coverSmooth blackberry's extensive colonies provide excellent cover for
wildlife. The colonies create nearly impenetrable thickets where birds,
rabbits, and other animals hide. Colonies of smooth blackberry
are common nesting sites for small birds [

fruit,
shrubSmooth blackberry is a deciduous, erect or arching, thicket-forming
shrub which grows to 10 feet (2-3 m) in height [
3,
32,
35,
36]. The
alternate compound leaves are 4 to 8 inches (10-20 cm) long. The
numerous flowers are borne in clusters of up to 25. The fruit is an
aggregate of small drupes, each containing a single hard-pitted nutlet
[
3,
32]. Rhizomes are typically about 3 to 4 inches (8-10 cm) below the
surface [

Fire Ecology
(
الإنجليزية
)
المقدمة من Fire Effects Information System Plants
Smooth blackberry is favored by fire [
29,
35,
38]. Burning typically
stimulates sprouting [
5]. Root crowns and rhizomes are primarily in the
mineral soil, a morphological trait that favors high rates of survival
following fire [
9]. Even severe fires provide conditions where
smooth blackberry can establish or increase [
29,
37].
Spruce-fir forests, in which smooth blackberry occurs, burn
infrequently but are more likely to burn after logging or other
disturbances [
37].

More info for the term:
shrubsMaintaining openings in the overstory is the key to promoting smooth
blackberry because invading trees and shrubs quickly shade it out.
Smooth blackberry can be encouraged or rejuvenated by removing
overhead shade, mowing, light burning, or deep cultivation [

Smooth blackberry is moderately sensitive to ozone [

Smooth blackberry reproduces from seeds, by sprouting from rhizomes

increase in smooth blackberry [

المقدمة من wikipedia EN
Rubus canadensis is a North American species of flowering plant in the rose family known by the common names smooth blackberry,[2] Canadian blackberry, thornless blackberry and smooth highbush blackberry.[3] It is native to central and eastern Canada (from Newfoundland to Ontario) and the eastern United States (New England, the Great Lakes region, and the Appalachian Mountains).[4][5]
This rhizomatous shrub forms thickets up to 2 to 3 meters (7–10 feet) tall. The leaves are deciduous and alternately arranged, each measuring 10 to 20 centimeters (4-8 inches) long. The inflorescence is a cluster of up to 25 flowers. The fruit is an aggregate of many small drupes, each of which contains a tiny nutlet. The plant reproduces by seed, by sprouting up from the rhizome, and by layering. The stems can grow one meter (40 inches) in height in under two months.[4][3]
Rubus canadensis grows in many types of forested habitat, as well as on disturbed sites. Associated plants may include mountain maple (Acer spicatum), serviceberry (Amelanchier spp.), hobblebush (Viburnum alnifolium), scarlet elder (Sambucus pubens), common blackberry (Rubus allegheniensis), beaked hazel (Corylus cornuta), southern mountain cranberry (Vaccinium erythrocarpum), minnie-bush (Menziesia pilosa), and rosebay (Rhododendron catawbiense).[4]
Many types of animals feed on the fruits and foliage of this shrub. The thickets provide cover and nesting sites.[4]
The fruits of this plant provided food for Native American groups, who also used parts of the plant medicinally at times.[6]

Rubus canadensis est une espèce de plantes de la famille des rosacées et du genre Rubus. Elle est native des forêts d'Amérique du Nord. Les Lenapes utilisaient le fruit et d'autres parties de la plante contre la dysenterie[1].
Description
Rubus canadensis peut atteindre 2,5 mètres de haut. Ses turions, de couleur brun jaunâtre, sont glabres et dépourvu d'épines. Ils comportent des feuilles digitées à cinq folioles pouvant être légèrement imbriquées. Le foliole terminal est vert jaunâtre, fin, plissé, et possède un limbe régulièrement denté. Les fleurs, d'un diamètre de vingt millimètres, sont blanches. L'inflorescence est un racème composé de 6 à 8 fleurs. Les sépales sont pointues et de couleur vert marginée de blanc. La floraison a lieu en juin. Les fruits sont longuement cylindriques.

المقدمة من wikipedia VI
Rubus canadensis, được biết đến với nhiều tên gọi phổ biến như mâm xôi mịn, mâm xôi không gai, mâm xôi mịn bụi cao hay mâm xôi Canada, là một loài thực vật có hoa thuộc chi Mâm xôi. Đây là loài bản địa của hai quốc gia Canada, chủ yếu là miền trung và miền đông của nước này (từ Newfoundland đến Ontario), và Hoa Kỳ, chủ yếu là phía đông (New England, khu vực xung quanh Ngũ Đại Hồ và dãy Appalachia)[1][2].
Mô tả
R. canadensis là cây bụi thân rễ, cao khoảng 2 - 3 mét; khoảng 2 tháng thì nó đã cao tới 1 mét. Thân của nó gần như không có gai nhọn nên được gọi là "mâm xôi mịn (hoặc mướt)", rất mảnh và dày khoảng 2 – 5 mm. Lá rụng theo mùa và mọc xen kẽ nhau, có hình elip, rất mịn, lông thưa thớt ở mặt dưới, có răng cưa, dài khoảng 10 – 20 cm và rộng khoảng gần 10 cm. Hoa mọc thành cụm 15 đến 25 hoa, cuống không có lông; hoa lưỡng tính, màu trắng, đường kính khoảng 8 – 22 mm; nở vào tháng 5 đến tháng 7. Quả hạch dài tới 25 mm, màu đen, tím và đỏ, vị ngọt, rất được ưa thích trong số các loại quả mâm xôi khác. Cây có thể mọc từ hạt giống hoặc từ thân rễ mẹ[3][4][5][6].
R. canadensis rất ưa đất nhiều mùn và những nơi có nhiều nắng (hoặc bóng râm), cây con mọc vào mùa thu, lá rụng vào mùa đông nhưng vẫn còn trên cành. R. canadensis thường sinh trưởng trong các bụi râm, rừng thưa hay các trảng cỏ[4][5].
R. canadensis có hình thái tương tự như Rubus allegheniensis ngoại trừ nó không có lông tơ[3].
Sử dụng
Quả có vị khá ngọt, có thể ăn sống, sấy khô hoặc nấu chín, làm mứt hoặc thêm vào bánh nướng. Nước sắc của thân và gốc đã được sử dụng để điều trị bệnh lỵ. Thuốc nhuộm màu xanh lam hoặc màu dương đậm có thể thu được từ quả[5].
Đây là nguồn thực phẩm quan trọng của người Mỹ bản địa và những động vật khác. Các bụi cây cũng là nơi trú ngụ của các loài chim, sóc[6].
