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 from the Department of Wildlife Conservation for nighttime removal. 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.

Furthermore, the bill repeals a previous section that required a special permit for private property owners to kill feral swine. It also introduces new provisions that allow landowners and agricultural lessees to control nuisance wildlife, including feral swine, without a permit during the day or night, except during designated deer hunting seasons. The bill establishes penalties for violations, including the revocation of permits and potential fines, and mandates that any hunting or fishing licenses be automatically revoked upon conviction of certain violations. The act is set to take effect on November 1, 2025.
