Dipole in trees a fire hazard?

I live in a heavily wooded are in Georgia. The lot my house is on is very steep with tall trees making antenna work difficult. I have a 135 foot wire dipole in the trees fed by 450 ohm ladder line than I use on most HF bands besides 160 Meters. The antenna has become partially covered by vines on one leg. I know this will result in an imbalance. I prefer to operate RTTY at 500 Watts for contests. I have stopped operating out of concern that the Dipole could be a fire hazard. Is this a hazard of am I being overly concerned?
Tnx, de Mike AJ4CG

You could install additional insulators to pull the antenna away from the vines.

Zack - thanks for the reply but I am trying to understand if there is a fire risk.

A few anecdotal stories of fires.

If you transmit with more power than a small soldering pencil uses; 30 Watts, extra precaution is needed. One only needs to use appropriate antenna insulators. I have seen a high power station ignite a tree, but usually it was done on purpose to amuse other Radio Amateurs. I have seen and heard voices from the corona at the end of an antenna.

fun is.
