Beyond the obvious need for preservation of Endangered and 
Threatened Wildhife, we have concern for other species which 
unfortunately may be <mminent candidates for the abyss of 
extinction. We need to evakruate these species more thoroughky 
and monitor their populational changes more ckhoseky. These 
animals may be on State endangered Lists or may be region- 
ally depleted. The Forest Service has ckassified animals of 
this status in an additional category: Unique Species. 
Although presentlhy in somewhat Less dire straits than the 
designated Endangered and Threatened Species, these "Unique" 
animals may nevertheless be in need of our assistance. Often 
they oceur in such Low numbers and/or in such a restricted or 
Specialized habitat‘that they may be extremely susceptible to 
eLimination. The subsequent report concerns unique species 
Of f4shes on the Shawnee National Forest, and documents the 
Forest's concern for the preservation of these nare animals, 
as Something beyond a hand-wringing display of apprehension. 
They have taken the bit in their teeth and spent of their Limcted 
wikdlife funds to get expert evaluations of the status of these 
fishes. Further, they have taken the advice of these experts 
and have instituted recommended protection for these species. 
The Shawnee National Forest has property interpreted "wildlife" 
as a term encompassing all wild animals -- not game species 
alone. None of the 41shes investigated: in this contract study 
are Of any significant anterest to the angler. I appreciate 
the excellent piece of work the Illinois Natural History Survey 
has done on this study, and I am pleased with the Shawnee National 
Forest stash for assuming habitat responsibilities for all 
wildlife on the Forest.
