Final answer:
For hunting on private property or a grazing lease, one should only enter with written permission from the landowner or leaseholder, respecting property rights and considering wildlife conservation.
Step-by-step explanation:
When you come upon private property or a grazing lease that you would like to hunt on, you should only enter after receiving: a) Written permission from the landowner or leaseholder. This approach not only follows legal protocols but also respects the property rights of the landowners, who may have incentives and concerns related to the protection of endangered species or other wildlife on their property. In light of potential liabilities and the need to conserve wildlife and their habitats, securing written permission is both a legal and ethical consideration in hunting and wildlife management.
