This study has been primarily concerned with assessing a number of mycorrhizal fungi for their potential use in nursery inoculation of forest tree seedIings. This assessment has been accomplished using glasshouse and laboratory tests to determine the effects of the mycorrhizal fungi on the growth and nutrient status of Sitka spruce seedlings, and possible reasons for these effects. The importance of the soil in this relationship has also been considered. The glasshouse bioassays have shown that mycorrhizal fungi isolated from forest environments have a more beneficial effect on seedling growth in forest soils, whilst mycorrhizal fungi from forest nurseries improve seedling growth to a greater extent in nursery-type soils. Significant differences in effects on plant growth and nutrient status have been demonstrated not only between different fungal genera, but also between species of Laccaria and between isolates of Thelephora terrestris (Ehrh.) Fr. obtained from different environments. The relationship between growth, nutrient and mycorrhizal status of seedlings and the availability of nutrients in soil suggests that the availability of phosphorus in particular plays an important role in the success of the mycorrhizal association. Furthermore, it appears likely that the adaptation of mycorrhizal fungi to the availabiIity of phosphorus in their respective natural habitats may have an influence on their differing abilities to improve growth and nutrient status of seedlings grown in the different soil types used in this study. Finally, the value of the various techniques used for assessing the mycorrhizal fungi is also considered.

The overall problem with which this thesis is concerned is the alternative uses to which the woodlands of Surrey can be put. At present the majority of the woodlands are not managed in any way. The alternative uses considered were agriculture, amenity, including conservation and recreation, and forestry. The evaluation of these uses was carried out in the following manner. 1 The suitability of each use was assessed with respect to the requirements of each use. 2 A comparison was made of the benefits and inputs required for each use. 3 Finally, the evaluation was made giving consideration to the physical, economic and social factors of Surrey and the UK. To carry out this evaluation ten topics emerged as requiring detailed investigation; 1 Geographical setting and identification of the main site types in Surrey. 2 The characteristics of the woodlands in Surrey. 3 The characteristics of agriculture in Surrey. A Requirements for forestry operations. 5 The potential for increased timber production in Surrey. 6 UK and World timber supply and demand. 7 Legal framework for forestry in the UK. 8 Agriculture and the development of Surrey's woodlands. 9 The amenity value of the woodlands in Surrey. 10 The marketing of timber. Having made the evaluation of the alternative uses of woodland in Surrey the conclusion is that timber production would be the optimum use. The following are the important factors which emerged in favour of this argument. 1 There will be a rise in the real price of timber and the UK will need to increase its domestic output of timber. 2 The amenity use of Surrey's woodlands involves a high opportunity cost. 3 Surrey's woodlands can play a role in increasing the volume of home grown timber.
