A new log seat

With the help of our granddaughter, I stacked a couple of large rounds of wood to make a place where I could sit and contemplate The Square Metre.  The lower log is an old round of sweet chestnut and the upper is from the incense cedar that blew down last year.  It has acquired a bloom of green algae in its top and I vaguely wondered how I might identify this (our native trees do not seem to develop algal blooms like this). Note also the dandelions flowering on Troy Track in front of the logs.  They appear to prefer to grow on trodden ground.

The birch tree in M3 is full of catkins, but you have to look upwards to see them well.
