weeks' field season which included a training and familiarization program in 

 addition to the work program. 



During the winter, the first forester mapped the Combermere map area 

 and adjoining areas totalling 1, 800 square miles, and during approximately the 

 same period the second forester mapped approximately 1, 200 square miles. 



In addition to mapping landtypes, the site research staff compiled in- 

 formation regarding (1) the potential productivity of the sites which make up 

 each of the major landtypes of the region, and (2) the ecological interrelation- 

 ships of soil, climate and forest which control forest productivity of each major 

 landtype. This information is being incorporated in a publication, "A Guide to 

 the Site of the Middle Ottawa River-Georgian Bay Region". 



The Reforestation-Research Co-operative Program 

 A forester who had previously concentrated on forest mensuration, spent 

 a large percentage of his time assisting in the designing of experiments and assess- 

 ing results in broad- scale reforestation projects. The chief of these was the 

 plantation assessment program on shallow soils in the Lindsay district. A re- 

 port of the co-operative underplanting and release experiment in the Petawawa 

 Management Unit has been presented in Section Report (Forestry) No. 10. 



Site Research in the Wildlife Research Area, Algonquin Park 

 A map of the physiographic sites of the area was finalized with a key. 

 A short report will be written next year. 



Cull Inventory Co-operation 

 Training and direction in site classification were given to the two party 

 leaders working on cull inventory in the Haliburton region under the direction of 

 a member of the Division of Timber Management. The sites were grouped to 

 facilitate a study of the relationships between site conditions and the incidence 

 of cull in hardwood in the South-Central and South-Eastern administrative regions.
