roundish. oklahomensis and subsp.
Michigan Natural Features Inventory, Lansing, MI. While northern shrub thicket has replaced many declining and rare communities, it does provide important ecosystem services, protecting water quality by assimilating nutrients, trapping sediment, and retaining stormwater and floodwater. Floristic diversity is usually correlated with the degree of shrub canopy closure, with higher levels of diversity occurring in more open sites.

They do love areas with moist or wet soil with good drainage if available. Winter Key. 906-786-1575. Running strips perpendicular to a stream will let woodcock find earthworm prey by shifting uphill or downhill, depending on the soil moisture content. This species is a recipient of the Award of Garden Merit from the Royal Horticultural Society. The 3-4 inch LEAVES are single-toothed with heart-shaped It commonly grows in wet soils and develops the multiple-stemmed growth form as shown above. For information about plant species, visit the Michigan Flora website. Plants with nitrogen fixation capabilities form symbiotic relationships with bacteria that allow them to capture that element. 1987. It is the namesake of a type of wetland known as "alder thicket".
It is most often seen in a multi-trunked form with a densely branched crown. It also has good sound properties and is easy to finish with stains. The two most common species used to make their guitars are the black alder (Alnus glutinosa) and the red alder (Alnus rubra). NC State University and N.C. A&T State University work in tandem, along with federal, state and local governments, to Trunks feature smooth gray bark with inconspicuous lenticels (pores). Cohen, J.G., M.A. The species name rhombifolia indicates that the leaves are shaped like a rhombus. There are three different subspecies of the seaside alder: subsp. (Alnus crispa) Tag Alder, Green Alder, and American Michigan Natural Features Inventory, Michigan State University Extension, Lansing, Michigan. If the roots are established, they can tolerate a little drought. Beaked hazel houses the NUTS in bristly husks with a tube-like Powdery mildew and leaf curl may also appear. Alder trees and shrubs (Alnus spp.) This genus is able to fixate nitrogen. the Deciduous Summer Key or the Deciduous
However, northern shrub thickets have replaced many rare and declining wetland communities such as rich conifer swamp and northern fen.
Michigan Natural Features Inventory, About the Natural Community Classification. Female catkins develop into 1-inch long fruiting cones (strobiles) to 3/4” long containing winged nutlets (seeds). Insects, Diseases, or Other Plant Problems: Canker can be severe on the Tag alder.
Vanessa Richins Myers is a seasoned horticulturist, garden writer and educator with 10+ years of experience in the horticulture and gardening space. Most are shrubs.
The FEMALE CONES are woody and about a half-inch
Fruiting cones mature to dark brown in fall, with persistence into winter. Knighton, and R. McRoberts. Global Rank: G4 - Apparently secure No serious insect or disease problems. Insignificant fall color.
These trees and shrubs can be an integral part of a butterfly garden since there are many different species that use the leaves as larval food. kolaensis, subsp. Superior. Michigan Natural Features Inventory, Report No. brown to purplish and shiny. Northern shrub thicket has also been maintained and expanded by wildlife management geared toward providing favorable habitat for game species of early-successional habitat, particularly white-tailed deer, American woodcock, and ruffed grouse. The fruit attracts butterfly larvae, mammals, and birds which feed on the seeds.

The MALE catkins
In late winter, slim, green, male flowers and red, female flowers mature. Hazel brush can grow to 15 feet tall, but usually is 4-6 feet in height. The whole fruit is
georgiensis, subsp. It is also found in or adjacent to sedge meadows, shrub carr and swamps, along streams and in roadside ditches. Characteristic ferns and fern allies include common horsetail (Equisetum arvense), sensitive fern (Onoclea sensibilis), cinnamon fern (Osmunda cinnamomea), royal fern (O. regalis), and marsh fern (Thelypteris palustris).
MSU is an affirmative-action, equal-opportunity employer.
Most are shrubs.
Broad elliptic to obovate dull green leaves (2-4" long) with serrulate margins are wedge-shaped at the base and pointed at the tip. The small tree produces a seed that matures in the fall and persists through the winter.
Northern shrub thicket is a shrub-dominated wetland located north of the climatic tension zone, typically occurring along streams, but also adjacent to lakes and beaver floodings.
Alder can be regenerated by manual cutting with a chainsaw. There are several different subspecies found throughout the world. Female flowers are pollinated by wind.
growing in richer swamp settings. For a full list of references used to create this description, please refer to the natural community abstract for Northern Shrub Thicket. rugosa (Du Rois) Clausen. One option is to cut a series of long strips along stream corridors, chewing down around 25 percent of the alder in the stand every five years. The Harvester butterfly does not sip flower nectar but they do feed on aphid honeydew. Prolonged periods without fire, an absence of beaver flooding, or the lowering of the water table allows for shrub encroachment into open wetlands and conversion to northern shrub thicket. TAG Tolerates poor soils. The community typically grades into northern wet meadow along stream and lake margins, and along the margins of uplands it often borders swamp forest. The bark is smooth and gray-brown with a fluted appearance.
It can be found naturally in wet areas including streambanks and bogs. Often, though, wetlands shrubs become overmature. These types of management patterns yield and perpetuate a combination of thick young shrubs as well as some older shrubs. The buds and seeds of alder are eaten by a diversity of birds.
The species name cordata tips you off that this has cordate—or heart-shaped—leaves. Kost, B.S. Click HERE to return to the home page. The Garden wouldn't be the Garden without our Members, Donors and Volunteers.
They are somewhat similar in appearance to the cones found on conifers.
there are several shrub-sized species. maintained by Bill Cook, MSU Extension Forester for the Upper Peninsula of Michigan. Robert H. Mohlenbrock / USDA-NRCS PLANTS Database. 8 pp. Enander, and K.M.
They present as catkins, with the males being longer than the females. In the U.P. An alder stand is usually too old to provide high-quality habitat when the shrubs’ limbs become thick and grow horizontally instead of vertically.
Shrub wetlands occur in the floodplains of rivers and streams (biologists refer to those areas as “riparian zones”) and in bogs, marshes, swamps, and swales.
Following canopy release, alder can form dense, impenetrable thickets that retard or prevent tree establishment. Huenneke, L.F., and P.L.
Male catkins (brownish-yellow flowers) are slender, cylindrical and droop in clusters of 2-5 from near the branch tips to 2-4" long. Learn tips for creating your most beautiful (and bountiful) garden ever.
This species of alder has been used in many ways over the year.
Ohmann, L.F., M.D. Learn more about managing old farmland to help wildlife in Best Management Practices for Woodcock and Associated Bird Species. In late winter, slim, green, male flowers and red, female flowers mature.
Two good places to see active alder management are Lake Tomahawk Demonstration Area in Oneida County and Ackley Demonstration Area in Langlade and Marathon Counties.
2007-21, Lansing, MI.
The Spruce uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles.
2020. When cutting in shrub wetlands, remember to keep a few trees to provide singing perches for golden-wings and other songbirds. Meandering cutting patterns that follow the topography while keeping shrub patches throughout an area will attract songbirds such as the golden-winged warbler. Almost all of them are deciduous. The leaves are alternate with a wavy, toothed margin and hairy underside. TREE IDENTIFICATION KEY They are Alnus viridis subsp. Roth. A host of songbirds from alder flycatchers to golden-winged warblers breed in shrub wetlands.
The soils are characterized by high nutrient levels due to the nitrogen-fixing ability of alder.
