The Problem of Invasive Species

I'm often asked what is the most pressing problem 
for our Great Lakes. 
My answer:
Invasive species.

When a new species is dropped into an ecosystem in which it has never existed, it often has a huge survival advantage and can toss the entire system out of balance for a time. 

As I've walked the shorelines of our vast inland seas, I've often seen evidence of the destructive power of invasives.

While vigilance and legislation (e.g. strict ballast water treatment laws) can help prevent transport of new species into the Great Lakes Basin, what can be done to control them once they have established a hold in the lakes?

INVASIVEORE.ORG has some ideas...
and recipes!

From their website:  
Our mission here at Invasivore is to be your one-stop guide for devouring Invasive Species, those organisms which have been moved around the world, damaging their new surroundings.  Think of it as reasonable revenge for the harm these species cause.  The word “invasivore” comes from combining “Invasive Species” with the latin for “devour” as in “carnivore”.  Thus invasivore = one who eats invasive species.
From prehistoric times, humans have had an amazing track-record of severely reducing the populations of species we eat.  Indeed, it seems that much of the time we can’t stop ourselves.  Can we tap that hunger to reduce the impacts of harmful invasive species?  We think the answer is Yes!

I was discouraged to see so much of the invasive grass -- phragmites -- along the shores I've walked so far.  

It was along the Great Lakes, along inland canals and ditches, along smaller lakes and large rivers.  

Invasive species have changed and warped and altered the ecosystem of our Great Lakes.  I spoke to one woman who remembered that the shores near the town of Sebewaing were free of  phragmites a decade ago.  Today the waterways are choked with this invasive grass.  
There had a to be a window of time when the species was first introduced and could have been easily controlled and then eradicated.  That window of opportunity has passed and now eradication will take a concerted effort over many years.
