Darren should research the causes of wolf population decline within other nature reserves to find the answer to this question.
Hence Option (b) is correct.
Wildlife originally referred to undomesticated animal species, but it has now expanded to include all living things that develop naturally or exist in the wild without human intervention.
Some major reasons that can cause a decline in the population of wolves or any wildlife are :
1) Exploitation: The demand for animals has increased as human populations have increased. So they overexploit the wildlife for selfish reasons.
2) Habitat loss
3) Human Land Use and Wildlife Competition for Space that leads to degradation of the habitat.
4) Invasive species: Invasive species are animals that are not native to the area and which enter the area, quickly breed, and spread.
5) Climate change due to pollution, global warming, and some other factors.
6) Diseases
