The
picture depicts a bull elk amongst spring foliage in Rocky Mountain National
Park. These plants are a life-line in the times of need for and elk. When the
snow is at its heaviest and the elk are at their most vulnerable and meek
state. When you enter the park now you can see that the plant life has changed drastically
and there is no longer the thick under-growth just lodge pines and striped
aspens. The landscape stripped bare of nutrients.
This is a way that the population can thin out itself. It
could possibly balance the numbers of the herds if the range of the herds wasn’t
so wide. However with so much space they are able to come down into the plains
and the graze the fields of the ranchers. They even come into the fields of
farmers and eat the crops such as hays, corn, and wheat.
Without
the natural death of some of the members the herd numbers explode. The elk have
a hierarchy were the strongest males compete for the right to breed over their
range. When the number of males of the herd far exceed the females it is almost
impossible for the bulls to drive the juveniles out of the group when mating
season arrives. This leads to a situation where the weaker of the species is
able to mate with multiple cows and create offspring, stopping the lineage of
the strongest. This makes a subset of weaker offspring more susceptible to disease
and predation.
