Thanks Petrus
Using carnivore odours as herbivore repellants nearly always fails becuase the herbivores very soon learn that although the area smells of predators there are actually no predators around, and so they go back to business as usual. A high profile plan to use dingo urine to repel kangaroos and wallabies sank without trace when even real dingo urine did not have a reliable effect, repellants have no long term benefit in stopping caribou from licking the salt off roads, lion poo was the basis for a deer and rabbit repellant that looked promising and was commercialised, but is no longer on the market as far as I know, and there are several others.

Do you have a reference for the Umea work, please.
The BioBoundary is
not based on repellancy - in fact we expect that over distances of tens of meters the artificial scent marks will
attract wild dogs but that at landscape scale (kilometers) a Bioboundary will influence wild dog movements in the same way as natural wild dog scent marks.
Because a BioBoundary is not a repellant and works a large scales, the fact that small scale movements of coyotes are not influenced by artificially deployed scent marks should not be interpreted as evidence that a BioBoundary will not work;
