[HALO] If the Forerunners saved samples of different species to repopulate worlds, why didn't they save any of their own species?

Or did they and I'm just not catching on?

The Forerunners were meant to survive by taking refuge on the Ark(s) which were outside the range of the Halo Array. Gravemind attacked the first Ark, destroyed it, and killed most of the surviving Forerunners. The few remaining survivors safely activated the Halos on the second Ark, but they went into exile and left the Galaxy on their Great Journey (of atonement). Their fate is uncertain but 343 Guilty Spark stated that they are dead.
