BRACKEN : Pteridium aquilinum
Bracken covers great swathes of our muirland in similar proportions to grasses and heather. It dies back to a crisp grey-brown in winter. But in spring it regrows and you can watch its whole life-cycle in progress.
When mature it grows so high that it can reach should height and make progress along forgotten paths quite difficult. It can also obscure that drainage ditch or simply trip you up. However in its full glory, it is a great green sight. Unlike bracken, it is a hardy everygreen
Something else it can obscure is archaeological remnants such as cairns and hillforts. The drone pictures of Carman Hillfort were taken before it died down over the winter, but the fort outline was sufficiently clear to make it out. See index.asp?pageid=715665
The Woodland Trust tells us : Bracken is the largest of our native ferns. It’s actually a ‘Pteridophyte’ which means that though it has vascular tissue like other plants, it reproduces by spores rather than seeds. Leaves/fronds: large, green, with triangular fronds which are divided and alternate down the stem. The fronds are tri-pinnate, which means that the leaflets which grow on each side the stem are themselves divided into leaflets as are those leaflets. New fronds unfurl from the base in the spring as a trio of small leaves or pinnules. Mature fronds are upright and sturdy and on the upper surface, they are usually leathery and shiny.
Bracken is considered by some to be poisonous. While tou may see livestock and deer eat it, they get deterred when young fronds are damaged as it produces hydrogen cyanide when damaged.
New bracken rise alongside the Leven towpath. Unlike other ferns, they have distinctive main stalks and branches.
Another difference between bracken and most ferns is that the new fronds unfurl much like a tight fist rather than the spiral fiddle heads.
This example from the RSPB Loch Lomond reserve shows new bracken emerging from the grey crisp mass from last year. The stalks are already quite tall and branched with the leaves unfurling.
