E (Endangered) - Taxa in imminent danger of extinction or extirpation 

 and whose survival is unlikely if the causal factors presently at work 

 continue operating. 



T (Threatened) - Taxa believed likely to move into the Endangered cate- 

 gory in the near future if the causal factors now at work continue op- 

 erating. 



R (Rare) - Taxa with small populations in the state which, though not 

 presently endangered or threatened, are potentially at risk. 



SC (Species of Special Concern) - A species that does not clearly fit 

 into the endangered, threatened or rare category yet which, for certain 

 reasons, warrants special attention. 



SU (Status Undetermined) - Taxa which are suspected of falling into one 

 of the above categories but for which the available data are insufficient 

 to provide the basis for a decision.

E (Endangered) - Are those species in danger of extinction throughout 

 all or a significant portion of their range in Alabama. Endangered 

 species are those whose prospects for survival are in immediate jeopardy. 

 An endangered species must have help, or extinction and/or extirpation 

 from Alabama will probably follow. 



T (Threatened) - Are those species which are likely to become endangered 

 within the foreseeable future throughout all or a significant portion 

 of their range in Alabama. 



SC (Special Concern) - Are those species which must be continually 

 monitored because eminent degrading factors, their limited distribution 

 in Alabama or other physical or biological characteristics may cause
