disturbances, a seral sugarberry-American elm (Ulmus americana)-green

sugarberry as a codominant. This type intermixes with sweetgum
(Liquidambar styraciflua)-willow oak (Quercus phellos) types, which
contain essentially the same species in different densities. The
sugarberry-American elm-green ash type occurs most often on the central
coastal plain of the Gulf of Mexico, heavily concentrated on the
Mississippi alluvial plain, and along major river basins [

Management considerations
provided by Fire Effects Information System Plants
More info for the terms:
basal area,
presence,
treeIn dense even-aged stands, sugarberry will self-prune and produce a
straight stem [
5].
In cottonwood (Populus spp.) stands on alluvium, sugarberry (usually
with poor growth forms) will take over openings created when cottonwoods
are cut, and control sites that managers would prefer to be in more
valuable species [
30]. On a site that was logged then seeded with Nuttall
oak (Quercus nuttallii), sugarberry (probably carried in by animals)
naturally established in sufficient numbers to make up one of four species
accounting for 83 percent of stems [
33,
39].
Sugarberry is susceptible to damage by ice, which breaks main stems and
branches [
5].
Defoliation of sugarberry by hackberry butterfly (Asterocampa celtis)
has been reported, though no tree death or crown die-back was observed.
Hackberry butterfly can be controlled by spraying trees with
insecticides [
5].
Sugarberry is used as an ornamental, even though leaf leachate can
reduce growth of grasses under the trees due to the presence of ferulic,
caffeic, and p-coumaric acids [
5].
Good stands of sugarberry are able to establish naturally after logging
[
22]. In a study of logging practices in Mississippi, sugarberry
reached the highest densities in regeneration after all sawtimber-sized
stems were removed and either all stems greater than 2 inches in d.b.h.
(5 cm) were injected with 2,4-D or stems of desirable species left
untreated with 2,4-D. Sugarberry was considered a desirable species in
this study [
29]. Seven years after clearcutting on a site where
sugarberry was a canopy dominant, sugarberry accounted for 32 percent of
total regeneration stems [
23]. After patch clearcutting, sugarberry
dominated both sapling and seedling regeneration on a site where, prior
to harvest, it had been second in basal area (after sweetgum) [
25].
Sugarberry has no major diseases of the twigs and leaves, but eastern
mistletoe (Phoradendron flavescens) may cause serious damage in the
western part of sugarberry's range [
5].

Climate
provided by Silvics of North America
Sugarberry grows in a humid climate except for part of its range
in Oklahoma and Texas which lies west of a north-south line
through Galveston Bay. There the climate is semihumid to
semiarid. The average precipitation varies from 510 to 1520 mm
(20 to 60 in) per year, the lightest being in central Texas and
Oklahoma. An average of 380 to 760 mm (15 to 30 in) occurs during
the frost-free period. Annual snowfall ranges from 0 to 51 cm (0
to 20 in).
Summer temperatures vary from an average of 27° C (80°
F) to extremes of 46° C (115° F). Average winter
temperatures are from -1° to 10° C (30° to 50°
F), with an extreme of -29° C (-20° F).
The average length of the growing season varies from 150 to 270
days.

Damaging Agents
provided by Silvics of North America
The bark is thin and easily injured by
fire. A light burn kills back reproduction. Heavier bums may kill
even the largest trees and wound others, making them subject to
serious butt rot, which in sugarberry advances rapidly. Butt rot
is a common name used to indicate the area of the decay in the
butt log which may be caused by any one of 30 or more species of
fungi belonging to the genera Fomes, Polyporus, Hericium,
and Plyeurotus.
Ice also causes heavy damage to the crowns, breaking the main stem
and branches which reduces growth and creates wounds that allow
entrance of rot-causing fungi. There are some other diseases of
the twigs and leaves, but none are of major importance.
Eastern mistletoe (Phoraedendron flavescens) may cause
serious damage in the western part of its range (7). A number of
scales attack the twigs, small branches, and sometimes the
trunks, but none are considered very damaging. Leaf petiole galls
caused by the hackberry petiole gall maker (Pachypsylla
venusta) are common. In recent years, defoliation of large
acreages in several Southern States by larvae of the hackberry
butterfly (Asterocampa celtis) have been reported (12).
No deaths or crown die-back among the trees was observed in the
following years. Research has shown that the hackberry butterfly
can be controlled by spraying trees with certain registered
insecticides (8).

