More Likely Lichens

Lichens come into their own when other organisms become seasonally dormant.

The show of lichens is likely to be greater than in the years when J.G. Graves first gave Blacka to the people of Sheffield which was before the smoke control legislation came into force from the 1940s on. Certain species survived better under the conditions than others which had a very low tolerance of sulphur dioxide.
This powdery grey covering (below) is on the lone beech just to the east of Cowsick.

The hopes that a few of us have to see more of the beech seedlings develop into trees here are likely to be dashed by the intrusive management of SWT who will continue with their "we know better than nature" policy of bringing in more and more livestock to eat up all unwanted growth.
