Appendix C. Circle West Baseline Study Waterfowl Observation Data Sheet: 

 Instructions for Use. 



OBJECTIVES OF STUDY : 



(1) For Al 1 Species . To determine dates of earliest arrival, peak of 

 movement, and end of movement for spring and fall migrations. 



(2) For Breeding Species . To determine: the importance of waters in the 

 study area as nesting nabitat; size of breeding populations in the study area; 

 nesting habitat requirements; dates of nesting; clutch and brood sizes, pro- 

 ductivity. 



(3) For Migrants . To determine the importance of waters in the study area 

 as resting or feeding nabitat. 



CATEGORIES OF DATA: 



(1) Level . Indicate in this column the general location of the observation, 

 as follows: 



- Within CMR Wildlife Range 



1 - Within ll'a-section proposed mining area 



1 - Within 75-section study area but outside proposed mining area 

 3 - All other areas in the reconnaissance level study area 



ilote: Tliis column was deleted for tlie monitoring study after Marcn, 1973. 



(2) Date : List only for the first observation of the day, o>" at the top 

 of a new data sheet. 



(3) Observers . 



(4) lime . Military (e.g., 0535, 1721) 



(o) Area Code . Locations of waterfowl observations will be coded in the 

 "Area Code" column. This will eliminate the need for plotting waterfowl obser- 

 vations on base maps. 



The first two digits in the area code column identify tiie general area in 

 which the waterfowl were seen. The reconnaissance level study area has been 

 divided into 24 "drainages", each of which is identified by a unique two-letter 

 abbreviation (see attached map and table). Note that in some cases roads are 

 used to approximate drainage boundaries, or several minor drainages are lumped 

 together. Also, the mining area, Nelson Creek Say and the north, middle, and 

 south sections of Fort Peck Reservoir are treated as individual "drainages". 



Tne second two digits in the area code column identify the habitat in which 

 the birds were seen. In all cases, birds seen flying overhead which do not 

 appear to be orienting to a specific water area d.TQ. denoted by a "00". For 

 birds seen using specific wetland areas, use the two-letter wetland habitat
