This slim A4 volume is a fine piece of work, if you are of the scientific method. The graphs, the methodology, the photographs, the bibliography, all present and correct. The snag for me is that I am not of the scientific method and have trouble understanding the text, the data and the said methodology. It feels like a 'closed book' with it's own language, goals and assumptions. Further investigation (google) reveals that this 1984 publication may be the standard work in English (as oppose to Latvian,) on the dynamic eco-interface between the railway and the green sward that sits beside it. Perhaps I was expecting too much, lineside plants glimpsed from a train are a source of abiding interest to me, Mullein flashing past a speeding train, Buddleia, Mares Tail, all delightful. A cross between Thomas the Tank Engine and Rev, Keble Martin's Flora would suit me better, either that or a course in Ecological terminology just in order to unlock this puzzling portal into the scientific method . Here's a quote: 'Although some noda within the tall herb and false oat groups will be comparatively stable (chapter 3) , those developing in response to the outlined disturbances and giving rise to the observed fluctuations between groups are clearly less so.' I'm just going to look up 'noda' which is usually in italics here.
