I can see this is a problem that stretches across the globe.
I am a UK deer manager that with two others culled over 650 Fallow from an estate in southern England last season and offer my own perspective on what seems to be a common problem.
1. You will find it difficult to solve the problem with recreational stalkers. The level of skill and commitment required to achieve big culls is rarely found in the sporting community. It requires long hours. I stalk 6 days a week during the season.
2. This level of commitment needs to be paid for. This can be a combination of meat value and grant funding. The powers that be (government, environmental bodies etc) need to accept the necessity for deer management and they need accept that it needs to be paid for.
In Nature Scotland mandate that landowners have a responsibility to manage deer and have the right to enter land to conduct culls if not achieved. The landowner is billed for this cull.
3. Meat needs to be given value. There are a number of initiatives going on here to enhance a valuable resource. Supply to schools, prisons, military facilities etc. Venison marketing to show it as the healthiest red meat option
4. To ensure that it is healthy personnel need to be trained/licenced to inspect and process it in approved/licenced facilities with appropriate checks (vet inspections) in place. This training needs to also include training in culling. This is not a big deal and can be achieved in a few days.
5. Seasons - No seasons will not solve the problem. The are there to protect animal welfare (protection of dependent fawns) but extending/abolishing the male season will all deer managers to concentrate on females when they are in season
As I mentioned in the title. This is a personal perspective that might offer points to consider in your debate.
