GOLDEN rule is not to touch ecosystem balance but somehow if you hunt deer regularly then you can help to control the number of the wolves in the area for both species good. If the population of the deers is too much then you better to hunt deers instead of wolves, by hunting wolves you help the deers to achive great population which is bad in food less areas....
We here hunt grey partridge, francolin, rabbit and so... ( 11 weeks and only sunday, thats makes 11 day hunting for whole year.) There is to much hunter here and partridge population went down few years ago, after that we start to hunt magpies and crows to help the recovery of the grey partridge population. We also started to produce grey partridge in cages and the we let them go. This year is the second year of this application and adaptation levels going higher. So if you will touch the balance of the nature you have to calculate it very carefully.
But Amphibious my friend, hunting animal for pelt is something that i can not tolerate.... I am sure tigers, cheetahs, jaguar, leopards pelt worth much more, then let the hunters hunt them again....Don't forget, those animals were not endangered before pelt hunters...
