Battles over Invasive Plants

The disagreement is at my normal high level state, but can be easily
understood by the three way challenge of tamarisk, southwestern
willow flycatcher, cotton willows, with a dab of water issues
thrown in.

Here in the east we have song birds and thistles, non
native.  The non native thistles can supply seed, but not reproductive protein. 
Of course the native plants are mostly gone so the question is what to
do.

This pits wildlife folks who are looking at preserving endangered
species for as long as they can, and invasive species managers who realize that
the damage long term is catastrophic for more than just one
species.

Invasive species are the second largest reason for the
extinction of species right after development.

Next email from JPT:

The question is one of ecosystem interactions, and the wildlife folks are
fixated on strong interactions while the invasive folks are fixed upon weak
interactions.  One definition of a sustainable and functioning ecosystem is a
system with many weak interactions and few strong interactions, so the complex
wicked problem has no linear solution, see my writing on a wicked
inconvenience :)
