THE SURVEY                                                              
       Maroh, 1930 
 
        la_ckRabbj~_      charda       ah.--R. S. Zimmerman, leader of rodent
control in 
 Utah, reports that in response to a request from orchardists along the foothills
of the 
 Wasatch Range adjacent to Brigham City, a campaign for the control of jack
rabbits was 
 conducted early in February. Jack rabbits have been particularly destructive
in the newly 
 planted orchards in this area. Several thousand trees died after being girdled
during 
 the winter of 1928-29. One orchardist lost more than 1,000 trees in 1929.
In the spring 
 of 1929 he planted 2,500 young trees and protected them with mesh wire.
When the snow 
 became so deep, however, that the wire protectors proved ineffectual and
rabbits began to 
 damage the upper branches, he requested assistance from the Survey's office
in Salt Lake 
 City. At the time poison was placed along the foothills between Brigham
City and Perry, 
 the snow was about two feet deep. On the night of February 4, a line of
poison was placed 
 at right angles to the rabbits' trails leading from the mountain side into
the orchards. 
 The area was revisited on the following morning and good results rewarded
the efforts of 
 the previous day. Additional bait was placed in ravines and small draws
leading down from 
 the mountain. The owner reported later that no further damage was sustained
by the or- 
chard.
