Celtic Rainforest Lichens

The ‘Celtic Rainforest’ is a name given to a rare temperate woodland habitat¬† restricted to the high rainfall areas that fringe the seaboard of Western Europe. Here in the north-west Highlands the growth of epiphytic lichens, bryophytes and ferns cover the trunks and branches of most trees growing within the semi-natural oak and hazel woodlands. The quiet days of winter are a good time to focus on lichens that are often at their most colourful in the damp and humid conditions.
