To add to the excellent info Dwayne has given:

---You can buy one resident sheep tag ($60) per year, good for one sheep, Bighorn, California Bighorn, Stone or Dall, LEH or "open" unit.
---The sheep tag allows you to hunt any open season (non-LEH) anywhere in the province, or for your area specific LEH ($6 application fee, non-refundable), or both until you shoot a ram, filling your tag.
---There are zero non-LEH areas for Dall sheep...unless you find an "all white" sheep in a non-LEH Stone area, which is seems to be very unlikely.
---Most Stone sheep areas are non-LEH so open for hunting Aug 1 to mid-Oct. LEH areas maybe more restricted on season length (thinking of the Spatzizi area with two week long draws)
---Bighorn and California bighorn are a mixed bag of non-LEH and LEH with more areas going LEH all the time. Seasons are about a month shorter for Bighorns than Stones.
---They have been a few ewe tags given out for the Kamloops Lake herd(s) in the past. Not sure about this year.
---Archers are lumped together with all the other hunters in virtually all the areas but one.
---I've seen some residents use horses for access up north, but it seems fairly rare.
---Some residents hike in deep...several days from the river, road or fly-in lake. Better be in good shape for the pack-out if you get lucky!
