As Chris Kline pointed out, the Desert Botanical Garden in Phoenix
acquired all necessary permits to release these [California]
monarchs as a part of their monarch exhibit. I was not involved
in any of this; i.e. not involved in the shipping of California
monarchs to Arizona. So Bob Pyle is mistaken in infering that
I was involved and in infering that the activity was illegal.

I disagree. Monarch biologists such as Dr, Lincoln Brower appear to
have just arbitrarily assumed monarchs did not breed and migrate
within the Great Basin, Rocky Mountains, western Great Plains or
other mid-to high altitude regions. They assumed the western US
deserts and mountains were a physical barrier to monarch movement.
You can see this in this in a 1993 map Lincoln drew which is NOT
based on the results of monarch transfer experiments:

In reality, monarchs are locally common throughout much
of the Great Basin, Rocky Mountains and western Great Plains
Sometimes so common, in fact. that in 1997, when I was collecting
monarchs for Dr. Sonia Altizer, I was able to catch DOZENS
of monarchs at multiple locations around the western USA.
Here are some of my ONE DAY catches that are published
Grand Junction, Colorado: 25 monarchs
Salt Lake City, Utah: 30 monarchs
Reno & Minden, Nevada: 21 monarchs
Umatilla, Oregon: 11 monarchs
Outlook, Washington: 32 monarchs
El Dorado, Calif.
