According to 343 Guilty Spark, the Halos will destroy all sentient life within 3 radii of the galactic center. This means things like plants and trees will be left alive, and possible some types of animals, depending on how the definition of sentience is interpreted. Other than that, we don't know what happens.
We don't know what exactly happens when the Halos fire, so we don't know if anything within 3 galactic radii could be considered "safe," whether they are in normal space, slipspace, or some other dimesion that exists within the "space" around our galaxy. Nor do we know if the Ark is a means to protect certain beings from the Halos effects or not.
So far, we don't have any definitive proof whether there is a connection between "Reclaimers" and the Forerunners, besides 343 Guilty Spark calling the Master Chief and Miranda Keyes Reclaimers.
