I agree that there are those that do not respect landowners properties and poach. It has been a long time effort to talk to land owners to be granted permission to hunt. I have gleaned permission to many posted properties that others were turned away. Landowners pay the taxes and their livelihoods depend on their properties in many cases. When permission is extended it is the hunters responsibility to act properly, do no harm to fields, haul out all trash brought in and in some cases haul out more. This, in itself can garner landowner respect for the hunter that has permission.
Now, I have not paid a trespass fee to hunt in my 50 yrs. plus of hunting afield. It is not my mantra. I respectfully ask for permission, if a trespass fee is required I respectfully thank them for their time and decline. I have offered work to hunt and this has been a valuable tool. I am a retired electrician and tell them that they buy the materials and I will do the work. This has worked very well. I have done field handwork, mechanical work, fencing and more. But, I decline to pay a trespass fee.
My hunting future is diminishing with my age. I have doubts about the future of hunting. I have concerns that hunting will continue for future generations. But, if the hunter puts his/her right foot forward it will help. Perhaps not all, but help none the less.
