If you
are like me, then coonhounds play a big part in your life. I can spend hours
with my friends talking and thinking about the dogs we know & how good or
bad they are. It occurred to me the
other day that coonhounds arent much fun without raccoons. As I thought about
this, I realized that I didnt actually know too much about raccoons. Through
trial and error I have found some areas that have raccoons and these are where I
like to go hunting. Along the way Ive noticed that one year there seems to be
hardly any raccoons while the next year there will be bunches. Thats about
it? Ive spent years chasing raccoons and all I know is that some places have
raccoons and there may be more or less of them in any given year! I decided to
see if I could find out a little more about my furry friends.
When I
set out to research this topic, I was primarily interested in finding the
raccoon populations for my part of the country. So how does one go about
determining raccoon populations? My first contact was Bill Berg, the furbearer
research biologist for the
Minnesota DNR.
Bill
advised me that furbearers are particularly difficult to inventory because of
the enormous area they inhabit and the difficulty in observing them. No official
attempt is made on the part of the DNR to estimate the raccoon population in
Minnesota. Bill went on to explain that some population information does exist
for our area in the form of harvest data and scent station surveys.
When I
got a look at raccoon harvest numbers didnt they didnt really impress me
too much. These statistics are derived with calculations that use hunting
license sales figures and DNR survey forms. The true number of raccoon hunters
and accurate answers to the surveys are essential for this system to work. Even
the DNR questions the validity of this process and is investigating
alternatives. Using this system, estimators believe that between 170,000-200,000
raccoons are taken annually in Minnesota. Harvest numbers are just that, a
record of how many raccoons were harvested. So you learn nothing of actual
raccoon populations from this.
Scent
station surveys on the other hand give a little better information. The
official name of this program is the Interagency Cooperative Scent Station
Survey. Interagency is the key word here. A variety of organizations all over
the state of Minnesota cooperate in setting nearly 4000 scent stations and
recording the results. A scent station consists of a 3 diameter circle of
smoothed earth with a fatty-acid scent tablet placed at the center. A line of 10
scent stations are placed along unpaved roads at intervals of about 1/3 of a
mile. A line will be set for 1 night each year between late August and
mid-October. On the following day the presence (or absence) of tracks are
recorded for individual species. These records are compiled each year into a
number called the scent station index. Over a period of time a trend will emerge
from these index numbers. That is, there are either more or less raccoon tracks
each year. While this still doesnt give an actual population, it is possible
to know if the population is increasing or decreasing. The data also gives some
insight into the distribution of raccoon populations throughout the state.
Bill
provided me with a copy of scent station survey summary through 1998. The data
has been collected over a period of 23 years and indicates that the raccoon
population has increased almost every year. The instance of raccoon tracks has
risen a staggering 700% in the farm belt located in the southern and western
parts of Minnesota. During this same period, an increase in tracks of about 250%
can be seen in a transition area of the state that lies between the farmland and
the forests of the north. The
forested lands in the northern part of Minnesota have experienced only a slight
increase in its scent station index. So what does this mean? Well, if in 1976
you lived in Minnesota farmland and you had one raccoon in your woods, you might
well have 7 raccoons there today. Bill guessed that the raccoon population in
Minnesota is far in excess of 1.5 million.
So
much for Minnesota, what about the rest of the country? Well, here is some
information I was able to in a few other states.
The Michigan
DNR provided information very similar to that for Minnesota. It was
stated that raccoons occur in all counties in Michigan and it is estimated that
2-3 million raccoons are in Michigan at the time that hunting and trapping
seasons begin each year. Notice the low and high estimates at 1 million apart,
it occurs to me that what they are saying is, I dont know for sure how
many raccoons there are, either a lot, or really a lot!
The
Missouri Conservation department
thinks their raccoon population has increased over the past decade and currently
is near 2 million. While the Nebraska
Game and Parks had this to say, In the 1940s, a continent-wide population
explosion occurred as raccoons expanded their range and increased in abundance.
There were at least 15 times more raccoons in North American in the 1980s than
in the 1930s.
At
first I was very pleased to learn that the raccoon population was doing so well.
I like chasing raccoons with my hounds and the more of them around the more fun
I have. Unfortunately, as I continued to learn more about raccoons I encountered
some unsettling information. Raccoons may be fun to chase, but their increasing
population is having its negative effects. Raccoons are predators and they can
devastate many species of wildlife. Ground-nesting animals, such as ducks,
pheasants and turkeys, are especially vulnerable to their hunt. Several kinds of
turtles are probably headed for extinction, largely because of raccoon
predation. One study site in northern Michigan reported that raccoons are
getting 90 to 100 percent of the wood turtle's eggs.
Raccoons
are now in far northern Manitoba and Saskatchewan, and compounding problems for
waterfowl managers there. One Michigan biologist in Michigan biologist Joe
Johnson was quoted the raccoon has all of the makings of an environmental
disaster.
So raccoon populations are rising and that turns out to be a bad thing. OK, then that should make coonhunters pretty popular, right? Well, probably not. As you may already know, animal rights activists have turned public sentiment against wearing fur. They are now working hard to stop hunting and trapping. Raccoon hunters and trappers tend to be portrayed as savage brutes. It appears now that raccoon populations are controlled mainly by disease and road kill mortality. Hunter and trapper harvest have some effect but the raccoon population is still growing every year.
