1. A court may enjoin conduct which would be in violation of section 578.151 or 578.152 upon petition by a person affected or who reasonably may be affected by such conduct, upon a showing that such conduct is threatened or that it has occurred on particular premises in the past and that it is not unreasonable to expect that under similar circumstances it will be repeated.

2. A court may award damages to any person adversely affected by a violation of section 578.151 or 578.152, which may include an award for punitive damages. In addition to other items of special damage, the measure of damages may include expenditures of the affected person for license and permit fees, travel, guides, special equipment and supplies, to the extent that such expenditures were rendered futile by interference with the lawful hunting or trapping of a wild animal.
