Five advantage of exotic trees over local trees
Answers
Answer:
a. Exotic species are used as an alternative in many places where local indigenous forests cannot produce the type, quantity and quality of forest products required.
b. In general, exotic species have growing rates much greater than native species; therefore, they produce more wood per unit of area and time. In the tropics, exotic species could grow 5 to 10 times more wood than native species.
c.Many of the exotic species used in forestry plantations can grow in sites with limited edaphological conditions (as pH, nutrient availability, moist content, texture, etc) with better yield than indigenous species.
d.Exotic species usually can adapt to different environmental conditions; nevertheless, is important to test the exotics in the zone where it is needed prior deciding a large scale plantation establishment.
e.With features as fast growing and wider adaptation, exotic species could be used as source of different type of products and so reduce the pressure over native species (which in general growth less and slower).
