Tree stands or deer stands are open or enclosed platforms used by hunters. The platforms are secured to trees in order to elevate the hunter and give them a better vantage point. A tripod stand is a similar device, but because it is freestanding rather than attached to a tree, it is not technically a tree stand.
A forest stand is commonly described as in 10ths or 10%s. Thus a ratio could be given of: 3 Ponderosa pines, 2 mangrove trees, 5 silver spruces. If there was a mixed stand that stand mix could be described as mixed up to 10%, mixed 10–40% and a mixed stand over that amount. [citation needed] The form of mixing of the tree types is commonly ...
A young stand of even-aged fir trees growing in a formerly clearcut area in the Sierra Nevada mountains, with an older cohort behind them. Even-aged timber management is a group of forest management practices employed to achieve a nearly coeval cohort group of forest trees . [ 1 ]
The success of practising a shelterwood system is closely related to: 1. the length of the regeneration period, i.e. the time from the shelterwood cutting to the date when a new generation of trees has been established; 2.the quality of the new tree stand with respect to stand density and growth; and 3.the value increment of the shelter trees.
The mixed age of the forest is an important criterion in ensuring that the forest is a relatively stable ecosystem in the long term. A climax stand that is uniformly aged becomes senescent and degrades within a relatively short time to result in a new cycle of forest succession. Thus, uniformly aged stands are less stable ecosystems.
DBH is used in estimating the amount of timber volume in a single tree or stand of trees utilising the allometric correlation between stem diameter, tree height and timber volume. [8] It can also be used in the estimation of the age of veteran trees, given that diameter increment is the only "constant non-reversible feature of tree growth". [9]

Stand density management diagram – model that uses current stand density to project future stand composition; Volume can be calculated from the metrics recorded in a plot sample. For example, if a tree was measured to be 20m tall and with a DBH of 19 cm using previous measured tree data a volume could be approximated according to species.
