A lovely day up at Glentrool, checking on ripening birch seed for the UK National Tree Seed Project.
As the photo shows you can often find a multitude of rowan saplings around the base of oak trees.
This not just coincidence.
Birds from the Thrush family such as redwings which have been feeding on rowan berries deposit the seeds in their droppings whilst sitting in the oaks.
These often germinate well as the act of the seed passing through the birds’ digestive system helps to break down the seeds dormancy.
