NWHC submissison criteria general guidelines

Before responding to a mortality event, wildlife professionals should first consult with NWHC epidemiologists and if applicable their respective Federal, State or Tribal natural resources agency wildlife health program to discuss response options. These wildlife disease experts can provide guidance on which specimens to collect, how to collect and best preserve specimens to maximize their diagnostic value, and the health risks and authorities needed (such as permits).

All submissions are managed on a case-by-case basis and must be submitted through, or in consultation with, an appropriate federal, state or tribal agency and the NWHC point of contact. Submissions from the public, rehabilitation facilities, universities, private or zoo veterinarians, diagnostic laboratories or other entities are not accepted without prior consultation with the NWHC and appropriate federal, state or tribal agency. If you are a private individual or entity with a mortality event to report, please contact your state department of natural resources or state agency of game and fish. A list of state and federal agencies can be found at
