You are right John they prefer the more sandy dry country,they along with other critters often share
rabbit warrens. Large adults are fairly safe from predators but juveniles fall prey to the usual suspects.
Snakes can be an issue with the ferrets so we do proceed with caution. Only lost one ferret to a snake in twenty odd years so (touch wood) not too bad.
The country shown is as John describes, low remnant Mallee scrub. I do a lot of work in these types of areas where native plant reveg. and preservation is the order of the day. The "updated" traditional methods are much preferable to gassing etc in these areas as "off target" kills are avoided. eg goannas and other natives.
Will post more pics etc soon...bit busy catching rabbits.
My apologies to the "augmented" gorgeous blond!
