Importing game to Washington

[CarbonHunter]

Does anyone know the reason why you are required to notify the WDFW within 10 days of importing a cougar or bear harvested in another state?

I understand their reason for deboning deer and other species because of CWD but I’m drawing a blank on the reason for bear and cougars.
