Dan O, Thanks for the support. You present some great facts.
1sagittarius, If you ASSUME that the saw tooth will be as detrimental to the environment as some of the less desirable exotics such as multiflora rose and the zebra mussel than you are correct. The problem is that you are asumming. Can you site any studies that support that the saw tooth will be an detrimental exotic? On the other hand what if it fills a niche that is currently missing in many of our forests as sited by Dan O? Once again I am only in this to talk to others about something I love and to learn from others, not cheap and classless shots.
