The species would not thrive, would probably not reproduce, and would then go extinct. It is clear then that the set of features we see on a plant are ones that have been successful in the course of evolution. Thorns on roses are one type of adaptation. Thorns are actually modified leaves. The thorns help protect the plant. Another example of a modification is the shape of rain forest leaves. The drip tips of rain forest leaves have adapted to cope with high levels of rainfall. The tip is shaped in a way that allows raindrops to run off quickly.

Windbreaks or shelterbelts The third category is plants that were intentionally introduced as windbreaks or shelterbelts. Windbreaks consist of a linear arrangement of trees and shrubs. Shelterbelts are multiple rows (four or more) of trees and shrubs. Plants in windbreaks or shelterbelts do exactly what the name implies; they break up strong gusts of wind. The importance of halting the velocity of the wind is that, similar to soil stabilizers, it helps to reduce soil erosion. Stronger gusts are more able to move soil particles.

Another way that allelopathic chemicals can be encouraged to decompose is by tillage. Tillage uses plows or discs to cut up and bury plant parts. Tillage turns soil over and exposes the soil to air that helps break down the chemical compounds in the soil. Farmers use tillage to control weeds and to provide the seedbed for planting crops. The disadvantage of tillage is that exposing the soil to the air can dry it out. In areas where water is relied on mostly through irrigation, tillage is reduced to conserve water.
