actually, in Florida we use the Uniform Mitigation Assessment Method which scores both impact and mitigation wetlands on the functional loss/ gain for each permit application. If this purchase is being made to use the land merely as preservation mitigation, the ratio will end up being much higher (more like 30:1) as the value of the gain for merely preserving existing wetlands is much less than you would get for enhancement or restoration activities. The area of this land purchase is within the Reedy Creek Floodplain and is in pretty good condition with limited development surrounding it, so its already a high functioning wetland and it will receive less credit than say the wetlands out at the Disney Wilderness Preserve which has had large wetland creation and restoration projects to get the mitigation credits. Also, wetland mitigation does not typically have anything to do with listed species mitigation, unless it was permitted as a joint mitigation/species conservation bank like some in South Florida with wetland/panther combo credits.
