Yeah, I'm not sure what they're getting at with that. The only thing I can think of is cloning individuals with rare genotypes and introducing them into different breeding populations - like if the population is fragmented, cloning enough individuals to have some of every rare genotype in each population. Or, cloning individuals in zoos/captivity that have rare genotypes but are too old to breed or sterile for some other reason, or can't be transported. I suppose you could even (depending on how well this technique works) clone recently killed animals that have been siezed from poachers or had to be killed for human safety reasons, to preserve their genotypes.
Oh, just thought of this - it could be used to help preserve heritage breeds of livestock (I recently fell in love with the wool from Jacobs sheep - I'm a textile craftsperson - it's some of the nicest to spin I've ever gotten to try.)
