Bringing Species Back from the Brink


How do you judge whether a reintroduction project is successful? Develop simple ad the increasingly detailed criteria to evaluate a project’s success.

Reintroduction of the species is the deliberate release of a species into the wild, from captivity locations where animals or organisms continues to exist. The main objective of species reintroduction is to set up a healthy, genetically diverse, self-sustaining populace to a position where it has been extirpated, or to supplement an obtainable population (McNeely, 20). Most of the species that need reintroduction are often whose existence has become susceptible or endangered in the wild. On the other hand, the reintroduction of the species can also for the pest control. For instance, wolves being reintroduced to a wild region due to an overpopulation of elk or deer are an example of the reintroduction procedure. Similarly, reintroduction might involve native species to the locality where they had been extirpated; some people prefer the term “restoration” (Mills, 13).

The reintroduction of species to locations within their former range or in another appropriate location is amenable to species survival. The reintroduction method is entrenched in conservation biology. The criteria used in this case improve the conservation status of focal species or restore ecological unit functions and processes. Just like it is in business, using the project management processes, the reintroduction project can be said tobe successful by considering the timeline and completion of the project against the reintroduction requirements. However, what is not accounted for, and has the potential to disrupt a project at a later stage, are subjective analyses. The evidence of success in this situation is seen on the creased number of species as explained on page 253.

Would it be a good idea to create new wild populations of African rhinoceroses, elephants, and lions in Australia, South America, the southwestern United States or other areas outside their current range as described by Donlan et al. (2006)? What would be some of the legal, economic, and ecological issues involved?

In my view, this action is seen as a global biodiversity connected to its ecosystem services. Due to risk in the species extinctions, I think it is advisable to try and create new wild populations of other species, not only African rhinoceroses outside their current range. Currently, the atmosphere is facing various challenges with global warming being one of them. In this situation, the climatic change in various locations can as well affect the lives of these rhinoceroses and other animals. Therefore, taking them to different places with a favorable environment is a good idea.  To stop the species from getting vanished, reintroducing the extinct species may be a partial solution to the problem. However, the success of such an act will depend on the ecological community and the response of the same community to the species being reintroduced and its extinction.

In the animal field, the black adult black or white rhino, elephants, and lions have no predators apart from human beings. They are killed by hunters for their horns with a significant demand in Asia for making ornaments. Due to increase in human population, bigger towns and cities have emerged as well as increased agricultural activities that taken animals’ space. As much as taking rhinos and elephants to other places might be a good idea, there is one thing that people must know; rhinos are one of the iconic symbols of the African savanna even though its existence is at risk. Due to that risk on them, it is a noble idea to move them to Australia to save their lives. This exercise involves legal, economic and ecological issues. First and foremost, it is important to note that containing poachers especially in Africa has become a challenge; there are no stable and efficient legal mechanisms to get rid of poachers that have continued to kill the animals. Australia is one of the places with tight rules when it comes to protecting wildlife and moving the animals is a great idea. On the other hand, regarding the economic benefit, Africa and different regions that have subscribed to that notion of letting the animals leave their territory are set to lose the revenue that was generated through the parks. As all these are being considered, it is also necessary to look at the environmental conditions; is the Australian atmosphere favorable for the existence of the rhinos? For such a project to be initiated, the stakeholders must have conducted their research to determine whether the animals will survive.

Would biodiversity be adequately protected if every species were raised in captivity? Is this possible? Is it practical? How would freezing a tissue sample of every species help to protect biodiversity? Again, is this possible or practical?

Biodiversity entails the variety of all living organisms such as ecosystem, animals, plants and their habitats as well as genes which are fundamental to life on the planet. In every place on Earth, all living things live together and are involved in complex networks of inter-reliant relationships known as an ecosystem. However, in a situation where some species are raised in captivity, biodiversity would not be adequately protected same as it is when the animals are left to move freely. Freezing tissue sample of endangered species in liquid nitrogen at approximately -196 degree to -373 degrees Celsius are important in conserving the species. These temperatures can safeguard tissue samples for an indefinite period as long as the desired temperatures are maintained all through. The conservation of the samples guarantees the survival of the species meaning that; biodiversity is still protected through the existence of various species. The method appears to be good; however, it might be difficult to implement at some point due to technical challenges. In this case, the source of or power supply to the storage facility where the temperature is being regulated should be constant and must not have any defects; it is practical.
