It seems from the papers the anti-deer folks are divided between two categories — lethal cull or nonlethal measures including fencing.
I feel strongly that one nonlethal option that has not been thoroughly explored is the use of low amperage electric fences of perhaps one strand of wire.
A simple one-strand wire fence can be adjusted to a low enough amperage to be harmless to humans and animals but still have enough snap to be a deterrent to deer.
I have learned that currently there are no bylaws that prohibit electric fences in Oak Bay, but that such a bylaw is in our near future. I appreciate that there may be liability concerns that need to be investigated. However, such a bylaw should specify the allowable number and length of wires plus levels of voltage and amperage.
