Celebrating Cumbria’s Carboniferous Fells and Dales
.
Freshwater habitats
The Fells and Dales freshwater habitats provide year-round interest and include rivers like the Lyvennet and Lune and the many becks (streams) that feed into them.
Some of these are seasonal, others ephemeral. There are also ponds and small lakes (tarns), seeps and springs in ancient times some were sacred.
Visitors may enjoy fishing for Brown Trout and Rainbow Trout at Bessy Beck fish
farm. They also sell prepared fish to take away and be cooked at home.
Flowing Water (Lotic habitats)
Moisture from the Atlantic Ocean is the lifeblood of the fells. It arrives in the form of fog,
rain, sleet and snow according to the season and some filters through peat, soil and
limestone until it reaches impermeable strata, and is forced sideways and emitted through
springs like those upwellings that form Sunbiggin Tarn, also at Har Keld (Castlehowe),
Crake trees and elsewhere. Some of these were sacred ‘holy wells’ and their memory is
preserved in place names like Anna Well and Keld. Rainwater run-off from the moorland
and meadows feeds a host of ditches and small clear-running becks which in turn feed
rivers Leith and Lyvennet which feed ino the River Eden that runs northwards to flow into
the Solway, and the Lune that flows out of the area south through the Lune Gorge.
The upper reaches run shallow, fast, clear and sweet and become highly oxygenated with
exposure to the air. As they descend, they host an increasing amount of invertebrate
wildlife such as the naiads of Mayfly larva, caddisflies, damselflies and dragonflies, also
water beetle nymphs and adults and White-clawed Crayfish, in pools you might also see
horse-hair worms. Streamlined form and the ability to grasp and hang on are important
adaptive qualities in lotic wildlife. Frogs may be encountered in the moist, marshy margins,
but aren’t fond of flowing water itself. Fish species include loaches, bullheads, minnows,
trout and salmon and sticklebacks.
Mosses, algae and higher vascular water plants provide green food and living space for a
variety of small creatures.
The riparian bird life icludes Wagtails, Dippers, Kingfishers and Grey Herons; and
seasonally, the Swallows and Swifts that fly up and down the rivers hawking for flying
insects.
Restoration of meanders, surveys and conservation of water bodies and dependent wildlife is
conducted by The Eden Rivers Trust. They also offer opportunities for volunteering.

Still Water (Lentic habitats)
There are also bodies of standing
water, even at the higher altitudes and these furnish an
altogether different quality of habitat, some are ephemeral,
seasonal pools, and others are deeper permanent water
bodies like that better serve molluscs like pond snails, some
fish, microscopic flora, algaes and volvox, water fleas, water
bears and hydra, also as nurseries for frogs, toads and newts
and as home for resident and migratory waterfowl.
