The economy of not only British Columbia but, according to recent water-diversion proposals, much of western North America is dependent on the water resources of British Columbia. Because of its importance, the water resources of the province must be managed properly, requiring information on the amount of the resource, its spatial and temporal distribution, and how these factors may be influenced. Research has shown that forest management influences the yield, regime, and quality of water. A comprehensive review of such research was presented and related to watershed management in British Columbia. Legislation, administration, and problems of water management were discussed with particular reference to forest management. It was recommended that B.C. Forest Service field staff be increased and that watershed management receive greater emphasis at the Forest Service Training School, Institute of Technology, and the University of British Columbia. The division of jurisdiction between the federal and provincial governments was suggested as the reason for the passive role of the federal government in water resources. Because Canada’s present water administration is inadequate for the future, the federal government should assume responsibility for initiating action on water-resource development, and the provinces should be willing to forego some degree of provincial rights in the interest of comprehensive management of the resource. The water resources of the province were examined and four watershed- management regions were designated (Coastal, Peace River, Interior, and Columbia Mountains) on the basis of climatic factors, water needs, and flood and erosion potential. Forest-management was related to the objectives of watershed management in each region. One objective of watershed management in the Interior Region is increasing water supplies. Tree Farm License No. 9, in the Okanagan Valley was used to demonstrate forest-management effects on water yield. Yield could be increased five per cent by substituting for the present forest management one based on financial rotations and consideration of water as an important secondary product. Statistical calibration of Windermere and Sinclair Greeks in the East Kootenays was presented, and the effect of logging on streamflow from Watching Greek near Kamloops was analysed graphically. Water balance and other studies were presented for Terrace Greek watershed on Tree Farm License No. 9. Other watershed research in British Columbia was reviewed and research needs discussed. A comprehensive research program was recommended, to begin with intensely-instrumented research watersheds in the Coastal and Interior Regions. A rational mathematical rainfall-interception model was developed using forest-stand variables, most of which can be measured on aerial photos, and data from interception studies carried out in British Columbia and the United States. / Forestry, Faculty of / Graduate

Growth is associated with the availability of essential nutrients and it seems possible that these nutrients could affect the growth mechanism involved in skeletal development. To test this hypothesis 76 normal human fetuses aged 9 to 20 weeks were collected from therapeutic abortions. Sex, weight, length, head circumference, foot length and a skeletal index were recorded; developmental age was calculated from crown-rump length, and gestational age estimated from the mother's menstrual history. Bones from the right arm and leg were removed and cleaned for biochemical analysis. Calcium, inorganic phosphorus, magnesium, sodium and collagen content of 60 femora and humeri were determined, after length, fresh weight, constant dry weight and fat-free weight were recorded. Length of ossification in the bones of the left arm and leg was measured via silver radiography. Assuming bilateral symmetry, biochemical and physical data could then be compared. All fetal data were grouped according to developmental age: 9-10, 11-12, 13-14, 15-16, 17-20 weeks. Analysis of variance and Duncan's New Multiple Range Test were performed to determine the significance of group effect. Simple linear regression was executed on the whole range of data to detect which variables best predicted other variables. Maternal information was obtained from an interview and from medical records at Vancouver General Hospital. Age, weight, height, birth weight, parity and gravidity of the mother were recorded. A socio-economic index was calculated. Adequacy of maternal diet during pregnancy was assessed from a daily pattern recall, food frequency and preference questions. These data were used to calculate a total nutrition score and a protein score. Maternal data were coded as potential independent variables and multiple regression analysis performed against fetal dependent variables. As developmental age of the fetuses increased, the fresh length, dry weight and length of ossification also increased in both humerus and femur, as did the calcium and phosphorus content. In most cases long bone growth as measured by these variables advanced proportionately with fetal age. Thus group means of most variables were significantly different from each other when divided into five 2 week age periods. Water content dropped proportionately with age, reflecting bone mineralization. Sodium content fell markedly in fetal bones after 10 weeks. Magnesium and collagen remained constant. Fat extraction did not change the dry weight of the bones. Statistical correlation was found between physical and biochemical data. Generally physical variables were best predicted by other physical variables. Biochemical composition of the femur could best be predicted from corresponding data in the humerus. When gestational age was plotted against physical or biochemical variables, statistical correlation was weaker. The correlation found between fetal variables and maternal age, parity, weight and socio-economic status would indicate a diversity of factors influencing fetal growth. Whereas protein score of maternal diet was not statistically related with fetal parameters, general nutrition score showed a consistent, positive correlation with length and dry weight of the femur and humerus. This relationship was statistically significant when developmental or gestational age remained constant. The results of this study suggest that nutrition of the pregnant woman is positively correlated with some indices of skeletal growth and development of the human fetus. / Land and Food Systems, Faculty of / Graduate
