The only way is communication and working with your neighbours. When all your interests are aligned and you can agree to work to the collective benefit you can do things properly and allow the good stags to breed, and the cull is on the old and poor quality.
But these days when many who buying into land are doing it for very different reasons you have great difficulties.
Here in Scotland we have the biggest land owner - Forestry and Land Scotland hell bent it seems on eradicating deer from Scotland, supported by SNH and these rewilding companies and corporates raising a lot of money to buy into Scottish land for carbon credits and milking grants to plant trees - all of which involve killing all the deer.
Many of the old custodians of the land - the rangers, the stalkers, the farmers etc many of whom have been there for generations have lost their jobs and associated housing. Their houses are now Air BnBs and any deer killing is now contracted out to contractors being paid on per deer basis hung in the larder. Contractors have no loyalty to the land - just shoot as many deer as quickly as possible with absolutely no regard to long term welfare, genetics etc.
It is utter rape and pillage in the name of …….. well I don’t know.
I have recently been listening to “this is Africa pod casts”- PHs talking with each other. Conservation, habitat management and quality and ethics are all very high on the list.
It makes me equally sad abd frustrated that the 3 bits of ground i manage have all massively affected by FLS activities. By now we normally have taken 10 to 12 bucks of those between myself and stalking friends. So far we have seen 1 buck. Not shot, but just seen. We could have shot it, but decided not to. I don’t abide by you may as well shoot it because somebody else will approach as it just doesn’t sit right.
And I expect the usual “too many deer” will be shouted by some one. There may be, in certain localities. But basing cull targets on seeing 20 deer feeding on the one patch of decent food in the district in middle of winter, or on larder returns with little control over where exactly the deer come from is not good sustainable management.
We ****ed up our fishing industry through over fishing and pollution (salmon farms etc). We are doing a damn good job with our wildlife as well. Look especially at the likes of the RSPB etc and how well their lands are doing.
Stalkers should know deer. And we should educate the landowners on proper deer management for the long term. And if all they want is eradication- advise against. If we all took this approach then we might still have stalking in a few years time - along with all the associated benefits to local economies etc etc.
