All great comments / advice. Like RR says, hunting over great ''active'' sign is a sure bet. Although some people still misinterpret sign.
An adult moose eats about 60lbs of leaves a day. Contrary to popular belief, only about 5-8% of their diet consists of aquatic plants.
Your little moose haven should have the following 3 components:
A 5 to 15yr old cut, providing a smorgasboard of food, this is where most of the cows/calves/yearling bucks will spend 90% of their time. This is why calling from a cut works really well, perfectly natural the cows are bedding / feeding right in that stuff;
Proximity to water (a brook, a bogan, a cedar swale, etc); Moose drink a lot of water;
Proximity to cover (here you're looking for a dense coniferous thicket or cedar swale). Moose have to regulate their body temperature, being such a large animal, and this habitat in extreme heat condition (above 20 Celcius is the treshold), moose will seek these shelterbelts to cool off.
For me, one of the best tools that has had a tremendous impact on our success rate is the trail camera.
If you can setup 3-4 sentinel cameras in potential spots, this invaluable tool will give you an EXACT inventory of what's roaming that parcel of land.
For example, you would be amazed at the sheer amount of sign 3-4 moose leave in a concentrated area. A properly positioned trail cam will reveal how many moose reside in the area, and the composition of the herd.
Our trail camera surveys have revealed in the last 3-4 years that one particular spot holds 10-12 moose, while other spots only have a cow and a calf.
Good luck in preparing your hunt, it is the best part of the journey!
