I guess this a tradeoff. When I was kid in the mid 1960's I lived in
San Lorenzo just a few hundred feet away from what is now the back part
of Sky West Golf Course. At that time it was a large open field and
it was harvested for hay (I guess) once a year in the early spring. A
few of us collected butterflies and one friend's house backed up to the
field. We'd frequently go out there as there were lots of butterflies.
Milkweed grew there and I found Monarch caterpillars all summer. To
this day I don't know what kind of Milkweed grew there. It was a thin
leaf, low growing variety.
With the golf course we lost a habitat for many species (not to mention
the snakes and lizards we'd find) and replaced it with an overwintering
site for Monarchs.
