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 ...
As far as plants and vegetation are concerned, the accumulation of salts in the soil adversely affects their physiology and morphology by increasing the osmotic pressure of the soil solution, altering the plant’s mineral nutrition, and accumulating specific ions to toxic concentrations in the plants.
Synthetic polymers began replacing other chemical binders for soil stabilization in agriculture in the late 20th century. [1] Compared to traditional chemical binders, polymer soil additives can achieve the same amount of strengthening at much lower concentrations – for example, mixtures of 0.5-1% of various biopolymers have strength levels that match or exceed those of 10% cement mixtures ...
As plants mature, gravitropism continues to guide growth and development along with phototropism. While amyloplasts continue to guide plants in the right direction, plant organs and function rely on phototropic responses to ensure that the leaves are receiving enough light to perform basic functions such as photosynthesis.
Hydraulic redistribution is a passive mechanism where water is transported from moist to dry soils via subterranean networks. [1] It occurs in vascular plants that commonly have roots in both wet and dry soils, especially plants with both taproots that grow vertically down to the water table, and lateral roots that sit close to the surface.

The vertical stratification of a community is determined largely by the life forms of plants their size , branching and leaves which is influenced by the vertical gradient of light. Vertical classification of vegetation in a forest showing the tree, shrub and herb layers and the forest floor.
Green wall at the Simon Fraser University, Burnaby, British Columbia, Canada.. A green wall is a vertical built structure intentionally covered by vegetation. [1] Green walls include a vertically applied growth medium such as soil, substitute substrate, or hydroculture felt; as well as an integrated hydration and fertigation delivery system.
