What's in a bog?

Five discoveries-in-waiting for the keen-eyed bog traveller

  1. Carnivorous plants

    Peat bogs are generally acidic and low in nutrients so plants have evolved to get their vitamins and minerals in a different way. Bog-loving sundews, butterworts and bladderworts trap insects in novel ways and digest them for their natural goodness.

  2. Ancient trees

    The remains of trees, including pine and oak thousands of years old, have been revealed in bogs and fens across Britain, a tale of the past when woodland thrived in now-treeless landscapes before changes in climate and human activity prompted their demise.

  3. Flights of fancy

    Peatlands are crucial places for the congregation of birds including breeding wader birds such as golden plover (below), dunlin, green shank and Arctic Skua, and raptors on the hunt, including hen harrier, short-eared owl and golden eagle. Dragonflies, damsel-flies, mosquitoes and other insects may all be spied.

  4. Bog bodies

    Peatlands have proved perfect preservers of dead people. Human sacrifices and wealthy princes have been uncovered in bogs across the world, mostly in northern Europe. The oldest is Koelbjerg Man who lived in Denmark 10,000 years ago. Cashel Man, found near Cashel in Ireland, died around 2,000 BC. Lindow Man, found in Lindow Moss in Cheshire, was probably alive just before the Romans came around 2BC.
  5. Bog moss and berries

    Spectacular sphagnum mosses (pictured below) and wispy cottongrass are the most common plant of the peatlands. But healthy bogs can be a feast of tasty berries such as bearberry, crowberry and bog bilberry. Fungi is a feature of healthy peatlands, as mycorrhizae under the surface and as visible mushrooms and lichen. More than 600 species of fungi have been recorded in bogs and fens in the Northern Hemisphere.
