How best to Reintroduce Animals Into The Wild

There are a great number of benefits and problems with reintroducing animals into the wild. There are lots of factors to bear in mind, such as the animal’s effect on the landscape and whether it could be a threat to humans and animals that now live there.
Also when the animals were not in a certain area, the ecology will have likely stabilised without them so reintroduction will have a significant effect on the ecology and could cause other animals to be negatively impacted.Has it been done effectively before? In 1981 the black-footed ferrets were seen as extinct but were found in Wyoming. Only 18 were left. In 1987, they were taken into captivity to breed together, and luckily they are fast-breeding animals. The reintroduction began in 1991 and there were 29 different sites for this. This was done to reduce the likelihood of a catastrophic event that could have gotten rid of all of them. As a result of this 300 ferrets were living in the wild and each year, 150-220 ferrets are conditioned by put in larger and larger habitats to get used to the outside and then re-introduced.Whilst 200 a year have been released and after 30 years, there are only 300 survivors. The measures of success seem to be unsuccessful, but in the measures of whether the species would still exist, it has been successful. This is an example of something that humanity needs to interfere with to keep this species afloat. They are not yet self-sustaining and viable in the long term. There has to be intervention to re-locate if certain areas have fewer animals.Recently, there are doing even more to help this program by cloning ferrets, but would this really be considered a success? We are working very hard to keep this species alive but would it be more ethical to let them go and focus our efforts elsewhere? These ferrets died due to a plague from fleas in prairie dogs, so do we have a responsibility to keep them alive there? It is a complex argument for either side.Ferrets are a predator and have to be raised to kill. If they cannot prove an ability to kill, then they may not be able to be reintroduced. It is a difficult tightrope to walk and genetic diversity is a problem for these ferrets. According to scientists, in a decade, they could be fine to survive without human intervention and too many other effects on the environment but it is always tough to know what unintentional consequences may have occurred as a result of this.There is no right or wrong answer. Just benefits and negatives for both sides and it has to be case by case for any other animals. At least there is a push to reverse the effects of human negligence in the wild and that should be appreciated no matter the outcome.
