I wish I was in this position really.
I used to shoot a property I would see 30 plus deer a night (phenomenonal numbers of deer for the region) while shooting rabbits.
Owner was protective of the deer as he had had his fence cut years ago letting some into doc mismanaged land.
He was always hopefull he would get some back into the deer trap near the boundary.
The deer trap used to work when it was freshly developed land with new grass 25-30 years ago.....they had no reason to go there now with freshly developed grass and crops over the property.
For a start it was yea you can shoot a deer but only a stag.
Crops started getting punished....ok you can shoot a hind but if you get a few I would like some sausages.....like no problems at all how many can you handle.
Numbers dropped rapidly.
Dependant on the terrain and bush and thesize of
the property I still believe letting rec hunters on property to hunt is the most economical and most ethical solution.
No disrespect to the opening post at all, when numbers are up as much as yours the jobs got to be done.....it just should never get to that point.
But the "job" wouldn't be a "job" and wouldn't have to be done if Access was allowed its that simple.
Sorting the hunters and or pest controlers from the fuckwits with a rifle and or lamp/thermal who can both hunt safely and follow instructions to to "shoot everything" " only shoot stags" "only shoot hinds"
Is the hard bit for the land owner/manager
weather you personally think their goal is off target or not is irrelevant if you have access follow the rules.
