coyotes do noc ordinarily consume neck areas. Dessit2 intmsive
searches, non-tar2et deaths r2sulting ircm tzsts with the collars
have not been observed by FdS and it is conciuded that the probability

use <strong>of</strong> 1080 in toxic collars is r2mo~2.
51 . Exposure <strong>of</strong> SiD bai~s containing 1 C.80 t3 con-tarset ~,vi?bl i fe &?ends,
<strong>of</strong> course, on the rate <strong>of</strong> application and upon whether the baits
are covered. In this connection Souch gakota's application ~nvisages
a maximum <strong>of</strong> 10 SLD baits per square mile, ,Wontana's applicaticn
contemplatss 3 ?axinurn <strong>of</strong> 25 bai c; 3er square mile and ',Jycninc's
appl ication apparen~l y ccntmpl at$s that the number <strong>of</strong> bai cs wi 11 be
left to the discretion <strong>of</strong> the czrti fied appl ica~ors. \iidespread
appl ication <strong>of</strong> such baits would, <strong>of</strong> course, i ncr~ase their ~x~osure
to non-target species. While such zxposurs cculd .? reduced if the
baits were covered, covering <strong>of</strong> the baits increases the di ifi C U ty ~
<strong>of</strong> retrieving uneatened baits and <strong>of</strong> monitorins the use <strong>of</strong> such
baits. AST4 Method i-590 (1976) recovxnends that SLD baits be covered.
42. Because the use <strong>of</strong> 1080 SLD baits apprcved herein is upon the assumption
that such use will be limited and for the purpose <strong>of</strong> taking particular
depredating coyotes rather than as a coyote population suppr,ession
technique, the risk <strong>of</strong> non-target exposure under such circumstances
is considered to be minimal.
