On public land here we can pretty much do what we want as for stands but all structures have to be removed by the end of December of each year. Spring bear starts around end of april so many are put up again. This law just came into place a few years ago as it used to be a free for all. Permanent structures that were built before this law were not taken down so there are a few in the bush but they are in very poor condition. Private land you can do what you wish as long as you own it or have permission and leave them there all year if ya want. Here's a pic of one of my stands on my land which i have arrowed 2 elk out of.
