Today's Guardian Country Diary describes a walk along the River Wear at Wolsingham in Weardale. Even though the riverbank woods look bare at this time of year there's always plenty to see along this stretch of river .....
... like the exquisite filigree of cypress-leaved feather moss Thuidium tamariscinum. Many woodland mosses make a lot of fresh new growth during mild spells in winter, when more light can reach them through the leafless branches.
There are often some fine fungi along here too on all the decaying wood - like these velvet shanks.
When we had prolonged heavy rain in Weardale a couple of weeks ago and the river rose very rapidly and flooded its banks. It scoured away all the dead leaves but the dead sweet cicely flower stems - which are chest-high here in summer and smell of aniseed - remained rooted but were flattened by the water, leaving a contour map on he ground of the path of the current as it had swept around the tree trunks.
Above the high water mark of the flood there was still a thick layer of autumn's decaying leaves ...
...... with bluebell leaves already spearing through.
Closer to the river the retreating water had deposited a thick layer of silt, but the buried snowdrops that grow in profusion here early in the year had already forced there way up to the sunlight and started to bloom.
When the water level falls if leaves behind these dark, temporary pools amongst the alders on the edge of the river. Sometimes there are fish trapped and the local herons are well aware of this - there are always heron footprints around the edges. In the spring toads breed in the pools and then it's a race against time for the tadpoles to develop before the pools dry up.
This stretch of river always has resident dippers and at this time of year they sing a lot, establishing their territory. It's amazing how you can always hear their song above the sound of the river - its pitch must have evolved to penetrate the background noise of the water rushing over a stony riverbed.
The riverside woodlands are constantly raided by parties of long-tailed tits .....
nuthatches ......
..... and treecreepers, all looking for insects in tree bark crevices, while ........
...... this heron, evidently out of luck in the riverside pools, flapped away to try its luck on earthworms in the fields above the river.
