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.
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.
i-Tree is a collection of urban and rural forestry analysis and benefits assessment tools. It was designed and developed by the United States Forest Service to quantify and value ecosystem services provided by trees including pollution removal, carbon sequestration, avoided carbon emissions, avoided stormwater runoff, and more. i-Tree provides baseline data so that the growth of trees can be ...
Morus celtidifolia, the Texas mulberry, is a plant species native to South America, Central America, Mexico, and the southwestern United States, ranging from Argentina north as far as Arizona and Oklahoma. In the US, it grows in canyons and on slopes, usually near streams, from 200–2,200 metres (660–7,220 feet) in elevation.
The leaves are alternate, 7–18 cm (2 + 3 ⁄ 4 –7 in) long (rarely to 36 cm or 14 + 1 ⁄ 4 in) and 8–12 cm (3 + 1 ⁄ 4 – 4 + 3 ⁄ 4 in) broad (about twice as big as the white mulberry's leaves), [3] simple, broadly cordate, with a shallow notch at the base, typically unlobed on mature trees although often with 2–3 lobes ...
Mulberry tree scion wood can easily be grafted onto other mulberry trees during the winter, when the tree is dormant. One common scenario is converting a problematic male mulberry tree to an allergy-free female tree, by grafting all-female mulberry tree scions to a male mulberry that has been pruned back to the trunk.

Site index is a term used in forestry to describe the potential for forest trees to grow at a particular location or "site". Site is defined as "The average age of dominate and/or codominate trees of an even-aged, undisturbed site of intolerant trees at a base age"; [1] furthermore, the word site is used in forestry to refer to a distinct area where trees are found.

Mulberry can be grown up to 4,000 m (13,000 ft) above sea level. Mulberry blooms well in warm, rich, fertile, well-drained, loamy to clayey soils, porous with strong moisture-holding ability. The optimal soil pH range is 6.2–6.8. Because mulberry is a hardy crop, the soil moisture can be used to a greater extent by these plants.
