There really is no need to choose, as rattlesnakes do quite well in 'disturbed' habitats. The problem comes when people kill them for being rattlesnakes.
I was walking the trail at my cousin's ranch last April, and on the way out from the house we saw a rattler and just stepped around it; didn't see any reason to kill it.
By the time we came back it was dark, so I was using my flashlight to check where they normally coil up and wait for prey. I still didn't see it, but my nephew jumped and stepped back. I thought he probably had a damn good reason for doing that, so I did the same.
He said the rattler missed my knee by about 1/2". I was wearing my boots, but the tops don't go past mid-calf, so boots or no boots, I'd have been hit. I was lucky that time, but if I do that again, I'll have some real anti-snake gear.
