Fire Management Considerations

More info for the term: forest

Since populations of devil's walkingstick are maintained only on
disturbed areas, periodic fires that create disturbed areas and forest
openings would result in seral sites that could include devil's walkingstick [15,16].

Management considerations

More info for the term: cover

Control:  Devil's walkingstick is killed by aerosol applications of
glyphosate at rates of 1.50 to 2.25 pounds per acre (0.56-2.52 kg/ha)
applied three times at 2-week intervals from mid-August to mid-September
[35].  Korostoff [17] reported that devil's walkingstick is controlled
by cutting and application of herbicide to the stump.  The most
effective treatment reported by Loftis [20] is injection of stems larger
than 2 inches in diameter with herbicide; basal sprays were ineffective
on his study sites.

Establishment:  Devil's walkingstick populations are maintained only on
disturbed sites.  When the overstory cover becomes thick enough, devil's
walkingstick declines.  Defoliation by gypsy moth infestation in
Pennsylvania and Maryland resulted in an increase in stems per acre of
devil's walkingstick, due both to injury of devil's walkingstick
ramets and to release by removal of overstory [12].  Mowing or cutting
of stems results in vigorous sprouting of new ramets from underground
rhizomes and is recommended for maintenance of vigorous stands [14,15].
Fire also produces appropriate disturbances and stem damage, and could
be used to maintain devil's walkingstick stands [36].

Aralia spinosa

provided by wikipedia EN

Aralia spinosa, commonly known as devil's walking stick, is a woody species of plant in the genus Aralia, family Araliaceae, native to eastern North America. The various names refer to the viciously sharp, spiny stems, petioles, and even leaf midribs. It has also been known as Angelica-tree.[1]

This species is sometimes called Hercules' club, prickly ash, or prickly elder, common names it shares with the unrelated Zanthoxylum clava-herculis. For this reason, Aralia spinosa is sometimes confused with that species and mistakenly called the toothache tree,[2] but it does not have the medicinal properties of Zanthoxylum clava-herculis.

Aralia spinosa is occasionally cultivated for its exotic, tropical appearance, having large lacy compound leaves. It is closely related to the Asian species Aralia elata, a more commonly cultivated species with which it is easily confused.

Description

Aralia spinosa is an aromatic spiny deciduous shrub or small tree growing 2–8 m (6.6–26.2 ft) tall, with a simple or occasionally branched stem with very large bipinnate leaves 70–120 cm (28–47 in) long. The trunks are up to 15–20 cm (5.9–7.9 in) in diameter, with the plants umbrella-like in habit with open crowns. The young stems are stout and thickly covered with sharp spines. The plants generally grow in clusters of branchless trunks, although stout wide-spreading branches are occasionally produced.[1]

The flowers are creamy-white, individually small (about 5 mm or 0.2 in across) but produced in large composite panicles 30–60 cm (12–24 in) long; flowering is in the late summer. The fruit is a purplish-black berry 6–8 mm (0.24–0.31 in) in diameter, ripening in the fall. The roots are thick and fleshy.

The doubly or triply compound leaves are the largest of any temperate tree in the continental United States, often about a meter (three feet) long and 60 cm (two feet) wide, with leaflets about 5–8 cm (2.0–3.1 in) long. The petioles are prickly, with swollen bases. In the autumn the leaves turn to a peculiar bronze red touched with yellow which makes the tree conspicuous and attractive.[1]

The habit of growth and general appearance of Aralia spinosa and related tree-forming Aralia species are unique. It is usually found as a group of unbranched stems, rising to the height of 3.5–6 m (11–20 ft), which bear upon their summits a crowded cluster of doubly or triply compound leaves, thus giving to each stem a certain tropical palm-like appearance. In the south it is said to reach the height of 15 m (49 ft), still retaining its palm-like aspect. However, further north, the slender, swaying, palm-like appearance is most characteristic of younger plants that have not been damaged by winter storms.[1]

