Senate Bill No. 478 amends existing laws regarding the management and removal of feral swine and other nuisance wildlife in Oklahoma. The bill requires individuals to obtain written permission from landowners or agricultural lessees to remove feral swine from both private and public properties, eliminating the previous requirement for a permit to kill feral swine at night. Additionally, the bill removes the ability to maintain certain firearms for nuisance control and allows for the control of nuisance wildlife without a permit under specific circumstances, while also making the language gender-neutral and updating statutory references.

The bill also repeals a section related to special permits for private property owners to kill feral swine and introduces new provisions for managing depredating animals using aircraft, including the requirement for a daily flight log and notification to the Oklahoma Department of Agriculture, Food, and Forestry prior to management activities. Furthermore, it establishes penalties for violations, including the revocation of permits and potential fines. The act is set to take effect on November 1, 2025.
