Pteridium aquilinum

Close up look at Bracken

How to spot

Bracken is the most common fern in the UK. A long-lived extensively spreading plant, it can grow up to 2.5m.

It has long fronds with pinnate leaves, which means they have one long stem in the centre with small leaves coming off.

This species, unlike other fern species, dies back in the winter, with it’s leaves turning brown. In the spring Bracken fronds appear tightly curled and slowly unravel.

Where to spot

Bracken is a common site all around the UK – but it’s not just in the British Isles that it can be seen, this species is found on every continent except Antarctica.

Here in the British Isles, it can be found in moorlands, woodlands, heathlands, and even pastures and abandoned agricultural land.

Things you might not know

Bracken has fascinating folklore and can be linked to a number of different cultures and religions.

One of the most interesting mythologies around this species is that it was said to hold the power to turn people invisible! Bracken reproduces using tiny spores rather than seeds. The story goes that holding the spores of bracken could make you as invisible as they were.

Reindeer Moss

Cladonia rangiferina

Despite its name, reindeer moss is actually a lichen (in fact it is also known as ‘reindeer lichen’).

Composed of many light and dainty branches, it grows in cushion-like tufts. When dry it can be quite brittle but once wet it becomes somewhat sponge-like.

Where it grows

Reindeer moss is usually found on moors and heathland, often growing in pockets of soil attached to rocky outcrops.

Best time to see Reindeer Moss

Reindeer Moss can be spotted all throughout the year.

Something you might not know

The only naturalised reindeer in the UK are found in the Scottish Highlands where they live for much of the year on reindeer moss.

Other Species

String-of-sausages Lichen

Usnea articulata 

  • Grey-green tassels of up to 1 m hanging down or draped across the substrate but rarely anchored to it.  
  • Main stems have inflated sections which are pinched at intervals, and so resemble a string of sausages. This is a key feature to look for as there are other pendulous Usnea species but none have this characteristic.

Habitat

It is most common in the south west’s temperate rainforest zone. 

Favouring well-lit conditions and dry, open situations, it is most often found in tree canopies or on lower branches where trees are well-lit, in woodland or on scattered trees in open moorland. You can also find it on the ground after stormy weather. 

Similar species

Other large, bearded lichens include Usnea ceratina, Usnea dasopoga and Usnea hirta but these lack the sausage-like lobes. 

Did you know

  • It is a Section 41 species which means that it is considered of “principal importance for the conservation of biodiversity in England” under Section 41 of the Natural Environment and Rural Communities Act (2006).
  • A clean air indicator, rare outside of south-west England’s rainforest zone. Highly sensitive to sulphur dioxide pollution, it was once much more widespread in Britain but now appears to be making a comeback, perhaps due to improved air quality and a warming climate. 

Distribution 

Largely restricted to south-western parts of the UK with most records in south-west England.
