1 INTRODUCTION 1 April 1979 to March 1980 has been the fourth year of a five and a half year contract between the NCC and ITE, aimed at describing the structure and distribution of ecosystems occurring on British Rail land. The work was initiated_because recent.radical changes.in railway verge management andtrack usage have almost certainly involved profound alterations in vegetation structure and composition, and, consequently, in the kinds of habitat provided. It is recognised that semi-natural, ungrazed and now only sporadically managed railway verges provide a useful refuge and migration corridor for both plant and animal species; but there is little documentation for the kinds, numbers and distribution of species involved, and even less information about the effects of change. 1.1 The scope of the survey \ A detailed discussion of why and how the railway survey was begun is given in the First Interim Report (Way & Sheail 1977), where a general description of changing permanent way management practices will also be found. After an exploratory field season (1976), the survey was designed to allow a single year to examine each of the five British Rail Regions, with the exception that Southern and Western Regions, with lower track mileages, be combined. During 1977, Eastern Region was surveyed (Way, Sheail & Mountford 1978), whilst 1978 was spent looking at Southern and Western Regions (Sargent 4 Mountford 1979), and the field work described in this report was carried out on the London Midland Region in 1979. It is planned to survey Scottish Region during 1980, and to combine.and analyse information from all Regions prior to preparing the final report during 1981. 1.2 The current year Much of the desk work during the current year was concerned with the design, introduction and testing of a stratification system. The results are discussed in Section 2. Section 3 describes the survey of London Midland Region, whilst some general conclusions are drawn and areas for future attention outlined in Section 4.
