This is a short video displaying a small cattail marsh here in Michigan that is suffering from the non-native Purple Loosestrife plant choking out the native cattails and ultimately taking over the area. They are very prolific in that their flowers or tassels release millions of seeds from each plant. These seeds fall into the mud or are blown thru the air on the wind. Animals will walk thru the mud and marsh and transport the seed rich mud from one location to another. The cattails have no chance against their infestation. Waterfowl and many other animals are directly affected by these plants and their destructive takeover. The Purple Loosestrife is non-native to not only Michigan but the entire North American continent. Originally from Europe it was introduced to N. America in the early 1800's in the ballast of ships and for medicinal purposes. It quickly spread thru all of Canada, US, and Mexico. My apologies for misstating the name of this plan in the video . Sometimes you get a word stuck in your head and can't get it out. I called in Purple Looseleaf . . . sorry.
Anyway I hope this video helps you classmates to understand how important it is to be careful when introducing non-native plants to any area. You must check with experts in the area to find out what should and what shouldn't be planted. Signing off for now. . Bob
