What Grows Under the Trees
The floor of an old wood is a slower, older thing than the trees standing on it.
Ancient woodland indicators
Certain plants spread so slowly that finding them tells you the ground has been wooded for centuries. Bluebell, wood anemone, wild garlic, dog's mercury, woodruff. Some of them travel only a metre or two in a decade.
When they appear in a hedge or a scrubby corner, they are often the last trace of a wood that was cleared long ago. The trees went. The floor stayed.
You can plant a wood in a week. You cannot plant a woodland floor.
Light, and the timing of it
Most woodland flowers do their entire year before the canopy closes. February to May, while the light still reaches the ground, and then they retreat and wait. This is why the timing of a thinning matters as much as the amount of it.
Too much shade for too long and the floor becomes bare leaf litter. Too much light too suddenly and bramble takes everything.
The unglamorous layers
Below the flowers there is moss, fungi, leaf litter and a great deal of invertebrate life that nobody counts. Fungal networks move water and nutrients between trees. Deadwood beetles feed the birds. The whole system runs on things that are difficult to photograph.
A woodland is not the trees. It is everything the trees make possible.
Look down, in April. That is where the age of a wood is kept.