Flowering and Fruiting
provided by Silvics of North America
The small, greenish flowers appear
with the leaves in the early spring-from mid-March to May,
depending on latitude (1). Sugarberry is polygamo-monoecious. The
fruit ripens in September and October, and often remains on the
trees until midwinter. Sugarberry fruits are spherical drupes 6
to 13 mm (0.25 to 0.5 in) in diameter with a thin pulp enclosing
a single bony nutlet. Late spring frosts sometimes kill the
flowers and reduce the seed crop.

Genetics
provided by Silvics of North America
Sugarberry seems to present a considerable number of local
variations that have prompted some botanists to name a number of
varieties, while other botanists feel the distinctions are too
slight to warrant such status (13).
Some varieties listed are Texas sugar hackberry, C. laevigata
var. texana; Uvalde sugar hackberry, C. laevigata
var. brachyphylla; scrub sugar hackberry, C.
laevigata var. anomala; small sugar hackberry, C.
laevigata var. smallii; Arizona sugar hackberry, C.
laevigata var. brevipes; net-leaf sugar hackberry,
C. laevigata var. reticulata.
There are no known races or hybrids of sugarberry.

Growth and Yield
provided by Silvics of North America
Sugarberry is a small- to medium-sized
tree. It often attains a height of 24 to 30 in (80 to 100 ft) at
maturity. On best sites, 10-year diameter growth can be in excess
of 6 cm (2.5 in) for dominant trees (9). The overall average is
about 2.5 to 5 cm (1 to 2 in) in 10 years. On average sites,
mature forest-grown trees average about 46 cm (18 in) in diameter
and 24 in (80 ft) in height, with trunks clear of branches for
approximately 9 m (30 ft).
An accurate estimate of the total growing stock is available for
only a limited portion of the sugarberry range. Because of its
scattered occurrence, forest surveys usually include sugarberry
in a group of other species with limited frequencies. The only
region containing enough sugarberry of sawtimber size to list
separately is the Mississippi Delta (10). The principal States
producing commercial quantities of sugarberry are Louisiana,
Mississippi, and Arkansas. These States contain about 16 million
m³ (560 million ft³) and about 9.4 million m³
(1,650 million fbm) of sugarberry sawtimber. In 1965, a rough
estimate of the total sawtimber resource in the United States was
in excess of 10.0 million m' (2,000 million fbm).

Reaction to Competition
provided by Silvics of North America
Sugarberry is classed as tolerant
of shade. It grows fast when released and often outgrows more
desirable forest species (5). Sugarberry becomes established in
the understory and generally has very poor form in this
situation. In dense, even-aged stands, however, it prunes itself
well and produces a straight stem.

Rooting Habit
provided by Silvics of North America
Sugarberry is a relatively shallow-rooted
tree and does not develop a distinct taproot. The root system is
saucer-shaped with good lateral root development. The tree is
about average in resistance to windthrow.

Seed Production and Dissemination
provided by Silvics of North America
Seed production starts
when trees are about 15 years old (7). Optimum seed-bearing age
is from 30 to 70 years old. Sugarberry bears good seed crops in
most years and some nearly every year. There are between 4,400
and 5,300 cleaned seeds per kilogram (2,000 to 2,400/lb). The
seed is widely dispersed by birds and water.
Mature fruits can be picked by hand from trees as late as
midwinter. Collection is easier after trees have completely
dropped their leaves. Branches of sugarberry can be flailed to
knock the fruits onto sheets of plastic or other suitable
material spread under the trees.
If seeds are to be used for seedling production in a nursery, then
both fall sowing of untreated seeds and spring sowing of
stratified seeds are satisfactory. Seeds may be broadcast or
drilled in rows and should be covered with 6 to 13 mm (0.25 to
0.5 in) of firmed soil. Beds should be covered with bird screens
until germination starts. Experience at the Southern Hardwoods
Laboratory, Stoneville, MS, has shown that if spring sowing is
used, the seeds should be depulped before storage, dried to 8 to
10 percent moisture content, and stored in 6-mil-thick plastic
bags or equivalent storage containers until stratification. Seeds
should be stratified in moist sand or other suitable media for 60
to 90 days before sowing in the nursery. The seeds can be
depulped by wet maceration. Depulping is not essential, but it
has been reported to aid germination (1). Average germinative
capacity is reported to be 55 percent for sugarberry.

