The silver pipe is for the central heating which was installed about 5 years ago at work. Before then this flat roof was devoid of virtually all vegetation other than a little bit of moss. I find it fascinating that this one pipe has created such a micro climate. First there was a thin covering of moss, uniform in shape and only of a couple of species as far as I could tell. Then over time other plants have come along, so now there are ferns, succulents and what looks like a millet or some other grass, presumably coming in from a bird. One day this will all need to be cleared away as it must be having an effect on the waterproofing feature of this flat roof, but for the moment it is a lovely micro-habitat developing nicely inside the BBC.