The trunk, showing the bark, leaf scars, and spines.
  • Bark: Light brown, divided into rounded broken ridges. Branchlets one-half to two-thirds of an inch in diameter, armed with stout, straight or curved, scattered prickles and nearly encircled by narrow leaf scars. At first light yellow brown, shining and dotted, later light brown.
  • Wood: Brown with yellow streaks; light, soft, brittle, close-grained.
  • Winter buds: Terminal bud chestnut brown, one-half to three-fourths of an inch long, conical, blunt; axillary buds flattened, triangular, one-fourth of an inch in length.
  • Leaves: Clustered at the end of the branches, compound, bi- and tri-pinnate, three to four feet long, two and a half feet broad. The pinnae are unequally pinnate, having five or six pairs of leaflets and a long stalked terminal leaflet; these leaflets are often themselves pinnate. The last leaflets are ovate, two to three inches long, wedge-shaped or rounded at base, serrate or dentate, acute; midrib and primary veins prominent. They come out of the bud a bronze green, shining, somewhat hairy; when full grown are dark green above, pale beneath; midribs frequently furnished with prickles. Petioles stout, light brown, eighteen to twenty inches in length, clasping, armed with prickles. Stipules acute, one-half inch long.
  • Flowers: July, August. Perfect or polygamomonoecious, cream white, borne in many-flowered umbels arranged in compound panicles, forming a terminal racemose cluster, three to four feet in length which rises, solitary or two or three together, above the spreading leaves. Bracts and bractlets lanceolate, acute, persistent.
  • Calyx: Calyx tube coherent with the ovary, minutely five-toothed.
  • Corolla: Petals five, white, inserted on margin of the disk, acute, slightly inflexed at the apex, imbricate in bud.
  • Stamens: Five, inserted on margin of the disk, alternate with the petals; filaments thread-like; anthers oblong, attached on the back, introrse, two-celled; cells opening longitudinally.
  • Pistil: Ovary inferior, five-celled; styles five, connivent; stigmas capitate.
  • Fruit: Berry-like drupe, globular, black, one-fourth of an inch long, five-angled, crowned with the blackened styles. Flesh thin, dark.[1]

Distribution and habitat

Aralia spinosa is widespread in the eastern United States, ranging from New York to Florida along the Atlantic coast, and westward to Ohio, Illinois, and Texas. It prefers a deep moist soil.[1] The plants typically grow in the forest understory or at the edges of forests, often forming clonal thickets by sprouting from the roots.

This tree was admired by the Iroquois because of its usefulness, and for its rarity. The Iroquois would take the saplings of the tree and plant them near their villages and on islands, so that animals wouldn't eat the valuable fruit. The fruit was used in many of the natives' foods. The women would take the flowers and put them in their hair because of the lemony smell. The flowers could also be traded for money.

In the past, botanists attributed occurrences of Aralia north of Maryland and Delaware in the Middle Atlantic states to introductions of Aralia spinosa from areas to the south. However some of these occurrences are now known to be of Aralia elata (Japanese Angelica-tree), a related Asian species that is invasive in the area. A. spinosa and A. elata are difficult to distinguish in the field, leading to confusion. In at least one locality, in Philadelphia, A. elata is displacing A. spinosa, with as yet unknown impacts on the local ecology.[3]

Uses

The young leaves can be eaten if gathered before the prickles harden. They are then chopped finely and cooked as a potherb.

Aralia spinosa was introduced into cultivation in 1688 and is still grown for its decorative foliage, prickly stems, large showy flower panicles [clusters], and distinctive fall color. These plants are slow growing, tough and durable, do well in urban settings, but bear numerous prickles on their stems, petioles, and leaflets. These plants can be propagated from seeds or root cuttings.[4]

Early American settlers used the plant for its alleged properties of curing toothaches.[5]

In a laboratory study, extracts from the plant, used as a medicine during the American Civil War, showed antimicrobial activity against multidrug-resistant bacteria associated with wound infections.[6]