Seedling Development
provided by Silvics of North America
Sugarberry seeds lie dormant over
winter and germinate early in the spring. Germination is epigeal
(1). The seedlings become established under most stands of
southern bottom land hardwoods. Best natural conditions for
germination are moist, loamy soil, but the species is found
mostly on clay soils. First-year growth usually produces a very
slender but tough stem, 20 to 46 cm (8 to 18 in) in height. Under
shade, the young seedling develops a crooked, short stem, often
forked within a few feet of the ground. In the open, it tends to
be very limby and short boled. Sugarberry is considered
intolerant of flooding, at least in the seedling stage (2,3,4).

Soils and Topography
provided by Silvics of North America
Sugarberry is most common on Inceptisols and Entisols found in
broad flats or shallow sloughs within flood plains of major
southern rivers (9), but will grow under a considerable range of
soil and moisture conditions. It is widely distributed on bottom
lands except in deep swamps and is found to a minor extent on
upland sites. It is also common on deep moist soils derived from
limestones, notably in the Black Belt of Alabama (10).

Special Uses
provided by Silvics of North America
Sugarberry mixed with hackberry supplies the lumber known as
hackberry. Small amounts are used for dimension stock, veneer,
and containers, but the main use of sugarberry wood is for
furniture. The light-colored wood can be given a light- to
medium-brown finish that in other woods must be achieved by
bleaching.
The dry sweet fruit is eaten by at least 10 species of birds, as
well as other game and nongame animals (13).
Sugarberry is often used for street planting in the lower South
and is also used as an ornamental in residential areas. A problem
in such use is that leachates from the leaves reduce germination
and growth of a number of grasses under the trees (6). These
leachates have been identified in the soil as ferulic acid,
caffeic acid, and p-coumaric acid.

Brief Summary
provided by Silvics of North America
Ulmaceae -- Elm family
Harvey E. Kennedy, Jr.
Sugarberry (Celtis laevigata), a common medium-size tree of
moderate to fast growth, is most often found on clay soils of
broad flats or shallow sloughs within the flood plains of major
southern rivers. It is also called sugar hackberry, hackberry,
Texas sugarberry, southern hackberry, and lowland hackberry.
Sugarberry is short lived, probably not living more than 150
years. The wood is of medium strength and hardness and much of
the light yellow wood is used by furniture manufacturers. The
abundant crops of fruits are eaten by wildlife, especially birds.
The tree is planted as an ornamental and as a street tree in
residential areas in the lower South.

Mississippinældetræ
(

)
provided by wikipedia DA
Mississippinældetræ (Celtis laevigata) er et middelstort, løvfældende træ, der hører hjemme i Nordamerika.
Mississippinældetræet kan nemt forveksles med amerikansk nældetræ (C. occidentalis). Mississippinældetræet har smallere blade, der er blødere på oversiden. De to arter kan også skelnes på habitat: i de områder, hvor arterne begge findes, vokser det amerikanske nældetræ højere oppe, mens mississippinældetræet vokser i lavereliggende områder.
Økologi
Bladene er føde for en række insekter, fx larver af møl-arten Automeris io.
Træet blomstrer i maj og har orange, gule eller mørkerøde frugter på 0,6 cm.[2]
Førnen fra træet indeholder allelopatiske kemikalier, der hæmmer frøspiring og trivsel i mange andre plantearter.[1]
Hjemsted
Arten vokser langs vandløb og i blødt jord på flodsletter. Udbredelsesområdet er i det sydøstlige USA vestpå til Texas og det nordligøstlige Mexico.[3] Desuden vokser træet på Bermuda.[4]
Kultivering og anvendelse
Veddet fra mississippinældetræet bruges til tømmer, der især anvendes til møbelproduktion. Det lyse ved kan tilføjes en lys- eller mellembrun finish, som hos andre træsorter kun kan opnås ved blegning.[5] Træet bruges også til at fremstille sportsartikler og krydsfiner.
Træet plantes ofte som skyggetræ. Det trives fint i bymæssige områder, og dets elmeagtige form og vortede bark gør det velegnet til formning af landskaber.

