many places ! like right here in the Forrest of Bowland numbers have really suffered , though we still see them every year for about the last five years or so . Previously we where tripping over them ! They certainly had some sort of infection some sort of bug and i have seen them acting like we might with a dose of flu - Very little spaying happens on the land where i am pretty sure its some kind of bug that's effecting them . I used to bring a guy on with his hawks and shot a few Hares myself but hares do no real damage to the upland grazing , indeed the way a Hare feeds your not going to see much if any depletion of grazing by Hares.
Not against taking a couple of hares myself , i would again IF /WHEN there is an up-turn in the numbers . Its wonderful meat when cooked correctly
