Grubbing is performed following clearance of trees to their stumps, preceding construction. [1] In animal behaviour grubbing is a feeding technique, referring to digging and uprooting of roots and rhizomes of plants. It is employed by geese, especially greater and lesser snow geese and Canada geese, [2] as well as swine. [3]
Roads, sidewalks and foundations can all suffer structural issues from tree roots. [7] Several methods of control have been attempted, from barriers to encouraging growth in desirable directs. Selection of plants with root systems that will not conflict with nearby structures is the most effective method of damage control.
Root barriers are also used to separate plant roots from each other. In particular, walnut trees secrete the chemical juglone which is toxic to other plants but the use of root barriers can prevent the yield reduction that would normally occur when walnut trees are alley cropped with maize as often occurs in the American Midwest .
Girdling prevents the tree from sending nutrients from its foliage to its roots, resulting in the death of the tree over time, and it can also prevent flow of nutrients in the other direction depending on how much of the xylem is removed. A branch completely girdled will fail; and, when the main trunk of a tree is girdled, the entire tree will ...
Wind throw is the toppling of a tree due to the force of the wind, this exposes the root plate and adjacent soil beneath the tree and influences slope stability. Wind throw is a factor when considering one tree on a slope; however, it is of lesser importance when considering general slope stability for a body of trees as the wind forces involved represent a smaller percentage of the potential ...
A fallen tree with exposed root plate Uprooting is a form of treefall in which the root plate of a tree is torn from the soil, disrupting and mixing it and leaving a pit-mound . [ 1 ] [ 2 ]
