In Michigan, the Northern Hardwoods Ecosystem is the most common forest ecosystem type. The main tree in this forest ecosystem is the sugar maple.

    Beech bark disease is a serious disease affecting American beech throughout the Northeast. In some areas, the slow decline of beech due to this disease has led to shifts in tree species dominance in favor of competing tree species, but in other areas, beech reproduces well and small beech stems dominate.

Reduction of nectria canker in hardwood forests of the northeast / Related Titles. Series: Occasional paper (Northeastern Forest Experiment Station (Radnor, Pa.)) ; no. Grant, Theodore J. Northeastern Forest Experiment Station (Radnor, Pa.) Type. Book. Introduction. Nectria canker is one of the most serious diseases to afflict hardwood trees.

The disease is caused by several species of a is a genus of Ascomycete most widespread and damaging Nectria fungus is Nectria a magnoliae, Nectria coccinea, and Nectria coccinea var.

faginata occur less frequently, but can be just as problematic. Worldwide, Nectria fungi cause several common canker and dieback diseases, especially in hardwood trees.

Nectria canker, which is caused by the fungus, Nectria galligena, may occur on over 60 species of trees and shrubs including apple, ash, birch, dogwood, elm, sweet gum, holly, maple, pear and walnut.A similar disease infects members of the magnolia family. A canker then forms on the trunk and as it matures, it causes the bark to split open.

The tree tries to seal off this wound by producing a ridge of callus tissue around the scar. The infection, rarely lethal, lasts a number of years, and a state of equilibrium is established.

The Northeastern coastal forests are a temperate broadleaf and mixed forests ecoregion of the northeast and middle Atlantic region of the United ecoregion covers an area of 34, sq miles (89, km²) encompassing the Piedmont and coastal plain of seven states, extending from coastal southwestern Maine, southeastern New Hampshire, eastern Massachusetts, and Rhode Island, southward Biome: Temperate broadleaf and mixed forests.

See: Apple (Malus spp.)-Nectria Twig Blight (Coral Spot) Cause Nectria cinnabarina (asexual: Tubercularia vulgaris) and Neonectria ditissima (asexual: N. galligena), fungi that invade trees through wounds and injuries including winter injury, drought damage, sunscald, leaf scars, cracks in the twig axil, or senescent low are splash dispersed from fruiting bodies that exude.

Nectria canker is the most common canker disease of hardwood trees. It seriously reduces the quantity and quality of forest products. This disease usually does not kill trees, but causes serious volume losses. It is common on yellow birch, black walnut, and sassafras.

It also occurs on aspen, red oak, maple, beech, poplar, and birch. University of Illinois Plant Director, Suzanne Bissonnette, examines/diagnoses a sample of Nectria off a beech tree. Encompassing part or all of 28 eastern U.S. states & two Canadian provinces, the Central Hardwood Forests cover a variety of habitats & include trees adapted to a broad range of conditions.

Importance. -- Nectria cankers, caused by N. galligena, are frequently found on some oak cankers are most important in trees less than 20 years old.

The canker can girdle and kill young trees or make them weak and subject to wind breakage. Most regeneration of hardwood forests occurs naturally--that is, without planting trees--but many factors can affect forest regeneration. To regenerate naturally, the current forest must produce seedlings, stump sprouts, and root suckers that will become the next forest following a harvest or natural disturbance.

A Summary of North American Hardwood Tree Diseases with Bleeding Canker Symptoms A.H. Nelson and G.W. Hudler Abstract. Although the presence of bleeding cankers on deciduous trees may raise fears of the presence of Phytophthora ramorum, the cause of sudden oak death, other pathogens also cause similar review of hardwood tree.
