I personally don't hunt moose in the swamps and bogs.I hunt them in the foothills or mountains or on agricultural fields where access is much easier and you can get much closer to the animals.There are however some people that do hunt moose in swamps and bogs that are similar to the pictures that you posted.However for the most part there is much more cover available in most of our good moose areas.In the prime western Canadian moose areas a hunter will see several bull moose every day with some in the 50" range.
