What mammals could be affected by the rodenticide?
There are no land mammals on Rat Island. A Steller sea lion rookery is located on an off-shore islet and sea otter and harbor seals can be found in the area. These are all large, carnivorous animals so it is extremely unlikely that they would eat a grain-based bait pellet should a stray piece of bait end up in their vicinity. It is unlikely that they would be adversely affected by the proposed action. More details can be found in the environmental assessment.
