At Risk Species

Tier I species are those that are globally or nationally most at-risk of extinction. Tier II species are those at-risk within Nebraska while apparently doing well in other parts of their range. For a complete explanation of how species are evaluated for “At-risk” status, refer to The Nebraska Natural Legacy Project. Wildlife listed as Tier I or Tier II at-risk species will receive primary consideration as management practices are being evaluated for all PRBE properties.
