Modified bait stations for California ground squirrel control in endangered kangaroo rat habitat

The potential for using elevated bait stations for California ground squirrel (Spermophilus beecheyi) control in endangered kangaroo rat habitat was evaluated. Laboratory and field studies identified two bait-station designs that excluded kangaroo rats while allowing access by California ground squirrels. Traditional bait stations can be easily modified, thereby providing landowners with a method of controlling ground squirrels that mitigates hazards to endangered kangaroo rats.
