[permaculture] Exotic Plant Erradication

I appreciate this reply, Kirby....

I saw the pics of the water hyacinth and thought, "that's more of a solution
than a problem"  If the water wasn't so "nutrient rich" the water hyacinth
wouldn't be there in such numbers - it can only multiply in proportion to
available food...it's there to clean the water.  Same deal for the much
maligned zebra mussel around here....Native fresh water mussels have been
disappering because man has altered the conditions in which they live -
Zebra mussels are moving in to fill the void. Bless 'em !
I Also always think of  Vermont's state flower which is the red clover..
it's a non-native, invasive exotic, and where would we be without it ?

Last thought : NATURE DOESN"T MAKE MISTAKES ! She knows exactly what she's
doing -
