Increased crown dieback symptoms in the trees prompted the investigation. Sugar maple (Acer saccharum) trees in the northern Great Lakes region have recently been reported as having increased crown dieback symptoms, prompting further investigation across the region. Upon evaluation of the dieback over a period of 3 years across a plot network, researchers at the Michigan Technological. Plant Health Care Recommendations for Sugar Maple Sugar maple (Acer saccharum) is a large growing, highly desirable shade tree for many northern landscapes. During the summer it has medium green leaves which change to brilliant yellow, orange and red in the fall. Sugar maple will grow to a height of 60 to 80 feet in theFile Size: KB.

  More recent research is less reassuring. Sugar Maple declines reportedly are continuing in our area. For instance, a analysis of growth rings from hundreds of trees across the Adirondack Mountains revealed a decline in the growth rate for a majority of Sugar Maple trees after The causes of this decline are unclear. there is no current management experience (Parker, ). Sugar maple (Acer saccharum) biogeography has been studied using GIS, modelling and pollen records on a broad scale. The major conclusions of these studies have been that the species may decline in the southern portion of its range and migrate northward in the future (Lamhonwah, ).

Studies in an year-old sugar maple, Acersaccharum Marsh., stand indicated that since the early stages of stand development, sugar maples that are currently declining showed slower growth than healthy trees.

A steady growth decline of all dominant trees during the last 30 years was significantly correlated with adverse climatic by: Radial growth in the sugar maple stands generally has shown a reduced rate of growth for the past three decades, with declining trees showing a much greater loss of growth than healthy trees.

Further, tapped trees on the same woodlot have displayed poorer growth than untapped by: Sugar maple (Acer saccharum Marsh.), a keystone species of northern hardwood forests, is susceptible to decline, especially on sites low in the soil base cations calcium (Ca) and magnesium.

THE DECLINE OF SUGAR MAPLES (ACER SACCHARUM). Sugar maples across the northeastern US and eastern Canada are in decline. The problem is not new, but the incidence and severity of maple decline have increased markedly in recent decades to include urban, sugar-bush, and forest environments (Horsley et al., ).Symptoms include reduced foliage and reduced twig growth, and.

Wood cores were taken at breast height of mature sugar maple (Acer Saccharum Marsh.) trees of approximately the same age from four sites in Ontario, Canada differing in soil characteristics and general tree health.

The soils of two of the sites were acidic (podzols), while the soils of the other two sites were calcareous (brunisols). Selected elemental analyses using Neutron Cited by: veys for sugar maple decline assessment.

A maple decline index model incorporating video image spectral and textural characteristics was developed with the aid of aerial photographic interpretation. The model was then compared to a ground-based model currently utilized by the Ontario Ministry of Environment (OME).

THE DECLINE OF SUGAR MAPLES (ACER SACCHARUM) Sugar maples across the northeastern US and eastern Canada are in decline. The problem is not new, but the incidence and severity of maple decline have increased markedly in recent decades to include urban, sugar-bush, and forest environments (Horsley et al., ).

We used tree-ring chronologies from sugar maple (Acersaccharum Marsh.) stands showing various degrees of dieback (i.e., 16 sugar maple chronologies from healthy trees and 11 from damaged trees), distributed throughout the species range in southern Quebec, to analyze the spatial extent and timing of the recent sugar maple rmore, six tree-ring chronologies of American beech Cited by: Maple decline affects primarily sugar maple, Norway maple, and red maple in the Northeast and Midwest.

The problem is not a new one; stagheaded maples were described as early as in Massachusetts. At that time, dieback was attributed mainly to drought and poor conditions for tree growth afforded by the urban environment.

Sugar Maple. Aceraceae -- Maple family. Richard M. Godman, Harry W. Yawney, and Carl H. Tubbs. Sugar maple (Acer saccharum), sometimes called hard maple or rock maple, is one of the largest and more important of the grows on approximately million hectares (31 million acres) or 9 percent of the hardwood land and has a net volume of about.

Maple Tree Types. Maples are deciduous trees characterized by opposite leaf arrangement and spectacular fall color. The flowers are upright and green, yellow, or red in color depending on species, and the fruit appears in winged clusters which hold the seeds of this self-pollinating tree. The survey was conducted on permanent plots across the range of sugar maple in Ontario.

A number of variables (McLaughlin et al., b) were assessed on these sites to provide information on the health of each stand (Table I).

THE ONTARIO FOREST HEALTH DATA CO-OPERATIVE Figure 3. Norway Maple leaves are very similar to Sugar Maple. Many tree ID beginners get the two trees mixed up. Here they are pictured together for comparison. The Sugar Maple leaf is on the bottom.

Note that the Norway Maple leaf has more points. The quick and easy way to tell them apart is that Norway Maple have milky sap. This is easily seen by. Introduction.

Sugar maple (Acer saccharum Marsh) is arguably the most ecologically and economically important species in the northern hardwood forests of eastern North ically, sugar maple provides nutrient‐rich litter to forest soils (Long et al.Lucash et al.

Swings in temperature are not good for their health. Sugar maples are very demanding for site quality to be of the highest quality, and I have always termed them as the “oyster of the woods.”.Ontario Maple Syrup Regulations (Ontario Maple Syrup Producers Association).

INTRODUCTION Sugar maple was designated as Canada’s national tree in The maple leaf adorns the Canadian Flag. Aboriginal people in North America used the tree’s sap to make maple sugar. The practice was later adopted by European settlers.
