@JMikeyH...
Stalking pigs is extremely challenging but can be rewarding. But I think the environment you have at hand probably doesn't lend itself to pig stalking as well as it does here or in Aus. Down here, we get to spot pigs from afar, in open ground, affording the chance to stalk in close if that's the way you're inclined. They will root and cock about in pasture if they don't get much pressure, and can be remarkably unaware if you're downwind and quiet. I've snuck up to really some big pigs - the kind that can eviscerate you in 3 seconds of mayhem - usually for the purpose of taking some photos to show my pig hunting buddies. Fact is, sneaking up and shooting a big pig isn't anywhere near as much fun as catching it with our dogs, so we don't tend to stalk then shoot very often at all.
In the woods / bush / forest, can be next to impossible to find on a random hunt, unless you spend days prior working out their territory. Pigs are very intelligent creatures, but also creatures of habit. They will move around their territory on well established pig trails, and learning pig sign is very useful to see where they go. You can often follow pig sign (we call in "mark") to wallows and favourite rooting spots. If you know where they hang out, then you can put yourself in the right kind of area and use your senses to locate them - hearing and smell often before sight. When they are actively feeding in a mob, you'll hear them before you see them.
Don't know how this would work out in the UK, but no harm in finding out.
