A fast-and-frugal tree is a classification or a decision tree that has m+1 exits, with one exit for each of the first m −1 cues and two exits for the last cue. Mathematically, fast-and-frugal trees can be viewed as lexicographic heuristics or as linear classification models with non-compensatory weights and a threshold.

[ 3 ] [ 2 ] It allows for natural regeneration from site-adapted trees that are retained because of their good genetics.

Windbreaks are sufficiently dense rows of trees at the windward exposure of an agricultural field subject to wind erosion. [7] Evergreen species provide year-round protection; however, as long as foliage is present in the seasons of bare soil surfaces, the effect of deciduous trees may be adequate.
