Acer rubrum, the red maple, also known as swamp maple, water maple, or soft maple, is one of the most common and widespread deciduous trees of eastern and central North America. The U.S. Forest Service recognizes it as the most abundant native tree in eastern North America. [ 4 ]
The striped maple is a small deciduous tree growing to 5–10 meters (16–33 ft) tall, with a trunk up to 20 cm (8 in) in diameter. [3] The shape of the tree is broadly columnar, with a short, forked trunk that divides into arching branches which create an uneven, flat-topped crown.
The mean annual increment (MAI) or mean annual growth refers to the average growth per year a tree or stand of trees has exhibited/experienced up to a specified age. For example, a 20-year-old tree that has a stem volume of 0.2 m 3 has an MAI of 0.01 m 3 /year.
Acer grandidentatum, commonly called bigtooth maple or western sugar maple, [2] [3] is a species of maple native to interior western North America. It occurs in scattered populations from western Montana to central Texas in the United States and south to Coahuila in northern Mexico .
Where: Y is the yield (volume, height, DBH, etc.) at times 1 and 2 and T 1 represents the year starting the growth period, and T 2 is the end year. Example: Say that the growth period is from age 5 to age 10, and the yield (height of the tree), is 14 feet at the beginning of the period and 34 feet at the end.
Slowdown in radial growth rates can occur without slowdown in corresponding cross-sectional area or volume growth. For example, research by Leverett [ 24 ] has shown that even older white pine trees continue to add significant wood volumes, with 11 monitored trees on average adding 11.9 cubic feet (0.34 m 3 ) annually.
Acer macrophyllum, the bigleaf maple [2] or Oregon maple, [3] is a large deciduous tree in the genus Acer. It is native to western North America . In addition to uses by animals, it is of some culinary and woodworking interest.
When stocking, a tree's basal area is measured. The basal area is a cross-sectional area of the stump taken about 4.5 feet (1.4 m) above the ground. [7] The equation for calculating the basal area of trees in a stand is Basal Area = 0.005454 DBH 2, where DBH is the diameter of the tree at the aforementioned measuring height. [7]
