Fernworthy:

Lots of what I think were ‘goat willow’ catkins.

“Goat willow – Salix caprea
This has separate male and female trees. Male catkins are clad in golden stamens; female catkins are spiky and green. Both secrete nectar – key energy for bees and butterflies in early spring.”

…and the usual suspects: my favourite stumps, lichens, violets, new leaves and so on.
