Oak is the seventh letter in the tree alphabet, standing for D as it is Duir in old Gaelic and Darach in modern Gaelic. This chunky tree is one of our best known and best loved and it provides habitat for a huge range of other species. Oak is traditionally the Lord of the Woods during the light months of the year (Holly takes over for the winter) and there is a wealth of folklore associated with it.

Snippets of lore

2 species of oak are native to Scotland: sessile (Quercus petraea) and pedunculate (Quercus robur). Quercus is latin for tree. 

Here's a guide to some of the different oaks. https://www.treenames.net/ti/quercus/oak_trees.html #ABTree

Bears used to be native to Scotland, and acorns would be an important source of winter-fattening food.

Oak has small red female flowers and long slim male yellow catkins in May – pollinated by wind.

Oaks have a second burst of leaves in July or August - ‘Lammas budding’.

At least 200 species of insects live on oak trees. More lichens live on oaks than on any other native tree.

Peel oak bark (e.g. for tanning) in early summer while it’s ‘running’ (sappy and peelable).

Powdered bark makes a gargle for sore throats, checks vomiting, helps to heal wounds and is an antidote for poisons and bites.

Oaks can be coppiced on a 24 year cutting cycle – divide the wood into ‘hags’ and cut one each year.
