I collected some Scots Pines from an area of bog where they had naturally seeded in the last 30-40 years or so. There are mature trees in a nearby drier location which provide the seeds. The seedlings germinate and grow up to 6 feet but then seem to mostly die slowly due to the wet conditions. The largest tree I collected had been driven over by a tracked machine in the past few years and had had some roots torn at the time. It's a bit sickly looking and I'm not that confident, but I've had good success with similar bog pines before so fingers crossed.
