The public, however, still thinks the eastern monarch migration is in
decline and could soon become extinct because that's what the
academic & conservation community has been directly or
subliminally telling them every year for the past 16+ years in
various articles, websites and press releases. Recently, for example,
educator Elizabeth C. Howard wrote the following:

"From a monarch's point of view, our midwestern breadbasket
is becoming a biological desert."
I profoundly disagree with Elizabeth's statement. I cannot
think of any place in the whole world where monarchs are
more abundant than in the upper midwestern breadbasket.
Where else in the world can one see thousands of recently
emerged monarchs in flight like this?:

Nectar is also plentiful in the upper midwestern breadbasket
because some of the crops themselves bloom and provide nectar
(e.g. alfalfa and red clover):

Milkweed and nectar plants are also plentiful along the margins
of crops and roads in the upper Midwest:

The article also fails to mention that size of the monarch
overwintering populations in Mexico has not declined since
the time (approx. year 2000) when herbicide tolerant crops
and Bt corn became widely adopted by upper midwestern
farmers: http://www.saber.net/~monarch/mexpopss.jpg
The annual Cape May monarch census also shows no pattern
of decline:

Lastly, the article fails to mention that urban sprawl isn't much
of a problem for the monarchs in the upper Midwest because
the human population in the rural farming areas (e.g.southwestern
Minnesota) isn't hardly growing and is actually declining in some
cases.
