Cottontail Rabbit

Native species refers to animal or plant species thriving in the
ecology they evolved from, where exotic species refers to plant
or animal species living outside their ecological zone, which
existence in the present ecology is as a result of human activity.
Ecology on the other hand refers to interactions between the
living organisms and their environment. This means that, there
is usually a change in interaction when a new species is
introduced in a new ecological system. The change in
interaction affects both the introduced species and the
indigenous species. The term exotic species culminates from
European exploration, colonization and settlement outside their
continent. They carried with them plants and animals originally
thriving in their original homeland to their new settlement
areas.
This paper focuses on animal species that can be found from
Canada to South America and, in the United States, from the
East Coast to the Great Plains and New England. Cottontail
rabbit is the common name of a group of rabbits with distinctive
"cotton ball" tail for which they are named. They fall under
genus Sylvilagus (Hoffman and Smith, 2005).
According to nature ranking status, the species identified above
is endangered calling for a special concern of becoming extinct.

3. There is little recorded information about this species due to
dominant species in its ecological system. There are many
explanation for this. For example, it has been shown that the
habitat where the Cottontail rabbit survive is being destroyed.
In addition, the other species are more adaptive hence this
particular species is threatened by habitat loss. These other
species sharing the same habitat with Cottontail rabbit include
squirrel and chipmunk (Hoffman and Smith, 2005). Sources
indicate that these other species have a competitive advantage
when it comes to eating capacities. For example, it has been
shown that the two species mentioned eat sitting up on their
hind legs, and can hold food with their front paws while
spinning it in circles to consume it quickly. To this end, hairy
sunflower species is as a stress of overcrowding of its habitat.
Cottontail rabbit is also threatened by the habitation loss with
evolution of geographical time on the aspects of physical and
climatic processes experienced over the years. These aspect cuts
across climatic change in soil composition due to erosion and
other soil processes and the species interaction with other
species that has resulted to overcrowding in the ecological
system. Cottontail rabbits require a habitat of young trees with
plenty of grasses, shrubs and brush, i.e. a young or immature
forest (Hoffman and Smith, 2005). However, in New England,
for example, much of the land where the species exists has been
turned into mature forest, with large, tall trees and not as much
ground-level undergrowth (Hoffman and Smith, 2005). This has
discouraged the population of rabbits.
In the aspect of the loss of prey base, hairy sunflower has lost
the prey base to adaptive squirrel and chipmunk. These species
can easily adapt and have a better defensive mechanism as well
as eating capacities. The fact that Cottontail rabbit depends on
its hearing also make it less adaptive compared to other species.
The increased stress further reduces the likelihood of survival.
The species has also suffered increased competition from the
native species in the ecological system. Competition comes in
terms of struggle for access to shared food such as bushes and

4. twigs. For the protection and conservation of this endangered
species, measures should be put in place to protect the species
ecosystem. This is through promotion of grasslands and oak
savanna and oak barrens. This would lay the foundation for
perpetuating prairie openings that maintain habitat for this
species.
