outlined in Appendix F. Results will be analyzed separately for the project 

 ared and the control area. 



Bald Eagle Survey 



The Kootenai River between Libby and Troy will be surveyed from Highway 

 2 for bald eagles three times in Janaury, following the methods of Meyer 

 (1979). These data will be treated separately from bald eagle information 

 obtained during general surveys and riparian habitat censuses. 



Harle quin Duck Special Studies 



In addition to surveys made during riparian habitat censuses, special 

 searches of the Falls area for harlequin ducks will be carried out each day 

 in the field in June and August. In June, emphasis will be placed on deter- 

 mination of total population size and the number of pairs present; in August, 

 emphasis will be placed on search of likely brood-rearing habitat for broods. 



Bighorn Sheep Counts 



One day each month, a special search of the cliffs north of the River 

 between Libby and Troy will be made from strategic viewpoints along Highway 

 2 using a spotting scope. An estimate of the minimum number of sheep known 

 to be present will be recorded. All oberservations will be recorded on field 

 maps and data sheets. 



Bighorn Sheep Tracking 



On two different days each April, the north shore of the Kootenai River 

 adjacent to known bighorn sheep range will be walked and searched for tracks 

 or other evidence of bighorn sheep use. These data will be recorded on 

 standard field maps and data sheets. 



Amphibian and Reptile Search 



At least four hours will be spent each month during April, June, and 

 August in a search of likely habitat for amphibians and reptiles. 



Small Mammal Trapping 



Two snap-trap lines (each consisting of 25 stations of two traps each) 

 will be run for three consecutive nights in August (beginning in 1980), one 

 in riparian cottonwoods at the head of the Falls and one in adjacent riparian 

 grassland. Capture data will be recorded on standard data sheets (Appendix E)
