OUTLINE OF THE CAREER OFA. S. WATT Alexander Stuart Watt was born in Aberdeenshire in 1892. Educatedat local schools, he went on to Aberdeen University where he studied for the BSc (in Agriculture) and MA, graduating in 1913. He obtained a Carnegie Scholarship to study in Germany but his plans were frustrated by the outbreak of war. Instead he entered Cambridge University to study for a BA by research underA. G. Tansley, his subject being the failure of regeneration of British oakwoods. In 1915, after the statutory yearin Cambridge, Watt returned to Aberdeen to take up the post of Lecturer in Forest Botany and Forest Zoology. In March 1916 hejoined the Royal Engineers. His army service ended early in 1918 when he was badly gassed, an experience from which he neverfully recovered - thereafter he had only onefunctional lung. Watt went back to Cambridge to complete the residence requirements for his BA, which he received in 1919, before returning to his post at Aberdeen. Having been assured there would be no further residence requirements for the newly introduced PhD degree, he then registered with Cambridge as a PhD student. Watt was awarded the degree in 1923. He left Aberdeen in 1929, to take up a post at the Imperial Bureau of Entomology, Farnham Royal, Buckinghamshire, before a few monthslater accepting an invitation to become Gurney Lecturer in Forestry at Cambridge University. He was transferred to the Botany Department in 1933 as Lecturer in Forest Botany, a post he held until retirement in 1959. He continued active research into the 1970s. In 1957 Watt was madea Fellow of the Royal Society and in 1960 an Honorary Fellow of the British Ecological Society. He died in 1985. types of grassland. In the course of this work Watt becameinterested in the behaviour of bracken Watt's first research began at Cambridge on the failure of regeneration in British oakwoods. He received the Cambridge BA for this work and then went on to study the same phenomenonin beechwoods and yew woods at Aberdeen. This research widened into interest in the general ecology of woodlands. On his move back to Cambridge in 1929 Watt began research into the ecology of the Breckland area of north west Suffolk and south west Norfolk studying the soil factors determining the composition of vegetation and later the effects of grazing by rabbits. Over an extended period from the 1930s to 1973 he madedetailed study of the changesaffecting different A. S. Watt NCUACS 38/6/92 and studied the stages by whichit advancedinto grassland. From this work he was to develop a general concept of ‘dynamic stability’ in the plant community, envisaging it as a patchwork of vegetation at different stages of a repetitive cycle of composition. DESCRIPTION OF THE COLLECTION The collection is presented in the order given in the List of Contents. The collection as a whole provides good documentation of overforty years of research in Breckland ecology. Section A, Notebooks, is the largest in the collection. Most date from Watt's work in the Breckland area from 1931 to the 1970s but there are also notebooks recording earlier research on the regeneration of British woodlands and a few from visits overseas, including a visit to Germanyin 1931, also documented by a series of photographs (Section E), and a visit to the Sudan in 1965-66. Section B, Notes and drafts, consists almost entirely of material relating to Breckland from 1931 (an early research proposal) to 1975. The largest single componentofthe section is the collected notes, data and correspondencefor an article by Watt 'Rare species in Breckland: their managementfor survival’, published in the Journal of Applied Ecology in 1971. Thereis also little material from Watt's vist to the University of Colorado in 1963. Section C, Nature Conservancy,principally documents Watt's service on the Breckland Committee of the Nature Conservancy from 1958, andhis involvement with work carried out 1966-c.1970 by Mrs G. Crompton oncollating the results of previous studies of Breckland. Section D, Correspondence, is very slight. T. E. Powell P. Harper Section E, Photographs, comprises a variety of photographic material 1931-73, principally relating to Watt's Breckland research. Ofparticular interest is a set of photographs taken by Watt on visit to the heathland of north west Germanyin 1931. BATH 1992 Section F, Maps, includes detailed plans of a number of the Nature Reserves in the area of Breckland in which Watt worked, including some of Lakenheath Warren, the site of most of his experiments and observations. Thereis also an index of correspondents. A. S. Watt NCUACS38/6/92 SECTION A NOTEBOOKS Although dates and locations of work are generally given, there are very few subjecttitles in these notebooks. Intercalated material in the volumes mayinclude Watt's own page markers, notes and data, and pressed plants. Some of the notebooks have soil samples smeared on the pages. The nature of Watt's research entailed observing plots of vegetation over an extended period of time This is reflected in Watt's use of his notebooks. Many were used to record data over manyyears, and include subsequent reassessmentand correlation of data.
