Ben Easley told me today that kangaroo rats are not much
of a problem in Kern County, only on a few occasions has it
been necessary to make a special project of poisoning
kangaroo rats. Last year his force oversaw an operation
where kangaroo rat poisoning was done by airplane. This took
place in the summer time on a half section of land to the
southwest of the Rancheria area about five miles. Mr. Easley
tried to set about three pounds of poison scattered on each
acre of land. We stretched a 20 (Twenty) foot square
canvas on the ground and as the plane flew over it dropped
about three kernels of whole grain barley on this
canvas. He and his crew watched this poisoned area
for three mornings following the application by plane, two
mornings immediately following the application and
the third morning of inspection came after two days at
a weekend separated the inspection dates. He said
that no scavenger or predatory birds were noted
in this area on any of the three inspection trips
following the application of the poison, nor did they
find many dead rats. Easley thought 3000
numbers of rats had been killed with the poison but
that nocturnal scavengers removed them by daylight.
Strychnine poison was used in this rat poisoning project.
I forgot to enter our seeing and photographing the parts of forty (40) adult
sheep that were hanging on a barbed wire fence to the south of the road on the Woody
Famosa roadway about one mile east of highway 65. No carcasses could be seen
in the area.
