No doubt at all the 'lineage' aimed for is cumalative, it is whether among a few localised
apiarys in say a 10mile radius one can maintain soverignity that where the 'project' falls
over. You only need one newcomer bringing a dozen diverse colonys into the area and your
definitive efforts are shot to shite, or one of your group to miss a step once.
The Rottnest Island project avoids that probability in selective isolation - I provide a loose
look into that operation. The Kangaroo Island "pure Liguruan Queen" claim is highly
questionable for exactly the reasons stated above - up until legisalation some time back it
was the case any amount of either queens or colonys were brought to the Island in
'improving' the bees. A similar story is attached to the AMM bees brought into Tasmania.
Oddly enough it is widely accepted those bees are now geneticly diverse yet a new wave of
entrprenures hang off the KI myth of isolation.
The breeder we used to buy our requeen stocks from - back in the day - operated roughly
how you describe, I personally assisted in setting that "clear zone" in relocating ferals, and
is how our apiary then got started. Some years my senior, after better than 49years as a well
respected supplier of a line of modified Italians he no longer warrants supply is his 'line' as
the bubble that was then around his operation was breached back in 2005 with urban sprawl.
Which brings another aspect to your project - as you can restrict other facets of your
beekeeping to strive to achieve what you hope for but from factors not in your
control it will get shot to shite inside of two seasons, leaving you with nought but a memory.
