SPECIES: Liriodendron tulipifera
FIRE ECOLOGY OR ADAPTATIONS:
Mature tuliptrees have bark sufficiently thick (> 0.5 inch [1 cm])
to insulate the cambium layer and allow trees to survive low- to
moderate-severity fire. Trees top-killed by fire sprout from dormant
buds located on the root crown [2]. Fire can enhance tuliptree
seedling establishment [31].

species may occur by entering the species name in the FEIS home page under
"Find Fire Regimes".
POSTFIRE REGENERATION STRATEGY:
Tree with adventitious-bud root crown/soboliferous species root sucker
Ground residual colonizer (on-site, initial community)
Secondary colonizer - off-site seed
FIRE EFFECTS
SPECIES: Liriodendron tulipifera
IMMEDIATE FIRE EFFECT ON PLANT:
Tuliptree seedlings and saplings have thin bark which makes them
very susceptible to fire damage. Fire generally kills young trees less
than 1 inch (2.5 cm) in diameter. Once bark is thick enough to insulate
the cambium (0.5 inch [1.3 cm]), tuliptree becomes extremely
resistant to fire damage [1,2]. Little mortality occurs once trees are
greater than 3 or 4 inches d.b.h. [31]. Tuliptree seeds are
generally resistant to heat damage [31].
DISCUSSION AND QUALIFICATION OF FIRE EFFECT:
Compared with other hardwoods, tuliptree is relatively resistance to
fire-damage-induced decay. A study comparing wound size with amounts of
bark discoloration found that tuliptrees were more resistant to
wounding than oaks. Even when large amounts of bark were discolored,
larger diameter tuliptrees developed only small wounds [31].
Several studies have determined that within a given size class,
tuliptree is generally more resistant to fire damage than oaks [31].
PLANT RESPONSE TO FIRE:
Sprouting: Tuliptree sprouts from the root crown following top-kill
by fire [2,16].
Seedling establishment: Prescribed fire enhances the regeneration of
tuliptree by releasing seed stored on the forest floor [31].
Following fall prescribed fire in the Upper Piedmont of South Carolina,
the number and height growth of tuliptree seedlings were
significantly higher on burned than on unburned plots. After one
growing season, the burned plots had about 12,000 seedlings per acre;
the unburned, 2,000. After three growing seasons, seedlings on the
burned plots averaged 3.5 feet (1.06 m) in height; seedlings on the
unburned plots averaged 3.0 feet (0.91 m) [26].
DISCUSSION AND QUALIFICATION OF PLANT RESPONSE:
While mature tuliptree is very fire resistant, the saplings are
susceptible to fire [1]. In a 5-year-old stand burned with varying
severities, the densities of saplings over 4.5 feet (1.4 m) in height 3
years (areas 1 and 3) and 2 years (areas 2 and 4) after fire had
decreased significantly from prefire densities. Sapling densities
(stems/acre) were as follows [22]:
Area 1 Area 2 Area 3 Area 4
Burn Burn No Burn Burn
(Moderate) (Light) (Control) (Severe)
Saplings 709 74 677 294
Postfire change -438 -21 +23 -8
Severe basal wounding of 8- to 18-inch-diameter tuliptrees had no
significant effect on diameter growth rate 7 to 14 years after a fire
[31].

fire and postfire response of plant community species, including
tuliptree, that was not available when this species review was written:
