Causes of extinction of Black buck

PRACTICAL “Causes of extinction of species”:

Extinction of species is defined as ‘When all the members of a same species become extinct or decline from the earth is called the extinction of this species’

According to IUCN Extinction of species is defined as ‘No individual has been observed from 50 years of a species’

When we talk about the causes of extinction of species then we consider the following points given below

Ø  Habitat loss

Ø  Limitations of resources

Ø  Hunting

Ø  Introduction of exotic species

Ø  Natural disaster

Ø  Human impact

Ø  Predation

Ø  Environmental changes or Climatic changes

Ø  Diseases

Ø  Competition

a)      Inter specific

b)      Intra specific

These are the major causes of extinction of species because every ecosystem is depend upon the food chain and food web, any kind of change in chain cause going to unsustainability of ecosystem. Conservation is essential to protect our biodiversity.

Visit to biodiversity park of Drawer Fort:

When we visit to Biodiversity Park of drawer fort to find the number of species which become extinct up to that time then we observe that or come to know that Black buck is the major species in this park which is fully extincted. Then now the major point is to explain the causes of extinction of Black buck in this park. After visit we observe the fallowing causes of extinction of this species so

Causes of extinction of Black buck:

1)      Habitat loss

2)      Hunting

3)      Diseases

4)      Rainfall

5)      Human Impact

6)      Harsh Climate

1)    Habitat Loss

Habitat loss is one of the important factor taking part in extinction of species. When we study the extinction of black buck species in Cholistan then the main question arising in our mind are:

i) How habitat destruction takes place

ii) Effect of Habitat loss on Black buck species

iii) Restoration of Habitat will cause extinction or not?

How Habitat destruction occur:

Habitat is the space or place where an individual live. So Destruction of habitat loss will be the disturbance in place where living organism live i.e Disturbance in Black buck Habitat. Human impact is the main cause of Habitat destruction and harsh climate due to low rainfall in this desert area.

Effect of Habitat loss on Black buck species

As we know that habitat is the place where an individual live so habitat loss will cause the Extinction of black buck species. Thus extinction is the effect of habitat loss on the black buck species. 

Restoration of Habitat will cause extinction or not?

The question here is that reforestation of habitat will cause extinction or not? The answer of this question lie in the fact that both reforestation and deforestation cause change in the biodiversity and this harmful change  is the respond to imbalance in ecosystem and leads to the extinction of aerated species e.g Black buck extinction in Dirawar Fort.

2)    Hunting :

Hunting is the illegal killing of organisms for the purpose of food and money. So it is also a factor that also take part in the extinction of Black buck species. Peoples of this area are not too much civilized so they don’t know the hunting may leads to the extinction of this species forever. They hunt black buck and now this species become extinct in Desert area of Dirawar fort. 

3)    Diseases :

Diseases are some sort of abnormalities in living organisms which may lead to the death of this organisms so after observing the field of this desert we can say that diseases are also factors cause the extinction of Black buck  

4)    Rainfall :

Rainfall is also a important factor because it is responsible for humidity of air, temperature of air or environment, (pressure which take part in flow of air) and plant diversity of environment because water is essential for existence of every type of life. So including all these things which are interconnected to each other relatively cause the extinction of black buck in the biodiversity of Dirawar fort. Here there are two possibilities

Ø  Lowest rainfall in the history of desert of Dirawar fort is 

Ø  Highest rainfall in the history of desert of Dirawar fort is

Average rainfall : 12 cm (5 inch) per year

5)    Human impact :

Due to lack awareness to the importance of biodiversity humans living over there perform hunting and kill many of animals for the source of food. This activity of humans affect the living species i.e Black buck. Humans also cause deforestation which cause desertification as well as extinction.

6)    Harsh Climate :

Harsh climate includes the low rainfall and very high temperature of the desert environment which is also a main factor of extinction of black buck species in the biodiversity of Dirawar fort desert.
