The tree stumps you see in the photos are birches that didn't survive the rising water level in the peat bog:
Olympus Stylus 1s, 120mm, ISO200, f5.6, 1/125s
Olympus Stylus 1s, 75mm, ISO100, f8, 1/250s
Olympus Stylus 1s, 110mm, ISO100, f8, 1/400s
No doubt, more young birches will try to gain a foothold in the bog and suffer the same fate.
