In the era of axe, hand labor
and horse drawn plows, cottontails thrived on the edge, but when small farms were
abandoned, the land generally reverted to be more favorable towards white tailed deer
(Bolen, 1995 pgs257, 259). From that era, they became classified as Farm Game.They
are the most popular game mammal across the United States (Burger, 1973 pg35, 48). Harvest
of the cottontail numbers well into the millions each year without having a lasting effect
on the size of the population (Bolen1995 pg27). Water plays a big part in the number of
cottontails harvested. As precipitation, water acts to protect cottontails from hunters by
being under cover and discouraging hunters (Bolen, 1995 pg192).
Agriculture has seized nearly all of the richest soils. We established in the
Reproduction section that fertile soils are important to yielding strong,
numerous litters. Having a hunting season harvest well into the millions, biologists often
face the task of managing for populations that are less than optimal and do not yield a
high number of litters (Bolen, 1995 pg93). Even so, the hunting season has not taken a
high toll on the number of cottontails; they continue to thrive in high numbers.
Fire is only a problem for cottontails during nesting season. At that time,
fire may destroy nests and young. During other seasons, fire has little impact on
cottontail populations. They maintain trails and remove enough herbaceous vegetation at
the base of brush clumps so that the cleared areas become effective firebreaks (Bolen,
1995 pg308).
Farms are good habitat for cottontails, with the brush and edge. But
pesticides and tractors have been known to kill rabbits. At the invention of headlights,
nighttime mowing increased mortality of all species in the area fivefold over the daytime
rate (Bolen, 1995 pgs272, 269-260).
The cottontail also has many predators and plagues. Common plagues are virus
caused skin fibromas, warble-flies, tape-worms and tularemia (Burger, 1973 pg49).
