No interactions present.
I failed to add notes on the above.
Buds opposed in pairs, with a few hairs, long and narrow (6mm), >4 scales, Catkins frequent,
Stems thin and whipy, brown to black brown in twigs, distinct silver bark on trunk with many dark fissures.
watch out for downy birch too, it can be tricky to tell from silver birch
I have difficulty in identifying many trees in winter so your pictures are very useful but could you put 'buds' and 'stems' or 'twigs' in the tag box as well to help with searching. Thanks.
