Karner Blue Butterfly
Ecological succession and Lupine distribution
1. Lupine can only survive in areas cleared
by fire or other disturbance
2. Either too much shade or sun will kill it
3. An area clear of undergrowth but partially
shaded by trees is best, but this is rare in
todays environment
4. Day in and day out, ecologic succession
tries to destroy the Karner Blue Habitat

Four Important Questions

Case Study
Karner Blue Butterfly
Troublesome issues
1. Number of preservation areas
Which method sounds better to you?

2. Cost

Case Study
Karner Blue Butterfly
What is dependent on the Karner Blue for
existence?
If a dependence on Karner Blue exists, then is
that species important to the ecosystem?
16
To date, it has not been shown that this
species in any way effects an ecosystem- that
was in 1992.
17
Note No other species is dependent on lupine
and lupine is not dependent on the Karner Blue-
1992
However, an entire field of science has developed
and is known as Pollination Ecology has
revealed many similar plant/butterfly
relationships.
18
What is beauty worth?
or ecosystem function?
19
For the Karner Blue Butterfly
Conclusions
Cost and inconvenience for recovery of the
Karner Blue Butterfly is endured primarily by
the people living near it, not the populace as a
whole.
I hope that butterfly is worth it, I havent
been outside after dusk in a month, said a
resident of Wilton, New York
But wait!!!!!!!
