as a result of identification of species, general reconnaissance in 

 connection with the land development survey, and ecological 

 investigation by the tsetse department. The enum.eration of grow- 

 ing forest stock has been carried out for nearly all the Kilimanjaro 

 forests and those of Minziro, most of the Shume-Magamba forests 

 and part of those on Meru; also for considerable areas of forest on 

 public lands, containing stocks of Chlorophora and Khaya. In Kenya 

 the identification of species in the forests is practically complete, 

 but no wide-scale stocktaking has been done. Working plans are 

 restricted to the forest areas which are being intensively exploited 

 and to the considerable area of plantations. In Uganda a working 

 plan has been laid down for the Budongo forest as a result of aerial 

 photographs which have revealed the extent of growing stock. 

 This is one of the few cases in Africa where air survey has been 

 used for this purpose (Uganda 1934, D.R., p. 14). 



In Nigeria an extensive enumeration survey of forest reserves is 

 nearing completion and this will enable stocktaking to be put in 

 hand over a large area, but at present only a small region is under 

 working plans. A notable study has been made by W. D. Mac- 

 Gregor (1935) of the silviculture of mixed deciduous forests. For 

 the Gold Coast important studies were made many years ago by 

 H. N. Thompson (19 10), and forest ecology has been placed on 

 a sound basis by T. F. Chipp (1927). The valuable collections by 

 officers of the Gold Coast forestry department, and in particular 

 by C. Vigne, have provided a good working basis for enumerations 

 and stocktaking. The enumeration of trees in selected areas has 

 been begun and 735 square miles are under administration plans. 

 Stocktaking and exploitation are in progress in Sierra Leone. 



Finally the comparatively small high forests in the Anglo- 

 Egyptian Sudan along the Blue and White Nile were surveyed in 

 1928 and 1930, and a scheme for re-afforestation along the Blue 

 Nile is being put into operation. The extent o^ Acacia senegalSorest 

 in the Sudan has been estimated at some 50,000 square miles. 



For the French territories there is not much information available 

 in print. In 1932 Aubreville published an account of the forests and 

 the reserves of timber in the Ivory Coast, and in 1936 an illustrated 

 book on the forest flora of that country. The numerous publications 

 by A. Chevalier (notably 1905-13 and 1920) are also of great
