In biology, the BBCH-scale for olive describes the phenological development of olive trees using the BBCH-scale. [ 1 ] The phenological growth stages and BBCH-identification keys of olive trees are:
An olive tree in Mouriscas, Abrantes, Portugal, (Oliveira do Mouchão) is one of the oldest known olive trees still alive to this day, with an estimated age of 3,350 years, [78] [79] planted approximately at the beginning of the Atlantic Bronze Age. An olive tree in the city of Bar in Montenegro has an estimated age of between 2,014 and 2,480 ...
Although no single tree in this stand is of that age, the stand itself as a single organism has existed that long. [119] Individual trees in the clonal patch have been listed as having ages of 2000 [120] [121] or even to 3000 years old. [122] [123] The olive tree also can live for centuries.
Tree height is the vertical distance between the base of the tree and the highest sprig at the top of the tree. The base of the tree is measured for both height and girth as being the elevation at which the pith of the tree intersects the ground surface beneath, or "where the acorn sprouted."
American Forests, for example, uses a formula to calculate Big Tree Points as part of their Big Tree Program [3] that awards a tree 1 point for each foot of height, 1 point for each inch (2.54 cm) of girth, and ¼ point for each foot of crown spread. The tree whose point total is the highest for that species is crowned as the champion in their ...
Elaeagnus angustifolia, commonly called Russian olive, [2] silver berry, [3] oleaster, [3] or wild olive, [3] is a species of Elaeagnus, native to Asia and limited areas of eastern Europe. It is widely established in North America as an introduced species .
However, as the tree is heavily buttressed, and irregular in shape, a calculation of nominal diameter, defined as the cross-sectional wood area expressed as a circle, gives this tree a diameter at breast height of 30.8 feet (9.4 m)—a much smaller number, but a more accurate representation of the tree's size.

It is mainly used for oil. It is the main variety of olive used to make olive oil in Algeria. [14] Domat: Turkey a common Turkish green olive, a table olive and grown for oil [4] [15] Dritta: Italy a variety of olive tree typical of the DOP area known as Aprutino Pescarese in the province of Pescara (Abruzzo).
