Reserve 2 is one subunit in a ring formation. There is a hole in the middle of the subunit in order to create some sort of separation and differential interactions between the ferrets. This intended dispersion, due to the ring formation, was created to reduce the disadvantages that a single unit reserve obtains. An example of a disadvantage to a single unit reserve would be that the entire population is affected when an allele is lost, instead of a single subpopulation. Yet, I made Reserve 2 a single unit in order to promote more breeding between the ferrets. The increased breeding results in higher heterozygosity, decreasing the risk of genetic drift and the loss of alleles.
