I have a hard time with this one and spent some time sending an email to Ruth (project research lead) last night.
Essentially they are conducting a study to find out whether or not there are higher levels of pollutants in the middle of a high traffic snowmobile trail or in a wilderness area, and how those levels of pollutants impact may aquatic species.
I questioned Ruth....Dr. Ruth that is....about the methods or sampling, test plot locations, times of samplings, methods of analyzing collected data, and locations of adjacent headwaters in relationship to the test plot locations.
If they take samples in the middle of a trail on the middle on a Saturday afternoon where there could possibly be high(er) ammounts of pollutants, but that trail is located 1+ miles away from the nearest headwater is it really going to have a negative impact on the local aquatic species? I think not. However, i'll be polite and let her get back to my email before I jump to conclusion.
It's pretty easy to read through the lines on this one. The research is setup to negatively reflect on the snowmobile community. It's like taking a sample of levels of oil in the middle of a lane on I5 and comparing it to a side street in Milton. Of course you'll see higher levels of pollutants.
Pretty biased study if you ask me...to be continued
