I read that one should use a non-copper type wire to tie on staghorns to their new location. Does anyone know the reason why?
It's just that I have actually used bare copper wire and now I'm worried that may be causing the plant damage.

Many plants are very sensitive to copper. Being in direct contact will kill some completely. In fact, that is an old remedy for some stubborn trees. If you can find copper nails anymore, you can drive them into the tree in several locations to kill it off completely.
I recommend anything outside of copper... even aluminum, which I don't recommend for a long term solution. Plant ties are very inexpensive and can be purchased online even. It is best to avoid copper, altogether. It will lead to a dead plant.
