what type of soil is used to grow the ghaf tree?
Answers
One reason for the very much in vogue plantation drive is that in 2008 the ghaf was declared the national tree of the UAE. A drought-tolerant, evergreen tree native to the desert, the ghaf is a resilient plant and good for the soil and requires little water.
Answer:
The Ghaf tree also known as Prosopis cineraria has been an essential part of the UAE’s distinctive desert environment and the civilization that have emerged here in the Emirates. Ghaf tree culturally and traditionally is as valuable and precious as it is ecologically. Groves of ghaf grow naturally in the desert sands and wide wadis in all emirates, but unfortunately they are becoming extinct. In this project we will discuss the causes of extinction of the Ghaf tree, why it is threatened and the impacts that could lead to the extinction of the Ghaf tree.
Forests are fabulous places, were you can see different types of Insects, mammals and birds. They are also places that embrace various flowers, trees and grasses. Actually, this sight maybe a good explanation that illustrates the term “Biodiversity”. Biodiversity is a vague word that has ). many definitions among researchers and scientists. In fact, researchers have different definitions according to their different goals, perspectives and values. Takacs (1996) defined the biodiversity as a “full variety of life on Earth”, while Chadwick (1993) thinks that this word is simply defined as “nature” or “wilderness”. However, the general idea among all the researchers is that the biodiversity is the study of the process that makes and sustains the variation of the species on the earth (redpath-museum, 2010). It illustrates the idea of the relationship between the individual and the population, and the population with the community. Moreover, biodiversity is considered as a part of nature because it plays a big role in affecting animals and plants in both terrestrial and aquatic biomes (Ecosystem, 2008).
Due to researches, there are three main types of biodiversity. The first type is the ecological or ecosystem diversity. An ecosystem is a structure which includes living organisms and non living organisms functioning together to maintain the life cycle (Ecosystem, 2008). The ecological diversity refers to the total of different types of ecosystems with the different species within them. The diversity of species within an ecosystem is affected by the ecosystem itself. That is because each species need a different habitat that it is suitable to live and reproduce within it. The second type is the species diversity. It means the number of plants and animals that exist in an area. Essentially, some regions are richer of species than other regions. For example, the tropical forests have much more species than other regions like the poles. The third type is the genetic diversity. This type explains that each member or individual within a species is different from the other members from the same species (BIODIVERSITY, 2010). The differences are in the genetic structure that gives each member his own characteristics. A clear example for the genetic biodiversity is the human beings. Each person has different characteristics than the others because of the genetic building in each one of them. In fact, the genetic diversity is crucial for the species health and diversity because it keeps the diversity among individuals and therefore protects the species from being extinct.