Celtis laevigata, Southeastern Louisiana.
Celtis laevigata is a medium-sized tree native to North America. Common names include sugarberry, southern hackberry, or in the southern U.S. sugar hackberry or just hackberry.
Sugarberry is easily confused with common hackberry (C. occidentalis) where the range overlaps. Sugarberry has narrower leaves with mostly smooth margins, the berries are juicier and sweeter, while the bark is less corky.[3] The species can also be distinguished by habitat: where the ranges overlap, common hackberry occurs primarily in upland areas, whereas sugarberry occurs mainly in bottomland areas.[3]
Sugarberry's range extends from the Eastern United States west to Texas and south to northeastern Mexico.[2] It is also found on the island of Bermuda.[4]
Ecology
Sugarberry occurs primarily along streams and in moist soils on floodplains. Its sweetish fruit is eaten by birds and rodents,[5] helping to disperse the seeds.[6] The leaves are eaten by a number of insects, for example caterpillars of the Io moth (Automeris io).
Sugarberry's leaf litter contains allelopathic chemicals that inhibit seed germination and growth in many other plant species.[7]
Cultivation and uses
Sugarberry mixed with hackberry supplies the lumber known as hackberry. Small amounts are used for dimension stock, veneer, and containers, but the main use of sugarberry wood is for furniture. The light-colored wood can be given a light- to medium-brown finish that in other woods must be achieved by bleaching.[8] The wood is also used to produce sporting goods and plywood.[9]
Sugarberry is frequently planted as a shade-tree within its range. It is well-adapted to urban areas; its elm-like shape and warty bark make it an attractive landscape tree.

Celtis laevigata, el almez del Mississippi[1] o palo blanco es una especie de planta de flores perteneciente a la familia Cannabaceae. Nativa del sur de Norteamérica, principalmente en Texas.
Descripción
Son árboles de tamaño medio que fácilmente se confunde con (Celtis occidentalis) por sus semejanzas. Celtis laevigata tiene las hojas más estrechas y dentadas arriba. Las especies se distinguen también por su hábitat: ya que este crece en zonas de montaña y C. occidentalis lo hace principalmente en tierras bajas.
Hábitat
Crece cerca de los arroyos y en suelos inundados. Sus frutos son el alimento de pájaros que dispersan sus semillas. Sus hojas son comidas por gran número de insectos como orugas.
Propiedades
Sus hojas contienen sustancias químicas que inhibe la germinación de otras especies de plantas.[2]
Usos
Los frutos son comestibles y dulces, el sabor es similar al de los dátiles, pero el hueso es grande y está cubierto solo por una fina capa de carne.Se diferencia del árbol de hackberry común (Celtis occidentalis), entre otras cosas, en los frutos son más jugosos y dulces.
Los nativos americanos usaban este árbol como alimento, medicinas, herramientas y combustible. Las bayas eran consumidas por los nativos americanos; Los Houma usaban un concentrado hecho de la corteza para tratar los dolores de garganta y la decocción hacía de la corteza triturada las cáscaras para tratar las enfermedades venéreas; los Navajo hervían las hojas y las ramas para hacer un tinte marrón oscuro y rojo para la lana.
Taxonomía
Celtis laevigata fue descrita por Carl Ludwig Willdenow y publicado en Enumeratio Plantarum Horti Botanici Berolinensis, . . . suppl.: 68. 1814.[3]
- Etimología
Celtis: nombre genérico que deriva de céltis f. – lat. celt(h)is = en Plinio el Viejo, es el nombre que recibía en África el "lotus", que para algunos glosadores es el azufaifo (Ziziphus jujuba Mill., ramnáceas) y para otros el almez (Celtis australis L.)[4]

Celtis laevigata er et løvfellende tre i hampfamilien. Det ble tidligere regnet til almefamilien.
Det blir 24–30 m høyt. Barken er lysegrå og er glatt eller dekket av vorter. Bladene er smalere, som regel helrandet og ikke så ru som hos slektningen amerikanesletre (C. occidentalis). De små, grønne blomstene kommer samtidig med løvsprett. Frukten er en steinfrukt som er 6–13 mm stor og oransje til brun eller rød når den er moden.
Celtis laevigata trives på leirjord og vokser på slettene langs store elver i de amerikanske sørstatene. Her danner den skog sammen med andre trær som virginiapoppel, ambratre, pileik, vasseik, amerikaplatan, kvitalm, grønnask, alm, sumptre, Diospyros virginiana, korstorn, rødlønn, asklønn, Forestiera acuminata og hagtorn.
Utbredelsen strekker seg fra sørøstre Virginia til sørlige Florida, vestover til sentrale Texas og nordover til vestlige Oklahoma, sørlige Kansas, Missouri, sørlige Illinois, sørlige Indiana og vestlige Kentucky. Spredte forekomster finnes på Bermuda og i Maryland, Rio Grande-dalen og nordøstlige Mexico. Lenger nord erstattes den av amerikanesletre, men utbredelsene overlapper.
