Appendix 9: Tier II at-risk species.

Tier II species include those that did not meet the Tier I criteria but were ranked by the Nebraska
Natural Heritage Program as either State Critically Imperiled (S1), State Imperiled (S2) or State
Vulnerable (S3) (see appendix 4 for explanation of ranks). Because of the large number of at-risk
plant species, only those species listed as S1 or S2 are included in the following list. The Tier II list is
used to help prioritize conservation planning/actions and does not have legal or regulatory
ramifications. Tier II species are typically those that are not at-risk from a global or national
perspective but are rare or imperiled within Nebraska. Conservation of these species is needed to
ensure they remain a part of Nebraska’s flora and fauna.
During the development of the Nebraska Natural Legacy Project, the “S-Ranks” were reviewed and
revised for amphibians, birds, mammals, fish, reptiles, mollusks, plants and a limited number of
insects.
The Tier II at-risk species lists will be periodically reviewed and revised by taxon experts. This
revision will occur on an on-going basis as new information on the abundance, distribution, and
population trends becomes available, with an overall review at least every five years. The Tier II list
was reviewed and revised with input from taxon experts in workshops held in 2010.
